You collect the needed information about the requirements by using various techniques, such as observations, interviews, questionnaires and surveys, focus groups, facilitated workshops, group creativity and decision making techniques, and prototypes. Let us take a detailed look at these tools & techniques. Even though, you might be aware of these things, there is no harm in
revising them again...
Observations
Observation is the technique in which the requirements about a product or process are gathered by directly observing the user who is going to use the product or perform the process.
Interviews, questionnaires, and surveys
An interview is typically performed by asking predetermined and on the spot questions and recording the responses of the users/stakeholders. Depending on the situation, interviews may take several forms, such as one on one, multiple interviewees, or multiple interviewers. For example, by interviewing subject matter experts and individuals who ran similar projects before, you may identify and define some features and functions of the project deliverables.
When you want to cover a large number of respondents quickly, questionnaires and surveys will be more appropriate. These are based on written sets of questions. It is always easier to have those people answer the questions in one shot than having to meet them all one by one and collecting their response.
Focus groups
A focus group is a set of prequalified stakeholders and subject matter experts that are brought together with the purpose of learning about their opinions, expectations, and attitudes about a product, service, or result that will be the output of the project. Generally speaking, a moderator facilitates the interactive discussion to make this experience more conversational than one-on-one interviews.
Facilitated workshops
A facilitated workshop is a session that brings together the cross-functional stakeholders to focus on defining product requirements. It generally proves to be an effective technique for quickly defining cross-functional requirements and reconciling differences among the stakeholders regarding the requirements. These workshops also help in developing trust and improving communication among the stakeholders and therefore fostering relationships that will help the project to succeed.
Group creativity techniques
These are group activities organized to identify project & product requirements. Some examples are:
• Affinity diagram - In this technique, a large number of ideas are classified into different groups by using some criteria. This facilitates an effective and efficient review and analysis.
• Brainstorming - This is a creative technique generally used in a group environment to gather ideas as candidates for a solution to a problem or an issue without any immediate evaluation of these ideas. The evaluation and analysis of these ideas happens later. This is one of the most widely used techniques where you let everyone come up with creative ideas and then consolidate/analyze them to choose the best suggestions. There are two specific kinds of brainstorming, which are:
o Idea/mind mapping - This is an individual brainstorming technique in which a multitude of ideas are mapped around a central or key concept in order to expose commonalities and differences among ideas and generate new consolidated ideas. Mapping also helps in classifying ideas into groups by discovering relationships among them. In addition to project management, this technique is also used in other areas, such as personal, family, and education. It helps in summarizing, clarifying, and revising ideas.
o Nominal group technique - This is the brainstorming technique with voting. The voting process is used to rank the ideas generated by brainstorming for further brainstorming or for prioritization.
• Delphi technique - This refers to an information-gathering technique used for experts to reach a consensus while sharing their ideas and preferences anonymously.
Group decision-making techniques
Group decision making is, in general, a process used to collectively assess and evaluate multiple alternatives in terms of expected outcomes. The decisions usually result in taking specific actions. This general technique can also be used to identify/generate, classify, and prioritize project requirements, including the product requirements. To reach a group decision, multiple methods are available. Some are:
• Dictatorship - One person has the authority to make the decision. While this expedites the decision making, it may not be the most effective decision-making method. This is usually because, people don't like to be told what needs to be done in a one way traffic kind of environment
• Unanimity - This is opposite of dictatorship. A decision is accepted only if everyone agrees.
• Majority - A decision must be supported by more than 50 percent of the members of the group. Like a usual election
• Plurality - The alternative supported by largest number of members wins even if this number does not make a majority. This situation arises when there are more than two alternatives. Plurality with two alternatives is simply a majority method.
Prototypes
A prototype is a working model of a product put together without developing the actual product. Organizations usually make prototypes for developing proof of concept. Prototypes can also be used to collect requirements by experimenting with the prototype and by letting stakeholders experiment with it and offer feedback. A prototype is more tangible than the abstract idea of a product. Prototypes can be improved and modified based on feedback from the stakeholders. In this way, prototypes support the progressive elaboration process of developing requirements

How is feasibility and requirement analysis related?
The first step in SDLC is to gather requirements. After gathering requirements these requirements are analysed, if all the requirements are gathered then more feasible the project will be.

What is requirements engineering?
Requirement engineering is a process in which we identification of user requirement, analysis of requirement, validation user needs, documentation of requirement.
Why requirement engineering is considered to be most important activity responsible for success of software being developed?
Requirement engineering is crucial for software development because it establishes a clear understanding of what stakeholders need, which directly influences the design and functionality of the software. By accurately gathering, analyzing, and specifying requirements, it minimizes the risks of project scope creep, misunderstandings, and costly revisions later in the development process. Effective requirement engineering ensures that the final product aligns with user expectations and business goals, ultimately contributing to the software's success.
