Note: This exercise is designed with the intent of having individuals collaborate by working together in groups.
Based on the discussion in this Chapter, work in a group (if possible) to develop collaborative models to represent approaches that ensure interoperability.
- Present your model(s) in graphic form (see for example, the methods used in direct crosswalking and cross-switching models in Figures 8-3-2 and 8-3-3).
- Where graphic models exist, try to represent the same mechanism in a different manner that still accurately conveys the principles involved.
- Attempt to design as many models as there are approaches discussed in the chapter.
Be creative and highly abstract; and, where group-work is possible, engage in lively discussion and brainstorming about possible new model designs.
