Inventory Management is an enterprise-wide discipline concerned with the identification and tracking of Information Services (IS) hardware and software assets. Its three main areas of concern are:

Acquisition.

Redeployment.

Termination.

Figure 1. Asset Management phases and operations

Acquisition procedures are established to assist personnel in procurement of software and hardware products. Its main purpose is to ensure that proper justifications are performed and that financial guidelines are followed. Acquisitions require “Purchase Orders” to track and authorize the purchase, while the actual installation of equipment is performed by the Infrastructure or Facilities Management Department. Once added to the environment, a Master Inventory record is created to describe the newly added equipment and its components (i.e., Pentium IV PC with 512 MB or RAM, a 40 GB Hard Drive, CD Drive, Floppy Drive, Sound and Video Cards, a 56 KB Modem and a 10/100 Ethernet Connection, etc.). Inventory records can be used to calculate the resale price of existing equipment, when planning for an upgrade / replacement or reduction in size. The Inventory Report can be used to inform buyers of your stock and obtain bids on the purchase of your surplus equipment.

Redeployment procedures are responsible for ensuring that assets are tracked when moved from one location to another and that budgetary considerations are adjusted as needed. Should a product be moved in from its original owner, then the Inventory System is updated to reflect the new location and owner. In this case, the old product is deleted from the original owner's budget and added to the new owner's budget. If equipment is being deployed from one person, or location, to another, then a data wipe operation must be performed to insure that sensitive business, personal and/or medical information has been deleted. If data wiping procedures are not performed in accordance to Department of Defense standards, then the company is open to legal and civil penalties as defined in a number of laws (i.e., Sarbanes-Oxley, Gramm-Leach-Bliley, HIPAA) Redeployment requests can generate transportation activity (pick-up and delivery of equipment), facilities management activity (disconnecting device, data wipe, reconnecting device, etc.), inventory management update, and service activities associated with the device(s) being moved.

Termination is responsible for deleting the asset from the inventory when it is discontinued, or replaced. The owner's budget will be updated to reflect the asset termination and the asset will no longer be listed when location reports are generated. Whenever equipment is being terminated (even if for donation to charities or employees) a data wipe operation must be performed to eliminate any sensitive information from the hard drive. Additionally, a certified vendor must be utilized to insure that the computers components are disposed of in an environemtally friendly manner. This scrapping process must be certified, so that legal and civil penalties are no longer the responsibility of the terminating firm but rather the scrapping organization.

The Inventory System is maintained within a data base that ties an asset to its owner and defines the location where the asset resides. The relative importance of the asset is added to the inventory record in a Criticality field (i.e., Criticality = 1-5, where 1 is "Most Critical") and the current status of the equipment is indicated via a status field (A=Active, R=Redeploying, D=Donated, T=Terminated, etc.). Based on this information the contingency planning specialist can plan asset recoveries needed to support critical business operations and the facilities management group can schedule work events associated with equipment status changes (i.e., from A to R, or A to T, or A to D, etc.).

Like all data bases, the Inventory System will only be effective if its information is kept current. To ensure the accuracy of the Inventory System, while not adding too great a burden to company personnel, every effort must be taken to implement processes that maintain inventory data with a minimum work effort from personnel. To that end, we suggest automated form tied to equipment status and criticality changes, so that facilities management and business continuity planning can adjust their functions accordingly.

Inventory Management provides:

Up-to-date information about data processing resources through the creation and archiving of records in a centralized repository.

Financial records specific to a single component, or groups of components.

Component Status Indicators to identify a component as Active (A), Redeployed (R ), Donated (D), or Terminated (T).

Component Criticality definition (1-5, with 1 being most critical).

Service records for all components in the inventory.

Data used to support configuration diagrams of the hardware and software components contained within specific locations, or the entire data processing environment.

