Ask the Manufacturing Specialist: Quality Control Plans
Posted by Michael S. on January 28, 2016 in Manufacturer Focus

Mike S., Acuity’s own in-house manufacturing specialist, answers the question, “What is a Quality Control Plan?”

A Quality Control Plan (QCP) is a critical and important document for any manufacturing business. A QCP provides a documented, high-level description of methods used to minimize process and product variation and also outlines what a company does to monitor, correct, and improve on quality issues. A QCP sets the direction on what a company is doing to ensure products meet customer specifications and to monitor quality, as well as addressing deviations and failures. Many customers, as well as ISO certification requirements, call for manufacturing companies to have documented QCPs for all their processes in place.


QCPs are living documents that should be updated and maintained on a regular basis. Implementing a regular review and revision process helps assure that the manufacturing processes are running as smoothly as possible.


A QCP is the source for documenting important processes and product requirements. Requirements are expressed in measurable specifications and link directly to the manufacturer’s Standard Operation Procedures (SOP), Standard Operation Guidelines (SOG), and/or Work Instructions (WI). A good QCP should also include a company’s audit reviews.


The benefits of a QCP are in documenting:

  • The people involved and what roles and responsibilities they have.
  • How often items will be reviewed, who is responsible for checking, and what needs to be done when a check is outside the specification limits.
  • What data is important to track and how it will be collected, stored, analyzed, and monitored.
  • A summary of the quality control process.
  • Process requirements and expectations of all involved.
  • Steps to be taken if a process is out of control.
  • Corrective actions, problem solving, and process-improvement tools and steps.


A company should have quality plans for each operation, all the way from material management to painting. This will help all external and internal people know the details of their processes as well as assist in making corrections and documenting changes.

Michael S. is our Manufacturing guru
I have over 30 years experience in a broad range of manufacturing areas. Starting with an apprenticeship in Germany I’ve worked my way through a variety of positions within the manufacturing field. I got my start as a Tool and Die maker. I next became a supervisor of a class A tool room, then manager of a machining department. I was exposed to lean manufacturing in the mid 90s and adapted the lean philosophy. Loving and teaching the lean approach, I moved on to become a Continuous Improvement manager which led to a job as a manufacturing manager. I joined Acuity in 2015 as their manufacturing expert. I hope to evolve how manufacturers deal with and think about insurance companies, as well as be a resource to my fellow employees – enabling them to better understand the unique needs of manufacturers.

When you hear the word hybrid, many things may come to mind. You might think about cars that have a combination of electric and combustion engines to propel them or plants that have been genetically modified to grow in adverse conditions or achieve higher yields. Regardless of what comes to mind, the term hybrid refers to the combination of two or more unlike things.

For many manufacturing companies, technology seems to help with improvements in a variety of areas, including quality, on-time delivery, reduction in part costs, and much more. However, technology can only get you so far. If you do not embrace lean manufacturing practices, you will never reap the full benefits of the technology or systems you are implementing. In short, lean manufacturing is as relevant today as it was when it first came into manufacturing.
