Almost all subjects can be developed by using a logical sequence based on time, space, or special topics. In the time sequence, for instance, you might consider your subject under the three categories of past, present, and future, or you might begin at a certain date and move backward or forward from that date. All process talks, for example, should begin at the raw-material stage and move through the various manufacturing steps that produce the finished product. How much detail you bring in will, of course, be governed by the time you have.
