The detailed technical design document converts approved business requirements and business design into the specific technical architecture and implementation approach that the delivery team will build.
The current Agentforce Manufacturing Professional exam guide explicitly requires a consultant to develop a detailed technical design document that outlines the proposed solution's architecture, components, interfaces, data flows, and system interactions, while ensuring alignment with business requirements and Salesforce best practices.
In practical Manufacturing Cloud terms, the document can define how Sales Agreements are configured, how forecast dimensions and measures are modeled, what DPE definitions are required, how security is implemented, which integrations connect ERP or other systems, what data is migrated, and how custom automation is designed.
A Statement of Work serves a different purpose. It establishes commercial scope, responsibilities, assumptions, schedule, and potentially cost.
Personas and user stories belong primarily to discovery and business-design activities. They explain what users need to accomplish but do not provide the detailed configuration and technical implementation specifications required by developers and administrators.
Therefore, the detailed technical design document defines how the agreed Manufacturing Cloud functionality will technically be configured and implemented.
