Solution

(i) Project Management

Planning, scheduling, budgeting, risk, resource, quality and stakeholder management. Tools: WBS, Gantt, PERT, CPM. Goal deliver on time/budget.

(ii) Test Case Design

Technique to create effective test inputs. White-box: Basis path, loop testing. Black-box: Equivalence Partitioning, BVA, Cause-Effect graph. Good test = high probability of finding error, non-redundant, best-of-breed.

(iii) Software Reliability

Probability of failure-free operation for specified time in specified environment. Metrics:

• MTTF (Mean Time To Failure)
• MTTR (Mean Time To Repair)
• MTBF = MTTF + MTTR
• ROCOF (Rate of Occurrence of Failures)
• Availability = MTTF/(MTTF+MTTR)
  Models: Musa, Jelinski-Moranda. Improves via fault removal, fault tolerance, testing.
