Instructors thoughts:

Dick, Carey, and Carey's (2005) model demonstrates how to tackle an instructional design task systematically. Although a step by step systematic process, it takes into consideration the learners and their environments, as well as the need to constantly examine and readjust instruction to ensure improvement in the instruction itself. In contrast to the Dick and Carey model, Morrison, Ross and Kemps' (2004) model thrives on the idea of flexibility. The essential concept of this model is that any of the elements can be addressed at any time in the process, giving freedom to the designer to modify their instruction as necessary.

Instructors thoughts:

Dick, Carey, and Carey's (2005) model is detailed and enables designers to be thorough and appropriately steered through the instructional design process; however, it relies on front-end analysis, it assumes that your predictions of what will happen during the process will be correct. Being incorrect could cost a lot of time and money. Morrison, Ross and Kemps' (2004) model allows for flexibility and easy revision; however it lack a systematic, linear process.
