b) What do you mean by phase containment of error? 

Answer 1

a)

b)

Phase containment of errors means detect and correct the errors within the phase where it's actually lives. That is a design error should be detected and corrected within the design phase itself rather than detecting it in the coding phase. To achieve phase containment of errors we have to take periodic reviews.
