A detailed technical design must be derived from confirmed business requirements rather than created before requirements discovery. Salesforce's current Agentforce Manufacturing Professional exam guide separates these activities deliberately. The Design domain first requires the consultant to review discovery outputs and map Manufacturing capabilities into a business design, and then develop a detailed technical design document that describes the proposed solution's architecture, components, interfaces, data flows, and system interactions.

The technical design therefore follows the creation and validation of the business requirements and associated business design. At this point, the implementation team understands the required business processes, integrations, security model, source systems, forecast design, data migration needs, and Manufacturing Cloud features that must be configured.

Creating the technical document before engaging business stakeholders would risk designing architecture around assumptions rather than validated requirements. Waiting until after go-live would be equally inappropriate because the technical design is required to guide implementation, development, integration, testing, deployment, and future support.

The correct sequence is discovery and requirements definition, followed by business design and then detailed technical solution design.
