8.3 Control Quality

Description: the process of monitoring and recording results of executing the quality management activities in order to assess performance and ensure the project outputs are complete, correct and meet customer expectations. It determines if the project outputs do what they were intended to do. Those outputs need to comply with all applicable standards, requirements, regulations, and specifications. The process is performed to measure the completeness, compliance, and fitness for use of a product or service prior to user acceptance and final delivery. It is done by measuring all steps, attributes, and variables.

Key benefit: verifying that project deliverables and work meet the requirements specified by key stakeholders for final acceptance.

Frequency: throughout the project.

8.3.1 Inputs

8.3.1.1 Project Management Plan

Quality management plan: how quality control will be performed.

8.3.1.2 Project Documents

Include:

• Lesson learned register.
• Quality metrics. Project/product attributes and how compliance will be verified to them.
• Test and evaluation documents.

8.3.1.3 Approved Change Requests

May include modifications such as

• Defect repairs,
• Revised work methods,
• Revised schedules.

8.3.1.4 Deliverables

Any unique and verifiable product, result, capability to perform a service that is required to be produced to complete a process, phase, project.

8.3.1.5 Work Performance Data

Data on product status such as observation, quality metrics, measurements for technical performance, project quality performance, cost performance.

8.3.1.6 Enterprise Environmental Factors

Include:

• Project management informational system.
• Government agency regulations.
• Rules, standards, guidelines.

8.3.1.7 Organizational Process Assets

Include:

• Quality standards and policies;
• Quality templates:
  • Check sheets,
  • Check lists,
  • Others.
• Issue and defect reporting procedures and communication policies.

8.3.2 Tools and Techniques

8.3.2.1 Data Gathering

Include:

• Checklists.
• Check sheets.
• Statistical sampling. Inspection of the part of the population.
• Questionnaires and Surveys. Customer satisfaction after the deployment.

8.3.2.2 Data Analysis

Include:

• Performance review.
• Root cause analysis (RCA).

8.3.2.3 Inspection

The examination of a work product to determine if it conform to documented standards. Include measurements. May be called:

• Reviews,
• Peer reviews,
• Audits,
• Walkthroughs.

8.3.2.4 Testing/Product Evaluations

The intent of testing is to find errors, defects, bugs, or other non-conformance problems. The type, amount, and extent of tests needed to evaluate each requirement are part of the project quality plan and depend on the nature of the project, time, budget, and other constraints. Tests can be performed throughout the project, as different components of the project become available, and at the end of the project on the final deliverables. Early testing helps identify non-conformance problems and helps reduce the cost of fixing the nonconforming components.

8.3.2.5 Data Representation

• Cause-and-effect diagrams.
• Control charts. To determine whether or not a process is stable or has predictable performance. Upper and lower level limits. The control limits are determined using standard statistical calculations and principles to ultimately establish the natural capability for a stable process.
• Histograms.
• Scatter diagrams.

8.3.2.6 Meetings

• Approved change requests review.
• Retrospectives/lesson learned.
  • Successful elements in the project/phase,
  • What could be improved,
  • What to incorporate in the ongoing project and what in future project,
  • What to add to the organization process assets.

8.3.3 Outputs

8.3.3.1 Quality Control Measurements
