The chapter will describe the studies which the book project has finallyfeatured and how the analysis and thesis forming part of the book havebeen arranged. The chapter will describe and show how the thoroughstudy of the subject –High Speed Product Development Processes andModels Based on Networks (NB HS PD)– together with the explo-rative analysis of the product development system of generic industrialcase businesses including related models and processes have come up.The aim was to describe and analyse the current context in 2000–2003 ofnetwork based high speed product development and make an identificationand introduction of the NB HS PD problem –what is the problem?,anidentification and introduction ofwhy NB HS PD is a problem?Theaim was further to describewhen NB HS PD is a problemand givean introduction to the theoretical model apparatus for high speed productdevelopment processes and models, Further the chapter gives an intro-duction towhen NB HS PD models and processes can be used?withpreference.The chapter gives an introduction to how the theoretical frameworkoutlined above was subsequently empirically tested in case Businesses, focusgroups and survey with an explorative focus. The chapter introduce shortly theempirical part and study of Danish and foreign international case businesseswhich had established network based product development processes andmodels and which employ and try to employ HS PD based on networks.This chapter explains how the study contributed towards an explanation toprocesses and models for product development carried out at high speed anddeeply rooted in networks.On the basis of the above the chapter finally will describe how the finalpart of the book is concluded. In the first decade of the 21st century product development in networks waspredicted to be of ever-increasing importance to businesses of all sizes becauseof changes in markets, in technology, in networks, and in the competencesof Businesses (Nonaka & Takeuchi, 1995) (Sanchez,1996) (Coldmann&Price, 1998) (Child and Faulkner, 1998). The growth in new products’ shareof businesses’total turnover and earnings were increasing at an unprecedentedspeed.The entrepreneurial innovations and technological improvements hadresulted in the increasingly fast development of new goods and services.Businesses and industries in different countries became more and more linkedand interdependent in networks with respect to materials, business operationsand particularly product development to match the wants and needs of theglobal market environment to high speed product development.Businesses were therefore encountering increasingly dynamic marketfragmentation, shrinking time in market, increasing product variety, demandsof production to customer specifications, reduced product lifetimes, andglobalisation of production. In the years up to the 2000–2003, manyindustrial businesses had seen the necessity of applying network basedhigh speed product development in order to compete on the globalmarket.
