The researcher paper observed software development project, which produced un-deterministic result of the project development. This paper aimed to find the relations of variable, which could contribute more knowledge for the successful completion and delivery of the project that increase the software process development delivery. However, the activity variables leads to determine the set of activities carried out the professional group and encourage them to provide more attention on the selective activities.
