  1. Software Quality Assurance (SQA) Monitor the methods and standards used during the software development and verify their correct usage. What is Quality? - some definitions are: • Client satisfaction • No-Defects • Fulfillment of all requirements

  2. Objectives of the SQA Improve software quality through monitoring the process and the product. Make sure the standards and procedures are followed correctly and completely. Make sure that when procedures and standards are not being followed, that this is known to Project Management, and corrections are made.

  3. 1. Purpose 2. Reference Documents 3. Administration 4. Documentation 5. Standards, Procedures and conventions 6. Revisions y Audits 7. Software Configuration Management 8. Report of problems and corrective actions taken 9. Tools, techniques and methods 10. Code control 11. Control of Media 12. Control of providers 13. Collection of records, maintenance and y retention SQA Plan

  4. Quality Models • CMM • ISO-9000 • SPICE

  5. All models Agree on: • Improvement has to be based on adjustments to the process and not on blaming people. • Improvement has to be measured and its implementation constantly checked. • Improvement requires constant investment, rewards and incentives. • Improvement is a contínuous process. • If the level insatisfaction is not high enough, then things will not change.

  6. Capability Maturity Model (CMM) Continuously improving process 5.Optimizing Predictable process 4.Managed Standard and consistent process 3.Defined Disciplined process 2.Repeatable Not repeatable process 1.Initial

  7. Key-aspects to improve the software Process Level 2: RequirementAdministration Project Planning Plan follow-up Quality Control Configuration Management Level 3: Emphasis on organization processes Definition of processes Training Program Integral Administration Coordination between Groups Peer Revisions Level 4: Analysis and measurement of processes Quality Administration Level 5: Defect Prevention Technological Innovation Administration of process changes

  8. ISO-9000 • ISO : International Organization for Standartization • Is a series of generic norms for the construction, operation and documentation of systems fro the administration of quality • The 9000 series was elaborated in 1977 and first published in 1987. • It contains 5 sets of norms: • ISO 9000 • ISO 9001 • ISO 9002 • ISO 9003 • ISO 9004

  9. The ISO-9000 Norms Guidelines for the selection and use of the ISO-9000 Norm series. ISO 9000 Model to assure the quality of project development, production, installation and technical assistance ISO9001 Model to assure quality of production and deployment ISO 9002 Model to guarantee quality in the inspection and final tests ISO 9003 ISO 9004 Guidelines for the quality administration

  10. Quality System • “It‘s the structure, the responsibilities, the procedures, the processes and the organization resources required to practice the administration of quality to comply with the objectives established in the Quality Policy.”(ISO 8402) • “It‘s a mechanism that coordinates and controls the activities necessary to obtain the required quality in a product or service. It includes every element of an organization that is involved directly or indirectly with the development of the product or service”. (TickIT)

  11. SPICE Software Process Improvement & Capability dEtermination • It is an ISO project to develop an international standard for the Evaluation of the Software Process. • Starts in 1993. 25 counties participate.

  12. Determination of Capabilities Improvement of the Process SPICE Model Process Is subject to Identifies changes to Identifies the appropriate of Process Evaluation Leads to Leads to Can originate
