Stakeholders may include customers, business people also technical people who all contribute to the Development of software.

Requirements are of utmost importance from any software application development perspective.

If at any point during application development if any requirement fails to get clarity, then that can cause many major effects on the application.

  4. Interviews – Group of stakeholders will discuss and come up with understanding of requirements.
  5. Observations – This is a process of observing a stakeholder in terms of business process and understanding the requirements.
  6. Prototyping – Creation of the application screens using prototyping tools which would help understand stakeholders about the visual representation of the software application which is under development or yet to start development.
  7. Requirement Workshop – In this method of requirement elicitation formal discussion is held for understanding of requirements.

Survey – Survey is a requirement elicitation method for collecting feedback about the requirements in terms of questionnaire. Survey is completed by stakeholders and accordingly requirements are collected.
