Why a BRD Should Precede Technical Implementation

Preparing the business requirements document for one project took more than one hundred days and reached 536 pages. The number may sound large, but that document became the foundation for product requirements, technical documentation, analysis, design, and the implementation plan.

Clear business requirements make technical delivery easier to estimate and manage. Starting with only a broad idea pushes essential questions into development, where changing workflows and processes is far more expensive.

Before implementation, define the scenarios, states, pages, problems, paths, and operations. Working through those details exposes questions that may take days to understand and phrase correctly. The market will still require changes later, but a clear foundation keeps them manageable instead of turning them into costly rebuilds.