Reports can be generated from the Inventory and Asset Management Systems that would project the amount of revenue that can be generated through the sale of surplus equipment, or to define the number of components that have a criticality rating of ‘1’ so that you can project the costs associated with maintaining duplicates of critical equipment at reovery sites. Combining the two reports would allow you to reroute equipment being scheduled for termination to the Recovery Facility and eliminate the additional costs associated with purchasing duplicate equipment in support of recovery needs.

1.1.2. Scope

The Inventory Management discipline encompasses all system and data network elements from the mainframe to the server level throughout the enterprise.

All mainframe and data network based hardware and software assets must be identified and entered into the Inventory System. Any changes to these environments must be reflected in the Inventory System.

Financial and technical product information must be available through the Inventory System, as needed to support the functional responsibilities of personnel within the finance and contracts management departments.

Asset criticality must be included with asset descriptive and financial information, so that the Recovery Management department is supplied with the information it requires. Recovery actions must be implemented to safeguard critical assets.

Asset status must be included in the Inventory Management system, so that the component(s) can be serviced in adherence to legal, environmental, business, and industry requirements. This process should be used to drive the facilities management department via form routing when components change status from active to redeploy, donate, terminate, of scrap. An audit trail of activities associated with equipment status changes and associated actions must be maintained to certify actions and eliminate legal and civil exposures.

The Standards and Procedures Manual section relating to Inventory Management must be created and published. This section must describe the process by which assets are identified, entered into the Inventory Management System, tracked, and finally deleted. All information needed by personnel to perform Inventory Management functions must be clearly described within this S&P Manual section.

1.1.3. Mission

The mission of an Inventory System is to provide a Central Asset Repository of information used to define assets and relate the asset to its; owner, location, and relative importance. This information will provide personnel with data needed to support their job functions, for example:

Facilities Management will be able to plan Heating, Ventilation and Air Conditioning (HVAC) requirements, as well as power and floor space needed to support equipment listed in Asset Repository for a specific location. To also perform the functions needed to adhere to legal, environmental, business, and regulatory requirements associated with equipment redeployment and termination.

Financial Services will be able to budget for asset procurement, depreciate assets over time, and complete tax documents. A report of equipment and their resale value can be used to aid in planning equipment upgrades and to reduce the “Total Cost of Ownership” associated with equipment.

Contracts Management will be able to negotiate vendor discounts and enterprise agreements. Additional vendor agreements may be required to support transportation and warehousing, equipment service and reconfiguration requirements, data wipe services and products, buyers, and scrap dealers.

Contingency Planning personnel will be able to develop recovery plans for mainframe and office assets contained within the Inventory System, based on the assets relative importance (as stated within the Criticality field). Surplus equipment may be utilized to support recovery operations, if needed.

Technical personnel will be able to resolve problems more quickly with the information contained within the Inventory System, because they will have a listing of the assets contained within a location.

The Inventory System should be integrated within the everyday functions performed by personnel associated with entering and maintaining asset information. The system will reduce the effort devoted to asset management, while supplying many personnel with the information they need to perform their functional responsibilities.

1.1.4. Objectives

The objective of Inventory Management is to manage the physical and logical properties of I/S resources and their relationship, while ensuring that service level commitments are achieved. This process will:

Ensure efficient and timely identification of vital corporate assets.

Assist in managing the enterprise-wide inventory.

Provide a common repository for asset protection.

Plan and control the proliferation of assets across the enterprise.

The objectives of Inventory Management are:

To identify and track all data processing assets in an Inventory System Repository.

To define the process by which assets are identified and maintained in the Inventory System.

To provide Inventory System access to all necessary personnel (data entry, update and deletion).

To provide a full range of reports that will satisfy informational requirements.

To document the Inventory Management System within the Standards and Procedures Manual.

To provide training to personnel responsible for supporting the Inventory Management System.

1.1.5. Functional Areas.

The functional areas that interface with an Inventory Management System are:

Figure 2: Overview of Inventory Management functional areas.

