CI is the work product that identifies the project
characteristics. Like requirements documents, analysis documents. Therefore, we cannot change it after base lining
without a level of approval throw change request. CMMI ref page 192 Ex: Products that are delivered to the customer, work
products that affect the production and planning. Alternatively, work product
shared for many groups. CI's sample
: PMP, requirements, code, documentation and models, etc. |

03-Baselining Procedure
Purpose
The purpose of this procedure is to produce
baselines from the identified CI's. The procedure, when performed, ensures the
existence and existence’s announcement of the baselines that will be
considered as a starting point for further development phases in the product
development life cycle. The quality of the baseline is completely dependent on
the functional and physical audits done before the baselining.

Conduct functional audits to find the integrity between the plans,

plan. You can assure it by the following points: ·
Make sure all CI's are consistent by achieving the scope of the
requirements. ·
Review the source safe history and assure
that the related work products are affected only by CR by showing the
difference between the new version and the old one from version history. ·
For document and excel sheets, use the compare
and merge facility to assure that changes is only related to the CR. ·
For releases: Assure that major defects
are solved successfully. |

04-Change Control Procedure
Purpose
The purpose of this procedure is to guide
the performance of saving changes to any stable work product. The change
control procedure starts by raising a change request, and then being evaluated,
implemented and verified. The impact of these changes should be estimated and
then evaluated at the end of the project at the project closure phase.
