MES Implementation for Mahindra Power Electronics
Full assembly line digitization with MES implementation — digital tracking at every station, zero bypass of critical steps, and an OEE improvement from 62% to 84%.
The Requirement
Mahindra needed a connected and controlled assembly environment for their power electronics production. Paper-based tracking and manual recording created delays, traceability issues, and difficulties in achieving consistent quality during high-mix manufacturing. They needed a full MES implementation that could handle assembly line digitization without disrupting ongoing production.
What YAFE Delivered
A complete MES implementation that digitized every station on the line. Assembly line digitization now tracks each product through the assembly process, collects real-time data, and ensures that every step is completed correctly before moving forward. The OEE improvement was immediate and measurable.

Frequently Asked Questions
What does MES implementation involve?
MES implementation involves deploying software and hardware at every workstation on the production line to digitally track each product through the assembly process. YAFE MES implementation covers system design, hardware installation, PLC and machine integration, operator training, and go-live support. A typical implementation takes 60 to 90 days from kickoff to full production use.
How does assembly line digitization improve OEE?
Assembly line digitization removes the delays and errors caused by paper-based tracking and manual data entry. When every station is connected and every action is recorded automatically, supervisors can see exactly where time is being lost. At Mahindra, assembly line digitization improved OEE from 62% to 84% by eliminating downtime caused by missing information, rework, and process deviations.
What OEE improvement can we expect from MES?
OEE improvement from MES implementation typically ranges from 15 to 25 percentage points in the first year. Mahindra achieved a 22-point OEE improvement after YAFE MES implementation. The gains come from reduced unplanned downtime, faster changeovers, fewer quality escapes, and better resource utilization.
Can MES implementation work for high-mix low-volume assembly?
Yes. YAFE MES implementation is well suited for high-mix low-volume environments like power electronics assembly. The system supports multiple product variants, configurable work instructions per variant, and flexible routing. Assembly line digitization in these environments typically delivers the highest ROI because manual tracking errors are most costly.
How does MES prevent assembly errors?
YAFE MES uses a smart rule engine that enforces the correct sequence of assembly steps. If an operator tries to skip a step or move a product forward before completing a required check, the system blocks the action and alerts the supervisor. This zero-bypass approach was a key requirement for Mahindra and is standard in every YAFE MES implementation.
What data does MES collect during assembly?
YAFE MES collects operator ID, timestamp, machine parameters, torque values, test results, material batch numbers, and quality check outcomes for every unit produced. This data is stored securely and can be retrieved instantly for warranty investigations, customer audits, or regulatory compliance. Complete traceability is a core feature of every YAFE assembly line digitization project.
