  2. Explaining the meaning of function-oriented metrics along with the five information domain value calculation methods
  3. Calculation of function points

Answer:A) The function-oriented metrics are indirect software metrics. Instead of thenumber of LOC, the emphasis is more on the functionality of the product.The function-oriented metrics were first proposed by Albrecht. He suggesteda productivity measurement approach known as the Function point method.In this method, function points are used. A function point is a relation that isbased on the countable measures of software information domain andassessment of software

6 Explain the code inspection technique. What are the different steps followed to conduct code inspection

Explain the code inspection technique

Steps followed to conduct code inspection


Answer: We can define “code inspection” as one of the techniques of formal method to review a software product. The goal of code inspection is to detect errors caused due to typological mistakes and incorrect programming. Code inspections are highly structured and require proper training for all individuals. This kind of review is different from other reviews, such as peer review
