System and UI Design
5. Design the Solution
During this step, the engineer determines how the application will look on the outside and how it will work internally.
This includes database design, interface screen layout, application architecture, and workflow charting. A professional developer always maps out their thoughts before coding, dramatically reducing mistakes and saving hours of future rework.
