    The terms Quality Assurance and Quality Control are often used interchangeably but are they really the same? Can you describe any key differences or similarities between Quality Assurance and Quality Control?

    Qualty assurance is process oriented while quality control is product oriented. Quality assurance deals with developing processes and systems that align with QMS while Quality assurance is all about monitoring products.

    Yes. These are two different things. Although some people think that it is the same thing. The main difference is their aim. Quality control is aimed to detect problems, while quality ensuring is aimed to prevent occurring such problems.

    Quality assurance is the big master plan of quality procedures and systematic activities that are followed to ensure a high quality end product, while quality control is the attention to detail or actually inspecting products and manufacturing procedures to ensure that end products are not defective. The quality control aspect might involve finding and eliminating flawed products that are coming off the assembly line so they are not distributed to customers.

    Quality Assurance is to Developing Processes which Assure End Quality as Decided in SMART Goals. Quality Control is to check if any process does not result the objective outcome as defined in SMART Objectives. Hence Quality Control is to define the reasons and bring back the Quality if any process does not result the end outcome

    according to the PMBOK:

    Perform Quality Assurance >>>

    Perform Quality Assurance is the process of auditing the quality requirements and the results from quality control measurements to ensure that appropriate quality standards and operational definitions are used. The key benefit of this process is that it facilitates the improvement of quality processes.

    It is important to notice that PQA is a Execution process, after Planning. Also it is part of Conformance (COQ), avoiding failures during the project.

    Read on, don't get confused...

    Control Quality >>>

    Control Quality is the process of monitoring and recording results of executing the quality activities to assess performance and recommend necessary changes. The key benefits of this process include: (1) identifying the causes of poor process or product quality and recommending and/ or taking action to eliminate them; and (2) validating that project deliverables and work meet the requirements specified by key stakeholders necessary for final acceptance.

    It's a Monitor & Control Process Group item.

    THIS IS IMPORTANT:

    According to Ch 8.3 PMBOK:

    'The Control Quality process uses a set of operational techniques and tasks to verify that the delivered output will meet the requirements. QA should be used during the project's planning and execution phases to provide confidence that the stakeholder's requirements will be met and quality control should be used during the project execution and closing phases to formally demonstrate, with reliable data, that the sponsor and/or customer's acceptance criteria have been met.'


    Kind regards

    Adding a different perspective from conventional delivery methods :- Quality assurance is a bigger bucket under which quality control swims. QA shields QC by using process and best practices etc.

    Quality control is more oriented on the producing the materialistic artefacts such as Test results , Risk management , End 2 End delivery where as Quality assurance drives all these activities .

    QC folks are doers and QAE are the ensurers.

    In Agile this definition may not hold good.
