Describe the scope of work in detail. Please include a summary of key deliverables.
Kultrix provides a dedicated team that works inside our own processes across several product lines at once: customer portals for different clients, a web app for utility services, a React web product with new modules and API integrations, and an Android app for drivers. They cover development, QA and design, work in our GitLab with feature branches and release through test and production environments. Beyond development, they helped us find and pre-screen engineers for some of our own customers.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
The Kultrix team runs several of our product lines in parallel, which lets us take on more customer work without growing our own headcount. New portals and modules reach production through a proper test stage, and the team is bringing automated tests into the release process. When our needs changed, they adjusted the team quickly and without friction.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
With many parallel projects we sometimes had to align priorities more often than planned. Kultrix raised it early every time, so it never became a problem.
