I think, we have to talk about the importance of achieving the synergy between BizArch and BPM (trio of discipline, tools and architecture practice).
BizArch brings the context – business strategy, business priorities, chain of business goals, business metrics, business reports, org. structure, governance structure, etc. BPM brings the power of explicit and executable processes (which are used for various purposes: modelling, automation, execution, control, measurement and optimisation).
Correct and joint usage of BizArch and BPM enables:
1) direct (or explicit) execution of the business as the same model of work is used by top management, line managers, ordinary workers and implementation teams
2) better management by proactive control of process execution
3) better capacity planning by implementing capabilities via processes
4) better customer experience by fitting internal business processes to customer’s business processes (the latter maybe be implicit some times).
