Evaluating Storage Tank Cap 10000L Manufacturer by Using Lean Project Management

摘要

Business competitions between manufacturing fabrication industries increase fiercely. Companies were demanded to produce high quality products with competitive price that can be delivered to the consumer on time. Storage tank (10000 liter capacity) is one of the most ordered item but most of the time the delivery is unpunctual. During the initial planning, buffer time was unavailable, which caused 32% cost increase by waste. In this study, the concept between lean manufacture and lean project management was bridged to obtain minimal delay. The first research methodology was to identify and analyze waste, second method was risk analysis by FMEA, and final method was cost and time estimation by critical chain project management. S Curve depicted the decrease of delay, and value stream mapping was used to map optimum result from lean project management. Potential waste was "waiting", and the highest FMEA risk value was material delay caused by weather conditions. Project buffer result shows 39% decrease in engineering task and the actual cost was still within the budget. The company need to integrate HR cost in the project and measure the time buffer to predict delay gap.
