1. quality planning
2. Quality improvement
3. Quality contorl
Quality planning
1. Id the customer
2. determine the customer needs
3. understand those needs
4. Develop a product to meet needs
5. ensure product meets customer needs and organizations
Quality improvement
1. design a process that can produce the product
2. optimize process
Quality Control

2. operationzlize the process
Phillip Corsby (quality is Free
defined quality as conformance to requirements based on customers needs and advocated a top down approach to quality in hqihc its managements responsibility
Doing it right the first time
Central quality themes
1. customer
2. leadership
3. improvement
4. prevention is less expensive then inspection
CMMI
offer guidance on how an organiztion can best control its processes for developing and minting a project.
CMMI concepts
1. Process - set of activities used by people to maintain product associated with the project
2. Precess Capability - expected results that can be achieved by following particular processes
3. Process preformance- the actual results that are achieved by following a process
4. Process maturity - the extent to which a process is defined managed control and used
immature organizations
process are imporvised and developed ad hoc
Mature organizations
processes and roles are defined and communicatied throughout the organization
processes are consistent and improved continually
proactive and follow disciplined processes
CMMI maturity levels
1. Level 1: initial- general starting point - few processes are defined - processes are disciplined
2. Level 2:Repeatable: - processes are in place basics, schedules and budges are more realistic - process are standard and consistent
3. Level 3: Defined - Processes are predictable - documented throughout org, standard consitstne and stable
4. Level4: Managed - preoess are contuosuly improving
5 .Level 5: optimizing
Project Quality management plan
1. Quality philosphies and principles
2. Quality standards, processes and metrics
3. Quality assurance
4. Quality control
5. Learn, imporve and mature
Quality Philosophies and principles
1. Focus on Customer satisfaction
2. Prevention, Not inspection
3. Improve the process to improve the product
4. Quality is everyones responsibility
5 .Fact-Based Management
Cost of quality
sum of
1. prevention
2. inspection
3. internal failures
4. external failures
Quality Standards, processes and metrics
1. Standards - agreed upon specification to ensure all project deliverables meet intended purpose
2. Metrics - gauge quality by establishing tolerance limits and aiding defects - two parts the metric itself and acceptable value of the metric
defect
undesirable behavior associated with product or process
Metric categories
1. process- defects required to developed project deliverables - be controlled - focus on effectiveness of id and removing bugs
2. Product - satisfaction of customer - focus on customer satisfaction, performance and reliability
3. project - project meets its overall goal, scope schedule and budget to be managesd effectively
Quality assurance
provides an auditing of the poet to ensure standards process and metrics are defined and being followed
Verification
ocuses o the process related actives of the project to ensure that the product meets requirements
Verification types
1. Technical review - ensures product will conform to specified requirements - walk through and inspections
2. business reviews - ensure that the product provides the required fucnctianily in the scope
3. Management reviews - compares actual project against baseline project plan
walk through
process in which developer leads team through design
inspections
peer reviews
Validation
product oriented activity to determine if system meets customer expectations - occur towns the end of the project
Testing
provides a basis for ensuring that the product functions as intended and has capabilities defined in scope
Quality control
focuses on monitory actives as a result of the project to ensure project complies with standards
Common cause
variation due to people machines and environment that are normal interactions
assignable cost
variations create significant change in variation patterns changes in materials, poorly trained people and changes to work envolemnts
