Interservice Procedures for Instructional Systems Development :
Executive Summary and Model (Continued...)
by Robert K. Branson, Gail T. Rayner and J. Lamarr Cox

Potential Benefits of ISD

Based on a large number of successful demonstrations, there is now empirical evidence that competent use of the approach can greatly improve training in at least three distinct ways:

1. Effectiveness. Through the design and development procedures, a careful selection of what is to be trained, the measurement and evaluation of training, and the revision of the training program until it meets its objectives should greatly increase training effectiveness.

2. Efficiency. Several military applications of Ihave indicated that effective instruction can be offered in a much more time-efficient way than has been true in the past. The application of procedures to instruction in order to make it more time-efficient has paid off handsomely.

3. Costs. It is not reasonable to believe that the use of procedures will always result in lower costs. It is unrealistic to expect lower costs per student on all existing completely effective courses. However, theIprocedure does provide a systematic way of viewing costs of training and considering whether additional resources are justified in view of the output.

There have been many demonstrations that combinations of effectiveness, time-efficiency, and cost considerations have yielded impressive results, particularly when they have been considered in the context of making alternative investment decisions. Investments in technology for certain
