Lean Tool implementation in our company

• Arrangement of raw material pick up by own
vehicle
• Total Flow Management (TFM)

Roadblocks we faced and how we tackled it
No Type of Waste Issues Our action
1 Space and cleanliness
We have space constraint on ground floor
We have removed absolute material and machineries
2
Transportation of material and worker
As company has 2 different manufacturing locations, Upper Floor & Lower Floor. It is observed considerable transport of the resources (material & worker)
We have shifted first floor factory to ground floor
3
Inventory of Rs. 3.25 cr
Company keeps enormous amount inventory to support its manufacturing process. This area has considerable opportunity of improvements.
We have purchased ERP software and reduce raw material, semi-finished and finished stock
4
Over production and man-power utilisation
Separate machine shop and winding department for 4” and 6” submersible pumpsets. Hence, man-hour was wasted during off season of each product.
We have combined machine shop and winding department for 4” and 6” submersible pumpsets for utilisation of man-power in both the department even in off season.
