Product development process models

Before setting about the task of developing such a model, the product development process requires definition along with an indication of its key stages, this is so the appropriate tools and techniques can be applied (Booker et al., 1997). In the approach presented here in Figure 5.11, the product development phases are activities generally defined in the automotive industry (Clark and Fujimoto, 1991). QFD Phase 1 is used to understand and quantify the importance of customer needs and requirements, and to support the definition of product and process requirements. The FMEA process is used to explore any potential failure modes, their likely Occurrence, Severity and Detectability. DFA/DFM techniques are used to minimize part count, facilitate ease of assembly and project component manufacturing and assembly costs, and are primarily aimed at cost reduction. 

With this variable load and the generally complex factors affecting the mercury cell the task of optimising chlorine production is not easy. In a situation such as this a mathematical model of the process can be extremely useful. As a result ICI has taken advantage of a wealth of operational and experimental data for mercury cells, as well as experience in developing process models, to produce a dynamic model of a mercury cell. 

Independent of VDT, Steidel [426] developed a further detailed actor-oriented simulation model for product development processes at Berlin University of Technology. This model also ignored the particularities of process engineering. Likewise, the participative creation of the simulation model or the optimization of workflow management were also not supported by the methodology. Additionally, bottlenecks caused by the insufficient availability of resources could not be represented. In chemical process design, such bottlenecks can be caused by the restricted capacities of laboratories, for example.

The process view model takes a major role in defining, establishing, analyzing, and extracting the business processes of a company. It fulfills the requirements of transforming the business process, the manufacturing process, and the product-development process into a process view model. The process model is the basis for business process simulation, optimization, and reengineering. 

The product development process consists of six stages initial stage, specification alignment stage, initial models stage, product released to initial manufacture stage, production ramp stage, and product... 

Many companies require not only a modeler for geometrical elements but also application modules to integrate into their product development process and for computer intemeil imaging of the processes. Calculation modules and simulation software belong in this category. Such application modules must integrate with the modeler to form a functional entity (Figure 25). 

Definition of the problem Identification of requirements Establishments of goals Generation of alternatives Determination of criteria Evaluation of alternatives against criteria Validation of solution The similarity with most models of the design process - that not explicitly have their focus on decision making - is evident (Finger and Dixon 1989 Tomiyama et al. 2009) and illustrates the correspondence between decision-making processes and the product development processes. 

Product pipeline, product funnel Visual models of the way new products are developed. The concept infers a repetitive pattern for producing products. Supply chain design should be a part of the product development process. 

In a typical new product development scenario, we self-evidently would not have the Inxury of actual sales data prior to launch. To complete the picture we used an Eskin-type trial and repeat volumetric model to predict sales volumes for the same 15 products, as would typically be done at the end of the new product development process. The sales volume predictions were then modelled against the corresponding values for our derived index of fit-to-brand. The exponential function shown in Fig. 5.14 fits very well. 

Eigner and Stelzer [1] define PLM solutions as the functional and administrative backbone of IT solutions which comprise a number of IT systems and tools for CAD, CAM, CAE, simulation and visualization and which were derived in the 90s as an extension to PDM . Furthermore, they claim that PLM must be seen as a part of IT strategy to support the complete product development process and demands an integrated product data model, and technological and organizational preconditions in the enterprise. 

The concept of integration enables the consolidation of processes, systems and data with the objective of the availability of highly cross-linked development data over the product development process (Fig. 19.14). This integration has to happen both on the organizational level (clear communication mles by the use of V model aligned processes) as well as on the technical level (consistent interfaces and data models). To achieve the integration potential on system level...
