There is a difference between Quality Control and Quality Assurance.

One area of peak confusion for our clients lies in understanding the roles of Quality Control and Quality Assurance. Each, after all, is pivotal for the success of any given initiative (and neither can function to its full utility without cooperation from the other). And, as varying methodologies and challenges always create unique landscapes, Quality Practices must remain flexible enough to navigate through project requirements for any client without compromising the integrity of solutions being created.


Quality Control is generally understood as the “test and review” process of product development. Here, dedicated team members look to uncover weaknesses in a solution, and then to create reports which aid improvement. Common steps within this process include:

  • Technical Testing (Unit, Integration/Assembly and Performance Testing)
  • Business Testing (System Test and UAT)


Quality Assurance, by contrast, is work done throughout development. These processes aim to streamline the development of a product and to prevent inefficiencies in its final state. Examples from this stage may include:

  • Entry/Exit Criteria
  • Stage Containment
  • Verification and Validation of Deliverables
  • Baseline and Signoff


While every successful initiative should carry some combination of these practices, underlying methodology for execution must vary between projects. After all, no two solutions are identical, so their components—and construction—should be custom-tailored to achieve maximum utility. In this, Trillium’s decades of professional acumen are second-to-none.
