Elicitation of needs is a set of activities aimed at finding the needs of a system through communication with customers, system users and other parties who have an interest in system development (Sommerville & Sawyer)
Elicitation of needs is something that is made from the obtained (Dorfman & Thayer)
ELISITATION CYCLE NEEDS
The figure below is an illustration of the elicitation process model and analyst in general. The activities described in the model are illustrated as a spiral in which the process goes from the inner ring to the outer ring of the spiral.
This Needs Discovery is the process of interacting with system stakeholders to collect their needs. The realm of needs from stakeholders and documentation were also obtained during this activity.
- Grouping and organizing needs. This activity collects needs that are not yet structured, groups needs that are interrelated, and then organizes them into coherent groups.
- Priority and negotiation of needs. In this stage, the management activity carried out is a risk analysis of each need, which includes risk assessment and identification of controls that can be applied to reduce the risk of each need.
-Documentation of needs. In this stage, management activities carried out are validation and system development.
ELISITATION MODEL: WIN-WIN SPIRAL
• Introduced by Boehm et al. (1998)
• Emphasizing the activity of gathering needs and the importance of intensive stakeholder interaction
• Minimizing formal processes = non-functional requirements play a very important role in the system requirements specification process
This model is initialized by identifying stakeholders and determining the winning conditions of each of these stakeholders. Then the engineer needs to detect every possible conflict arising from these conditions and direct the stakeholders involved in the conflict to find a resolution, both through negotiation and compromise. From the results of this process came the system specifications, which are non-conflicting win conditions and the results of the compromise. Finally, after the stakeholders agree or agree on the specifications that have been built together, the process is concluded. From there then the new iteration starts again.
ELISITATION MODEL: I * FRAME
• Introduced by Yu (1997)
• I * Frame has two main components, namely the strategic dependency model (Strategic Dependency Model) and the strategic rational model (Strategic Rationale Model)
• The strategic dependency model represents a number of interdependencies between actors in an organizational context.
• The rational strategic model represents the needs and concerns of stakeholders.
