Business analysts identify sources of information that are needed to conduct the elicitation activity. There might be a great deal of information needed to conduct elicitation including people, systems, historical data, materials and documents. Documents could include existing system documents, relevant business rules, organizational polices, regulations, and contracts.
Supporting materials might also take the form of outputs of analysis work, such as draft versions of analysis models (see Specify and Model Requirements). Business analysts procure or develop the materials and tools needed. Additional planning for experimental elicitation might be required if novel tools, equipment, or techniques are going to be used.
