Use these four measures: meetings held against your named target list, the percentage of logged conversations that carry a documented next step and owner, pipeline created and advanced where a show conversation was part of the path, and revenue from show-sourced relationships over three years. In businesses with twelve-month cycles, a show that produced strong conversations in March may show almost nothing in June and a significant number the following February, so judging a show on a sixty-day window systematically undervalues it.