All of the functional areas listed above can utilize the information contained within the Inventory Management System's Central Asset Repository of information. Additionally, the Recovery Management area could utilize inventory information to identify an assets criticality (especially when the asset's location and owner are identified within the Inventory Management System). Through the use of reports generated from the Inventory Management System's Repository, it would be possible to obtain a listing of all "Most Critical" resources, by location and group. This report would then serve as the basis of a Business Recovery Plan.

1.1.6. Integrated Inventory Management System

To successfully implement an Inventory Management System, it is necessary to integrate it within the everyday functions performed by company personnel. That is, when a user wants to order equipment or software, they would call up the Inventory Management System screen associated with Acquisition. The same types of processes should be available for Redeployment and Termination of assets. Should a user request the acquisition of a specific type of asset, then it could be possible for the inventory system to determine if the asset is already in surplus, or if it should be purchased under an existing Volume Purchase Agreement with a vendor.

Figure 3: Overview of an integrated Inventory Management System.

The utilization of Inventory Management Systems to control the purchase and installation of assets can aid in the control of the business environment, while assisting in the assignment of personnel to perform asset related work functions. This methodology will result in a work-flow and asset management system.

1.1.7. SMC Discipline Interfaces

The Systems Management and Controls disciplines that will interface with the Inventory Management System are illustrated within the diagram listed below.

Figure 4: SMC Discipline Interfaces .

The disciplines interfacing directly with Inventory Management and their functional responsibilities are:

Capacity Management (i.e., PC memory and speed, DASD size, etc.).

Performance Management (speed and usage information).

Change Management (version and release information, benchmark, testing, etc.).

Recovery Management (recovery planning for critical assets and sizing requirements for recovery facilities).

Service Level Management (Service Level Definitions - SLD's and Service Level Reporting - SLR of user processing and service requirements).

Problem Management (troubleshooting, pathway, version and release information, etc.).

Configuration Management (hardware, software, location, HVAC requirements, power, water, floor space, etc.).

1.1.8. Inventory Management disciplines and interfaces

The Inventory Management function is responsible for tracking all assets, from Mainframe based to Data Network based, that are connected to the data center or data network. In each case, the Inventory Management Systems must be able to:

Identify the asset and its serial number;

Associate the asset with its owner and location;

Relate the asset to its vendor; and

Track the maintenance level of the asset.

The ideal Inventory Management System should also:

Provide financial information related to an asset;

Define the criticality of the asset; and

Supply history information for the asset.

The Inventory Management System interfaces with the following departments:

Finance;

Contracts;

Systems Software;

Production Services; and

Facilities Management.

1.2. Process Description

The process of Inventory Management receives input from Systems Management Controls (SMC) disciplines and other functions within the I/S organization as well as other areas throughout the enterprise.

The vehicle used to control the Inventory Management discipline is Change Management. Without adequate Change Management the integrity of an Inventory Management process cannot be ensured. These SMC disciplines and functions encompass both system and data network elements and feed the Configuration Management discipline.

Inventory Management inputs can come from either the Network or System area and can include a variety of input methods:

1.2.1. Network

The Network area must account for new acquisitions installed into the configuration. Because the complexity of today’s networks makes tracking new acquisitions difficult, it is advisable that tracking be accomplished through the use of discovery type applications which monitor and interrogate asset changes automatically. This type of tracking would capture vital product data (VPD), or perform product identification which is generally imbedded on PC-type products by the manufacturer.

1.2.2. System

Within the system area changes to the physical environment are systematically reported through the integrated change process. This discipline incorporates all hardware and software reconfigurations or updates. All inputs to the centralized data base will be subject to the change process.

The following page contains an overview of the Inventory Management process.

1.2.3. Inventory Management Process

Figure 5: Inventory Management System - Overview of Process

The above provides an Overview Diagram of the Inventory Management process, while the following illustration provides a Flow Diagram of the Inventory Process.

