Currently there is considerable interest in "re-engineered" institutions in developing performance measures - both effectiveness and efficiency. Performance measures however only have meaning when they are measured against a standard. While professional museum practises are well known and well articulated, there is less assurance even in Australia, New Zealand or Britain, as to what might be appropriate benchmarks against which performance might be measured. For example at some museums, performance could be measured by increase in knowledge gained after viewing an exhibit. All well and good but what would be the benchmark - a 5% 10% or 20% gain. I will be contacting the Benchmark Institute in Texas for their ideas but I am interested in any benchmarking exercise that museums might have undertaken in the last while.
