The concept of a thing being understood is termed the target system and its mental representation is termed a mental model.

Program comprehension during software maintenance involves the acquisition of knowledge about programs, as well as accompanying documentation and operating procedures. The costs of performing program comprehension have been widely cited as being between 50-90% of overall cost of performing maintenance [Standish84], i.e. that much time is spent on understanding the code rather than just making [...]

Static slices depend on data flow control possibilities…. All the possible executions are captured and sometimes this is too much information, especially when debugging. Dynamic slices isolate all the statements that actually affect the value of a variable for a particular execution of a program. As well as looking at a variable at a particular [...]

Program Slicing is a software debugging technique used to isolate only those statements that are related to a particular statement under inspection. A Quick Example x = 42 d = 23 Suppose you were interested in the value of d. In this case we can see that x = 42 is not important or related [...]