1.2.4. Inventory Management Flow

Figure 6: Inventory System Flow Diagram

1.3. Process Flow.

The process is entered as a Controlled or Non-Controlled Asset Change Request (ACR) as follows:

1.3.1. 1. Non-Controlled ACR Entry:

ACR received by any method other than the Change Control process.

- Confirm all necessary information is available about the asset.

- Request is reviewed locally for acceptance.

- Problems documented and returned for resolution.

- ACR accepted and authorized.

- Request forwarded to Change Control process for input as a Controlled

ACR.

1.3.2. 2. Controlled ACR Entry:

Validate all data elements are present in the Change Record.

Review by all I/S organizations accountable for asset control.

Problems documented and returned for resolution.

ACR accepted and authorized.

Update Inventory Repository data base.

Create data center record associated with the asset.

Create system record associated with the asset.

Create component record associated with the asset.

Create feature records associated with the asset.

Generate physical configuration reports and distribute.

Create financial records if appropriate.

Generate financial reports if appropriate.

Generate physical inventory reports and distribute.

Close the change record.

1.3.3. Implementation of Inventory Management

Efficient processing and operations management start with an integrated approach that links all facets of system management together. Inventory Management is just one of the disciplines. Each augments the other, and provides the ability to effectively manage a large systems environment.

Accurate inventory data is vital. A lack of such data affects the other Systems Management disciplines ability to function. The automated element of inventory management monitors the enterprise-wide data network processing environment for change, while the system environment relies on the change process (which may or may not be fully automated) for accurate input.

The products and tools that comprise the Inventory Management System use data network definition information, Vital Product Data, local configuration definitions and in some cases, discovery applications to arrive at inventory information.

This process must embrace the following areas to be effective:

1.3.4. System Environment

Today the system programmer can define hardware configurations for multiple MVS/ESA operating systems through Hardware Configuration Definition (HCD). HCD reduces complexity and shortens the time required to successfully define an I/O configuration by providing a panel-driven interface, panel defaults, and data entry validity checking.

Dynamic reconfiguration management allows the support organization to implement system configuration changes without interrupting system service. System availability is increased by eliminating the need for an IPL to change the hardware configuration, or to change the software definition for devices, control units, and channel paths. This ability to dynamically reconfigure works in conjunction with HCD and allows the new system configuration to be implemented without interruption.

Enterprise Systems Connection (ESCON) Manager enhances user control and manageability in an ESCON architecture environment when changing ESCON Director (ESCD) configurations. The changes are entered at a host processor rather than at the local ESCD consoles in the mainframe environment.

HCD and ECSON are highly dynamic tools that can effect configuration changes easily and swiftly. However, there are no automation techniques currently in use which update the inventory data base. Updates to the inventory data base require manual intervention, therefore, it is important that these interfaces to HCD and ESCON be constantly monitored and proper change control exercised to maintain asset integrity.

1.3.5. Network Environment

The complexity of the network environment requires an integrated set of facilities to store and display network configuration data for all network resources. This includes OSI, TCP/IP, SNA, Ethernet, and any other network resources. These facilities are tailored for network operational use and contain information that is pertinent to hardware and software inventories (e.g., Vital Product Information).

When dealing with large networks the immediate problems associated with the collection of asset information is enormous and therefore, subject to significant errors. If the configurations are too complex, they become impossible to manage or understand. The typical network is composed of many nodes extending to many different topologies. The technique commonly used to manage networks is to break up the larger networks into smaller, manageable units. Once the management of these clusters is underway, you can proceed to manage several clusters from a higher node in the configuration hierarchy. This allows for greater control and accuracy.

On the other hand, if the configurations are too granular, the system can become a collection of small configurations with no relationships established between each other. For example, when defining a large 3745 network, we first define the lines, along with their drops, as separate configurations, then connect these lines to the 3745 in another configuration. This logic can be applied to other layouts as well, including the client/server arena.

