FAQ

What does quality assurance actually do?

Quality assurance keeps processes and outputs on target. In practice, that can mean testing, checking workflows, reviewing results, and helping a team reduce errors before work reaches customers.

What are the four types of quality assurance?

Many companies group QA into process QA, product QA, system QA, and supplier QA. The naming can change by industry, but the aim stays the same, which is to keep quality steady across each part of work.

What are the four main types of quality costs?

The four main cost categories for quality are prevention costs, appraisal costs, internal failure costs, and external failure costs. Prevention plus appraisal help stop defects early, while internal and external failure costs show what defects can cost when they slip through.

How do I calculate the cost of quality?

Sum prevention and appraisal costs, then add internal and external failure costs. Many teams use that total to see how much they spend to keep quality high and how much defects cost when they appear.

What does QA outsourcing cost?

QA outsourcing costs vary by project scope, test depth, team size, and turnaround time. A small recurring review can cost far less than a full testing program for a complex product, so it helps to compare quotes with the same service scope.

What to do next

Use this list to build a short quote request with the same questions for each company. Ask what QA services they cover, how they handle your type of project, and what their process looks like from kickoff to final review.

Before you sign, confirm the service scope, the delivery timeline, and who will handle your work. If your project depends on a local office, also verify the location and the contact person you will work with.
