Metrics are a funny thing. There are all kinds of units out there to measure mass, volume, length, duration, ratios, rates. And there are all kinds of ways of processing these numbers to make judgments about things like returns on investment, energy efficiency, job performance, throughputs; and determine things like status and rank. Healthcare institutions live and die by numbers every day.
We navigate this world with our senses. Our environments influence how we feel, then think and act. As a first step, think about just one of these dimensional variables, that of time. Use it to generate a whole different kind of metric- a metric of experience. Is a corridor 10 minutes long? What does it feel like to move through a space for that length of time? What if you have a sore hip or are in a wheelchair or have a young child with you? I hope that you will encounter many revelations as you move down that path.
