What is recorded here?
Compared alternative decompositions of the same system and argued that modules should encapsulate design decisions likely to change rather than merely follow processing steps.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
This is the 1972 sole-authored paper’s modularization criterion, not a claim that Parnas alone invented every form of modular or object-oriented software design.
