Domain of Instructional Development

The Domain of Instructional Development is the domain in which the plans during the Design Domain are put "into action." Development involves using the chosen forms of media to create the product of instruction or training. During development, considerations for effective utilization (see "Utilization Domain") are taken into account to assure that product meets the designed specifications, and constant evaluation is done during the process and upon completion to compare the product to the plans in the Design domain, as well as to assure that the performance objectives have been met.

According to Seels and Richey, “Development is the process of translating the design specifications into physical form
(Seels and Richey, 1994)”. In other words, Instructional Development is the domain in which the decisions made in the Design
domain are put into action. Development involves a combination of Theory and Technology. Theory is utilized to design the
most effective form of training and to guide the development process. Technology is the tool by which the training is produced.
There are four types of technology in the development domain. They are: print, audiovisual, computer-based, and integrated
technologies. Deciding which forms of technology to use can depend on the timeline, materials available, learner abilities,
and the intended result.
