Change ManagementWe can manage change Process – most organisations have

defined input – requirement defined deliverables – changed system Series of known steps to covert input to deliverables Appropriate levels of reviews, and tests

But what about those “items” we were changing? Do we know the impact of changing one or more items How do we build the new solution?

which versions of other (unchanged) items are needed? How do we put the new solution into the live environment

V01.00

Managing the “items”Configuration Management Defines the what

calls them Configuration Items Ensures correct labelling & versioning

Defines the relationships Logical hierarchical structure Manages concurrency, branching, merging.

Keeps them safe In a secure library

Protects the library integrity Authorised access Updated / replaced by certified CIs Audits the library and associated processes

V01.00

Managing the Implementation

Release Management Has own environment for testing the build process Only accepts certified items Knows the configuration of environments

(i.e. what did we put where?) Test and executes the implementation of new solutions

Configuration Items

Why are they important? cost money contain intellectual value may belong to a 3rd Party

Licenses?

If it breaks…………? potential loss of business capability demands maintenance

CIs are ASSETS
