Plant Layout & Facility Planning For Lean Manufacturing

Introduction 

Facilities In Lean Mfg Strategy 

Lean Manufacturing is all about adding value and avoiding waste. Facility planning (land, buildings, equipment, furnishings) provides the physical capability to add value...

Facilities are expensive. Their lifetime is in decades. They take years to commission. By their nature, they are one of the most important strategic elements of a business enterprise. This is why facility design and the strategic thinking that should precede it are so important.

Many symptoms of inappropriate business architecture appear as layout or material handling issues.

A properly designed plant layout is an important source of competitive advantage. It can:

  • Operate At Low Cost

  • Provide Fast Delivery

  • Accommodate Frequent New Products

  • Produce Many Varied Products

  • Produce High or Low Volume Products

  • Produce At The Highest Quality Level

  • Provide Unique Services Or Features

These are examples of what Wickham Skinner called "Key Manufacturing Tasks."

A particular factory can perform one, two or perhaps three of these Key Manufacturing Tasks superbly but it can rarely do more. A factory is an engineered design and, like any engineered design it optimizes performance on some dimensions while sacrificing performance on others. It must because of technical limitations.

For example, if a facility must accommodate many new products with short life cycles it must have flexibility. This dictates a multi-purpose building with electrical, compressed air and ventilation systems that can change easily as equipment and layout change.

Conversely, a layout re-design can be the catalyst for re-structuring. A layout project, properly done, can demonstrate the need for change to an organization reluctant to tear itself apart and rebuild.

Levels of Detail help organize facility planning into manageable sub-projects. Each sub-project has a series of tasks that the design team must complete. The tasks and their sequence differ for each level.

Other pages illustrate the tasks and their sequence for each of the most common levels with a Project Plan (or process map). Next Page
