An Optimal-Stopping Account of When Staff Leave the Internal Wiki to Ask Someone
A research poster from the School of Continuous Improvement fits a sequential search model with learned beliefs to 3,118 logged help-seeking episodes from 212 staff at an engineering consultancy, treating each choice between one more internal wiki query and a message to a colleague as a stopping decision. Staff typically switch after two failed queries, and when a mid-study re-index raised per-query success from 0.31 to 0.44 the switch point barely moved: the fitted model attributes this to slowly updating beliefs about the wiki, and implies roughly ten weeks for those beliefs to close half the gap.
