This document discusses software quality assurance (SQA). SQA encompasses the entire software development lifecycle, including requirements, design, coding, reviews, integration, and testing. It aims to define and monitor the software engineering process. Benefits of SQA include ensuring development and maintenance follow plans, reviews and testing are conducted, and processes are redefined if needed. Effective SQA requires familiarity with development methodologies, quality standards like ISO 9001 and CMMI, and basic quality principles. An SQA plan outlines tasks, standards, reviews, audits, problem reporting and more. Quality processes involve inputs, outputs, and following a plan-do-check-act cycle. Common process frameworks are ISO 9001,

1. Software Quality
Assurance

2. Introduction
O Defining and monitoring the software engineering
process and methods used in delivery of products or
services
O It encompasses the entire software development life
cycle which includes process such as
 Requirements development
 Software design
 Coding
 Reviews and inspections
 Product integration
 Testing

3. Benefits of SQA
O SQA team should ensure that
 Software development and maintenance are followed
 Review, inspections and testing are conducted as
planned
 Compatibility of SQA plan and software development
plan
 Redefine the processes, if required
 Conduct internal audits

4. Who?
O Need to be familiar with software development and
engineering methodologies
O Have an understanding of ISO 9001:2008 , CMMI and other
client-specific process frameworks in addition to basic
principles of software quality
SQA Plan:
O SQA plan contains details of tasks to be performed
O IEEE Std 730-1998 is widely used.
O Purpose
O Reference Documents
O Standards, practices, conventions and metrics
O Reviews and audits
O Test
O Problem reporting and corrective action
O Records Collection, maintenance and retention

5. Process
O Set of practices performed to achieve given objective
O Inputs : information, materials, data etc.
O Output : information , data , product or service
Output
Skills
Procedure
Hardware
and
Software

6. O A process has mechanisms to control its behavior and
performance
Input Process Output Feedback
Resources

7. Process Frameworks
O The Plan-Do-Check Act(PDCA) cycle is the basic
philosophy followed in all quality standards
Plan
Do
Check
Act

8. Some process frameworks and quality standards
O ISO 9001
O SEI’s CMMI
O Six Sigma
O TMMi (Test Maturity Model Integration)