Although the industry direction is to automate network asset control as much as possible, managing the entire configuration does not necessarily have to be automated from the start; especially within the enterprise. It is our primary purpose to reduce the amount of manual work and the possible human errors typically found in current network configuration and asset management processes. Therefore, the technique presented here does not provide the Company with the complete automation process for the entire enterprise configuration. Rather, we recommend that you begin the initial steps for replacing much of the tedious work of entering and updating configuration data manually.

1.3.6. Data Requirements for Inventory Management

To ensure a consistent, centralized and integrated control, as described in the previous section, a common data model must be built. This will ensure a consistent reporting process to the inventory data base regardless of where the data is stored.

In the event of incomplete record information, the inventory management area must re-solicit, or advise the responsible asset area of the missing data elements. This reentrant approach provides a disciplined strategy to build a reliable inventory.

The structure illustrated in the next diagram allows the description of hierarchical relationships among data centers, systems, components, service organizations, and financial data. By entering descriptions of the hardware and software system components, along with information about their status and support data, a data base can be built which supports parent/child relationships.

The figure on the next page shows the interrelationship between component records:

1.3.7. Inventory Management Data Model

Figure 7: Inventory Management Data Model

The following items are required from asset sources to support an integrated Configuration Management approach.

1. Data Center Record.

This record contains on-line information about the data processing centers, the system name, location codes, emergency phone numbers, managers, and contact names. The software and hardware components, and system records will refer to this record.

2. System Record

This record contains information relative to each processing system within the processing center. This record should contain the system names by LPAR, location codes, operator names, support numbers. Software and hardware components can refer to this record.

3. Service Record

This record contains the service organization’s data. Maintaining service organization records is advantageous when a user is displaying a record of a failing component. This record should contain the name, location, prime-shift phone number, off-shift phone number, hardware and software representative’s name, and contact phone numbers, and a description of the service organization. Hardware and software components can refer to this record.

4. Financial Record

Helpful information in this record assists in warranty and service incidents. Hardware financial records contain a user financial id, a financial type, and a description. For software records the same information is required in addition to a license type record entry.

5. Hardware Components

For hardware component records a consensus must be reached on the hardware types to be managed. A hardware model record for each hardware type will be created and all common hardware components will be entered using this template. This record should contain the following information:

Component ID,

Product Number

Serial Number,

Generic device type,

Model,

Manufacturer,

Owner,

Install Date,

Location,

Maintenance Vendor,

Contract type,

Component status,

Component Criticality

Component description.

In some instances a hardware subcomponent record must be entered. A subcomponent can be thought of as a feature that can be a stand-alone component and has mobility in the inventory (for example, 3726, 3727, external hard disks). This will allow subcomponents to be removed or moved from their hardware component or attached to another component. This record should contain a subcomponent status code and a description.

6. Software Components

For software component records a consensus must be reached as to what level of installed software will be within the scope of the asset data base. For example, is the workstation (PC-based) software to be managed? If so, are we to account for all application software or just operating system software?

The answers to these questions are linked to what kind of information the user support groups require to provide service to the client. In a centralized Help Desk environment, all user application software, including maintenance levels, are maintained. This provides up-to-date information to the Help Desk personnel about the user environment and adds greatly to their productivity.

A software model record for each component contains an ID, maintenance level, program type, status and a description. A typical software record should contain the following information:

System (application runs on),

Product Number

Name,

Model,

Vendor,

Serial Number,

Renewal Date,

License Type,

Contract Type,

Maintenance Level,

Description.

7. Feature Components Record

This record identifies associated features and relates these features back to other records.

8. Model Component Record

The industry uses this type record as a productivity tool to greatly enhance the ability to build large data bases quickly with minimum data entry errors.

Model records themselves do not hold configuration data, but they make the entry of data easier by allowing the creation of component records from models that hold information common to a number of components (or subcomponents) of the same type.

