Quality Assurance Vs Quality Control

5 minutes 5 Questions

Quality Assurance (QA) and Quality Control (QC) are two interrelated but distinct concepts in project management. QA focuses on the processes used to produce project deliverables, ensuring that they consistently meet the established quality requirements and standards. It is proactive, aiming to prevent defects and non-conformance issues by identifying and addressing process inefficiencies early in the project life cycle. QC, on the other hand, concentrates on the inspection and verification of project deliverables to ensure they meet the required quality expectations. The primary goal is to identify and address defects and non-conformance issues after they have occurred. Both QA and QC are essential components of effective quality management and contribute to the overall success of a project.

Guide: Quality Assurance Vs Quality Control

Introduction:
Quality Assurance and Quality Control are two fundamental aspects of Project Management Body of Knowledge(PMBOK), often tested in PMP examination.

Quality Assurance:
Quality Assurance, often referred to as QA, is a process-focused practice that lays emphasis on the prevention of defects. It involves the formulation of a set of guidelines or standards which should be adhered to, in order to meet the desired level of quality.

Quality Control:
On the other hand, Quality Control, also known as QC, is product-focused. It involves verification of the output to ensure that the end product adheres to the set standards.

Importance:
Understanding the distinction between Quality Assurance and Quality Control is crucial as they both have different aims. While Quality Assurance is about preventing defects with a focus on the process, Quality Control is about identifying and correcting defects in the finished product.

Exam Tips:
During exams, remember to distinguish between QA and QC based on the context of the problem statement. QA relates to how the process is being performed, irrespective of the output, while QC focuses on the examination of the deliverables.

Some typical QA activities: Process checklists, Project audits, Process documentation.
Some typical QC activities: Design reviews, Code inspection, Testing.

In Conclusion:
Quality Assurance and Quality Control are integral to PMBOK and understanding the distinction between the two is crucial for a good score in the PMP exam.

Question 1

In a project activity, a process produces results that do not meet the expected standards. The project manager asks the team to apply a preventive action. What process is the project manager implementing?

Correct Answer: Quality Control

Based on the given scenario, the project manager is implementing Quality Control. Quality Control is the process of monitoring and recording the results of project activities to assess performance and ensure the project outputs meet the defined quality standards. When the process produces results that do not meet the expected standards, the project manager asks the team to apply a preventive action, which is a characteristic of the Quality Control process. The other options are: - Quality Assurance: This process focuses on auditing the quality requirements and the results from quality control measurements to ensure that appropriate quality standards and operational definitions are used. - Quality Management: This is the overarching process that includes all the activities of the performing organization that determine quality policies, objectives, and responsibilities so that the project will satisfy the needs for which it was undertaken. - Quality Planning: This process identifies the quality requirements and/or standards for the project and its deliverables, and documents how the project will demonstrate compliance with quality requirements. Therefore, the project manager in the given scenario is implementing the Quality Control process.

Question 2

During a project audit, the auditor discovered a lack of quality documentation. What is the most appropriate action for the project manager to take?

Correct Answer: Implement Quality Assurance processes

The most appropriate action for the project manager when a lack of quality documentation is discovered during a project audit, is to Implement Quality Assurance processes. Quality Assurance provides a framework for systematically monitoring and evaluating the various aspects of a project, service or facility to ensure that standards of quality are being met. It focuses on improving the process of delivering quality and helps prevent faults from occurring. On the other hand, focusing only on Quality Control, which is reactive in nature and takes place after the product is built, may not entirely address the problem of lacking quality documentation. Continuing the project without addressing the issue is not an appropriate option as it will likely lead to further quality issues. Requesting additional budget and resources may be helpful in some situations, but it's not an immediate step to take towards resolving the quality documentation issue. Instead, implementing quality assurance processes would help in creating documentation procedures to capture the necessary information.

Question 3

A client is repeatedly finding defects in the delivered product, causing delays in implementation. What action should the project manager take to minimize defects and improve overall quality?

Correct Answer: Incorporate Quality Assurance to improve processes

The best action for the project manager to take in order to reduce defects and improve overall quality is to 'Incorporate Quality Assurance to improve processes'. Quality Assurance is a proactive process which seeks to prevent defects before they occur by focusing on the processes used in the project. By improving these processes, the probability of defects can be decreased significantly, leading to improved overall quality of the project. Focusing solely on Quality Control is not the most suitable option because Quality Control is a reactive process which identifies and corrects defects after they have occurred. It does not prevent defects from occurring in the first place. Changing the project scope does not directly address the issue of defects or quality improvement. It may even lead to additional risks and issues if not managed correctly. Requesting additional funding may be helpful in hiring more resources or getting better quality materials, but it will not ensure defect reduction or quality improvement unless accompanied by effective quality management practices.
