5. J.Nawrocki, Change Management Software Configuration Item (SCI) SCI = “Information that is created as part of the software engineering process.” [R.Pressman] Types of SCIs: computer programs (source code or exec) documents (also requirem. specification) data (e.g. test cases) if (a > b) a-= b;  18 27

6. J.Nawrocki, Change Management Baseline [IEEE 610-1990] A specification or product that has been formally reviewed and agreed upon, that thereafter serves as the basis for further development, and that can be changed only through formal change control procedures.

8. J.Nawrocki, Change Management SCCB Software Configuration Control Board (SCCB) Authorises: the establishment of software baselines, the identification of configuration items, the creation of products from the baseline library. Represents the interests of the project manager and all groups affected by changes to baselines. Reviews and authorises changes.
