Two Marks with Answers
UNIT I- FUNDAMENTALS OF SOFTWARE QUALITY ASSURANCE
1) Write the statement of key management axiom.
A key management of axiom says that “what is not tracked is not done”
2) What is the prime benefit of an SQA program?
The prime benefit of an SQA program is ASSURANCE it provides management that the
officially established process is actually being implemented.
3) What are the goals of SQA?
a) To improve software quality by appropriately monitoring both the s/w and the
development process that produces it.
b) To ensure full compliance with the established standards and procedures for the software
process
c) To ensure that any inadequacies in the product, the process or the standards are brought
to management attention so that inadequacies can be fixed.
4) Write the responsibilities of SQA?
a) Review all development and quality plans for completeness
b) Participate as inspection moderators in design and code inspections

g) Implement the SQA plan
h) Evaluate the SQA program.
6) Write the reason for software quality assurance organization fail to have much impact
on software quality.
a) SQA organizations are rarely staffed with sufficiently experienced or knowledgeable
people

b) The SQA management team is often not capable of negotiating with development
c) Senior management often backs development over SQA on a large percentage of issues
d) Software development groups rarely produce verifiable quality plans.
7) Write short notes on SQAP.
“Software Quality Assurance Plan” that specifies its goal, the SQA tasks to be
performed, the standards against which development work is to be measured and the procedure
are organizational structure.
8) What are the points to be considered when SQA can be effective, while considering SQA
people?
a) The practice of starting new hires in SQA is a partial solution that can be effective only if
there are enough experienced people there already
b) Rotation schemes can also be effective from SQA.
c) New development managers be performed SQA
d) SQA to be effective, they must have good people and full management backing.

recommendation SQA will be ineffective.
12) What is the simple rule on SQA Reporting?
The one simple rule on SQA reporting is that it not be under the software development
manager. Project schedules are always tight, so these line managers are not likely to listen

sympathetically to reports of inadequate test plans, human factors problem or documentation
errors.

UNIT II - MANAGING SOFTWARE QUALITY
1) What are the basic principles of Project Management?
 Each project has a plan that is based on a hierarchy of commitments.
 A management system resolves the natural conflicts between the projects and between
the line of staff organization.
 An oversight and review system audits & tracks progress against the plans.
2) List at least four elements of an effective commitment?
a) The person making the commitment does so willingly.
b) There is agreement between the parties on what is to be done, by whom & when.
c) The commitment is openly & publicly started.

Contention system is that the best decisions are based on a full understanding of the relevant
issues.
To encourage the open expression of differences and their rational resolution.

It provides a forum for residing conflicts & monitoring progress against period and
product objectives. The topics should typically include an assessment of project performance
against plan & the organization performance against its goal.

5) Mention any four principles of phase reviews.
a) Before initiation & at predetermined points during the project. Detailed technical &
management reviews are conducted.
b) The reviews are conducted by the project manager.
c) All involved line and staff organization participate.
d) The meeting is not resolving issues but to identify them & assign resolution
responsibility.
6) What are the four basic quality principles?
a) Unless you establish aggressive quality goals, nothing will change.
b) If these goals are not numerical, the 6.5 quality program will remain just task.
c) Without quality plans, only you are committed to quality.
d) Quality plans are just paper unless you track & reviews them.
7) Write short notes on Error Seeding.
Error seeding is a potentially intersecting way to evaluate program quality. The idea is
to inject a known number of “dummy” defects into the program & then to track how many of
them are found by the various tests or inspections.
8) Define availability.
The system ability to perform the intended function whenever needed, this is called
availability.
Availability= (1-MTTR/MTTR+MTBF) X100
MTBF: Mean time between failures
MTTR: Mean time required to response
Availability is the perfect of total time that the system is available for use.
9) Write short notes on Removal Efficiency.
It indicates the cumulative percent of the previously injected errors that have been
removed by the end of each project phase since defect removal costs can be expected to roughly
double with each project phase, attention should be focused on early removal.
10) List at least two critical elements of Software Quality Management system?
a) A responsible authority is named to own the quality data and the tracking and reporting
system.
b) Quality performance is tracked and reported to this authority, during both development
and maintenance.
c) Resources are established for validating the reported data and retaining it in the process
database.

11) What are the principles of the Contention System?
a) All major decisions are reviewed with the involved parties in advance, and the parties are
requested to agree. Where possible, any issues are resolved before proceeding.
b) When the time comes for the decision, all dementing parties are present and asked to state
their views.
c) When there is no disagreement, the senior manager determines if there is knowledgeable
agreement.
If any disagreeing parties are absent or if more preparation is needed. In later two cases, the
decision is defined until the necessary homework has been done.
12) What are the principles of Software Defect Prevention?
a) The programmers must evaluate their own process
b) Feedback is an essential part of defect prevention
c) There is no single cure-all that will solve all the problems
d) Process improvement must be an integral part of the process
