Intro to Project Management: Project Quality Management Quality Assurance Process Analysis Quality Audits

What This Is

Quality Assurance (QA) is the process of ensuring that a project meets its quality standards and requirements. It involves planning, executing, and controlling activities to prevent defects and ensure that the project deliverables meet the expected quality. For example, when building a bridge, QA would involve inspecting the materials, testing the structural integrity, and ensuring that the bridge meets the safety standards.

Key Terms & Formulas

• Quality Management Plan: A document that outlines the quality policies, procedures, and standards for the project.
• Quality Metrics: Quantifiable measures used to evaluate the quality of project deliverables (e.g., defect density, cycle time).
• Defect Density: The number of defects per unit of work (e.g., defects per thousand lines of code).
• Cycle Time: The time it takes to complete a task or deliver a product.
• Root Cause Analysis (RCA): A method used to identify the underlying causes of defects or problems.
• Corrective Action: A plan to address defects or problems identified during the project.
• Preventive Action: A plan to prevent defects or problems from occurring in the future.
• Quality Audit: An independent review of a project's quality management processes and results.
• Audit Trail: A record of all changes made to a project's quality management plan or processes.
• Earned Value (EV) = % complete × BAC (Earned Value = percent complete times Budget at Completion).
• Cost Performance Index (CPI) = EV / AC (Cost Performance Index = Earned Value / Actual Cost).
• Schedule Performance Index (SPI) = EV / BCWS (Schedule Performance Index = Earned Value / Budgeted Cost of Work Scheduled).

Step-by-Step / Process Flow

1. Develop a Quality Management Plan: Create a document that outlines the quality policies, procedures, and standards for the project.
2. Identify Quality Metrics: Determine the metrics that will be used to evaluate the quality of project deliverables.
3. Conduct Quality Audits: Perform regular audits to ensure that the project is meeting its quality standards and requirements.
4. Analyze Defects: Identify and analyze defects or problems that occur during the project.
5. Implement Corrective and Preventive Actions: Develop plans to address defects or problems and prevent them from occurring in the future.
6. Monitor and Control Quality: Continuously monitor and control quality throughout the project.

Common Mistakes

• Mistake: Failing to develop a Quality Management Plan.
• Correction: Develop a Quality Management Plan that outlines the quality policies, procedures, and standards for the project.
• Why: A Quality Management Plan provides a framework for ensuring that the project meets its quality standards and requirements.
• Mistake: Not conducting regular quality audits.
• Correction: Conduct regular quality audits to ensure that the project is meeting its quality standards and requirements.
• Why: Quality audits help identify defects or problems early, reducing the risk of project failure.
• Mistake: Failing to analyze defects.
• Correction: Analyze defects or problems to identify the root cause and develop corrective and preventive actions.
• Why: Analyzing defects helps identify areas for improvement and reduces the risk of future defects.

Exam Tips

• Quality Assurance vs Quality Control: Quality Assurance is the process of ensuring that a project meets its quality standards and requirements, while Quality Control is the process of monitoring and controlling quality throughout the project.
• Contingency vs Management Reserve: Contingency is a plan for dealing with unexpected events, while Management Reserve is a portion of the budget set aside for unexpected expenses.
• Root Cause Analysis (RCA) vs Fishbone Diagram: RCA is a method used to identify the underlying causes of defects or problems, while a Fishbone Diagram is a visual tool used to identify the possible causes of a problem.

Quick Practice Questions

1. If the CPI is 0.8, is the project under or over budget? Answer: Under budget. Explanation: A CPI of 0.8 indicates that the project is earning 80% of its budgeted value, indicating that it is under budget.
2. If the EV is $100,000 and the BAC is $200,000, what is the percent complete? Answer: 50%. Explanation: Using the formula EV = % complete × BAC, we can calculate the percent complete as EV / BAC = $100,000 / $200,000 = 0.5 or 50%.
3. If the SPI is 1.2, is the project ahead or behind schedule? Answer: Ahead schedule. Explanation: A SPI of 1.2 indicates that the project is earning 120% of its budgeted value, indicating that it is ahead schedule.
