•space usage
•student satisfaction
•external visitors to the library

WHAT? WHO?WHY? HOW?
• CURIOSITY: Ask questions! • Be wary of the “Streetlight Effect”:
• resist tendency to look for answers where it is easiest to find information and data (akin to looking for keys only under the street lamp)
• focus on asking the right questions & finding new ways to expose and analyse the data that can lead to the answers (& to help improve and refine the questions themselves)
