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

procedures and techniques are too valuable to be ignored or rendered ineffective by absolute compliance to rules.

There are several principles and concepts which underlie the IPISD Model. It is these concepts, principles, and rules which define the basic intent of the Model. These are as follows:

1. The complete and full use of the management information system must be taken in order to arrive at clear data-based decisions about instruction. These decisions should range from defining what it is that is to be taught, to how it is to be taught and how it should be evaluated.

2. A sound rationale for these decisions is based on established principles of ISd. If current practices are not defensible in the context of an ISD approach, they should be seriously brought into question.

3. Basic to any systems approach model is the generation and consideration of alternative approaches and solutions to a defined problem. These alternatives should include instructional strategies, testing procedures, delivery systems, and student management systems. The selection of the optimum alternative is one principal goal of the systems approach.

4. Optimizing course effectiveness and time are basic goals of IPISD, and instructional decisions need to be made on the basis of sound cost estimates.

5. Fundamental to the IPISD process is a revision procedure which requires that any course be revised based on usage data collected internally or on follow-up data, particularly if the course has failed to meet its stated objectives.
