Does the venue cater for visitors of all physical abilities? If not, can visitors still engage somehow?
Does the new experience enhance other elements of the visit, and the broader relationship with the museum?
Will the visitor have something to tell their friends, family, acquaintances or other potential visitors? Can you help them do this?
Does the experience work for single visitors and groups? Couples and tour groups? School groups?
Do visitors create a lot of noise or behave in a way that might interfere with other visitors?
Do visitors actively engage with the museum, or remain passive? Do they leave having begun a relationship with the museum?
Does your staff have the expertise for day-to-day maintenance of the technology? Is there someone on hand to tackle small problems?
Do visitors expect a calm, contemplative atmosphere? Can this be broken?
How will changes in the weather affect the experience?
