We study the performance effects of multiple control
forms in a single case company using longitudinal
Lean audit measures as approximations of the control
forms utilized in Lean. These measures are tested via an
enhanced profile deviation analysis against income statements
and other non-financial performance measures of
the value streams in the case company. All measures used
are archival data stored by the case company.
In the following sections, we present the case company,
the constructs, and the statistical techniques applied to our
dataset.
