# Advanced Analytical Capability

While no *new infrastructure* is needed, the organization must possess the **analytical talent and tools** to perform complex statistical modeling — such as [[concept-lasso-regression-workforce|LASSO regression]] — to distill hundreds of variables (166 in the study) down to the core predictors of turnover.

**Why it's required:** Basic reporting cannot isolate the true drivers of turnover from the [[concept-operational-noise|operational noise]] of everyday scheduling variation. This capability is what makes [[action-mine-workforce-data|mining existing data]] actionable, and it complements the data prerequisite [[prereq-workforce-management-systems]].
