Last week, a client said this to me, a sentence I often hear in industry: “We would like to embark on a Lean Six Sigma approach, but at the moment we cannot afford it. Cash flow is too tight.”
It is an understandable reaction. When financial pressure is high, the instinct is to cut spending and postpone projects that do not appear immediately vital.
Yet it is precisely in these periods of pressure that Lean Six Sigma can become a major strategic lever.
Why? Because in reality, Lean is not an expense, but an investment that produces visible results quickly.
In industrial companies, well-run Lean projects often make it possible to recover several tens, or even hundreds, of thousands of euros… within a few months.
Lean, a catalyst for operational performance
The Leanapproach, combined with the tools of Six Sigma, aims to eliminate waste, to reduce variability, and to smooth the production processes.
In other words: simpler, faster, more reliable, with the existing resources.
Contrary to what is sometimes imagined, launching a Lean project does not necessarily mean mobilising substantial financial resources.
It is often a matter of collective, structured, field-oriented thinking, with few material resources but a great deal of common sense.
Here is what a Lean project can deliver, even in a period of pressure:
Reduction of scrap and non-conformities
In many industrial companies, scrap and non-compliant parts represent a significant but underestimated loss.
Every time you have to scrap or rework a part:
-
You lose production time,
-
You consume material unnecessarily,
-
You tie up your teams correcting instead of producing.
A Lean workshop makes it possible to analyse the root causes of defects quickly (the 5 whysmethod, Ishikawa diagram, Pareto analysis…), and to put in place simple but effective corrective actions.
Result : lower scrap, reduced production costs, improved customer satisfaction.
Shorter lead times between order and delivery
When a company goes through a phase of cash-flow pressure, accelerating the turnover of flows becomes essential.
A Lean project allows you to analyse your value chain and to identify the steps without added value, the waiting times, the excessive intermediate stocks.
By eliminating these “mudas”, or forms of waste, you can:
-
Reduce lead time,
-
Deliver to your customers faster,
-
Invoice sooner,
-
And improve your cash flow.
In times of pressure, gaining a week of lead timesometimes means gaining a month of financial breathing space.
Reduction of material stocks
Stock is money tied up. And when cash flow is tight, every euro counts.
All too often, companies order “just in case”, for safety, and end up holding several months of raw material or components.
A Lean Six Sigma project can help you to:
-
Understand your real consumption better,
-
Analyse your demand variability,
-
Put in place the right stock level according to actual need.
The upshot: a reduction in working capital requirement, cash released, and sometimes even space gained in the workshop or the warehouse.
Doing nothing means accepting to keep on losing
The reasoning “I cannot afford to do Lean” often amounts to saying “I cannot afford to stop wasting”.
In reality, not committing to a continuous improvement approach is far riskier than devoting a few resources to it right now:
-
The losses remain invisible, but they accumulate;
-
Competitiveness slowly deteriorates;
-
Teams grow used to malfunctions that have become “normal”.
And in the meantime, your competitors are making progress.
The real risk is not getting started. It is standing still.
Lean adapts to your resources
Unlike some heavy technology projects, a Lean approach can be agile, targeted and progressive.
We support industrial SMEs and mid-caps with bespoke approaches, designed around your priorities and your constraints.
A project can start quite simply:
-
With a flash diagnostic on site (1 to 2 days),
-
With a pilot workshop on a critical line,
-
Or through action learning for your teams, to create an internal improvement dynamic.
Even with limited resources, you can initiate an operational excellence approach that will save you time, money… and often a great deal of peace of mind.
Conclusion: what if now were the right moment?
Yes, your cash flow may well be tight.
But that is precisely the point: Lean Six Sigma can be the key to giving you room to breathe again.
Do not see it as an unattainable luxury, but as a concrete lever for quickly freeing up room for manoeuvre.
Still hesitating?
I suggest a first conversation with no commitment, to identify together whether a Lean project could make the difference in your current situation.
Sometimes a simple change of perspective on your processes is enough to get the company moving again.
