OUR VISION is to be the highest quality and most reliable partner for our clients on their lean journey to become the most efficient and effective competitors in their industries.
Our mission is to help our clients quickly implement flexible and sustainable lean processes, organizations, products and services and to continually improve their performance.
Overview
Distilled from the ground-breaking business philosophy that set Toyota on the path to global success, Lean Management is far more than a management consultancy toolkit. Instead, it is a profound change of corporate culture, from the bottom of your organisation to the top, that perceives value from the customer’s perspective and gears everything you do towards optimising that value. It is the foundation of a long-term process of continuous improvement that will transform your business.
Developed in the automotive world, the beauty of Toyota Way (トヨタウェイ) is that it applies equally well across all business sectors. Reducing lead time, supply chain management, improving quality, cutting costs and enhancing the motivation of your people… every change that Lean brings about must satisfy one key criterion: it must benefit the customer.
A Lean business model is the embodiment of our philosophy: “Kaizen. Zero waste implemented!(改善,ムダゼロ達成!) Not cost-cutting for its own sake, but the process of putting into practice long term, sustainable efficiencies that increase profitability at the same time as improving value for your customer.
You might call it a win-win. We call it Lean Management.
OUR VALUE PROPOSITION
We listen to our clients. We are trusted counsel to business leaders. We mentor and build people’s capabilities and therefore we deliver better results for our clients.
We provide tangible Lean Management Expertise (トヨタウェイ), not idle talk. We develop sustainable Lean Solutions across various industries throughout the world. We implement. We are passionate about what we do. We are Lean experts.
OUR APPROACH
Our approach is based on the basic Principles of Lean:
- Define value from the standpoint of the customer
- Identify value and remove waste
- Replace waste with value
- Continuously improve
OUR WORK
We have helped optimise businesses across many sectors and in many countries.
