PURPOSE
Configuration status accounting (CSA) is the process of creating
and organizing the knowledge base necessary for the
performance of configuration management
In addition to acilitating M! the purpose o SA is
to provide a highly reliable source o confgurationinormation to support all program or pro"ectactivities including program management
systems engineering
manufacturing
software development and maintenance
logistic support
modification
maintenance.

Configuration Status Report Include
A list of the configuration items that comprise a baseline
The date when each version of each configuration item was
baselined
A list of the specifications that describe each configurationitem
The history of baseline changes including rationales for
change
A list of open change reuests by configuration item !eficiencies identified by configuration audits
The status of works associated with approved change
reuests by C".

Four Principle
hange Re#uests A Change #euest (C#) is a general term for a reuest to
change an artifact or process. The general process associated
with C#s is described in Concepts$ Change #euest
%anagement. Categories Aging (Time &ased #eports)'ow long have Change #euests of the
various kinds been open *hat is the +lag time,, of when in the lifecycle
defects are found- versus when are they being fied
!istribution (Count &ased #eports)'ow many Change #euests are
there in the various categories by owner- priority or state of fi
Trend (Time and Count #elated #eports)'*hat is the cumulative number
of defects being found and fied over time *hat is the rate of defect
discovery and fi

Build Reports &uild #eports list all the files- their location- and
incorporated changes that make up a build for a specific
version of the software. &uild #eports can be maintained both at the system and
subsystem level$
%ersion &escriptions Similar to #elease /otes- 0ersion !escriptions describe
the details of a software release.
Audits There two kinds of audits that are covered in the
contet of Configuration %anagement
1$2hysical Configuration Audits
3$4unctional Configuration Audits.
