Software quality assurance 2 UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Chapter 6 - Development and Quality plan - CORRECT ANSWER -
Objectives of having a development and quality plan - CORRECT ANSWER - recruit
team members, decide if waterfall or agile, resolve dev risks, milestones, sprint lengths, give
mgmt data for project control
Elements of plan for devs - CORRECT ANSWER - specify deliverables, define project
interfaces, methodolity and tools, milestones, map of dev process, cost estimate
element of plan for software quality - CORRECT ANSWER - list of quality goals, review
activities, software tests, accepptance tests for external software, procedures and dates for
versions
Classes of software dev risks - CORRECT ANSWER - scheduling/timing risks, system
functionality risks, subcontracting risks, requirement mgmt risk, resource usage and performance
risk, personnel mgmt risk. must prioritize risks!
boehm and ross's top 10 software risk items - CORRECT ANSWER - developing wrong
functions, unrealistic schedule and budget, wrong interface for user, gold plating, continuous
stream of req changes, personnel shortfalls
Chapter 7 - Intergrating quality activities in project lifecycle - CORRECT ANSWER -
factors that affect required intensity of sqa activities - CORRECT ANSWER - project
factors (technical complexity and difficulty, severity of failure outcomes, project magnitude),
team factors (professional qualification of team members, availability, experience, familiarity
(new team members)),
,verification process - CORRECT ANSWER - does the product satisfy conditions at the
start of the phase
validation process - CORRECT ANSWER - does product satisfy specified requirements
qualification process - CORRECT ANSWER - is system or component suitible for
operational use
model's quantitiative result for DRE - CORRECT ANSWER - measure total effectiveness
at removing defects, and the total costs to remove defects
Defect Removal Efficiency - CORRECT ANSWER - gives a measure of the development
team ability to remove defects prior to release. It is calculated as a ratio of defects resolved to
total number of defects found. It is typically measured prior and at the moment of release.
What is the inverted v diagram - CORRECT ANSWER - dev activity - requirements,
system/HLD, architecture design, module design
Coding
unit testing, integration testing, system testing, UAT
Calculating DRE V1 - steps - CORRECT ANSWER - assume 100% defects, get average
% of defects originating in each phase, calculate cost of each plan via matrix
Phases of software development RDU ID SO - CORRECT ANSWER - Requirmenents,
design, unit coding, integration, documentation, system testing,operation
Calculating DRE v2 - steps - CORRECT ANSWER - 1) take req% and place in ID box for
D_req.
ID * (1 - % of FE (given)) = PD.
, ID - PD = RD
sum to get totals per row
POD - CORRECT ANSWER - phase originated defect
PD - CORRECT ANSWER - passed defects
RD - CORRECT ANSWER - removed defects
FE - CORRECT ANSWER - filtering effectiveness
TRC - CORRECT ANSWER - total removal cost
RDRC - CORRECT ANSWER - cost of defect removal per phase. unit cost of removal
Chapter 8: reviews - CORRECT ANSWER -
formal design reviews - CORRECT ANSWER - leader, review team of project memebers,
customers, professionals outside project. YOu don't fix in design reviews. you sign off formally,
approve document, verify and validate comments, decide action items. approve, partial approve,
or denial of design review at end. DR report is summary of outcome
peer reviews - CORRECT ANSWER - both inspections and code walkthrough (formal and
less formal) review leader, author of review, and specialized professions. Feedback only, not
formal sign off
Chapter 9: software testing strategies - CORRECT ANSWER -
