Process flow - The stages overlap - a good collaborative overlapping can prevent the worst effects of the waterfall model.
Context map - The execution gets started with inputs - user interviews, business stakeholder sessions, discussions on technology, feedback from past implementations... The essence of this is captured in a context map, which shows all the key elements of the scenario, and how they interrelate.
Task flow analysis - For complicated architectures and large teams, you might spend a significant amount of time documenting the task flows in a way that makes them easy to understand and communicate.
High-level IA - And now you move magically from Analysis to Synthesis – reassembly of all the fragments into a brand-new, coherent, logical whole. This is the core concept (or "architecture") around which the details will be built.
Brainstorming wireframes - And individual wireframes plot out key screens in the task flows. Shown here is a sketching stage before the final composition on software of choice.
