Are we doing what we set out to do? Is this model worth it? Developing evaluation models for shared spaces is currently a hot topic in our community. One of the factors we see that makes this process a challenge is that many centers haven’t taken the time to clarify their mission. When your lease is expiring and you’re in the process of drawing up plans for a new shared space, setting forth a mission for your space can seem like a luxury. Other centers spend too much time wordsmithing their mission statement into something lofty, inspirational, and all too often vague.
