Solution Design Reference (SDR)
The document that decides the build
6 sections about 1 hr 13 min
- 01 What Is an SDR An SDR is not a list of variables. It is the design that shows how a business request becomes a report, held together by an ID that survives to sign-off.
- 02 Business Requirements Document The document that records what the business wants and refuses to say how it will be done. Requirement IDs, phases, out of scope, and real sign-off.
- 03 SDR Structure One solution, one ID, and a block of rows beneath it. The seven columns of an SDR, and why requirements rarely map one to one.
- 04 Variable Mapping The variable list, given the job it can actually do. Every slot including the empty ones, and why your copy will drift from the live one.
- 05 Developer Instructions The technical document is the SDR with eight more columns, not a second document. Rule types, data elements, and the one ordering rule that matters.
- 06 Validation and Sign-off Testing against solution IDs rather than against the site. Four statuses, dated cycles kept in the row, named owners, and how a project reaches an honest yes.
About this module
The design artifact that determines whether an implementation succeeds: requirements, structure, variable mapping, developer instructions, and sign-off.
Most implementations fail on paper long before anyone writes code. Somebody asks for a report, somebody else builds a variable, and the connection between the two lives in a conversation nobody wrote down.
The solution design reference is the document that prevents that. This module covers the whole chain: recording what the business asked for, turning each request into a numbered solution, mapping those solutions onto variables, writing instructions a developer can actually follow, and testing against them afterwards. Five workbooks come with it, filled in for a fictional retailer, so the shape is visible rather than described.
