Critically examine any relevant existing instruction, information, and/or images to determine whether and how they might be used for the instructional design project. Production is usually the longest activity in the instructional design/development process and it consumes the most energy and resources. It involves both general and specific production tasks and the management of those daily activities, as well as prototype tests at critical points to ensure that the project design is on the right track, quality monitoring, and the incorporation of feedback and review comments to improve the final product. Project production almost always includes writing tasks, whether for print materials, multimedia presentations, website or online course content, or audio and video scripts. An iterative cycle of prototype production, testing, and revision based on feedback and test results – sometimes referred to as rapid prototyping or agile development – fosters a policy of continuous improvement that ultimately improves the quality and effectiveness of the final instruction.
