When planning content, interpreters need to perform a weird type of math. After they formalize their process and create their goals, they then need to edit their desires to meet the visitor desires. Getting just the right amount of content is challenging to say the least. Part of the program is that the majority of visitors use very little information, but then there are the frequent visitors need a high level of information (partly as they come frequently). Additionally, relative or power users are super keen to access information, and they are often donors. Firstly, go back to your goals documents. Tailor content needs to make sure that visitor desires are addressed in the interpretation. This is a great moment to do research. In almost every instance, museums will still deliver more content than visitors need/want. Evaluation can help organizations get better (over time) at creating the ideal amount of content.
