How Production Efficiency Was Improved by 50% in a Transformer Manufacturing Plant – E-VS-01

The production team studied the actual work being carried out on the shop floor.

The time required for different activities was measured. Delays, unnecessary movement, waiting time and inefficient work sequences were identified.

The production process was then reorganised.

Some activities were rearranged, some unnecessary steps were removed and available resources were better balanced.

The result was an approximately 50% improvement in production efficiency.

The important lesson was that a large improvement did not always require a large investment.

The factory had experienced production delays and differences in the time taken to complete similar activities.

Instead of immediately adding manpower or equipment, the production process itself was studied.

The objective was simple:

Find where time was being lost and make the work flow better.

The main problems were:

Production was taking longer than necessary

Some activities were creating delays for other activities

Work was not evenly balanced

Actual process times were not clearly understood

Manpower and resources were not being used as efficiently as possible

1. Observe the actual work

The production process was studied directly on the shop floor.

2. Measure the time

Time studies were used to understand how long different activities actually took.

3. Find the delays

Activities causing waiting, unnecessary movement and process interruptions were identified.

4. Rearrange the work

The sequence of activities was changed wherever a better flow was possible.

5. Improve resource utilisation

Manpower and production resources were better matched with the actual work requirements.

6. Monitor the improvement

Production performance was reviewed after implementation to ensure that the improvement was sustained.

The improvement delivered:

Approximately 50% higher production efficiency

Better use of existing manpower

Smoother production flow

Less unnecessary waiting and movement

Better understanding of actual production times

Improved production discipline

The real benefit

The biggest lesson was simple:

Before investing in additional resources, understand where the existing resources are losing time.

This case is useful for production managers and plant heads facing:

Low production output

Long manufacturing times

Bottlenecks

Poor manpower utilisation

Uneven workloads

Repeated production delays
