Requirement Elicitation and Analysis
Requirement Elicitation and Analysis is a process of interacting with customers and end-users to find out about the domain requirements, what services the system should provide, and the other constrains.
It may also involve a different kinds of stockholders; end-users, managers, system engineers, test engineers, maintenance engineers, etc.
Here are the 4 main processes of requirements elicitation and analysis.
Fig: The process of requirements elicitation and analysis
1. Requirements Discovery
- It’s the process of interacting and gathering the requirements from the stakeholders about the required system.
- It can be done using some techniques, like interviews, scenarios, prototypes, etc, which help the stockholders to understand what the system will be like.
2. Requirements Classification & Organization
- It’s very important to organize the overall structure of the system.
- Putting related requirements together, and decomposing the system into sub components of related requirements.
- Then, we define the relationship between these components.
- What we do here will help us in the decision of identifying the most suitable architectural design patterns.
3. Requirements Prioritization & Negotiation
- It is concerned with prioritizing requirements and finding and resolving requirements conflicts through negotiations until you reach a situation where some of the stakeholders can compromise.
- We shouldn’t reach a situation where a stakeholder is not satisfied because his requirements are not taken into consideration.
- Prioritizing your requirements will help us later to focus on the essentials and core features of the system.
- It can be achieved by giving every piece of function a priority level.
4. Requirements Specification
- This is the last stage of the cycle.
- All formal & informal, functional and non-functional requirements are documented and made available for next phase processing.
