- Key Components:
- Project objectives and scope
- Business processes to be supported by the ERP
- Functional requirements (features and capabilities needed)
- Non-functional requirements (performance, security, compliance)
- Stakeholder roles and responsibilities
- Audience: Business stakeholders, project sponsors, and the implementation team.
2. Requirement Register:
- Purpose: A detailed log of all requirements gathered during the project. Acts as a central repository for tracking requirements throughout the ERP lifecycle.
- Key Components:
- Unique ID for each requirement
- Description and category (functional, non-functional, technical)
- Priority (high, medium, low)
- Status (proposed, approved, implemented, tested, etc.)
- Ownership (who requested and who is responsible)
- Audience: Project managers, business analysts, and the implementation team.
3. Fit-GAP Analysis:
- Purpose: Assesses how well the ERP system’s out-of-the-box features match the business requirements. Identifies gaps that need customization or process changes.
- Key Components:
- Fit: Requirements that the ERP system meets without modification.
- GAP: Requirements that need customization, integration with other systems, or process adjustments.
- Recommendations for handling gaps (customization, workaround, process change).
- Audience: Functional consultants, business analysts, and decision-makers.
4. FDD (Functional Design Document):

- Business rules and validations
- Integration points with other systems

5. TDD (Technical Design Document):
- Purpose: Describes the technical implementation details for the requirements specified in the FDD. Focuses on how to build the solution technically.
- Key Components:
- System architecture and data models
- Detailed specifications for customizations (code, scripts, reports)
- Database schemas and API details
- Security and compliance considerations
- Audience: Technical consultants, developers, and system architects.
Summary:
- BRD: What the business needs.
- Requirement Register: Tracks all requirements.
- Fit-GAP: Matches requirements with ERP capabilities.
- FDD: Functional solution design.
- TDD: Technical implementation plan.
