Education Edge PMP Prep Course Office Read – Project Quality Management


Project Quality Management


§  Quality: the degree to which a set of inherent characteristics fulfills requirements, decrease rework/costs, increase productivity/stakeholder satisfaction


§  everyone in the organization is responsible for the quality (project team for destined parts while PM for project quality), the project manager is ultimately responsible for the project quality


§  The project manager is required to perform continuous improvement activities (quality assurance), verify quality before completion of deliverables (control quality)


§  prevention over inspection


§  continuous improvement to ensure quality (quality assurance) — Quality Management processes are so focused on reviewing EVERY deliverable – not just the final product, but all of the components, designsand specifications too.


§  some costs of quality will be borne by the organization (organization quality policy, e.g. quality audit, ISO accreditation)


§  Quality Management Concepts


§  Crosby Zero Defects: identify processes to remove defects, quality is built in to the processes


§  Juran Fitness for Use: does the product/service meet customer’s need? i) Grade, ii) Quality conformance, iii) Reliability/maintainability, iv) Safety, v) Actual Use


§  W. Edwards Deming: 85% of quality problem is managers’  responsibility, develop “System of Profound Knowledge” [system = components working together to achieve an aim] i) Appreciation for system, ii) Knowledge about variation (special cause vs common cause) , iii) Theory of Knowledge (built up by prediction/observation/adjustment) , iv) Psychology


§  Six Sigma: achieve 3.4/1 mil defect level (99.999%) using DMAIC (Define, Measure, Analyze, Implement, Control) or [Design for Six Sigma] DMADV (Define, Measure, Analyze, Design, Validate) approach, refine the process to get rid of human error and outside influences with precise measurements, variations are random in nature


§  Just In Time: eliminate build up of inventory


§  Total Quality Management (TQM): ISO 8402 all members to center on quality to drive customer satisfaction , refine the process of producing the product


§  Kaizen: implement consistent and incremental improvement, to reduce costs, cycle time, drive customer satisfaction using PDCA (Plan Do Check Act)


§  The Plan-Do-Check-Act cycle is a way of making small improvements and testing their impact before you make a change to the process as a whole. It comes from W. Edwards Deming’s work in process improvement, which popularized the cycle that was originally invented by Walter Shewhart in the 1930s.


§  Capability Maturity Model Integration (CMMI): improve overall software quality (design, development and deployment)


§  ISO9000: ensures the defined processes are performed in accordance to the plan
§  Important Terms:


§  outliers are singular measurements outside the control limits




§  under control: the process is predictable and repeatable


Plan Quality Management


§  Inputs: Project Charter, Project Management Plan, Project Documents (assumption log, requirements traceability matrix, risk register, stakeholder register), EEF, OPA


§  Tools & Techniques: Expert Judgement, Data Gathering, Data Analysis, Decision Making, Data Representation, Test and Inspection Planning, Meetings


§  Outputs: Quality Management Plan, Quality Metrics, Project Management Plan Updates, Project Documents Updates


§  quality policy (either organizational or just for the project), methods and procedures to meet the objectives and satisfy customer’s needs


§  including identifying the quality requirements and document how to achieve


§  The goal is to refine the process so that human errors and outside influences no longer exist, and any remaining variations are completely random


§  Quality Metrics: function points, MTBF (mean time between failure), MTTR (mean time to repair)


§  Data Gathering Tools:


§  Benchmarking: compare to past activities/standard/competition


§  Brainstorming


§  Interviews


§  Data Analysis tools:


§  Cost-benefit Analysis: cost of implementing quality requirements against benefits


§  Cost of Quality:


§  Cost of Quality is the total cost of quality efforts throughout the product’s lifecycle


§  cost of conformance + cost of non-conformance: cost of conformance (prevention cost, appraisal cost) vs cost of non-conformance (failure cost [internal/external])


§  lowest quality cost is prevention, highest quality cost (poor quality) is rework and defect repair (as high as 5000 times the cost for carrying out unit testing), lost reputation and sales, failure cost may be internal/external (found by customer)


§  Warranty claims are external cost of quality — internal/external is reference to the project (not the organization)


§  Cause-and-effect / Ishikawa / Fishbone Diagram: for identifying the cause


§  Flowchart: (e.g. SIPOC diagram) for identifying failing process steps and process improvement opportunities


§  Check Sheets (tally sheets)collecting data/documenting steps for defeat analysis


§  Histograms: does not consider the influence of time on the variation that exits within a distribution


§  Pareto Chart: based on 80/20 principle, a prioritization tool to identify critical issues in descending order of frequency, sort of a histogram


§  Statistical Process Control (SPC) Chart: determine if a process is stable/predictable using statistical sampling (assessed by accuracy[conformance] and precision[standard deviation]), identity the internally computed control limits (UCL/LCL) and specification limits (USL/LSL) by the customer/PM


§  run chart is similar to control chart, but without the control


§  usually +-3sigma i.e. a range of 6 sigma


§  a form of time series


§  if a process is within control limit but beyond specification limit, the process is experiencing common cause variation (random) that cannot be corrected by the system, management help is needed (special cause can be tackled but NOT common cause)


§  Stability Analysis / Zone Test: rule of seven (7 consecutive on either side of the mean = out of control), rule of six (six consecutive with a trend = out of control), rule of ten (10 as a saw-tooth pattern around the mean), rule of one (1 point beyond control limit) [signal in the noise]


§  Scatter Diagram: for trending, a form of regression analysis


§  Data Representation tools:


§  Flowcharts


§  Logical data model


§  Matrix Diagrams: House of Quality (HOQ) used in Quality Function Deployment (QFD) (method to transform user demands [VOC]  into design quality)


§  Mind mapping


§  Test and Inspection Planning


§  used to determine how to test or inspect the product, deliverable, or service to meet the stakeholders’ needs and expectations


§  alpha/beta releases


§  inspections


§  field tests


§  Other quality tools:


§  Design of Experiments (DOE): change several factors at a time for each experiment, to determine testing approaches and their impact on cost of quality


§  Loss Function: a financial measure of the user’s dissatisfaction with product performance


§  Kano Model: differentiate features as satisfy, delight or dissatisfy


§  Marginal Analysis: cost-benefit analysis


§  Force Field Analysis (FFA): reviews any proposed action with proactive and opposing forces


§  Process Improvement Plan: process boundaries, configuration, process metrics/efficiencies, targets for improved performance


§  Quality Checklists: checklist to verify a series of steps have been performed


§  Marginal Analysis: ROI of quality measures
