ISD process consists of five phases. The analysis phase defines
what needs to be trained. Next, an instructional design is crafted
to meet this need. Only after the design is complete are the instructional
materials developed. During development, individual and group tryouts
of the materials are conducted. Results are iteratively fed back
into design and development. Evaluation is a central feature of
ISD and is performed in each phase. The phases are:
1: Analysis - Determine if training is the appropriate
solution; if so, define training requirements.
2: Design - Define objectives, design the training program,
and select training methods and media.
3: Development - Develop all training materials in accordance
with design. Conduct pilot training classes. Refine course, as
4: Implementation - Implement training, evaluate, and
5: Evaluation - Performed during development, during
implementation, immediately after training, and six months or
more after training.
