The knowledge base for product development 155 It is important to recognise the science and technology information tracks so that they can be tapped into as problems arise in product development Research in industry is focused primarily on advancing technology to fulfil changing consumers'needs, whereas in universities and in many research institutes it is focused primarily on advancing either science or generic technology(Betz, 1998). In the science track, the knowledge is published in peer-reviewed journals and is eventually summarised in textbooks and taught to students although with modern funding in universities a significant amount of the knowledge is not published but is transferred directly and exclusively to the sponsors of the research. From an understanding of the current state of scientific knowledge, researchers in engineering and technology advance the knowledge in their disciplines by research on the basics of the technologies. This basic technological knowledge is published and taught to the next generation of engineers and technologists, and transmitted to their counterparts in industry in conferences and journals. In the early years of a new technology, a company works mostly with knowledge discovered during the industrial development Gradually technological knowledge sources are built up and these can be used in later development projects. A combined knowledge of the food system, and in particular the company's segment of it, is built up over the years by the companys R&D and its experience in marketing, production, distribution and engineering. This is the basis for future product development The company also looks for knowledge from its competitors, by studying their actions and products in the marketplace and their production, raw materials and processing. Most industries work from a similar technological base; 80% of the knowledge is known by everyone, maybe even more. In product development it is the extra 10-20% knowledge that makes the competitive edge, but the company also needs to have the capability to use fully the basic knowledge The company is creating knowledge along the whole system from the initial R&d to the final outcomes of the product in the market(Quinn, 1992)as shown in Fig. 4.2.

Even at the final stages where the new development has become a commercial reality, there is still knowledge being created about the product, production and marketing. Although there is a clear movement of knowledge from one stage to the next. there also needs to be interconnecting communications of knowledge between all stages so that the new knowledge is shared and the total company knowledge grows. There is also a need to evaluate the use and creation of knowledge in product development usually the embodied knowledge, particularly the product and its success in the marketplace, is used as the indicator of the knowledge achieved in the project Companies have difficulty in relating the knowledge created by fundamental research to the company's final profit. But fundamental research can be evaluated on the new knowledge and understanding that is passed on to product development. Just ask the product developers what it would cost them in the long term if the fundamental or the strategic research disappeared; or if strategic research improved its performance what extra value would that give to development! In the food industry in the past 20 years, R&D has tended to be either dropped or reduced one wonders how the company valued this asset, and how much it cost them to buy in this knowledge in the following years, and how many opportunities were lost. It is important that each knowledge-creating area is evaluated regularly to find which area is performing in creating knowledge that leads successfully to the long-term goals Invention is difficult to place in the knowledge flow because it is based on observation of what is happening maybe in a technology or in the community, unlike science, which is trying to discover new knowledge. Invention is not necessarily limited by the extent of scientific knowledge, inventors rely on their accumulated practical knowledge and their own intuition( Cardwell 1994). Invention requires some conceptual or imaginative creativity. To make an imagined transformation physically real, it also has to have the necessary technology, knowledge and skills. So it is an idea that has come to its time the idea may have been imagined a long time before but cannot be made real unless the various factors are present in people s knowledge and skills litcham, 1994). The concept of invention is the opposite of the incremental change. As well as taking place in an individual's mind over a short period, it can develop in a group through time together, but not substantially through systematic design. It is intuitive or even accidental events that lead to invention. The food industry has in the last 60 years been looking for the magical invention of a major new method of food preservation, but it has not come. There have been many improvements in drying, freezing, chilling and heat sterilisation, but there has not been the invention of a completely new method. Atmospheric control has been the one new preservation method that has gradually grown as packaging technology and inert gas production have improved. Although scientists have been studying it for over 60 years, the scientific knowledge has grown very slowly, but it is now expanding in combination with chilling for long-term storage and transport of vegetables, fruit and meat. Other methods, such as irradiation and the use of gases such as

158 Food product development 4.2.1 Strategic directions for knowledge It is management's role to ensure that there are the technological knowledge and capabilities to fulfil the companys overall innovation strategy and to implement product development strategies for the company. It is important to understand where they have been, where they are at present and where they are going. In the 1990s, there was a spurning of historical knowledge, which ended many times in reinventing the wheel. Today, there is recognition that there is a need to store reasonable percentage of this knowledge in a codified form for the future, because of the much greater turnover of staff and the loss of tacit knowledge. Total quality management introduced much more recording of production and product quality information. Now improved information systems make it much easier to store and retrieve knowledge of formulations and processing differences. Product formula tion is an area where there have been attempts to develop recording systems which an be used in later product development. For example using case-based systems the records of previous formulations- both successful and unsuccessful as a knowledge source with the product properties and their specifications can be retrieved to find a possible formulation for a new product(Row Over the years, this becomes a valuable source of company explicit knowledge hich can lead also to fundamental knowledge in the specific area of the company This is taking the tacit knowledge learned by experience and building it into generally available explicit knowledge Management needs to ensure that there is the needed knowledge in the company for their product development plans to be carried out. But there is al ways the question of how much money should be spent on knowledge in the company both in people's minds and in recorded knowledge how much on people and how much on an information technology system? Then how should this be split between the different stages of the product development project? If one looks at the stages of the product development project and the expenditure of money and man-days Cooper and Kleinschmidt, 1988)in Fig. 4.3, then we could say that the knowledge created is related to the man-days expended in gaining it. Figure 4.3 shows how the expenditure increases as the project goes to commercialisation, but the proportion of man-days spent was greatest in the product design and testing stage. There is a large capital expenditure in the later stages of the PD Process at the latest stages, but it is interesting that in Cooper and Kleinschmidt's study there was not a related increase in knowledge as epitomised in the time spent by people in the project Management needs to study the pattern of knowledge creation by people in product development and decide if it is optimal Management has also to ensure there is sufficient communication in the company to make full use of the present knowledge in the There is always a need to identify the knowledge needed in the future, both short term and in the long term; there may be a need to create new knowledge in the present product development project. In the incremental innovation strategy, this is building a bank of knowledge for future projects. But when innovation is more discontinuous, maybe to a new product platform or a new processing technology, then there is need for a new knowledge base. This can be a difficult

Product formulation is an area where there have been attempts to develop recording systems which can be used in later product development. For example using case-based systems, the records of previous formulations – both successful and unsuccessful – are used as a knowledge source with the product properties and their specifications, which can be retrieved to find a possible formulation for a new product (Rowe, 2000). Over the years, this becomes a valuable source of company explicit knowledge, which can lead also to fundamental knowledge in the specific area of the company. This is taking the tacit knowledge learned by experience and building it into generally available explicit knowledge. Management needs to ensure that there is the needed knowledge in the company for their product development plans to be carried out. But there is always the question of how much money should be spent on knowledge in the company both in people’s minds and in recorded knowledge – how much on people and how much on an information technology system? Then how should this be split between the different stages of the product development project? If one looks at the stages of the product development project and the expenditure of money and man-days (Cooper and Kleinschmidt, 1988) in Fig. 4.3, then we could say that the knowledge created is related to the man-days expended in gaining it.

Management has also to ensure there is sufficient communication in the company to make full use of the present knowledge in the company. There is always a need to identify the knowledge needed in the future, both short term and in the long term; there may be a need to create new knowledge in the present product development project.
