Systemic
1. There are many places where making the performance of the part worse will improve the performance of the whole.
2. Performance of a system depends on how the parts interact, never on how the parts act separately.
Proff. R. Ackhoff
Test Separa/on
Tes/ng should always be done by an outside party who is somewhat detached from the program and project.
System tes/ng should always be done by an
independent group such as a separate QA department.
