Why is mapping a process essential before attempting to improve it, and what tools are commonly used?
Before improving a process, it's essential to visually map it out—to truly understand its current structure, inputs, outputs, and interactions. This practice is known as process mapping, and it's a critical first step in identifying inefficiencies.
Benefits of process mapping:
Creates Clarity:
Everyone sees the same version of the process, reducing misunderstandings.
Identifies Waste and Redundancies:
Mapping reveals unnecessary steps, bottlenecks, delays, and rework loops.
Supports Communication:
A visual map aids collaboration across teams, departments, or external stakeholders.
Forms the Baseline:
You can’t measure improvement if you don’t know the starting point. The “as-is” map helps compare “before and after” performance.
Common tools used:
Flowcharts (simple and visual for basic processes)
Swimlane Diagrams (shows responsibilities across functions)
Value Stream Mapping (used in Lean to highlight value-added vs. non-value-added steps)
BPMN Tools like Lucidchart, Bizagi, or Microsoft Visio
Ultimately, mapping is a diagnostic step—like taking an X-ray before surgery. It allows process improvement teams to focus their efforts where they matter most.
