Notice in the diagram that the model is a continuous circle, with no specific beginning point, meaning that the nine elements are mutually supporting. This model suggests a less rigid approach to the instructional design process, allowing the experienced designer to use personal judgment regarding where to begin the process and which steps are necessary to solve the instructional problem. The steps may be performed in any order either independently or simultaneously at the discretion of the designer . The interaction between the steps makes this model a good choice for a project where multiple team members are working together to complete the instruction.
