| ANALYSIS is the first and most important step in the ADDIE model. It is where the problem is defined and identified for the purpose of instruction. The analysis phase is the data gathering element in ISD that provides the pertinent information and material that will be used throughout the process. It is often the most neglected phase however, it is the most critical phase of the process. |
| DESIGN in the ADDIE model is the blueprint stage. Its purpose is to increase the value of of current instruction and transform the relevant content by preparing instructional objectives, developing evaluation tasks, sequencing the course and create an instructional model that will determine the content of instructional materials, tests, and methods that need to be developed. |


| DEVELOPMENT in the ADDIE model coordinates and communicates with other curriculum development professionals, faculty, content developers, and instructional designers is critical. Everything from lecture notes to virtual reality is brought from design to development. In the development phase, all of the previous work takes shape to produce an observable sample product. |
| IMPLEMENTATION in the ADDIE model involves putting the final touches on the elearning course and deploying the instruction to online platforms. It is best that the training will be deployed to a test environment so that changes can be made before final production. |
EVALUATION
| EVALUATION in the ADDIE model includes Kirkpatrick’s Level 1 evaluation that measures the learners’ impression of the training and Kirkpatrick’s Level 2 evaluation which measures mastery of course objectives by learners.By following up with learners after training the use of Kirkpatrick’s Level 3 evaluation can provide useful data. |
