MotivationMotivation

In the development of local and distributed information systems, roles and goals are two important factors. Roles can be used to identify the objectives of

the system, and express the preferential requirements of users.

Goals provide a way for describing business processes at a higher abstraction level.

Effective management of roles and goals contributes to describing users intention and reusing information resources with greater granularity.

Definitions from wikipediaDefinitions from wikipedia

A role or a social role is a set of connected behaviors, rights and obligations as conceptualized by actors in a social situation. It is an expected behavior in a given individual social status and social position.

A goal or objective is a projected state of affairs that a person or a system plans or intends to achieve—a personal or organizational desired end-point in some sort of assumed development.

Definitions in MFI-8Definitions in MFI-8

• A role is abstract characterizations of organizational behaviours and responsibilities within specified organizational context.

• Description of roles will be helpful in characterizing goals in a more complete and correct way.

• A goal is a descriptive statement of business intent of a user or an organization, and it can be viewed as an objective that the business system under consideration should achieve.
