Lean manufacturing is meaning by asystematic method for waste minimization which applies within a manufacturingsystem without endure the productivity. There are three type of value analysiswhich contributed from lean concept.
There are value added and non value added.The value added is an activity which adding value towards the customer. It doesmeans customer will get benefit from implementation. The non value added isvice versa from value added. In lean manufacturing, eliminating sevenwaste is something that can be done through the implementation should not beidentify and remove waste.
Based on the situation given above,the element of seven waste identified which 8 hours drying time is waste ofwaiting. Waiting time is the idle time which someone should do somethinginstead of do nothing. This is the most obvious wasted andclearly does not add value to the customer. However, not all waiting time iswasted time and did not value added. This is because waiting 8 hours of dryingtime can be identified as value added since the product will change intosomething that customer expected or demanded. Instead of waiting 8 hours, thiscompany is suggested to use automatic or robot machine to speed up the waitingtime the cars to dry. By eliminating or reducing waiting the companywill improve the productivity of the workers and it the cost can be reduced forevery expenses. While waiting for the painting to dry, the workers aresuggested to fill with the activities that can be value added in the production.
In other way to minimize the waiting time during drying process, the companyshould revise which part that consume shorter time and longer time to dry. Thepart which needed longer time should be paint first then followed by the partwhich needed shorter time. Inconclusion, all the suggestion given above is one of the way to eliminate thewaste of waiting time.
