In planning the flow sheets, the following questions should be considered:
1. Can any steps be eliminated?
2. Can any of the steps be combined?
3. Can any steps be done better in a different order?
4. Can any of the steps be simplified?
Work simplification should be included in the basic plan to the greatest degree possible. It should be a continuing
effort when the line is in operation.
Each step is listed either as a primary or as a secondary step. A primary step is one necessary for a smooth flow
of production. A secondary step is one necessary for the completion of production, but not necessary to assure an
immediate smooth flow. Secondary steps may be shunted from the main line operation into branch lines to be
returned at a point farther along the main line. The flow sheet should include a number for each step, the
personnel required, and also, the tools and materials needed. The most appropriate equipment available will be
selected and used in the operation. Improvised tools planned for use should be approved by the appropriate
commodity command. In selecting equipment, refer to TM 43-0001-47 and TM 43-0195. The number of
workers assigned to each operation should be kept at an efficient, operational minimum. Your draft flow sheet is
used as a blueprint for the layout of the operating line. Use the flow sheet to help you gain a clear picture of the
When you have completed the process flow sheet, you can start writing the draft SOP. The SOP supplements the
flow sheet by:
1. Explaining the mechanics of each step in detail.
2. Listing additional information such as special hazards and special operating methods.
3. Grouping together the steps which will be performed in one unit of the line, operating room, or bay.
Before preparing the SOP, you must know the format and the elements that make up the completed SOP. Each
non-nuclear SOP should consist of the following elements:
1. Cover Sheet.
2. Operator's Statement.
3. Supervisor's Statement.
4. Index of Operations.
5. Operations Format.
6. Line Layout.
