On his November 2007 paper Stop the Numbers Game, [5] he elaborates on several reasons on why the current number-based academic evaluation system used in many fields by universities all over the world (be it either oriented to the amount of publications or the amount of quotations each of those get) is flawed and, instead of contributing to scientific progress, it leads to knowledge stagnation.

David Lorge Parnas (born February 10, 1941) is a Canadian early pioneer of software engineering, who developed the concept of information hiding in modular programming, which is an important element of object-oriented programming today. The primary argument of Parnas’ paper, besides for modularization of systems, is that we must implement a concept called “Information Hiding” and the explanation of what that means. The topic of information hiding, which he first wrote about in 1972, was dominant within the course. The key idea is to design software modules around a single design decision that may change He is also noted for his advocacy of precise documentation.

However, in Parnas's seminal 1972 paper On the Criteria to Be Used in Decomposing Systems into Modules, this dictum is expressed in terms of information hiding, and the terms cohesion and coupling are not used.[1]. 1053{1058, 1972. Dr Parnas took a public stand against the US Strategic Defense Initiative (also known as "Star Wars") in the mid 1980s, arguing that it would be impossible to write an application of sufficient quality that it could be trusted to prevent a nuclear attack.
