Agile Software Development isn't focused on the business or application but on making the customer/user "happy". This is its fatal flaw.
Any project should be based on a process model. In the case of a business, the Business Model is a broad range of informal and formal descriptions to represent core aspects of the business, including purpose, offerings, strategies, infrastructure, organizational structures, trading practices, and operational processes and policies.
A business model is the method of doing business by which a company can sustain itself. That is, generate revenue. The business model spells-out how a company makes money by specifying where it is positioned in the value chain of its market(s).
A business process is a collection of related, structured activities or tasks that produce a specific service or product (serve a particular goal) for a particular customer or customers. There are three main types of business processes:
1. Management processes, the processes that govern the operation of a system. Typical management processes include "Corporate Governance" and "Strategic Management".
2. Operational processes, processes that constitute the core business and create the primary value stream. Typical operational processes are Purchasing, Manufacturing, Marketing, and Sales.
3. Supporting processes, which support the core processes. Examples include Accounting, Recruitment, Technical support.
A business process can be decomposed into several sub-processes, which have their own attributes, but also contribute to achieving the goal of the over-all business process. The analysis of business processes typically includes the mapping of processes and sub-processes down to activity level.
A business process model is a model of one or more business processes, and defines the ways in which operations are carried out to accomplish the intended objectives of an organization. Such a model remains an abstraction and depends on the intended use of the model. It can describe the workflow or the integration between business processes. It can be constructed in multiple levels.
A workflow is a depiction of a sequence of operations, declared as work of a person, work of a simple or complex mechanism, work of a group of persons, work of an organization of staff, or machines. Workflow may be seen as any abstraction of real work, segregated into work shares or units, work components and their process and/or order of assembly. For control purposes, workflow may be a view of the methods of real work employed to complete them.
