Research interestsDan Berry

Professor Berry conducts research in Requirements Engineering. This work focuses on gathering information from members of a client organization in order to produce coherent specifications of the requirements for a software system that the client desires. The unifying goal of this work consists in developing methods and tools that help gather the information needed to produce these requirements specifications.

Requirements Elicitation is the process of gathering information about the system to be built from whatever source is available, including the client, the users, and other stakeholders by watching the organization at work directly or via video tapes, conducting interviews, and reading organizational policy statements, requests for proposals, and other documents. It is necessary to pay attention even to stakeholders’ feelings.

Requirements Analysis is the process of refining all the elicited information into specifications by deriving what is possible from the information and validating the results with the client and users.

Among the techniques Professor Berry has studied and used are

• asking ignorant questions,

• abstraction identification,

• prototyping to requirements,

• writing user’s manuals as requirements specification,

• applying creativity enhancers to assist requirements elicitation,

• inspecting natural language requirements specifications for ambiguity, imprecision, incompleteness, incorrectness, and

• finding potentially ambiguous requirements statements as a means to generate questions to ask of clients.

He has also examined the role of emotion, values, and beliefs in the construction of innovative work realities and of the roles of the customer and the user in helping the requirements engineer to arrive at a complete set of requirements.

More recently, he has focused on empirical validation, with controlled experiments and industrial case studies of the usefulness and effectiveness of these techniques.
