IT architecture sketching
Default set
Why
Defining the IT architecture is complex and requires contributions from and interactions between software designers and/or architects. Sketching facilitates these discussions.
How
Come together around a whiteboard and draw the high-level architecture based upon discussion before and during the drawing process. Stay away from details, unless they are important for the overall design.
Practice
Most companies use architecture sketching at the beginning of the design process, and as a kick-off for major changes to a part of the architecture.
Ingredients
- The appropriate people (3–5 people with the required expertise is ideal).
- An understanding of the top-level requirements before starting.
- A whiteboard and markers.
- A camera to photograph the resulting sketch to detail later.
