Obeya or Oobeya refers to a form of project management and is a component of lean manufacturing. Even more specifically, the Toyota Production System. The obeya is a similar concept to a "bridge room" or a "war room."
During the product and process development, all individuals involved in managerial planning meet in Obeya to speed communication and decision-making. This is intended to reduce "departmental thinking" and improve other methods of communication which tend to introduce forms of waste into the process.
Conceptually akin to traditional “war rooms,” an Obeya will contain: visually engaging charts, graphs, milestones, progress, countermeasures and any other forms of critical information for attendees to make decisions accurately and efficiently.

Overall equipment effectiveness is a metric that helps measure and track the performance of finite resources and can help companies highlight opportunities for improvements. The results are stated in a generic form which allows comparison between manufacturing units in differing industries. It is not however an absolute measure and is best used to identify scope for process performance improvement, and how to get the improvement. If for example the cycle time is reduced, the OEE will increase i.e. more product is produced for less resource. Another example is if one enterprise serves a high volume, low variety market, and another enterprise serves a low volume, high variety market. More changeovers (set-ups) will lower the OEE in comparison, but if the product is sold at a premium, there could be more margin with a lower OEE.OEE measurement is also commonly used as a key performance indicator (KPI) in conjunction with lean manufacturing efforts to provide an indicator of success. OEE can be illustrated by a brief discussion of the six metrics that comprise the system. The hierarchy consists of two top-level measures and four underlying measures.

One piece flow is the ideal concept behind the just-in-time system. One-piece flow is when items or services are processed in one piece lot sizes moving directly from one process step to the next (one piece at a time). One-piece flow drastically reduces lead times and improves quality by exposing abnormalities in processes.
The output is the result of a process being applied to an input. It can be in the form of energy, work, goods, services or activities. The output is the result whether desired or undesired the output is simply the result of a process or function being applied to the input. Y=F(X) + ε, the Y is the output.
Overproduction is one of the 8 major forms of waste. It occurs when parts or services are created in excess of the needed demand or when services and products are created/delivered in advance of the needed schedule.

Overproduction is considered to be the deadliest waste of all forms of waste. Why in your opinion is this form of waste so "deadly?"
