PT. Sumbiri boosts productivity by 13% with GSDCost

The Challenges

1. Limited Method Standardisation

In the absence of standardised and optimised manufacturing methods, PT Sumbiri were faced with significant variation in the time taken to produce garments, between operators and across lines and factories. This variability in method and time resulted in lost efficiency, variation in the quality due to increased defects, and made accurate production planning a real challenge.

2. Inaccurate Standard Times

Without a scientific approach to standardising manufacturing methods, it was a tough task to establish an accurate standard time for the production of any given style. Prior to the implementation of GSDCost in the factory, PT. Sumbiri relied on traditional and manual method-time measurement which was time consuming and resulted in unreliable and subjective estimates. As a result, PT. Sumbiri were having to make business-critical decisions based on inaccurate and unreliable data, affecting production capacity, line balancing, efficiency, product costing, delivery commitments and ultimately, business profitability.

The Solution

The introduction of GSDCost allowed PT. Sumbiri to create accurate method standard for production to help them establish and optimise international standard time benchmarks and accurate SMVs, providing the foundation to optimise processes, driving increased factory efficiency and productivity. The standard motion codes and pre-determined times used in manufacturing resulted in increased efficiency through better line balancing, capacity planning and improved quality.

Furthermore, GSDCost also proved to be an effective tool for PT. Sumbiri to arrive at fact-based and optimal garment costing, eliminating the subjectivity in the process and the chances of over/under costing.
