Certainly, value creation is not always translated into achievable profit. Profit depends mainly on market conditions and the ability of an enterprise to differentiate itself from competitors who seek to profit from loss of market share of other entities. This is an area that goes above and beyond lean, but once open lean prepares the company for flexibility, agility and openness, marketing strategies can greatly profit. The use of the word displacement and not transformation of a company has been preferred to state that, in reality, there is not a real change of a company into something else, but a displacement of standpoint and mindsets in the way of organizing and operating this entity.

The theory of topos has been founded for the development of relations which in the case of an enterprise define activities. These activities focus on flows of work, materials, information and cash in the factory. The CBVE concept promotes the reviewed perception of value and sets the consumer up as an active co-creator of new and differentiated value. It is well known that production contributes to the GDP Gross Domestic Product of a country and is therefore a key contributor to the development and growth of macro-economies.

Today, the majority of enterprises in many industrial and com- mercial sectors are organized, managed and measured based on the principles and rules of mass production. However, value creation is slowed down by the many types of waste inherent in the way organizations operate and account for perfor- mance.

Production has a long history, passing through two industrial revolutions. Scientific Management and production as a science were contemporary with those of great revolutions and scientific changes at the beginning of the twentieth century and the wish of society at that time for change. Advances in mathematics and physics have brought everything they could under their umbrella.

The development of operations research created hopes to enterprises which looked at advanced mathematics to solve the problems and challenges in managing production. How- ever, the gradual distancing of researchers from the reality of every day practice and value creation, led operations research, in our opinion, to a highly theoretical level of research for the sake of research.

At the same time, production management was deprived of practical use and support from operations research. The complete separation of the theoretical base from the practice of creating value did not help neither operations research nor businesses. Nowadays, where concepts of production and value are reviewed, where the economy is increasingly individualized, the role of mathematics is not as exclu- sive as it was at the beginning of the twentieth century.

In those days, most of the important algorithms and formulas were developed, laying the foundations for the development of businesses organisation. At the beginning of the 50s, classical inventory theory played a central role in production control, in times when whatever could be produced from a factory always had a customer waiting to buy it. In such practically unlimited markets, availability of inventory was an advantage and therefore the sole target of companies was the minimization of production costs through higher output in building and maintaining inventories.

Investing, in the best case scenario in a slow moving inventory, essential resources from working capital necessary for operations sustainability are deducted. While market conditions have changed and sellers markets everything production can produce is sold have moved to buyers markets only what can be sold is produced , enterprises loyal to the methods of managing production for maximizing inventory observed that their needs for working capital increased compared to the past.

The way they chose to follow for acquiring working capital was to approach the banks, instead of looking for opportunities to eliminate the cause of the increased needs in capital. The cause was obvious and the solution even more obvious. Production must produce what will be sold according to demand and not according to forecast. Working capital was released mainly through the drastic reduction in finished goods inventories. Nowadays, there is widespread belief among many organizations that working capital comes only through loans.

This belief is also carefully sustained by the banking system, the role of which should have changed to prepare itself for the new era. Lean production helps organizations to gain back their capital buried into finished goods and work-in-process inventories. Lean enterprises can achieve through zero working capital their gradual independence from the banking system.

This event continues to be confirmed in numerous implementations of lean practices throughout the world. Lean enterprise is a worldwide reality today, especially in the Western world, on both sides of the Atlantic. In Europe, lean thinking and practice has enjoyed immense recognition and it has become the means of survival for companies of any size in many countries nowadays, while for others it is becoming the vehicle for sustainability in value creation.

The results achieved and delivered are undoubtedly remarkable. It is, however, important for companies that engage themselves on this journey to prove to themselves that they can achieve results as well. Above and beyond the use of tools and methods for redesigning production lines and supply chains, a great deal of lean implementation is effected through changing ways of thinking, operating, measuring and accounting for performance.

This applies to all stakeholders inside and outside the company; owners, management, employees, workers, suppliers and even customers. Lean is the business model for lean markets characterized by reduced consumption and therefore reduced energy requirements. This is a different growth model than simply a capitalist model based on lean thinking. In this book the following value chain activities are addressed: production operations and internal logistics, procurement and relations to suppliers, demand and supply based planning and the important issue of cost accounting and value creation in a lean environment.

I had the great fortune and honour to work as a trainer and director of technology in his company in many countries in Europe and also in the USA. Colleagues from that time based their professional future partly on this method Hobbs This method they called Lean Production as opposed to Mass Production.

From the system of production management at Toyota known as Toyota Production System, a set of tools was created so that this new concept could be implemented in the USA, from where TPS found its way to Europe Ohno Today it is a choice that has been implemented with recognized success in many industrial and non-industrial sectors.

Although the Japanese never used the term lean production, many tools from their system began to be used in implementations in the West. Many kept the same name as in the language of origin. Terms such as Kanban, Kaizen, 5S, Visual Manage- ment, Gemba, are some of the most known tools used in implementations of lean production.

Furthermore, new tools were developed, for example VSM Value Stream Mapping which helped to improve the way of implementing lean practices. In the meantime, lean production became a subject of study and research at many Universities both in the USA and Europe and there are already an increasing number of scientific and non-scientific publications on the issue. Scientists researching the production sector have started developing complex mathematical approaches for modelling activities that should really be left lean and simple.

The term lean production has survived all other potential alternative terms such as Demand Flow Technology or Flow Manufacturing while other terms such as agile or flexible manufacturing were incorporated into the term lean production, and are widely known today. Studying the literature and various implementations of lean production based on the principles that Womack and his colleagues have developed in the Lean Enter- prise Institute, the use of any implementation methodology is not obvious.

It seems as if the way of implementing lean depends on the choices and the experience of the consultants who undertake to carry out the project. The method of lean flow presented in this treatise incorporates VSM in the method of Constanza in order to cover the complete supply chain.

Furthermore, the method has been successfully implemented in office environments as well as in health care organizations such as hospitals, medical centres and pharmacies. Recently, lean thinking entered the sector of electricity production and distribution, replacing the current paradigm of mass production, which we believe will lead to a truly liberalized electricity supply and not as it is propagated by the European Union, which is the replacement of state monopolies with private monopolies Tsigkas The essential contribution of Constanza was to adapt the production manage- ment methods he learned in Japan to fit Western industrial culture.

He developed a method which is generally valid for almost all production types; it can be individuated for each particular implementation and is totally customer-centric.
