Key Considerations Before Consulting a Domain Expert

Domain experts are indeed people with high qualifications and stature, but they should not be trusted blindly.

Because the domain expert has highly specialized knowledge in some particular field, thus it becomes risky when dealing with a broader system. While John may be a subject matter expert and understand how a particular software works, he may not know how this software will interact with newer software with more advanced technology.

A domain expert in programming may not understand how to satisfy the needs of the client. When you ask for his help he may suggest ways that are completely irrelevant from a customer point of view.

So it becomes important that businesses know when to use the highly specialized skills of a domain expert.
