Short Question’s
5: How Variation Control is the heart of Quality Control?

We can control the quality by minimizing the difference between the predicted
resources needed to complete a project and actual resources consumed/used
including Staff, equipment and time
6: Justify the Statement “The Race for Quality has no finish line, technically it’s more like a
death march”



Since the Quality of product is subjective(value to some one) no matter how much
objective quality exists if it is no value to user then you cannot achieve a quality
product.
Perfection cannot be achieved
100% testing is not possible since we don’t have enough time to test a product
exhaustively.

7: Is Low coupling supports modularity? Give the reason in any case

Yes Low coupling supports modularity because low coupling means less
dependency between modules. You can easily integrate new modules in system if
there is low coupling between modules and hence it supports modularity.
8: Apply GQM approach on the following goal, “To reduce the cost of maintenance as a
result of defects”. Now list at least two Questions and metrics each to satisfy this goal
The Questions:
1. What is the cost of maintenance per Quarter, over the past 2 years?
2. How many defects were detected per Quarter, and fixed per Quarter, over the past 2
years?
3. What % of these defects were due to new development, as opposed to old
development?
4. How much does it cost to find and fix a new defect (per severity)?
5. What efforts have been made to attempt to reduce defects?
6. What % of defects could have been detected in an eralier phase to that in which they
were detected?
7. What is the minimum ROI (return on investment) for reducing maintenance costs?
The Metrics and Measurements:
1.
2.
3.
4.
Number of defects detected, fixed, re-opened, etc. per Quarter
Average time taken to find, fix, retest (re-fix, re-retest !!), per severity
Cost of #2
List of efforts to reduce defects, and the results of these efforts
