WRITE EITHER TASK PROCEDURE OR WORK PRACTICE Figure 7-9 shows the task procedure for operate Particle Size Monitor." Notice several features of it. (1) It starts with a statement of the purpose and importance of the task. This is included both for motivational purposes and to increase understanding and thereby retention and conformance. (2) It presents a step-by-step description of "how to proceed." (3) It expresses the steps in a positive "what to do" way rather than a long list of "don't." (4) Again, to improve understanding, retention and conformance, the reasons "why" are given for key steps. (5) It is printed in a simple, functional format. Since procedures are primarily teaching and learning tools, they must be clear, concise, correct and complete As mentioned earlier, not all tasks can or should be proceduralized. This is particularly true of tasks in the trades, crafts, maintenance and materials handling which may be done a little differently each time they are done. It is also true of tasks where the final result is what is important and how the person achieves that is pretty much left up to her or him For tasks of this nature, practices are more functional and useful.
