platform migration

A leading U.S. manufacturer of heavy-duty diesel engines used specialist software to retrieve operating and performance data under different working conditions, transfer it to PCs and generate reports that help keep engines running efficiently.

Challenge

01

The ageing C++ application needed a technology upgrade without reducing its operational efficiency.

02

New engine products and Windows versions required continuous functional and compatibility updates.

03

Testing a new communications project required knowledge of electronic CAN hardware that was not available through a dedicated specialist tester.

Solution

Migrated the engine performance platform to C#, maintained it across changing Windows and product requirements, and expanded the collaboration into CAN-connected product development.

How we worked

01

Analysed the existing application and migrated core functionality from C++ and COM components to C# and WinForms.

02

Preserved the workflow for collecting engine data, transferring it to PCs and producing analysis reports.

03

Expanded from individual maintenance tasks to end-to-end requirements analysis, technical definition and implementation.

04

Combined manual and automated testing so developers could validate CAN-related functionality and delivery quality.

Result

Reduced the long-term maintenance burden while preserving the performance-monitoring workflow.

Helped users identify whether engines were operating optimally, supporting longer service life and lower fuel costs.

Extended a successful three-year maintenance relationship into a second product-development project.
