Quality control (QC) is a process through which manufacturers or any other businesses seek to ensure that product and service quality is maintained or improved with either reduced or zero errors. Quality control requires the business to create an environment in which both management and employees strive for perfection – Total Quality Management. Most often, it involves thoroughly examining and testing the quality of products or the results of services. The basic goal of this process is to ensure that the products or services that are provided meet specific requirements and characteristics, such as being dependable, satisfactory, safe and fiscally sound.
If you want to make sure you are providing consistent products or services throughout your organization, you must implement an ironclad quality management system, or QMS. Quality control management ensures that what your company delivers and the delivery processes it uses are cohesive and that every business phase of the organization focuses on the same goal. When broken down, quality control management can be segmented into four key components to be effective: quality planning, quality control, quality assurance, and quality improvement. Quality Control Planning.
The first step of quality management is planning. You need to take the time to identify your goals and what you want your baseline to be. You should determine what your quality standards are, the requirements necessary to meet these standards, and what procedures will be used to check that these criteria are being met. In this planning stage, you will want to consider:
- What your stakeholder’s expectations and priorities are, if applicable
- What your company’s definition of success is
- What legal standards or requirements are in place that must be abided by
- Who will handle each role in the quality management process (supervision, testing, etc.?
- How often processes will be evaluated for improvement
- Quality Control
Once you have a plan in place, quality control comes into play. This is the process of physically inspecting and testing what you laid out in the planning stage to make sure it is obtainable. You need to confirm that all the standards you have put into place are met, and you need to identify any mishaps or errors that need to be corrected. The sooner you can catch these errors, the better. As such, you should be paying attention to all aspects of the product, including both the materials used and the process of putting them together.
Once the inspection data has been collected, it should be displayed in a way that makes it easy to analyze. You can create histograms, run charts, or cause and effect display, and then easily share them through your document management Documentation Kit to make sure everyone has access to them.
- PLAN a change aimed at improvement:
- Analyze current condition
- Identify exactly what your problem is
- Map the process
- Establish the objectives
- DO – Carry out the change
- Implement the plan
- Generate possible solutions
- execute the process
- make the product.
- Collect data for charting and analysis in the following "CHECK" and "ACT" steps.
- CHECK/Study the results
- Study the actual results (measured and collected in "DO" above)
- Against the expected results
- ACT - Adopt, adapt, or abandon
- Take action based on what you learned in the study step
- Two Possibilities:
- If the change did not work, go through the cycle again with a different plan.
If you were successful then standardize.
