MatThink describes expanded input-process-output thinking strategies for using materials efficiently and effectively. Variables such as composition, shape, size, and finish that define the quality of the results are addressed. Variables affecting the quality of the results are also described. This book focuses on asking the right questions and thinking strategies to improve performance (employee, job, and business performance). The power of asking questions is that questions can apply to many different tasks and work environments. The types of question don't change but the answers may vary depending on the circumstances. The thinking strategies are applied to refining, manufacturing, modifying, and applying materials. Issues affecting the packaging, storing, and transporting of materials are also described. A Job Aid lists the thinking questions you can use to optimize material recovery and use. Learning activities help you apply the strategies to your work and home environment.
