3 Agenda Introduction Plan Quality Management Perform Quality Assurance Control Quality Sample Exam Questions 3

4 Introduction to Project Quality Management Experts define Quality based on: Conformance to requirements: Project s processes and products meet specifications. Fitness for use: A product can be used as it was intended. The concept addresses both: Management of the project Deliverables of the project Every project should have a Quality Management Plan. PMBOK 5E Ref #8.0 4

5 Quality vs. Grade Quality is the degree to which a set of inherent characteristics fulfill requirements. (PMBOK Guide 5th Edition definition glossary). It includes stated and implied needs. Grade is a category assigned to products or services having the same functional use but different technical characteristics. For example, a software product can be of: High Quality (no defects) and Low Grade (a limited number of features), or of Low Quality (many defects) and High Grade (numerous features) PMBOK 5E Ref #8.0 5

6 Accuracy vs. Precision Accuracy is an assessment of correctness. Accuracy means the measured value is very close to the true value. Precision is a measure of exactness. Precision means the values of repeated measurements are clustered and have little scatter. PMBOK 5E Ref #8.0 6

7 Project Quality Management The Project Manager and Project Team are responsible for managing the level of Quality and Grade The Project Team must determine appropriate levels of Accuracy and Precision PMBOK 5E Ref #8.0 7

8 Project Quality Management Modern quality management complements project management by recognizing the importance of: Customer Satisfaction: Understanding, evaluating, defining, and managing requirements to meet customer expectations. The product or service must satisfy real needs. Prevention over Inspection: Quality is planned, designed, and built into the deliverables not inspected in. The cost of preventing mistakes is generally much less than the cost of correcting them when they are found by inspection. PMBOK Ref #8.0 8

9 Project Quality Management cont d Management Responsibility: Management is responsible for providing the resources needed to succeed. Continuous Improvement: Initiatives such as the plan-docheck-act cycle as defined by Shewhart/Deming; quality initiatives such as TQM and Lean Six Sigma; process improvement models such as Malcolm Baldrige, Organizational Project Management Maturity Model (OPM3); and, Capability Maturity Model Integrated (CMMI). Cost of Quality (COQ): Total cost of conformance and nonconformance work. PMBOK 5E Ref #8.0 9

21 Seven Basic Quality (7QC) Tools PMBOK 5E Ref #Fig

22 Seven Basic Quality (7QC) Tools 1. Cause-and-Effect Diagrams Also known as: Fishbone or Ishikawa Diagram: Illustrates how various factors might be linked to potential problems or effects - helps to better understand a problem and the contributing factors Effective tool for studying processes and situations - leads to better understanding of a process by generating detailed questions about it 22

23 Seven Basic Quality (7QC) Tools 2. Flowcharts Also known as: process maps Shows activities, decision points and order of processing: Useful to understand and estimate cost of quality in a process Helps anticipate and analyze how, where and what problems may occur 23

24 Seven Basic Quality (7QC) Tools Flowcharts - SIPOC Model Flowcharts map operational details of procedures that exist within a horizontal value chain of a SIPOC Model PMBOK 5E Ref #Fig

25 Seven Basic Quality (7QC) Tools 3. Checksheets Also known as tally sheets used to: Organize facts to facilitate the effective collection of useful data about a potential quality problem Gather attribute data while performing inspections to identify defects PMBOK 5E Ref #

26 Seven Basic Quality (7QC) Tools 4. Pareto Diagrams Special form of vertical bar chart used to identify vital few sources responsible for causing most of a problem s effects Categories on horizontal axis are a valid probability distribution that accounts for 100% of possible observations Frequencies for each cause decrease in magnitude until other accounts for non-specified causes Typically organized into categories that measure frequencies or consequences PMBOK 5E Ref #

27 Seven Basic Quality (7QC) Tools Pareto Diagrams 27

28 Seven Basic Quality (7QC) Tools 5. Histograms Special form of bar chart Used to describe the central tendency, dispersion, and shape of a statistical distribution Does not consider the influence of time on the variation that exists within a distribution (unlike the control chart) PMBOK 5E Ref #

29 Seven Basic Quality (7QC) Tools Histograms 29

30 Seven Basic Quality (7QC) Tools 6. Control Charts Visually display if the process (measurements) are in control Help to predict trends Main use of control charts is to prevent defects, rather than to detect or reject them The upper control limit and lower control limit are generally +/- 3 sigma around a process mean set at 0 sigma Upper (maximum) and lower (minimum) values are based on contract requirements. The values are set by Project Manager and appropriate stakeholders to reflect the points at which corrective action will be taken to prevent exceeding specification limits. PMBOK 5E Ref #

31 Seven Basic Quality (7QC) Tools 6. Control Charts To monitor any type of output variable. For example: cost / schedule variations volume and frequency of scope changes errors in project documents Process is out of control if: - Data point exceeds a control limit - Seven consecutive points are above or below the mean When a process is outside acceptable limits, the process should be adjusted PMBOK 5E Ref #

32 Seven Basic Quality (7QC) Tools Control Chart 32

33 Seven Basic Quality (7QC) Tools Measurement Control Chart UCL Allowable Range of Variation Mean LCL 0 Time Beyond acceptable ranges 33

34 Seven Basic Quality (7QC) Tools Measurement Control Chart UCL Allowable Range of Variation Mean LCL 0 Possible problem - 7 points below (or above) the mean known as the Rule of 7 Time 34

35 Seven Basic Quality (7QC) Tools 7. Scatter Diagrams Aka correlation charts - seek to explain a change in the dependent and corresponding independent variable Dependent variables vs. Independent variables are plotted The plot can depict correlations inverse (negative) proportional (positive) no correlation (zero) If correlation exists, a regression line is calculated to estimate pattern of relationship between two variables PMBOK 5E Ref #

37 Seven Basic Quality (7QC) Tools Scatter Diagrams 37

38 Seven Basic Quality (7QC) Tools Scatter Diagrams No correlation Highly Positive 38

39 Benchmarking Compares actual measurements to those of other projects Provides a basis by which performance can be measured These other projects can be within the performing organization or outside of it and can be within the same or in other application area Allows analogies from projects in different area PMBOK 5E Ref #

40 Design of Experiment (DOE) Statistical method for products under development Framework for systematically changing elements of a process Helps highlight influencing factors that reveal the presence of interactions and synergy among the factors Helps identify which factors may influence a product variables Helps with optimization of products or processes PMBOK 5E Ref #

41 Statistical Sampling Involves choosing part of a population of interest for inspection For example, selecting ten engineering drawings at random from a list of seventy-five Sample frequency sizes should be determined for including number of tests, expected scrap etc. (Cost of Quality) PMBOK 5E Ref #

42 Additional Quality Planning Tools Used to better define the situation and manage quality: Brainstorming Force Field Analysis Nominal Group Technique Quality Management and Control Tools PMBOK 5E Ref #

78 Dr. Joseph Juran Developed the 10 Steps to Quality Improvement: 1. Build awareness of the need and opportunity for improvement 2. Set goals for improvement 3. Organize to reach the goals (establish a quality council, identify problems, select projects, appoint teams, designate facilitators) 4. Provide training 5. Carry out projects to solve problems 6. Report progress 7. Give recognition 8. Communicate results 9. Keep score 10. Maintain momentum by making annual improvement part of the regular systems and processes of the company PMBOK Ref #Supp. 78

79 Dr. Joseph Juran The five attributes of fitness for use : 1. Quality of design (different grades of quality) 2. Quality of conformance (training to keep products in specifications, tolerances motivations) 3. Availability, reliability and maintainability 4. Safety 5. Field use (the way the product will be used by the customer) 79
