Measure industrial and office separately, or the healthier desk hides the leak
A single blended conversion rate across asset classes tells you nothing you can act on.
Industrial and flex inquiries convert differently from office inquiries, which convert differently from land and investment sales. Averaged together, a strong industrial desk can mask a retail pipeline that is losing every requirement at the first reply.
Split the reporting the same way you split the business. Asset class first, county second. Travis, Williamson and Hays behave differently enough that a Round Rock warehouse inquiry and a South Congress retail inquiry should never sit in the same bucket.
Set the segments before you start optimizing anything. Retrofitting them later means rebuilding history you no longer have.
Keep the number of segments small enough to stay readable. Four or five is useful. Twenty means every cell has two inquiries in it and no conclusion is safe.
