"These methods work! Our years with Bill and Johan have helped us to apply the approached outlined in this very practical book. They have given us efficiencies at a level consistently higher than expected. They have changed the culture of the organisation in a significant way - we now consider 'Mining Gold' an every-day operation."

Quality and Projects Co-ordinator, VicRoads:

"You don't have to dig far to discover that this book is full of practical tips and advice, and by using these we have made a significant impact on our business. The 'Mission Impossible' case study is a real learning in itself and complements the theory very well."

"Bill Jarrard worked with us for several years introducing the concept of Total Quality Management and helping us implement it in a very effective and practical manner. This was one of the secrets of success. Now the secret is out! Bill and Johan have written a wonderful and practical guidebook to help others mine their improvement opportunities."

Deputy President, Quality Society of Australasia:

"At last! A book which not only provides a coherent management theory of Continuous Improvement, but also takes my hand and guides me through the journey. I wish I had this book ten years ago! Jo and Bill have a wealth of experience in this area. 'Hidden Gold' is a gem!"
