Total Productive Maintenance (TPM) is the Japanese approach to maximise the effectiveness of the facilities that are used within businesses. In general, TPM aims at getting the most efficient use of equipment and establishes a total PM system including maintenance prevention, preventive maintenance, and improvement-related maintenance for the company.
Total Quality Management (TQM) is a way of thinking and working, that is concerned with meeting the needs and expectations of customers. It attempts to move the focus of quality away from being a purely operational activity into a major
concern for the whole organisation. TQM is a philosophy of organisation-wide commitment to continuous improvement, with the focus on team-work, increasing customer satisfaction, and lowering costs. This concept of TQM is very similar to the workings of TPM - in that customer satisfaction is the ultimate aim.
TQM is ultimately an umbrella term that covers every quality and productivity initative that you make in the organisation.
