| # Model business control diagram and business cases After you review the major function BCD and Business Cases of the Enterprise Business Model, you must model the customer-specific major function BCD and business cases in DEM. The result of this step will be a customer-specific major function BCD that reflects the external agents and business functions, physical goods flow, business cases, and major and main business functions. You must perform the following activities: Customize the top level major function BCD: Delete the unused major business functions. Add customer-specific major business functions, if required. Remove unused business cases (children) linked to the major function BCD. Customize and model the business case BCDs in the DEM Repository: Customize standard business case BCDs, if required. Model additional business cases and link these cases to the major function BCD. Customize the Functional Decomposition in the DEM Repository: Remove unused major and main business functions including any variants on main function level that are not applicable to the customer’ s business. Add the customer-specific major and main business functions to the functional decomposition (EBM). All the functions, except for the EBM function must be linked to a parent function to create the correct functional decomposition. Document which BCDs and business functions are changed or added to the Repository. |