The model capability also provides the ability to build one or many relationships between model features and hardware or software components. Features that are common to many components can be contained in a single model feature record that is referred to by many component records.

1.3.8. Collecting, Monitoring and Reporting Data

1. Monitoring and Reporting Data

Once the inventory data base has been built it will be used to satisfy the following requirements

Determine bypass and recovery procedures when a failing component has been identified.

Determine the level of a component, and also other components that are affected when a problem occurs.

Establish relationships between a component and any problem or change record in the data base.

Search for any components meeting specific characteristics, such as all terminals in a network and the locations to which they are assigned.

Generate reports on specific configuration information, including but not limited to the following:

- Hardware or software components with related features,

- Physical inventory by location,

- Hardware and software configuration maps, and

- Service reporting for maintenance contracts, warranty, and invoice

tracking.

2. Collecting Data

The Record Hierarchy in the following diagram indicates that component records refer t data center, system, service, and financial records. These four records are informational components. This means they must be created prior to creating the component records (hardware, software). It saves time because these records must be defined before they can be referenced in component records. This allows you to establish connections as you create the records.

1.3.9. Inventory Management Record Hierarchy

Figure 8: Inventory Management Record Hierarchy

1.4. Discipline Relationships

To ensure the integrity of the process, Inventory Management must interface with multiple business and I/S system management functions. The interface to these functions provides the foundation for strong Inventory Management practices.

1.4.1. Business Function Interfaces

Some of the more common business functions that interface with Inventory Management include:

Purchasing

This resource manages all information systems requirement identification through the procurement process. Inventory Management provides input to Purchasing in terms of system and network standard asset information.

Accounts Receivable / Payable Department

This function collects usage data and bills information System (I/S) expenses to the appropriate users. It supports accounting, budget planning, tracking of project costs, and other activities. Inventory Management provides financial records as input to the Accounts Receivable / Payable process and vice versa. This two-way interface occurs with the approval and submittal of billings for payment.

I/S Management Committees

These groups investigate tools and services to provide policy information and translate that data into recommendations for I/S productivity improvements and services. Inventory Management will provide input to these groups in terms of product standards and technology strategies.

Strategic Planning Committees

These groups deal with long-range planning and the integration of I/S objectives with the business objectives of the enterprise. Inventory Management provides an interface to Strategic Planning by providing insight into device migration patterns, trends, and direction, and the Strategic Planning Committees provide information back to the disciplines as well.

Security Department

This function manages the registration or enrollment of people and programs to access controlled I/S resources. Inventory Management provides input about device configurations and security interfaces to this functional area.

User Support Groups

Since these groups are responsible for their equipment acquisition, they must be compliant with the inventory process. Tracking the acquisition of network and computer equipment at the local level can be difficult without their full participation. To ensure accountability of such purchases, provisions should be made for a periodic physical inventory of such groups to ensure a level of inventory integrity.

Client Support Services

These groups define the services that will be needed to support the I/S clients within the enterprise. Within Services Management are two key areas:

1. Help Desk - This area provides a single point of contact for clients to request services and obtain resolutions for problems.

2. Service Level Planning - this area identifies the agreement between the I/S organization ad the user community that defines the level of service. The service level agreement is also used to define policies for operations and performance management.

1.4.2. System Management Interfaces

The Inventory Management discipline is dependent upon various disciplines and functions within the enterprise in achieving its objectives. These disciplines and functions and the assumptions related to their tasks are listed below:

Change Management

Coordinates the various tasks performed in configuration change and testing across the data processing environment. Any changes to the I/S environment that affect Inventory Management are input from this discipline.

Problem Management

Assists the I/S organization in locating, identifying, and resolving inventory problems. The Problem Management discipline will provide input to Inventory Management as problems arise that require changes to resolve conflicts.

Facilities Planning

Required to participate in the Problem or Change process as they pertain to the physical environment and is accountable for any actions required to comply with the inventory management process. It is essential that this group provide input to Inventory Management and vice versa, to ensure changes in physical asset configurations are noted.

