Ans : The following are the similarities and the differences between the Cleanroom software engineering development and OO software engineering paradigm.
Similarities
Lifecycle – both rely on incremental development
Usage – cleanroom usage model similar to OO use case
State Machine Use – cleanroom state box and OO transition diagram
Reuse – explicit objective in both process models
Key Differences
Cleanroom relies on decomposition and OO relies on composition
Cleanroom relies on formal methods while OO allows informal use case definition and testing
OO inheritance hierarchy is a design resource whereas cleanroom usage hierarchy is system itself
OO practitioners prefer graphical representations while cleanroom practitioners prefer tabular representations
Tool support is good for most OO processes, but usually tool support is only found in cleanroom testing, not design.
