What happened
Automated IOQQ worked, but wasn't built to scale.
This company manufactures chemical analysis equipment used in pharmaceutical, food & beverage, and chemical industry labs worldwide. Their products are known for high quality standards, which is a real competitive advantage in this market.
Field service engineers perform IQOQ (Installation Qualification, Operational Qualification) at customer sites using automated test execution. It was working, but every new software version required extra effort to keep things stable. And the team had bigger plans: they wanted to roll out automated IOQQ across more devices over time.
For that, they needed a solution that runs on customer computers without installing anything, works without internet access, isn't tied to any specific technology, and produces reports that look exactly like the existing ones. The IOQQ report is what the customer pays for, and its quality is what sets this company apart from competitors.
Their existing tool wasn't stable across software versions and couldn't cover new device technologies. Finding a replacement turned out to be harder than expected.
How they fixed it
A tool built for MedTech that runs from a USB stick at customer sites
After evaluating multiple tools, only TestResults met every requirement. It offers an IOQQ license that doesn't need internet or installation. It runs from a USB stick directly on the customer's computer.
The team recreated their existing report format inside TestResults so customers see no difference. Same layout, same level of detail, same compliance value.
Setup took 20 days. Their previous solution had taken several months.
faster IOQQ execution on every run
saved per year in field service on-site time
from start to fully automated IOQQ
What changed
33% faster IQOQ. 700+ hours saved per year. Instant releases.
The original goal was a stable, technology-independent solution that could scale to more devices. They got that.
What they didn't expect: the IQOQ runs 33% faster than before. No special steps, no workarounds to keep things stable. That saves the field service engineers over 700 hours of on-site time per year.
When a new software version is released, IQOQ test cases are adjusted in days, not weeks. The gap between software release and IQOQ availability, which used to be one to two weeks, is gone.
Since the launch, the team has received fewer than 10 support tickets. The built-in reports and logs are easy to read, so most issues get resolved without escalation. Almost all tickets turned out to be user-related or actual bugs in the software being tested, not in TestResults. For a tool that runs on thousands of customer computers across the world without internet access, that says more than any stability metric could.
Looking back, the team regrets not switching sooner.