1.5. Inventory Management Tools

Inventory Management uses network definition information, Vital Product Data (VPD), local configuration data bases and, in some cases, discovery applications in order to arrive at inventory information.

The following list of Inventory Management tools was accumulated after conducting a general survey of large corporations in the area. The participants represented large corporations with an annual I/S budget of over $100M. The survey solicited information about how they performed Problem, Change, and Inventory Management and what techniques and tools were used to accomplish tasks in the two areas that follow.

Those products which are specifically mentioned were approved by the vast majority of participants. We also list major Inventory Management functions that can be fulfilled by any number of products, but do not specifically mention a product by name.

1.5.1. Asset Management at the System to Server Level

The major components that provide the collection and reporting vehicles for Inventory Management from the system level out to the network server level include:

VTAM and NetView

VTAM and some specialized features of NetView are responsible for maintaining the necessary linkages to the physical asset, whether it is within the system complex or out to the server level on the network.

Centralized Data Bases

All assets and their associated information are stored in a centralized data base. Editing and browsing capability are available through an on-line menu driven, front-end that provides restricted security access, if necessary. This security is provided through any number of host-based security packages.

Network Configuration Application (NCA) / MVS

NCA/MVS is a useful tool for migrating existing stand-alone (PC-based) inventory control data bases to host-based formats. It should be noted that in some cases conversion utilities have been written to convert these stand-alone environments into a data base file structure.

Enterprise Physical Connection Tool (EPCT)

EPCT is a useful product for building configuration data bases and producing physical and logical diagrams. The figure below illustrates the usage of these tools within the process.

Figure 9: Asset Management at the System to Server Level

1.5.2. Industry Standards

Centralized Inventory Data Base Repository

The industry uses any number of system management products which integrate the entry of Problem, Change, and Inventory Management into a common, centralized data base repository. However, these integrated products must interface to the tools listed below to facilitate the automation ad centralization of an asset management data base repository.

This product can be ordered as an PRPQ through the IBM Corporation.

1.5.3. Downstream Network Server Configuration and Inventory Management

The following figure illustrates a downstream view of Network Configuration and Inventory Management.

Figure 10: Downstream Network Server and Inventory Management

Asset management below the server level has not been widely implemented throughout the industry today. WAN environments have their own unique challenges. Most host-based products require an additional layer to bridge beyond the server level. The products listed below are seeing some industry penetration and promise to be viable tools in the coming months ahead.

1.6. Roles and Responsibilities

1.6.1. Inventory Manager

Responsible for maintaining the Inventory in a current and accurate state. Role is responsible for both mainframe and network resident devices and software components. Interfaces with Systems Management disciplines and Financial department.

1.6.2. Inventory Clerks

Responsible for maintaining the Inventory Data Base Repository and for guarantying the information contained within the Repository is accurate and in a current state. Information is data entered, or entered via automated tools. If automated tools are used, then clerks must be knowledgeable in program products used as a tool.

1.7. Process Evaluation

1.7.1. Present System Weaknesses

There is presently no Centralized Repository for asset information, because Inventory Management is performed by many various groups (i.e., mainframe, communications, data network, etc.). A consolidation of these data bases into a centralized Inventory Repository should be planned.

When migrating to a centralized repository, automated tools and interfaces should be developed, so that any acquisition, redeployment, or termination of assets will have to accomplished through the automated system. This will reduce the effort presently performed by personnel and guaranty the accuracy of the Inventory repository.

1.7.2. Recommendations for Improvement

Create a Centralized Repository of Inventory information.

Utilize Automated Tools and Front-end to the Inventory Repository.

Integrate the Inventory Repository with the everyday asset functions performed by personnel, such as:

Asset Acquisition,

Asset Redeployment,

Asset Termination,

Lease and Contract Maintenance,
