David Scott

David Scott - Lean Sigma Institute

Member of the Lean Sigma Institute Advisory Board.

David has over 20 years experience in organisational development and business improvement, half of that in Sweden before moving to Australia.  He sees the customer interface as a critical starting point for improvement, but that only by considering the needs of all stakeholders, including suppliers, owners and employees as well as customers, can an organisation achieve its true potential. 

David has a passion for improvement that focuses the organisation on the need to develop customer oriented processes, systems and culture.  Obstacles to this, in the organisational culture, its structure, systems and capabilities need to be identified, managed, minimised and, where possible, removed.  

From the beginning of his career, David has been involved in education and training with a strong belief in its power to change individuals and organisations when structured, focused and supported in appropriate ways. 

He is the co-author of two books on improvement technologies and management systems - The QS-9000 Continuous Improvement Handbook and QS-9000 A Practical Self-Help Guide: Experiences of Australian Companies, and lectures at post-graduate university level at RMIT, in Organisational Change and Organisational Interfaces.
