Conclusion
An examination of the five Domains of Instructional Technology reveals that the Instructional Designer is responsible for planning and guiding the instructional design and development of an instructional project from beginning to end. He must not only be versed in the instructional aspects, learning theories and strategies, task analysis and sequencing, etc., but also in the management aspects, making sure the right people and resources are allotted and available at the needed time and place. The instructional designer is usually working in more than one domain simultaneously. It is the mastery of all the domains that allows the Instructional Designer to produce instruction that fills the identified needs.
