Good businesses know that they want to be should form the basis for their business of the future. fi rst to market with these solutions.

The early engagement of customers is whole workforce is engaged in addressing the issues. an essential, but sometimes overlooked, step in this It starts with simple resource effi ciency: turning items process. A good business puts its scientists close to its off when not in use, conserving energy and heat, and customers and provides the resources and direction for reducing waste to landfi ll. Then it moves into designing the science. new products that perform just as well as (or indeed better When employees and customers are all engaged in than) the ones they replace, but need less resources to sustainability at work, a partnership between business produce: production effi ciency.
