Survey of the entire population yields

accurate data

A measurement is a

actual value

Gold-plating

certain features are added to the deliverable which were not asked for by the customer, to earn customer appreciation. It is not a recommended project management practice

International Organization for Standardization (ISO)

compatible with proprietary approaches to quality management such as those recommended by Deming, Juran, Crosby, and others, and non-proprietary approaches such as Total Quality Management (TQM), Six Sigma, failure mode and effect analysis (FMEA), design reviews, voice of the customer, cost of quality (COQ), and continuous improvement

Cost of Quality (COQ)

refers to the total cost of all efforts related to quality throughout the product life cycle Project decisions can impact operational costs of quality as a result of product returns, warranty claims, and recall campaigns. Therefore, due to the temporary nature of a project, the sponsoring organization may choose to invest in product quality improvement, especially defect prevention and appraisal, to reduce the external cost of quality

Lessons learned are documented throughout the project life cycle, but at a minimum, during project closure.

Project Management Plan Use in Perform Quality Control

• Contains the quality management plan, which is used to control quality • The quality management plan describes how quality control will be performed within the project

Quality and Project Management Disciplines both recognize the importance of...

• Customer satisfaction. • Prevention over inspection • Continuous improvement • Management responsibility • Cost of quality (COQ)

Characteristics of DOE

• DOE should be used during the Plan Quality process to determine the number and type of tests and their impact on cost of quality. • DOE also plays a role in the optimization of products or processes. • DOE can be used to reduce the sensitivity of product performance to sources of variations caused by environmental or manufacturing differences. • One important aspect of this technique is that it provides a statistical framework for systematically changing all of the important factors, rather than changing the factors one at a time. • Analysis of the experimental data should provide the optimal conditions for the product or process, highlight the factors that influence the results, and reveal the presence of interactions and synergy among the factors

Areas to Consider in the Process Improvement Plan

• Process boundaries • Process configuration • Process metrics • Targets for improved performance

Plan Quality: Project Document Updates

• Project documents that may be updated include, but are not limited to: • Stakeholder register, and • Responsibility Assignment Matrix

Characteristics of Perform Quality Assurance

• Provides an umbrella for continuous process improvement, which is an iterative means for improving the quality of all processes. • Continuous process improvement reduces waste and eliminates activities that do not add value. • This allows processes to operate at increased levels of efficiency and effectiveness

Characteristics of the Quality Management Plan

• Provides input to the overall project management plan and includes quality control, quality assurance, and continuous process improvement approaches for the project. • May be formal or informal, highly detailed, or broadly framed. The style and detail is determined by the requirements of the project. • Should be reviewed early in the project to ensure that decisions are based on accurate information. • The benefits of this review can include reduction of cost and schedule overruns caused by rework

Perform Quality Assurance: Project Document Updates

• Quality audit reports • Training plans • Process documentation

Characteristics of Perform Quality Control

• Quality control is performed throughout the project • Quality control is often performed by a quality control department or similarly titled organizational unit. • Quality control activities identify causes of poor process or product quality and recommend and/or take action to eliminate them • The project management team should have a working knowledge of statistical quality control, especially sampling and probability, to help evaluate quality control outputs.

Perform Quality Assurance: Change Requests

• Quality improvement includes taking action to increase the effectiveness and/or efficiency of the policies, processes, and procedures of the performing organization. • Change requests are created and used as input into the Perform Integrated Change Control process to allow full consideration of the recommended improvements. • Change requests can be used to take corrective action or preventive action or to perform defect repair

Characteristics of Statistical Sampling

• Sample frequency and sizes should be determined during the Plan Quality process so the cost of quality will include the number of tests, expected scrap, etc. • There is a substantial body of knowledge on statistical sampling. In some application areas it may be necessary for the project management team to be familiar with a variety of sampling techniques to assure the sample selected actually represents the population of interest

Elements of Scope Baseline Use in Plan Quality

• Scope statement. • WBS. • WBS Dictionary.

Trend Analysis is often used to monitor

• Technical Performance • Cost and Schedule Performance

Characterisitics of Control Charts

• The appropriate data is collected and analyzed to indicate the quality status of project processes and products. • They graphically answer the question: "Is this process variance within acceptable limits?" • The pattern of data points on a control chart may reveal random fluctuating values, sudden process jumps, or a gradual trend in increased variation. • By monitoring the output of a process over time, a control chart can help assess whether the application of process changes resulted in the desired improvements. • When a process is within acceptable limits it is in control and does not need to be adjusted. • Conversely, when a process is outside acceptable limits, the process should be adjusted. • Seven consecutive points above or below the central line indicate a process that is out of control. • The upper control limit and lower control limit are usually set at ±3σ, where 1σ is one standard deviation

Quality Policy Use in Plan Quality

• The quality policy of the performing organization for their products often can be adopted "as is" for use by the project. • If the performing organization lacks a formal quality policy, or if the project involves multiple performing organizations (as with a joint venture), the project management team will need to develop a quality policy for the project. • Regardless of the origin of the quality policy, the project management team must ensure that the project stakeholders are fully aware of the policy used for the project through the appropriate distribution of information

Characteristics of Inspection

• The results of an inspection generally include measurements and may be conducted at any level. • In some application areas, these terms have narrow and specific meanings. • Inspections are also used to validate defect repairs

Characteristics of Quality Audits

• The subsequent effort to correct any deficiencies should result in a reduced cost of quality and an increase in sponsor or customer acceptance of the project's product. • Quality audits may be scheduled or random and may be conducted by internal or external auditors. • Quality audits can confirm the implementation of approved change requests including corrective actions, defect repairs, and preventive actions

Characteristics of Flowcharting

• There are many styles, but all process flowcharts show activities, decision points, and the order of processing. • During quality planning, flowcharting can help the project team anticipate quality problems that might occur. • An awareness of potential problems can result in the development of test procedures or approaches for dealing with them

Characteristics of Control Limits

• Upper and lower control limits are set by the project manager and appropriate stakeholders to reflect then points at which corrective action will be taken to prevent exceeding specification limits. • For repetitive processes, the control limits are generally ± 3σ. • A process is considered out of control when a data point exceeds a control limit or if seven consecutive points are above or below the mean

Quality vs Grade

• While a quality level that fails to meet quality requirements is always a problem, low grade may not be. • The project manager and the project management team are responsible for managing the tradeoffs involved to deliver the required levels of both quality and grade

Failure Costs include

• costs to rework products, components, or processes that are non-compliant; • costs of warranty work and waste; and • costs due to loss of reputation

Characteristics of Cause and Effect Diagrams

• possible root cause can be uncovered by continuing to ask "why" or "how" . • "Why-Why" and "How-How" diagrams may be used in root cause analysis. • Cause and effect diagrams are also used in risk analysis
