Takt time is an important lean manufacturing concept that was developed by Toyota to help balance production lines and optimize process flow. To define the term more specifically takt time is expressed in seconds and is used to determine the “rate of customer demand by dividing daily demand in units into the time available for production” (Mann, 2010, p. 270). It important to note that takt time is performed for individual processes so that each step in manufacturing is balanced to takt time, or as equal in length of time as possible. Takt time is therefore much different from cycle time which is overall process time (Huang, Li, Yuan, Gao & Rao, 2012).
Takt time is used to balance production times by assigning tasks by the longest takt time so that each workstation has a similar amount of work (Meredith & Shafer, 2016). This focus on time prevents bottlenecks for some activities and idle or non-productive times for other activities. The goal is to balance the work flow for the most efficient throughput and work in process (WIP) from a value stream perspective.
Why Takt Time Was Selected For Study
The selection of the topic is to help me better understand the utilization and application of the takt times to balance production in an automotive manufacturing environment in Juarez, Mexico. Currently, in the company I work the other functions inside the work cell simply operate with considerable idle time according to the one major bottleneck or time constraint.
One of my goals is to streamline the cellular process by work redistribution and perhaps reduce the overall number workers due to a lack of readily available workforce and turnover. Turnover is a relatively new phenomenon in Juarez and since training times in c...

... Edition). This quote is particularly relevant as takt time is a critical metric used to balance manage time in manufacturing and service applications and can be applied to many aspects of our lives. We learn to use time wisely.
Application of Takt Time
In summary, takt time methods are truly a foundational tool used to balance production line flow. Through careful evaluation of the process or even product with the longest takt time; a manager can better visualize and control the entire value stream. Reduction of waste, or in this case idle time and operating efficiently in all processes outside the bottleneck is one of the critical applications of takt time analyses. Through the use of takt time, various scenarios and work group variables can be trialed, until the optimal solution is determined. The optimal solution matches the tact time to the overall cycle time.

- The Toyota production system has not only been a major influencer in the Automobile industry but the socio-technical system has also impacted other industries. Taichi Ohno the father of Toyota production system started with the following goals his mind .he wanted to eliminate waste ,inconsistency and overburden. The basic objective was to design for smooth flow of process which would occur by eliminating inconsistency(mura),making it flexible by nullifying stress(muri) as this causes waste(muda).Succintly,they wanted to remove everything that does not add value to a process making it function effortlessly....

- Safety and the Concept Car An area of significant importance in the world of concept design, is the improvement and understanding of how vehicles can be made safe and harmless to the environment we live in. In recent years the worlds population has become aware of the devastating effects our lifestyles are having on our planets resources, and naturally our transportation has been held responsible for some of these problems. This topic has therefore become one of great interest to the creators of new concept cars, giving designers the opportunity to materialise ideas which really could change the world....

- Karl Marx, Immanuel Kant and Aristotle have all had philosophical notations on the importance of meaningful relationships. In the late 19th century production and commodity obsession began to grow wildly and it heavily exists today particularly in North America. I’m going to show how we ought to govern our relationships according to Marx, Kant and Aristotle and that our contemporary view of production is faulty in that it is exploitation of human relationships. First, I’m going to show this through the early writings of Marx in the ‘Estrangement of Labor’ where he explains how working class people are alienated in several ways by the capitalist economics....

- The Concept of Identity To answer this question, it is important to first understand what is meant by identity. Identity concerns both self-identity and social identity. It is best understood not as an entity but as an emotionally charged description of ourselves. It is about the personal and the social as well as about us and the relations of others. It has been argued that identity is wholly cultural in character and does not exist outside of its representation in cultural discourse. Identity is ultimately not a fixed ‘thing’ but a becoming....

- The concept of the microbial loop first began in 1926 by Vernadskii, who studied heterotrophic and phototrophic microbial metabolism; and understood that these systems represented a major part of total metabolism in the oceans (Pomeroy, 1988). Older techniques that scientists used for enumerating marine bacteria were by plate counts, serial dilutions and phase-contrast microscopy. These numbers represented about 10% of actual numbers and are no longer used (Azam et al, 1983). Scientists were unable to completely understand the microbial loop until recently when ultrafiltration techniques, applied electronic microscope techniques; and genomic techniques were developed to quantify biomass in...

- Background of the study- Lean thinking concept was earlier recognized in the 1980s when the American car manufacturing industries realized that Japanese industries have been producing cars at a much cheaper cost with better quality. This realization was a result of Kiichiro Toyoda, Taiichi Ohno, and others revisiting the production system of Ford and thus inventing Toyota Production System. Lean manufacturing concept was presented by (Womack, Jones, and Roos 1992) Womack et al. in 1992. This Lean concept mainly aimed at reducing wastes of all forms recognized namely defects, waiting, over-production, rework, motion, processing, inventory and transport....

- LEAN PRODUCTION – THE TOYOTA WAY Lean production is an approach to production developed in Japan. Toyota, the Japanese car manufacturer was the company that invented lean production. The whole aim of lean production is to reduce the quantity of resources used up in production. By doing this, lean production uses less of - factory space, materials, stocks, suppliers, labour, capital and time. Lean production reduces costs, increases efficiency and output and improves motivation. Lean production involves using a range of practices designed to reduce waste and improve productivity and quality.... [tags: Business Manufacturing]
