From Productivity to Prosperity: The Role of Lean Thinking in an AI Age
1. The Productivity Paradox Is Back (and Bigger)
Set the scene:
- AI adoption is accelerating faster than any previous technology wave
- Investment is high, expectations are huge
- Yet many organisations are not seeing productivity gains
Introduce the paradox:
“We have more tools, more data, and more automation than ever before — yet productivity growth is flat, and work feels harder, not easier.”
Position the problem:
- This is not a technology failure
- It is a leadership and system design failure
2. Why AI Alone Does Not Create Productivity
Key argument:
- AI increases activity, not automatically value
Explore common traps:
- Automating broken processes
- Optimising local tasks while degrading end-to-end flow
- Measuring AI success by adoption rather than outcomes
Lean lens:
- Productivity is an emergent property of the system
- If the system is poorly designed, AI simply helps you fail faster
Short, punchy insight:
“AI doesn’t fix waste — it accelerates it.”
3. Redefining Productivity for the AI Era
Challenge traditional definitions:
- Output per hour is no longer sufficient
- Knowledge work behaves differently from manufacturing work
Propose a broader view:
- Flow of value
- Quality of decisions
- Speed of learning
- Reduction of failure demand
Introduce Lean AI concept:
- Lean provides the thinking discipline
- AI provides the execution leverage
4. From Productivity to Prosperity
Make the step-change:
- Productivity gains that do not translate into prosperity create risk
Explore prosperity at three levels:
- Organisational – sustainable performance, resilience, adaptability
- People – meaningful work, capability uplift, reduced cognitive load
- National (NZ/Australia) – competitiveness, inclusion, future-ready skills
Provocation:
“If AI-driven productivity only benefits shareholders and software vendors, we shouldn’t be surprised by resistance and burnout.”
5. The Leadership Shift Required
Outline the leadership challenge:
- Leaders are being asked to govern systems they don’t fully understand
Key leadership shifts:
- From efficiency to flow
- From control to learning
- From technology-first to problem-first
Lean leadership behaviours:
- Going to where work happens
- Asking better questions
- Designing systems that make good work easier
6. Why This Matters Now for NZ
Localise the argument:
- NZ productivity challenges are well documented
- SMEs dominate the economy
- AI presents a rare chance to leapfrog — if approached wisely
Risk statement:
- Copying overseas AI playbooks without system thinking will deepen gaps
Opportunity statement:
- NZ can model human-centred, system-led AI adoption
Lean AI for NZ: This is where my work comes in — helping organisations in New Zealand apply Lean thinking with AI to deliver real productivity gains, meaningful work for people, and sustainable prosperity.
7. A Conversation, Not a Conclusion
- These questions are not settled
- Leaders need spaces to think, not just tools to deploy
Call to action:
- Reflect before you automate
- Redesign before you digitise
- Lead before you scale
