Draft outline details
Step by step
- Start from the approved option and the requirements: write purpose, scope, and the three constraints that shape everything.
- Draw the context view with stores, web, mobile, ERP, CRM, payments, carriers; write one line per external link.
- Draw the container view and list the five biggest decisions, each with a reason and a link to an ADR.
- Planned mistake: include table schemas and class names in the HLD "for completeness". Fix: move them to the LLD, leave a reference, and show how the HLD shrinks to a reviewable length.
- Write the quality attribute table: target, design element, how it will be evidenced.
- List risks and open questions with owners and read the finished HLD as a reviewer would.
