Introduction 

 

Program comprehension plays a major role in any non-trivial software development effort

 

• Two basic program comprehension approaches
  • Prevenient
    • The program understanding is written as a forethought before, during, or after the development of the source program

  • Posterior
    • The program understanding is extracted from the source program by means of special reverse engineering tools

 

The prevenient approach to program comprehension is hypothesized to be a very good investment seen in relation to the total life time costs
