Pm 9 quality

  1. 1. Quality Management Getting it Right
  2. 2. Quality Management  It is not enough to make sure you get it done on time and under budget – but it has to be of good quality  Quality is a measure of how well your product does what you intend  How closely your product meets the requirements
  3. 3. Scope Time Cost
  4. 4. Product Quality Attributes • Reliability - The probability of failure-free system operation over a specified time in a given environment for a given purpose • Availability - The probability that a system, at a point in time, will be operational and able to deliver the requested services • Safety - The system’s ability to operate, normally or abnormally, without danger of causing human injury or death and without damage to the system’s environment • Security – The system’s ability to protect itself from accidental or deliberate external attack
  5. 5. Product Quality Attributes • Efficiency – Software should not make wasteful use of system resources (disk and memory space, CPU time, etc.) • Usability (ease of use) – Software must be usable by the users for which it was designed • Dependability (reliability, availability, security, safety,…) • Maintainability (ease of maintenance)
  6. 6. Quality Management Process  Quality Planning (Quality Management Plan)  Quality Control (Monitoring and Controlling)  Quality Assurance (Following Quality Standards)
  7. 7. Quality Management Plan Metric Goal Industry Std. How we will do it Schedule <5% <7% Use of skill Variance resources Defect Density 0 High Priority 0 High Strict quality 2 Medium 2 Medium measures 5 Low 4 Low Defect per module
  8. 8. Tools of Quality Control  Control Charts  Fishbone / Ishikawa diagrams  Pareto Charts  Flowcharts  Statistical Sampling
  9. 9. Control Charts  How effectively processes are controlled  How many items are above and below prescribed levels  What is acceptable limit and what action needs to be taken for items above UCL & LCL
  10. 10. Control Charts UCL LCL
  11. 11. Fishbone Diagram
  12. 12. The 8 Ms (used in manufacturing) •Machine (technology) •Method (process) •Material (Includes Raw Material, Consumables and Information.) •Man Power (physical work)/Mind Power (brain work): •Measurement (Inspection) •Mother Nature (Environment) •Management/Money Power •Maintenance
  13. 13. The 8 Ps (used in service industry) Product=Service Price Place Promotion/Entertainment People(key person) Process Physical Evidence Productivity & Quality The 4 Ss (used in service industry) Surroundings Suppliers Systems Skills

  15. 15. Quality Assurance deliverables Software development D1 D2 D3 D4 D5 process Quality management process Standards and Quality Quality review reports procedures plan
  16. 16. Development of process standards De velop Assess product Define process product quality No Yes Improve Quality Standar dize process OK process
  17. 17. ISO 9000 • International set of standards for quality management (ISO 9000:2000, ISO 9001:2000, ISO 9004:2000, etc.) • Applicable to a range of organisations from manufacturing to service industries • ISO 9004:2000 provides guidance for continual improvement of a quality management system to benefit all parties (employees, owners, suppliers, society in general,…)
  18. 18. ISO 9000 certification • Quality standards and procedures should be documented in an organisational quality manual • External body may certify that an organisation’s quality manual conforms to ISO 9000 standards (namely ISO 9001) • Customers are, increasingly, demanding that suppliers are ISO 9000 certified
  19. 19. ISO 9000 and quality management ISO 9000 quality models instantiated as documents Organization Organiza tion quality manual quality process is used to develop instantiated as Project 1 Project 2 Project 3 Project quality quality plan quality plan quality plan mana gement Supports
  20. 20. The Software Engineering Institute (SEI) Capability Maturity Model for Software (CMM) • judging the maturity of the software processes of an organization Level 5 Optimizing Le vel 4 Managed Level 3 Defined Le vel 2 Repeatable Level 1 Initial
  21. 21. Optimizing Process change management Technology change management Defect prevention Managed Software quality management Quantitative process management Defined Peer reviews Intergroup coordination Software product engineering Integrated software management Training programme Organization process definition Organization process focus Repeatable Software configuration management Software quality assurance Software subcontract management Software project tracking and oversight Software project planning Requirements management Initial
  22. 22. The CMM and ISO 9000 • There is a clear correlation between the key processes in the CMM and the quality management processes in ISO 9000 • The CMM is more detailed and prescriptive and includes a more detailed framework for improvement • Organisations rated as level 2 in the CMM are likely to be ISO 9000 compliant
