Development of a Methodology for Description of Functional Requirements for Systems with Structural and Case Processes for Organization "Third Season"

Organizations are always in a process of improvement. Solving this task companies use different decisions that are provided by developing IT sphere. Range of IT products is enormous. It is spreading from simple accounting applications to complex informational systems and databases. Consequently, entrepreneurs often order necessary software. Software developing process begins with gathering of customers’ requirements, documentation creation, formulation and prioritization of tasks. At this stage requirements are formalized, use cases (business-processes) for future product are described. Business-processes can be separated on two groups: structured flow of activities (if it is necessary to work with predictable situations) and response protocols for dynamic cases (if it is impossible to determine some specific process). Informational flows are constantly accelerating and growing. Due to this tendency, it is not enough to use only structured and predictable business-processes. Some tasks can change process already during its implementation and it is necessary to make decisions on the fly. Therefore, systems must maintain either structured processes, or flexible cases. And moreover, we need to create methodology that will describe both types of product usage scenarios.
