In a complex operation there is a great risk that the desire for perfection will become your worst enemy. A desire for perfection can cause improvement work to become paralyzed by the difficulties that the organization faces. Simplifying things is the key to getting around this problem.
The core of any operation is the interaction between products and processes. Through analyzing this interaction it is possible to find ways of simplifying things and making it easier to become more efficient and gain control over the flow. For example, Part Development can help you to identify product families, or products that are similar from a manufacturing perspective, even though they may not necessarily be similar in appearance. Correct identification of product families makes the next stage of achieving flow efficiency much easier.
