Business requirements gathering is a significant and integral part of building an optimal solution. The appropriate business requirements gathering methods depends on the project you are working.
Let’s look at some of the well-known business requirements gathering methods.
Business requirements gathering methods
Brainstorming is a simple way to gather requirements. Subject matter experts gather in a room with project team members and start brainstorming about ideas – good, bad or indifferent. While this works for greenfield product development, the efficacy for other types of projects is questionable. There are several brainstorming techniques.
One on One Interviews
One of the easiest ways for requirement gathering is to ask the users what they need. The task of the business analysts is to help business find a solution for the problem. It is better to plan the interview, so you know what you are looking for. What you must do is first ask open-ended questions. Once the user starts talking, ask the questions that will expose the requirements.
Another great way to gather requirement is through group interviews. This technique is like one on one interview. The only difference is that in group interview more than one person is being interviewed. You can benefit from group interviews if everyone is on the same level. You must be more prepared when conducting a group interview. If the team is focused, you will gather requirement in a shorter span of time.
Questionnaires is another possible way to gather requirements. They are ideal for gathering requirements from hundreds of people in a compressed period. You must make sure the questions are structured correctly. Using open-ended questions is good.
One of the business requirements methods is having facilitated sessions. In this, you gather a group of people for a common purpose. This technique is best for gathering requirements that are common. By conducting workshops or conferences, you can gather requirement faster.
Joint Application Development
Another good technique is Joint Application Development. These are just like the facilitated sessions but with a slight difference. The session is not over until the objectives are met.
Prototyping is an easy way to gather requirements. The project team compiles the requirements and creates a clickable prototype of the product. Then the users can see the concept in action and be able to provide constructive feedback.
Use Cases are another way to define business requirements. It can be simple or complex, depending on the depth of information being sought. Many a time, teams focus on the “happy path, ” and that leads to a lot of unhappy outcomes.
