Eliciting non-functional requirements is an integral part of the business analysis process. These requirements define the characteristics, attributes, and constraints of an application that are not related to its functionality. Non-functional requirements can include performance, usability, security, reliability, and scalability.
The process of eliciting non-functional requirements can be a challenging task, but it is critical for determining the overall success of a project. Business Analysts can employ a variety of techniques to elicit non-functional requirements from stakeholders effectively.
One of the most effective ways to elicit non-functional requirements is by conducting interviews. During the interview process, the Business Analyst can ask open-ended questions to identify what stakeholders think are the critical non-functional requirements of the project. This approach can help stakeholders feel more invested in the process, and it enables them to communicate their needs better.
Another valuable technique is to conduct surveys. Surveys enable Business Analysts to reach a broader audience and gather feedback on non-functional requirements that may not have been previously identified. A survey can be used to gather information about stakeholder preferences, priorities, and constraints.
Prototyping is also an effective approach to elicit non-functional requirements. By creating working models of the application, Business Analysts can analyze its performance and usability. This process allows them to identify the non-functional requirements that must be addressed to improve overall functionality.
In addition to these techniques, Business Analysts should consider using use-cases, scenarios, and user stories to elicit non-functional requirements. Each technique can help to identify different types of non-functional requirements, enabling the Business Analyst to create a more comprehensive requirements document.
In conclusion, eliciting non-functional requirements is a critical part of business analysis. Effective elicitation techniques like conducting interviews, surveys, prototyping, use cases, scenarios, and user stories can help Business Analysts to gather the necessary information required to define a comprehensive set of non-functional requirements. By investing time and effort into the elicitation process, Business Analysts can ensure that the project is successful by meeting stakeholder needs and expectations.
