One of the effective ways of requirement gathering is by way of questionnaires. In this type of requirement gathering, a consultant prepares a list of questions which can be asked to various groups of people to get the maximum information from them. This type of requirement gathering is helpful when you want to do a requirement gathering for unknown requirements.

It has been seen that the business users are more concerned about their business challenges, and keeping this in mind, they give requirements for business intelligence. However, they may not be able to visualize what more could be done with their data set, which could help them to analyze their data in a better way. It is a consultant’s duty to help the business users understand the power of business intelligence tools like Qlik Sense by asking a series of questions which are related to their business or domain.

There is no specific type or format of questions which can be prepared to be asked. They can be optional types of questions, or they can be a questions with yes or no options, or they can be questions which require descriptive answers. Only thing to remember is that the questions should be specific and relevant to the domain for which the requirement gathering is going on; otherwise, they may not give the expected information.
