The ADDIE Process
The following description can be found in its entirety on the Central Educational Center website.
"ADDIE" stands for "Analyze, Design, Develop, Implement, and Evaluate." It is a decades-old business process focused on continuous improvement. SEA takes ADDIE from the world of business and applies it to the world of education.
The ADDIE model consists of the following phases:
Analysis: The process for defining desired outcomes.
Design: The process of determining how desired outcomes are to be accomplished — based on supporting system(s) needed, required resources, timetable, and budget.
Development: The process of establishing requisite system(s) and acquiring needed resources to attain desired outcomes.
Implementation: The process of implementing design and development plans within the real-world environment.
Evaluation: The process of measuring the effectiveness and efficiency of the implemented system and using collected data as opportunities for improvement in closing gaps between actual and desired outcomes.

The ADDIE process provided the roadmap that was used to plan, implement, continuously evaluate and improve the Central Educational Center (CEC). It is systematic in that each stage is reliant on the successful completion of the previous stage. It is intuitive in that an organization must establish its objectives, design a plan for how it is going to achieve these objectives, fulfill the plan through development of the necessary infrastructure, personnel, and resources to accomplish the stated objectives, implement the plan as designed and developed, and then evaluate the implementation looking for ways to continuously improve by closing gaps between the initial design objectives and the actual implementation.
In the vernacular of Joe Harless and his book “The Eden Conspiracy,” concrete objectives are stated in the form of Accomplishments, which are actual ends-based outcomes (i.e. steering committee representing major stakeholders) and not process oriented means (i.e. form a steering committee representing major stakeholders). A corresponding list of accomplishments will be provided to you as a checklist for successfully creating a CEC-like school in your district. It is critical that these accomplishments be met in each stage of the process before proceeding to the next stage.
