3 Introduction The processes and dactivities t of the eperforming organization that determine quality policies, objectives and responsibilities to satisfy the project needs. Includes: Plan quality Perform quality assurance: auditing the quality requirements and the results from quality control measurements Perform quality control: the process of monitoring andrecording results Guide to PMBOK Mohammad A. Rajabi 3

4 Introduction Terminology: Quality: the degree to which a set of inherent characteristics fulfill requirements Grade: category assigned to the products. Same function, but different technical specifications Low quality, high grade or high quality, low grade Precision and accuracy The quality management approach here compatible with ISO Guide to PMBOK Mohammad A. Rajabi 4

5 Introduction Quality management complements project management. Both agrees in: Customer satisfaction: understanding, evaluating, defining and managing expectations of customers Prevention or inspection?: the quality is planned, designed, and built in, not inspected in! Cost of preventing over correcting? Continuous improvement: plan do check act cycle the basis for quality management. Organizational Project Management Maturity Model l(opm3) and Capability Maturity Model Integrated (CMMI) examples of process improvement models management responsibility Cost of Quality (COQ): total cost of efforts related to quality. Operational costs: product return, warranty claims, recall campaigns. Valuable investment! Guide to PMBOK Mohammad A. Rajabi 5

16 Tools and Techniques Benchmarking Comparing actual or planned project practices to best practices within or outside of organization, within same application area or another one Design of experiments (DOE) Statistical method for identifying influencing factors Should be used during the Plan Quality Process to determine the number and type of tests and their impacts on COQ Plays role in optimization of products and processes Can be used to reduce the sensitivity of products to variables Guide to PMBOK Mohammad A. Rajabi 16

17 Tools and Techniques Statistical sampling Involves choosing part of a population of interest for inspection Sample frequency and sizes should be determined during the plan quality process Flowcharting Showing the relationships among process steps Shows activities, decision points, and the order of processing Guide to PMBOK Mohammad A.

19 Tools and Techniques Quality management methodologies Six Sigma, Lean Six Sigma,,Quality Function Deployment, CMMI,... Additional quality planning tools Brainstorming Affinity diagrams (identifying logical groupings based on natural relationships) Force field analysis (diagrams of the forces for and against change) Nominal group techniques (brainstorming in small groups andreviewed by a larger group) Matrix diagrams (include 2,3, or 4 groups of information and show relationships between factors, causes, and objectives) Prioritization matrices (ranking diverse set of problems) Guide to PMBOK Mohammad A. Rajabi 19

20 Affinity Diagram Guide to PMBOK Mohammad A. Rajabi 20

21 Force Field Analysis Guide to PMBOK Mohammad A. Rajabi 21

22 Matrix Diagrams Correlation Mti Matrix Example = Strong relationship = Medium relationship = Weak relationship Actions Improve Improve Work Manufacturing Goals Environment Technology Cost Effectiveness Develop New Products High Quality Shareholder Value

23 Outputs Quality management plan Includes quality control, quality assurance, and continuous process improvement approaches for the project May be formal/informal, highly detailed or broadly framed Quality metrics What should be measured, how, its value and allowed variation Examples: on time performance, budget control, defect frequency, failure rate, availability, reliability, and test coverage Quality checklists Guide to PMBOK Mohammad A. Rajabi 23

24 Outputs Process improvement plan A subsidiary of the project management plan It details the steps for analysing processes to identify activities which enhance their value Area to consider include: Process boundaries: purpose, start, end, inputs, outputs, data, owner and the stakeholders of processes Process configuration: graphic description of processes, with interfaces identified ifi d and used to facilitate analysis Process metrics Targets for improved performance: guides the process improvement activities Project document updates Stakeholder register Responsibility assignment matrix Guide to PMBOK Mohammad A.
