The ADDIE Model is a process which is usually used by instructional training developers and designers. There are 5 main phases within this process, the first stage is the analysis stage in which the instructional objectives and goals are established, the learner’s skills and knowledge are identified and also the learning environment. 

The second stage is the design stage; in which the content, assessment instruments, learning objectives, lesson planning and media selection are included. This stage looks at evaluating and developing a set number of strategies which have the target of meeting the project’s goals. 

The third stage is the development stage; This is the stage in which the content assets from the design stage are created and assembled together; programmers within this stage work together to integrate or develop technologies. In the development stage, the project gets revised (if needed) and reviewed based on the feedback given.

The fourth stage is the implementation stage; in which a procedure is developed for training the facilitators; the training should cover the method of delivery, learning outcomes, testing procedures and curriculum.

The fifth stage is the evaluation stage; the evaluation stage is consisted of two parts, summative and formative; with the formative process, the evaluation is done in each phase of the ADDIE process; on the other hand the summative evaluation is consisted of tests specifically designed for domain criterion - related referenced items and offering a feedback from the users. This model has become a model that organizations use to train their staff.
