Practical relevance
Kaizen is not understood as an "action day," but as everyday routines: making work visible, using and improving standards, identifying deviations early on, analyzing causes, testing countermeasures – Plan-Do-Check/Study-Act. In addition: Gemba walks (go there, observe, ask "why?", show respect), Hansei (systematic reflection), and Kata routines (improvement and coaching Kata) to practice scientific thinking.
Typical misunderstandings
• "Kaizen = workshop/blitz" – Events can help, but Kaizen culture only develops through daily routines and PDCA.
• "Production only" – Kaizen is cross-industry and cross-functional (e.g., services, IT, HR, DevOps).
• "Small steps instead of strategy" – Kaizen does not exclude Kaikaku (radical change); the two complement each other.
• "Control instead of learning" – Kaizen requires empiricism and respect (Gemba), not micromanagement.
Relevance for organizations (why it works)
• Faster learning & lower risk through short PDCA cycles and early feedback.
• Higher flow & less waste (Muda/Muri/Mura) in the sense of TPS.
• Better quality & safety through standardization + continuous adaptation (5S, error prevention).
• Commitment: Kaizen involves all employees in improvements – not just specialists.
Practical example
A service center reduced ticket turnaround time by >30%: Daily gemba walks identified bottlenecks, teams introduced mini-experiments (PDCA) to reduce handovers, and standardized successful practices. Hansei rounds on weekends made learning points visible; the improvements were routinized in starter kata. Result: more stable lead times, less rework, higher satisfaction. (Mechanisms: PDCA/PDSA, Gemba, Hansei, Kata.)
Kaizen vs. Kaikaku (and Kakushin)
• Kaizen: continuous, incremental, culturally and routinely structured.
• Kaikaku: sudden changes (e.g., new value stream cuts, technology migration).
• Kakushin: often understood as "radical innovation."
In successful companies, Kaizen + Kaikaku work together: major changes in direction are stabilized by daily Kaizen routines.
Methodology toolkit
• PDCA/PDSA as standard learning loop; note Deming/Shewhart history.
• Gemba: "Go see, ask why, show respect." Genchi Genbutsu as a behavioral anchor.
• Hansei: reflect, reveal causes, anchor countermeasures (even in case of success).
• Toyota Kata: Improvement & coaching kata for practicing scientific thinking patterns.
• Kaizen + Lean tools: 5S, Standard Work, Andon, Kanban – use appropriately, not dogmatically.
Application in knowledge work & scaled environments
Kaizen can be seamlessly transferred to agile/DevOps contexts: short cycles, hypothesis testing, feature flags, A/B measurement, post-incident Hansei. In scaled setups (e.g., SAFe), Inspect & Adapt, IP iterations, and Flow Accelerators reflect Kaizen logic – but culture and routines determine the effect.
CALADE perspective
At CALADE, we see Kaizen as an operating system for organizational learning. Our coaches and consultants regularly apply Kaizen principles in projects and programs – whether in supporting ARTs, in lean portfolio management, or in transformation programs. They are trained in Kaizen methods such as PDCA, Kata, Gemba, and Hansei and use them as practical routines, not as buzzwords.
This way, continuous improvement does not become an event, but rather a part of everyday work that measurably accelerates results and makes organizations more resilient.
