Even so, the LPDS will apply as a whole specifically to temporary production systems such as those used for new product development or capital facilities. The purpose of work structuring is to make work flow more reliable and quick while delivering value to the customer. Work structuring decisions are made in all project phases. For example, decisions regarding supply chain structure may be made in the project definition phase, while seemingly small details like the selection of a specific component in detailed engineering can impact how work flows within the assembly process. Production control governs execution of plans and extends throughout a project.
Production control consists of work flow control and production unit control.
Work flow control is accomplished primarily through the lookahead process. Production unit control is accomplished primarily through weekly work planning. Front end planning belongs to the project definition and design phases of projects. One of the products of front end planning is master schedules. Those purposes or functions do not require a high level of detail, which most often is inappropriate because of uncertainty regarding the future.
