Procedures for Instructional Systems Development :
Executive Summary and Model (Continued...)
by Robert K. Branson, Gail T. Rayner and J. Lamarr Cox
An extremely important management function in this block is that
of insuring that the revisions made are necessary and that the data
have been carefully analyzed and interpreted before these revisions
are made.
Frequently the "easiest" solution is simply to add more materials
without adequate analyses of the problem. The manager must constantly
guard against this tendency to add material when it may not be necessary.
It will be a continuing duty of the manager, in working with those
who develop materials, to convince them of the necessity of developing
barely adequate materials in first draft form. The reason for this
requirement is that it is extremely difficult to identify materials
which have been over developed, but it is simple to identify materials
which are inadequate.
Finally, the manager must insure that the trainees used in the
validation process are truly representative of those for whom the
instruction is being designed. Revisions and adjustments in the
instruction are made on the basis of data collected from the trainees
used. If these trainees are incorrectly selected, bad revision decisions
inevitably result.
