Gathering requirements may seem like a lot of work, unless you have the right tools at hand.

In this post we will discuss several requirements gathering techniques that you can use during software planning and development. These tools will help you make your requirements document more reader-friendly.

By no means are these requirement gathering techniques restricted to software development. You can use these tools in any other project to make requirements gathering as smooth as possible.

Requirements gathering is a crucial part of any project, large or small. It is essential to understanding and fulfilling the needs of the customers.

The process of requirement gathering include identifying and documenting the necessary requirements of customers, users, stakeholders etc. related to the project. This knowledge will be used to develop solutions in the form of products, services, software etc.

Methods used to gather this data may include techniques such as interviewing, brainstorming, focus groups, questionnaires etc.

Requirement Gathering Techniques For A Business Analyst (2021)

What is requirement gathering?

Requirement gathering is the act of generating a list of requirements to define what a project is about and its goal. You can gather insights from the stakeholders, whether they are clients, employee users, consumers or vendors. Requirement gathering often acts as the blueprints of a project. Poorly established requirements can have a negative impact, while properly established ones can lead to success.

Most often there are two types of requirements:

Requirement gathering is most often used in business, particularly around information technology (IT), and knowing about the two requirement types can help you in selecting a proper requirement gathering technique that best suites the project you are working on. For example, a business analyst hired to upgrade the software platforms of a regional health insurance company would use requirement gathering to understand the current system, how its users interact with it and what features or functions they would like to have to determine what systems are good alternatives or how to build one for team.

12 requirement gathering techniques

Each requirement gathering technique has advantages. Cost and time are important factors when picking which method to use and many times you can use more than one to ensure you gather all the relevant information needed. Here are 12 requirement gathering techniques to consider:

One-on-one interview

Introduce yourself and summarize the project, including its scope and any timelines. Build rapport with the person youre interviewing to gain their buy-in so they are more likely to give you good input. Let them know the overall topics you plan to discuss in your interview gathering session. Consider asking things like, “What is your most important business process,” or “What systems do you use, how do they work and are you satisfied with them?” Be prepared with predetermined questions. Here are some other tips to keep in mind for conducting productive interviews:

Closed-ended questions can be helpful to gain information in a short amount of time or to get details that open-ended questions are unnecessary for, like “How many online orders do customers place every day,” for example.

Group interview

Group interviews work best with interviewees of the same job position or level, as they are familiar with the topics at hand and what areas of opportunity exist. Having a time constraint also generates more urgent information sharing, like scheduling the session for only one hour versus two. Because people justify their viewpoints with supporting evidence in front of others, you can often gain deeper insights than on a one-on-one interview. Discussing each topic in a group setting also allows you to refine and clarify the requirement, which can lead to better outcomes and understanding useful to the project.

Scheduling group interviews is one challenge, since finding a time that works well for many people requires effort.

Brainstorming

Brainstorming is a common technique used early in a project because it often acts as a starting point. With brainstorming, you gather as many ideas as possible from as many people as possible to identify, categorize and assign tasks, opportunities and potential solutions quickly. Brainstorming sessions work well in group settings and it is important to take notes on generated ideas.

Focus group

A focus group is a method of market research with a set group of participants to garner feedback. The focus group can offer input about the needs, problems or opportunities to identify and create project requirements or they can validate and refine ones already brought out. The focus group participants can be employees of the client or representative of the users for this work.

Survey

Offering a survey or questionnaire allows you to collect information from many people in a relatively short amount of time, particularly helpful for interacting with people in different geographic locations and also good for budget savings and time constraints. When preparing your survey, consider these tips:

Requirement workshop

Requirement workshops are a great way to gather information and as a facilitator, it is important to be prepared for the session to go well. Gather and prepare materials and an agenda to give structure to the workshop—this helps ensure you get quality insights. Know who is attending the workshop to get the most out of it and plan better knowing what each persons expectations are. Consider meeting some attendees ahead of time to know how their personalities and work styles will integrate and to understand their views of where they see the project going.

This method often requires the most planning and preparation, and since you cant always have the right people in the room together, it is wise to run a few workshops to get the most requirement information gathering possible. It also typically takes the longest, though the quality of the information is high.

User observation

User observation is a bit like job shadow research. You spend time with a person or group of people to see how they perform their tasks in a real-life job setting. It can help you address the requirements specifically with the people in mind who will benefit from them. Some things to keep in mind when conducting user observation:

User observation is also helpful to improve a task by validating previously recorded data. Be sure to thank those who let you spend time with them. It helps build rapport and is useful if you need to observe again or connect with them for follow-up questions.

Interface analysis

Interface analysis helps create usable, effective and popular software for a client, group or consumer. With interface analysis, you review the human and artificial intelligence aspect, discovering how a person uses the system and how the system internally works. You review the how the program or software interacts with other external systems to make sure and notice any concerns that are not widely visible to users.

Document analysis

Document analysis includes reviewing the existing systems documentation, like user manuals and instructions. It is helpful particularly for any changeover risk mitigation and you can glean important information that pushes the boundary of establishing new requirements or validating existing ones. It is helpful to have multiple people review the documents and hold a meeting afterwards to compile your insights to make sure nothing gets missed.

Reverse engineering

Reverse engineering is helpful for situations lacking documentation of an existing system where you cannot perform document analysis. You can use reverse engineering to identify what a software system or platform does, though it cannot show you what a system should do or where its areas of opportunity are, so it is helpful to use this technique alongside other ones.

Prototyping

Prototyping is a newer technique used in requirement gathering. You create a prototype based on initial gathering results, like brainstorming or group interviews, to show a client an early version of a workable solution. The client can then give more requirements or refine existing ones to advance the project. This cycle of prototyping can last a few exchanges until the product meets the clients needs.

Joint application design

Joint application design (JAD) often speeds up the construction of information systems by combining group dynamics and customer involvement to come up with a solution jointly. Often led by a facilitator, each JAD participant plays a particular role in the exercise and the session requires extensive planning. The benefits of a JAD meeting include:
