Definition
“An aggregation of hardware, software, or both,
that is designated for configuration management
and treated as a single entity in the configuration
management process.”

Configuration items
Software configuration items are not only program code segments but all type of
documents according to development, e.g
 all type of code files
 drivers for tests
 analysis or design documents
 user or developer manuals
 system configurations (e.g. version of compiler used)

Configuration items
 In some systems, not only software but also hardware configuration exist! Eg.,
CPUs, bus speed frequencies

Finding Configuration items
 Large projects typically produce thousands of entities (files,documents, data ...)
which must be uniquely identified.
 Any entity managed in the software engineering process can potentially be brought
under configuration management control
 But not every entity needs to be under configuration management control all the time.

Finding Configuration items
 Some items must be maintained for the lifetime of the software. This includes also
the phase, when the software is no longer developed but still in use; perhaps by
industrial customers who are expecting proper support for lots of years.
 An entity naming scheme should be defined so that related documents have
related names.
 Very similar to object modeling
 Use techniques similar to object modeling for finding Cls!
 Find the CIs
 Find relationships between Cls
Cls is nothing but an class

Some configuration items are
 Requirements Analysis Document(RAD)
 System Design Document (SDD)
 Object Design Document (ODD)
 Unit tests
 Source code
 Input data and data bases
 Test data
 Support software (part of the product)
 Once the Configuration Items are selected, they are usually organized in a
tree
