In order to create the best possible solution to a design problem, taking an informed approach is imperative. The IRED model below provides guidance as to what kinds of information is needed at different design stages--the generic design stages are on the left side of the model, and the information activities on the right.
| Engineering Design Activity | Information Activity |
|---|---|
| Organize the Team | Develop knowledge management strategy |
| Clarify the Task | Provide context |
| Synthesize potential solutions | Investigate prior work |
| Select best solution | Assess technologies/approaches |
| Refine preferred solution | Assemble detailed technical information |
| Communicate to inform and persuade stakeholders | Distill and translate project knowledge |
