Aim: To understand the Plan Quality process
Although the project manager has overall responsibility for quality, the entire project team plays a role in quality management. Every member of the project team must understand the importance of contributions, accept ownership for problems, be committed to monitoring and improving performance, and be willing to openly discuss issues among team members. Although specific techniques and measures apply to the product being produced, the overall project quality management approach applies to any project and is relevant to the project as well as the product being produced.
Understand the difference between quality and grade. Quality is a measure of how well the characteristics match requirements. Grade is assigned based on the characteristics that a product or service might have. So a product might be of low grade, meaning it has limited features, but might still be acceptable. Low quality is never acceptable.
Also, you need to understand the difference between precision and accuracy. According to the PMBOK, “Precision means the values of repeated measurements are clustered and have little scatter. Accuracy means that the measured value is very close to the true value. Precise measurements are not necessarily accurate. A very accurate measurement is not necessarily precise.”
The Plan Quality Process:
The plan quality process has a number of key inputs, many of which originate from other initiating and planning processes. The table below shows the inputs, tools and techniques, and outputs for the plan quality process.
|Inputs||Tools & Techniques||Outputs|
Cost performance baseline
Enterprise environmental factors
Organizational process assets
Cost of quality
Design of experiments
Proprietary quality management methodologies
Additional quality planning tools
Quality management plan
Process improvement plan
Project document updates
• The cost of preventing mistakes is generally less than the cost of repairing them.
• In order to be successful, management support for the quality program must exist.
• Quality is tied closely to the scope-cost-time constraints; without quality these objectives cannot be met successfully.
• The cost of quality refers to the cost to implement a quality program.
• Understanding and managing customer expectations is important to a successful quality program.
• The quality program should emphasize continuous improvement.
• There is a close alignment between the quality approach and the overall project management approach on a project.
PMI’s definition of quality: “The degree to which a set of inherent characteristics fulfill requirements.”
