"...“DesignDoc” is a formal outline of what will be developed for a course, as in an Instructional Design Document. This document can be used to map out what will be developed and is often used as an agreement of work to be done before development starts. My experience has been that every workplace has its own version, requirements, and format, but the elements are pretty consistent." -- from source: http://mvenable.wordpress.com/
Note: This is another posting from Dr. Venable's blog. Although it is from way back in 2010 the information is still quite relevant. She presents an extensive outline of the elements mentioned above. Plus she includes links to resources and reading materials that support her check list for developing Instructional Design projects. It is a good starting point for new instructional designers. and may provide new insights for more experienced instructional designers.
