The case investigation undergoes several states in the Jones Legal Investigation Services system. The case investigation is first established when the attorney requests that an investigation be conducted. When the investigator begins to perform the various investigative techniques, the case investigation becomes active. The client-attorney can begin settlement negotiations, or the case can go to trial. Settlement negotiations may result in a settlement, or the case may have to go to trial if settlement negotiations fail. Ultimately, the case investigation is closed when the case is closed by settlement agreement or judicial verdict. Develop a behavioral state machine diagram for this situation.
