Testimonial: Johnson Controls
A closer look at how our collaboration helped this company achieve meaningful results.
Development
Johnson Controls had a mature hardware platform and software suite for industrial refrigeration control systems, but the software was out of date and required modernization. They engaged an external partner and turned to Limestone Digital for first-class technical support. The collaboration focused on building software for real industrial environments, where quality, security, and reliability are critical due to operational and human risks. Limestone maintained high standards through structured processes and delivered a product that meets their exact needs and can be inserted directly into their production process path with minimal effort — helping the company move forward and continue development.
Engagement overview
The engagement involved close collaboration with a small internal team, where Limestone Digital contributed not only to development but also to defining detailed requirements and refining the existing system. This included working with an existing codebase and ensuring correct interaction with hardware. The delivery approach evolved over time — starting with a tailored process and gradually transitioning to agile as the client’s internal capabilities matured. Throughout the project, the team adapted to personnel changes and organizational shifts, maintaining continuity and supporting long-term product development.
Highlights
