Full "Vision" support  (Motivation, Strategy)

The procedures related to large systems architectures (TOGAF, UPDM, ...) require a phase of "vision" based on goals, risk analysis, and analysis of the area, prior to the requirements phase. Web Analyst integrates support of these elements for a wider coverage and more comprehensive traceability.

The support of Vision elements strengthens requirements analysis, providing means of justification and requirements discovery.

For example, in the diagram below, we can see that the requirement (IS access via website) guarantees the satisfaction of a company's goal.

Generally, goals, risks and business rules are elements that can be broken down into requirements for the system in question. The terms reinforce the overall consistency.

Goals

goal

The governance of the information system first consists of setting company strategy related goals related to the information system. This approach defines how the information system contributes to creating value.

Risks

risk

The risk is combination of a hazard, its probability, severity and acceptability. Risk analysis allows to derive requirements and / or goals, to identify risk scenarios, to locate the involved components, to clarify the consequences. Traceability facilitates the management of risks and the definition of a system that integrates them.

Terms

term

The development of a glossary (set of terms) clarifies a business area. The presence of ambiguities, vagueness of the domain concepts is a major embarrassment for practitioners in the field, and results in erroneous interpretations for analysts, architects and developers of the system. Establishing a glossary is an exercise that does not require any technical skill (but domain knowledge). Its implementation in Modelio allows to trace model elements, to have a consistent model, measure the domain coverage, and get clear and unambiguous documentation.

Business Rules

businessrule

Business rules are structured high-level statements that can coerce, control and influence one aspect of the business. As these can decrease or increase the impact of risk, and still make rational decisions. A business rule can influence decision making. The goal is to have clear rules, that is to say, unambiguous and understandable by all, especially by non-IT. The computer systems are based on business rules to automate processes.
