Change Management

To ensure all changes are assessed, approved, implemented and reviewed in a

Standardization of change procedure

controlled manner.

Increase efficiency in change implementation

Minimize impact

- Impact occurring as a result of release (Change Implementation)

- Current performance (Incident occasioning change)

Change Management

Scope

- Hardware- Communications equipment and software

-

- All documentation and procedures associated with the running, support and

maintenance of live systems.

- System Documents - Procedural Documents

- Recovery Plan - Role Alignment

- Code Export andDocumentation

- Process Documentation

- Architectural Documents - Test Scripts

Asset Management

A subset of ITILs configuration management that enhances the information collected

Gaining full control of organizations inventory

regarding system components

Managing ownership through the lifecycle of assets

Enables deeper analysis of component impact

Facilitate resource allocation and utilization

Manage costs associated with maintenance, licensing, andupgrades

Management in Parallel

Dependencies from Change Management

- Cost Analysis of Change Orders (Impact)- Cost associated with contract renewal

-

- Measuring the value of the service associated with the change

- Measuring the costs of Assets supporting the service

Dependencies from Asset Management

- Maintaining Asset Lifecycle status

The Gap

If Change management aligns the decisions and their efficientimplementation, then it can be argued that Asset management isthe element that is leveraged to determine why a the decision isviable.

- While cost of an individual item is valuable information, how can an asset systemalone account for components that arent inherently related to a product?

- Can impact truly be minimized simply by accounting for the cost associated with

- Will understanding the status of all assets in an organization truly allow for effectiveutilization of those assets going forward?

- Establishing and Maintaining system performance

- Control the details of components relevant to services with in an organization

CMDB

As a normalized point of reference:

- Consumes discovered system details- Ensures data integrity by:

-

- Combining data into a single, accurate, entry

- Provides an access method for federated sources-


11/25

Individual Structures

Change Management:

- Capable of aligning controlled processes that add, remove, or manipulateservices and there components with in an organization

- Maintains accurate data regarding the configurations supporting services

within an organization

Asset Management:

- Managing components and there underlying contracts through their lifecycleand ensuring effective utilization.

Full Service: Order Fulfillment

Aligns with traditional concepts of CMDB

Discovered components

Related and exist as part of a service

Value of Configuration Awareness

Service Continuity

- Ensuring service recovery

- Risk Reduction

erv ce va a ty

- Maintenance of components

- Serviceability from external suppliers

- Knowing not only direct relationship, but underlying dependencies that supportservices as well

Before an organization can properly enable continuity and availability for itsservices, the CMDB will need to be aligned with those services accordingly

How Impact Simulation Enhances Change

Applies relationships mapped in the CMDB to the Change Request

Allows for the Impact and Urgency of a ticket to be updated toreflect the combined level from the simulation

Impact simulations can be stored in Work Info for tickets


24/25

Software License Management

As a consumer of discovery sources the CMDB is aware ofsoftware present with in the organization.

Combined with the CMDB Product Catalog it is possible to, .

Asset management allows for license compliance to be automated

- Applying software certificates that are applied to configuration items

- Account for each consumed certificate

- Normalizing data from all discovery sources to ensure accurate licenseconsumption.
