3. So, Whats SCM Definition?
• Configuration Management tools are
used to strore versions of system
components, building systems from
components. And monitor the release
version of the system tot he customer
along with the report

4. SCM Puposes
1. Identify Change
2. Control Change
3. Ensure the change is properly
implemented
4. Report changes to all the people who
need to know

7. Baseline
Is a software configuration management concept that
helps us to control chages without seriously
distrubing changes that may be warranted, define
baseline as:
“A specification or product that has been formally
reviewed and agreed upon that there-after serves
as the basis for further development, and that can
be changed only through formal change control
procedures”
IEEE Std 729 Standard Glossary of Software Engineering Terminology

8. Baseline Purposes
• Creation of a baseline is usually a
milestone in the schelude
• Everyone uses the same current
baselines
• To change the baseline requires a
formal process

9. Audits
• Software configuration audit
complements the formal technical
review to assess the configuration of
an object to the characteristics that
are generally not considered during the
review
