Japanese engineer who developed the Quality Loss Function and a set of techniques of Design of Experiments. After a long teaching career in Japan, he successfully applied his methods at Ford in the 1980s.
Late former Vice-President of Toyota Motor, who is credited for the development and implementation of the Toyota Production System.
It is said that Taiichi Ohno had the idea of developing a production system synchronised with final demand when, visiting a supermarket in the US, he observed how the products were quickly replaced in the shelves after having been bought.
German word referring to the musical tempo given to an orchestra by the maestro. In Lean Production it means the demand cycle time. It is obtained by dividing the net available production time by the customer demand, in the same period of time. The cycle time of each process should be in accordance with takt so that production precisely matches demand.
In 1965, in Japan, Toyota created Target Costing (Genka Kikaku).
It is a methodology to design and produce a product or service within a predefined cost budget, and to ensure the desired profit margin in order to match the sales price defined by the market.
Target Costing is ruled by the following principles:
• The cost is guided by the price
• Customer focus
• Project focus
• Company engagement as a whole
• Oriented to the live cycle cost
• Supply chain engagement
Tataki-dai comes up in Lean as an approach to improvement where just the main topics of an idea are presented to a group of people, before coming up with the final proposal. This way, the discussion is open to incorporate contributions from other people, increasing the probability of implementation, since acceptance is better when people are consulted. Besides that, a more solid proposition is built, since many more possible difficulties are foreseen than if this process was individual.

The automotive manufacturer that continues to be the reference in productivity and quality. Toyota is a single case in the automotive industry for always having positive results. It just has surpassed GM as the largest world manufacturer. Toyota Production System was developed at Toyota

TPM - Total Productive Maintenance
Much more than a maintenance methodology, it is a management system aiming at optimizing Operational Efficiency throughout the equipment’s full life cycle. It promotes the identification and elimination of all effectiveness losses. Productive maintenance was born at Denso, an automotive component manufacturer belonging to Toyota. It actively involves operators and other production staff, not just maintenance personnel. TPM is structured in 8 pillars, including:
• Prevention of equipment losses
• Autonomous maintenance
• Planned maintenance
• Quality improvement
• Planning of new equipment
TPM is a registered trademark of Japan Institute of Plant Maintenance.
TQM – Total Quality Management
Management Strategy focused on improving quality in all processes of the organization, including suppliers and customers. It was developed by W. Edwards Deming and Joseph M. Juran in postwar Japan and utilizes various improvement tools such as PDCA, the 7 Quality Tools and Kaizen. It later evolved into what is now known as 6Sigma.
TWI – Training Within Industry
Skills development methodology based on five training pillars: working methods, work instructions, labor relations, problem solving, and safety.
TWI was developed and widely applied in the United States in the period between 1940 and 1950 with the aim of increasing the production of the military industry. During this time aproximately 1.6 million people were trained
