Introduction

Software Quality Assurance (SQA) as a ‘planned and systematic pattern of all actions necessary
to provide adequate confidence that the item or product conforms to established technical
requirements’. SQA does this by checking that:
 plans are defined according to standards;
 procedures are performed according to plans;

 products are implemented according to standards.
A procedure defines how an activity will be conducted. Procedures are defined in plans, such as
a Software Configuration Management Plan. A product is a deliverable to a customer. Software
products are code, user manuals and technical documents, such as an Architectural Design
Document. Examples of product standards are design and coding standards, and the standard
document templates.
