Find the bottlenecks in your processes. Enter cycle time, wait time, rework rate and handoff delays to calculate your workflow efficiency score and the annual cost of process waste.
In most business processes, only 20-40% of the total cycle time is spent on value-adding work. The rest is waiting (approval queues, dependency delays, information gaps), rework (fixing errors from unclear requirements or poor handoffs), and administrative overhead (status updates, progress chasing, reporting). Lean and Six Sigma methodologies address these wastes — but you first need to measure them.
Waiting (approval queues, blocked dependencies), rework (fixing errors that correct requirements or better handoffs would prevent), over-processing (gold-plating work beyond what the customer needs), defects (output errors that require correction downstream). These four typically account for 70-80% of process waste in knowledge work environments.
Single biggest efficiency improvement in most knowledge work processes: eliminate approval steps that add no value (every approval step must justify itself). Second: define "done" clearly before work begins to prevent rework from unclear requirements. Third: reduce handoff points — each handoff adds queue time and loses context. Each of these changes can improve efficiency by 10-20 percentage points.
Process efficiency (or value-add ratio) = Value-Adding Time / Total Cycle Time × 100. Value-adding time is the time actually spent transforming the output in ways the customer values — not waiting, approving, checking, reworking or reporting. Most business processes have 20-40% efficiency. World-class lean processes achieve 60-80%. Measure by mapping every step in the process and classifying each as: value-adding, business-necessary (non-value-adding but required), or pure waste.
