Keep It Simple: Start With a SIPOC Template

When people are new to Lean, one of the biggest pitfalls is trying to explain everything at once. A full Value Stream Map—with its timelines, metrics, and terminology—can feel overwhelming. Lean consultants often make this rookie mistake: they introduce complex tools before building a basic understanding.

Instead, start simple.

I like to use a very basic principle:

Anything you do more than once is a process — and the better you think about it once, the more time you save every next time.

To guide people through this, I ask just a few straightforward questions:

1. Where does the process start?What inputs are needed, and who provides them? (Your supplier.)
2. What are the main steps in the process?Keep the list high-level and uncomplicated.
3. What is the desired result?What output are you trying to create, and who is your customer?

With just these five elements — Supplier, Input, Process, Output, Customer — you can complete a simple SIPOC template.

This high-level process map is often more than enough to spark reflection, uncover waste, and establish clarity. For people new to Lean, a SIPOC template provides a gentle way to start thinking in processes without drowning in details.

Remember:

Simple doesn’t mean easy.

But starting with a basic SIPOC template helps people understand their work, communicate more clearly, and gradually build toward more advanced Lean tools.

Keep it simple. And stay humble.
