(design reports, test docs, software manuals, installations plans) – Peer reviews. Inspection walkthroughs by colleagues. – Expert opinion: when in-house expertise are not sufficient.

The SQA system Infrastructure components for error prevention and improvements. Procedures and work instructions: – Quality assurance procedures: detailed definitions of specific type of software quality assurance activity. – Supporting quality devices: (templates and checklists) – these devises are gained by previous experience. – Saves time, contributes to new situations and improves communications. – Staff training, instruction and certification: – Training new employees, certifying staff after their knowledge.

The SQA system Management SQA components. – Project progress control: (resource usage, schedules, risk managements activities, the budget) – Software quality metrics: (Measurement of various aspects of software quality activities for process improvements. These are: – Quality of software and maintenance activities – Development teams’ productivity – Helpdesk and maintenance teams’ productivity – Software faults density – Schedule deviation. – Software quality costs: – Teams are encouraged who keep their quality costs low for higher quality. – Management allocates more funds on such teams for more profitable projects.

The SQA system SQA standard, system certification and assessment components. External tools and utilization of international professional knowledge. – Quality management standards: SEI CMM assessment standard ISO 9001 and ISO standards. – These standards focus on what is required and how to achieve it to the organization. – Project process standards: (International standards that provide guidelines how for team development and project process) IEEE 1012 standard ISO/IEC standard

There tasks include: – Preparation of annual quality programs – Consultation of in-house staff and outside expert on software quality issues – Conduct of internal quality assurance audits – Leadership of quality assurance of various committees – Support of existing quality assurance infrastructure.

The SQA system Organizing for SQA – the human components For SQA to apply the people of organization are most important. – SQA trustees, committees and forums: (These are the members of development and maintenance teams who have a special interest in software quality. Appointed for term or ad hoc service). – Continue.. Last part of the chapter for self reading.
