• What is the audience? Would the system be used by the general public or by ticket reservation staff?
• What technology limitations are there? Can any development platform be used (e.g. Windows, Linux, .Net, Java), or are options limited?
• How will the system handle venues/concert locations?
• What types of seating arrangements will venues have (e.g. general admission, reserved, sections, etc)
• How would reservation transactions work? Would special business rules need to be established (probably)? For example, what happens when two users try to reserve the same seats at a concert? Would the system need to prevent that?
• Will the system include a way to pay for tickets? How will the payment transaction be handled?
• Will the system need to restrict access to certain features or information to certain users?
• How will new events and venues be entered into the system?
• How will ticket prices be established and/or entered?
• Will the system need to be extensible? Will other developers need to use a system API to add custom features later?
• This is just the tip of the iceberg... there are many more questions to ask and answer
