A "core" business process is described as the bare minimum of individual actions that must be completed in order to achieve a given degree of output consistency, regardless of hardware, software, people, resources, or performance.
Any workflow or process includes the core principle and core process which can't be ignored.
Anything can be added to make a core process more efficient once it has been developed, but nothing should be removed. When a fundamental business process specifies that particular activities must be completed in a specific order, the implementation must reflect this. In the same way, all task-specific actions must be represented in the implementation.
Depending on the size, industry, and culture of the company, the technique and strategy used to identify, derive, or construct fundamental business processes will differ. ITILĀ®, ISO/IEC20000, Lean and Six Sigma are only a few examples of established approaches and accompanying technologies for developing and enhancing corporate IT processes.
