Taiichi Ohno is a quality pioneer credited with the development of the Toyota production system and further converting the concepts into an integrated framework. The concept of the TPS helped Toyota to grow in leaps and bounds and stay ahead of its competitors even during the oil crisis of the 1970s (Ohno, 1988). Ohno enhanced the idea after visiting the ford factories in the USA to gain a better understanding of Ford's assembly line that followed the concept of a supermarket demand and supply chain. The supermarket idea follows the self-service model such that when the shop owners wanted to replenish their stock, they will order supplies just in time and reduce the inventory costs. The TPS concept was adopted by most industries to enable them reduce wastages increase efficiencies and optimize the cost of production ( Monden, 2011) .
Ohno’s TPS concept focused on reducing wastage and adding value to the organization. He identified seven areas where wastage is experienced or developed and which will be addressed by allocating the necessary resources to improve value. The seven wastes include:
Delegate your assignment to our experts and they will do the rest.
Overproduction: the products are more than what is needed or earlier than when it is needed.
Defects: caused by incorrect information, reworking, and scrapping
Waiting: time wasted before the next process begins
Inventories: too much information on materials and products that are not being processed.
Transportations: unnecessary movement move products, information, and materials
Motion: movement of people
Extra processing: additional procedures that do not add value to the products ( Shah & Ward, 2003) .
The common wastage step that has applied in my life and at home is the overproduction. For instance, it is costly to buy numerous varieties of foodstuffs that one will not finish or does not need at the moment. Instead, one can save the money or buy quality meal, but they will finish without wasting.
Henry Ford developed a production model that was meant to develop his company by controlling the resources of production, empowering the laborer and matching the supply with the demand levels. Taiichi Ohno expanded Ford's theory in both idea and execution when he introduced the Toyota Processing system that concentrated on reducing wastage on all aspects of management of production and consumption. Most organizations and industries in the current management world apply Taiichi's modified concept known as the lean management model ( Monden, 2011) .
