With the project ready for delivery, the learning environment is prepared by training the facilitators and learners, and placing all tools for full implementation (instruction).

The training of facilitators covers -- the curriculum, learning outcomes, method of delivery, and testing procedures.

Preparation of the learners includes -- preparing students for use of new tools (software or hardware), student registration (when necessary), advising students on good software use strategies, and other preparations (as determined in the Analyze Phase).

Placing all tools includes -- making sure the learning space is adequate for the curriculum tools, putting all books, manipulative kits, CD-ROMs, and software in place, and making sure any external links (e.g., Internet) are live.

In colloquial language, the implementation phase of the ADDIE model is where the "rubber hits the road." It is conceivable that a well-designed multimedia product could fail if instructors and learners are not prepared and/or the learning tools are not put into place. It is important that a solid groundwork is laid for the smooth and satisfactory implementation of any instructional materials.
