Every improvement project does not necessarily make a system or product to be perfect. In fact almost impossible to say perfect. Perfection of a product varies greatly and is affected by many things, such as the level of demand for goods that are always changing; always upgrade the production machine with a new type, raw materials such as the tarpaulin material, different from many suppliers and many more things. However, six sigma project commitments is to always pursue perfection, which means reducing the defect in the process, reducing waste in production and management and make products according to customer demand.

Achieving “Zero defects” or the achievement of the lack of absence of defects and errors in the product requires a great effort involving all stakeholders in the company. To achieve product excellence there are several factors that influence it.

Human factors

Human resources within the company plays an important role in production operations, and therefore must be corrected in terms of skill, awareness, lean manufacturing, 5s awareness, and awareness of quality. Human factor is the factor contributing most to the quality of the products. Although all machines work automatically but if your machine does not have sufficient knowledge and expertise for products, lean manufacturing, machine operating skills, solve problems and take action then the final result of the product will not be perfect as expected.
