About Flow – Business Improvement Consultancy
Why Flow exists
Flow was created to help organisations and people work smarter, not harder. Too many teams are stuck in constant firefighting – dealing with backlogs, quality issues and complexity – without the time or tools to fix the underlying process.
My goal is to simplify that complexity, support your people and leave you with processes – and skills – that keep improving long after a project ends.
About Bart Siwek
I’m a Lean Six Sigma Black Belt and Continuous Improvement Specialist, passionate about helping organisations work smarter, faster and more effectively. With extensive hands‑on experience across logistics, procurement, operations and scientific research, I focus on delivering meaningful, measurable change.
I’ve led multiple improvement projects across a range of operations, achieving tangible results such as reducing turnaround times, aligning inventory levels, cutting quality issues and costs, and streamlining end‑to‑end processes. Alongside project delivery, I build internal capability by designing and delivering training and embedding Lean Academies within organisations.
To date, I’ve trained and coached over 150 professionals in Lean Six Sigma – helping them unlock their potential, build confidence in using improvement tools and lead sustainable change in their own areas.
