Do we have a quaUty process for rapid product development and market penetration Do we have a stream of product improvements Are we develop-ing common platforms for families of products (37) Are we developing improved processes concurrently with our new products How do we maintain our manufacturing processes at world-class levels (Fig. 5) (38) ... 

Product development models are the driving force for delivering the product to market on time and at the right cost. In general, the models in the literature can be divided into just two types sequential and concurrent. Each has its own characteristics, but there are several requirements that a new product development model should fulfil (Sum, 1992) ...

The automotive sector s quality assurance standard QS 9000 (1998) suggests a concurrent high level model, as opposed to the sequential model from BS 7000 (1997). This is shown in Figure 5.7. The automotive industry in particular has embraced the use of concurrent engineering models for product development, and this is reflected in the standards which facilitate their quality assurance programmes. A concurrent industrial model from the automotive sector will be discussed later. 

The Toyota X300 fork lift truck project design cycle is concurrent in nature spanning all the major disciplines in the process with quality assurance reviews, stipulating the use of appropriate tools and techniques at certain points. The product development process produced by General Electric is called the Tollgate Process . Again, it is concurrent in nature and includes ten review points. 

When a single technique is employed only local life-cycle cost minimization is achieved. If the global life-cycle cost is to be minimized, a number of techniques have to be applied (Watson et al., 1996). In this case, tools and techniques shouldn t compete with each other, but be complementary in the product development process. The correct positioning of the various off-line tools and techniques in the product development process, therefore, becomes an important consideration in their effective usage. Patterns of application have been proposed by a number of workers over several years (Brown et al., 1989 Jakobsen, 1993 Norell, 1993) and the importance of concurrency has been highlighted as a critical factor in their use (Poolton and Barclay, 1996). 

A key success factor for reducing the costs and lead times for vehicle manufacturers, for example, is the degree of integration of the suppliers within the product development process. This is seen as a natural extension to concurrent engineering principles (Wyatt et al., 1998). For many years, in engineering companies, a substantial proportion of the finished product, typically two thirds, consists of components or subassemblies produced by suppliers (Noori and Radford, 1995).

In biomass transesterification it is necessary to develop (basic) catalysts with high conversion efficiency operating under heterogeneous conditions, which avoid the presence of catalyst residues in the final product and allow a cleaner product with concurrent savings of catalyst, as well as simpler separation of the reacted materials from the reactants, e.g., integration of catalysts and membrane in a new advanced reactor design. 

Analytical methods validation—As mentioned earlier, a good CVMP should allow the analytical method to develop concurrently with the product formulation, thus in the early stages of development, an analytical method may not be fully validated but may still be used for cleaning tests as the best available method. At the time of the PAI, however, and definitely by the time the formal cleaning validation occurs, a fully validated analytical method should be developed. This methods validation package should include all the standard parameters, with special attention to the sensitivity of the analytical method as expressed by the limit of detection (LOD) and... 

The production of botrytized wines is initially limited by the special conditions required for noble rot development. Noble rot develops concurrent with berry dehydration. In the process, compounds present in the overripe grapes and produced by B. drierea become extremely concentrated. The result is the generation of wines with very high sugar and extract contents, and exceptional aroma richness. 

Through concurrent engineering and other approaches, lean product development has achieved astonishing results, requiring only one half or less of the time and human resources traditionally needed to develop a new car. Accordingly, it has become a cornerstone of time-based competition. Further means for improvement lie in the fuU exploitation of information technologies. In particular. 

Through these innovative practices, Toyota s lean production system formed a complete supply chain from source to user. Its system integrated suppliers and distributors with manufacturing and involved them in product development. In so doing, the lean production model has provided a prototype of the business paradigms of concurrent engineering and supply chain management. For an examination of the implementation of lean production in North American companies, see Liker (1998) and Liker et al. (1999). 

Usually information about customer needs may be delivered by sales and marketing. Typically, they rely on analyses of customer feedback and predictions for the future. These remain important sources of information for new product development. From this kind of information, the company may redesign existing products or decide to develop a new one. The design effort has to take place concurrently, with many experts involved representing various areas of expertise and parties that collaborate through the system. The supply chain companies may also participate if necessary.

The library, containing standard elements, can be tailored to the user s requirements for production and form elements. This ensures consistency between product development and the ability to manufacture the product. Therefore, only standard elements that match those of available production capabilities are made available. Feature definition, in the sense of concurrent engineering, is an activity in which all aspects of product creation in design, production, and further product life phases are considered. 

Accelerating the product development process is achievable through the minimization of unnecessary data retrieval and editing. Efforts to parallel the features of concurrent engineering tasks require integrated systems of design and production planning.
