The Macro Plant Layout Project
 The
elements of factory layout are simple; the tasks required to develop them is not.
These tasks and their sequence are remarkably similar for many projects. The scope,
resources, methods, formality and time required varies according to size and complexity, but
each task must be addressed in some way for good results.
Our methodology uses 25 standard tasks with modifications to suit particular projects. The
figure below illustrates the tasks and their sequence. This is a "Model" for structuring the
work in almost any macro-layout project..
The initial tasks (labeled "Information") plan the project and acquire basic information.
These tasks also help to gain consensus and establish a factual basis for the layout.
Process Mapping is an important tool here.
These initial tasks also begin the process of paradigm shift. The facts and information
gathered and presented are often surprising. We use them to jolt the organization out of its
complacency and tendency to "groupthink".
The second category ("Strategy") is only a single task. This is arguably the most important
task but usually the most neglected. It determines the process and organization of the business.
This is where management abandons the past and seriously re-thinks the manufacturing structure.

The third task group designs the spatial layout and associated systems. This is what most
people consider as "Plant Layout". While this task group appears complex, it is actually
straightforward-- IF the previous task groups have been well done.
This procedure produces at least several viable layouts. Each layout has advantages and
disadvantages. The final task evaluates the layout options and makes a selection.
The entire procedure can take as little as two weeks or as long as six months. The time
depends on project complexity and the strategic orientation of management.

You can find a complete explanation in Mr. Lee's book, "Facilities and Workplace Design - An
Illustrated Guide." Our seminar "Workcell Design for Lean
Manufacturing" also addresses these tasks and their execution in-depth.
How Material Handling Fits
The material handling system should integrate with the layout. We analyze the material
movement using Equivalent Flow Units and other quantitative methods. This procedure selects the
most appropriate Containers, Route Structures and Equipment.
