Overview of the Phase

Review and evaluation are crucial aspects of multimedia development, and occur throughout the iterative development process rather than just at the end. At the end of each cycle of conceptualise, specify, design and produce, the product is critically examined before starting the next iteration. These processes ensure that content and the flow of interaction remain true to the original concept, that programming, for example, supports correct responses and timing and that the product meets the client/sŐ needs.

The major functions of evaluation can include: review, needs assessment, formative evaluation, effectiveness evaluation, impact evaluation and maintenance evaluation. Each of these inform the various phases of development, to a greater or lesser extent.

Formative evaluation involves the systematic collection of information at designated points in the development process. Results of alpha and beta field tests can inform content, contextual and design decisions. Summative or effectiveness evaluation, which is conducted in a more controlled environment, provides evidence that the project has achieved its intentions.

Any changes to the product are agreed to by the client and the development team.
