The Kaizen Way: what it means and how to apply it

• Kaizen is a philosophy of continuous improvement, not a standalone tool or a rigid project method. Its strength lies in small, steady changes led by the people closest to the work.
• Practices such as gemba observation and PDCA, and tools such as 5S or visual management, can support Kaizen without defining it.
• In industrial washing, this mindset can support safer processes, better hygiene and more efficient use of water, energy and detergent.

Kaizen, Japanese for "change for the better", is a management philosophy centred on continuous improvement through small changes made as part of daily work. It is not a single technique to apply to every problem. Instead, it encourages teams to observe reality, involve the people who do the work and select the most appropriate tool for each situation. Over time, these habits can reduce waste, improve quality and strengthen operational excellence.

What Kaizen is and why it matters

Kaizen is a philosophy and organisational mindset, rather than a method or toolbox. It encourages everyone to question how work is done and make practical improvements every day. Kaizen events may rely on tools such as 5S, Value Stream Mapping or PDCA

For example, on a tray-washing line, operators may notice that some items still have residues due to inconsistent loading. Rather than immediately changing the entire process, the team tests a positioning guide over a small number of cycles, compares the results and adjusts the solution. If the improvement works, they update the procedure and apply it across the remaining shifts. This combination of observation, small-scale experiments and operator involvement is what brings the Kaizen philosophy to life.

Its value comes from repetition and participation. One improvement may seem minor, but many small changes can lower defects, shorten cycle times and make work safer and easier. The lasting result is a culture in which problems become visible and the people closest to them help improve the standard.

Main advantages of Kaizen

The advantages below come from Kaizen's habits of observation, participation and incremental improvement. 

• reduce waste and unnecessary motion by removing repeated handling and placing tools, materials and information where people need them most. 
• improve quality and process stability by agreeing the best-known method, checking results and correcting small deviations before they become defects. 
• increase employee involvement and ownership by enabling operators to identify friction, test ideas and help improve the standard they use. 
• spot problems earlier by observing the process where it happens and comparing actual conditions with the expected standard. 
• support operational excellence without heavy disruption through small, low-risk improvements and rapid learning. 

How to make Kaizen part of daily work

You can make Kaizen part of your team through simple routines, including setting time aside to analyze and improve your work. Whatever you sit on the org chart, here are some tips to get started.

Observe the work at the gemba

Go to the place where the work happens, watch the process and speak with the people involved. Genchi Genbutsu - going to see the actual situation - prevents improvement from being based only on reports or assumptions.

Invite teams to surface friction

Create a simple routine for operators to raise recurring delays, awkward movements, quality risks or rework. Short daily conversations, Quality Circles or Kaizen Groups can turn their experience into improvement ideas without waiting for a formal project.

Improve one point at a time

Select a small issue that matters, try a low-risk change and observe the effect. PDCA can structure the experiment when useful, but it supports the Kaizen mindset rather than replacing it.

On a tray-washing line, for example, operators may notice residue caused by inconsistent loading angles. They could test a positioning guide on one load, check rework and cycle stability, then refine the idea before extending it.

Use the right tool for the job

Do not treat every issue as a nail for the same hammer. Use 5S for workplace organisation, a Spaghetti Diagram for unnecessary movement, Value Stream Mapping for end-to-end flow, Poka-Yoke for error prevention or Kanban for pull and replenishment. Begin with the problem, not the tool.

Make abnormalities visible

Use clear standards and visual signals only where they help people distinguish normal from abnormal conditions. An Andon, red tag, dashboard or simple workstation cue should make action easier, not add administration.

Turn useful learning into the new standard

When an improvement proves useful, update the SOP or create a One Point Lesson, train the relevant people and confirm that the new method works in different shifts. If the test fails, keep the learning and adjust the idea.

Keep improvement alive every day

Managers should make time for observation, remove obstacles and recognise participation. Teams should revisit standards and unresolved problems regularly. Focused Kaizen events can accelerate a larger change, but they should reinforce - not replace - daily improvement.

Improve your operations with MultiWasher

At Somengil, applying a Kaizen mindset does not mean buying one machine or using one improvement tool. It means observing the washing process, involving operators and improving the points that affect hygiene, safety, flow and resource use.

MultiWasher can support that work when the current process reveals inconsistent results, excessive manual handling or avoidable use of water, energy and detergent. Its repeatable cycles make performance easier to standardize and monitor. The equipment is therefore an enabler of a better process - not Kaizen in itself.

FAQ on the Kaizen Way

Here are a few quick answers to the questions readers ask most often about Kaizen and its use in industrial washing.

What does Kaizen mean?

Kaizen means “change for the better.” It refers to continuous, incremental improvement in daily work.

Is Kaizen the same as 5S, PDCA or Lean Six Sigma?

No. Kaizen is the philosophy of continuous improvement. 5S, PDCA and other approaches can support it, while DMAIC is a structured improvement method commonly used in Six Sigma.

Is Kaizen only for manufacturing?

No. It is widely used in manufacturing, but it also works in logistics, healthcare, food production, and other operational settings.

What is the role of PDCA in Kaizen?

PDCA is not Kaizen itself. It is a simple cycle teams can use to test an improvement, check its effect and adjust or standardize what they learn.
