MotivationMotivation

Roles & Goals are essential elements in system development

Roles is used to classify and identify the actors of the system

Each role has preferential intentions, including goals

Goals provide a way to express higher level requirements

Effective management of roles & goals contributes to goals reuse by roles

Definitions in MFI-8Definitions in MFI-8

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

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

99

From: Resolution of Wuhan Meeting, September, 2008From: Resolution of Wuhan Meeting, September, 2008

Specify a metamodel for registering users’ Roles & Goals in specific domains that can be used to describe users’ intention.

Define the decomposition and constraint relationships between goals.
