Steigende Individualisierung und hohe Marktunsicherheiten zwingen Unternehmen dazu, ihre Kunden kontinuierlich in die Produktentwicklung einzubinden und Produktänderungen auch in späten Entwicklungsphasen zu berücksichtigen. Die hochiterative Entwicklung physischer Produkte bietet ein großes Potenzial, um diesen Herausforderungen zu begegnen, führt jedoch zu neuen Anforderungen an die parallel stattfindende Planung der Fertigungstechnologien. Die resultierenden Anforderungen an die Technologieplanung werden in diesem Fachbeitrag vorgestellt.   Increasing individualization and high market uncertainties force companies to continuously involve their customers into the product development and to cope with product changes, also in late stages of product development. The highly iterative development of physical products offers potential to face these challenges. However, it causes new requirements towards the planning of manufacturing technologies, which is carried out in parallel. The resulting requirements to technology planning are presented in this article.

Theory Of Evidence

Abstract Highly iterative product development is a promising approach, which enables a continuous inclusion of customers in the product development process. A stronger involvement of customers results in more frequent changes of the required product characteristics while the product is being developed. For the planning of manufacturing technologies, which takes place in parallel to product development, this means that very uncertain product and technology information have to be processed. In order to consider these uncertainties when designing technology chains, technology planners have to be able to model and quantify them. Moreover, due to the frequent product changes during the highly iterative development process, an evaluation of how capable manufacturing technologies are for handling future changes of product characteristics is essential for technology planners. This paper presents a new methodology, which enables the evaluation of manufacturing technologies regarding their capability to react to future product changes within the development process. Firstly, a new method based on fuzzy sets and the Dempster-Shafer theory of evidence is presented. It allows an aggregation of uncertain product and technology information from different sources. Afterwards, the influences of manufacturing technologies within a technology chain on the product characteristics are modeled considering the different uncertainties. Finally, a new method to evaluate the capability of manufacturing technologies to cope with future product changes is introduced. This allows technology planners to predict the capability of manufacturing technologies to manufacture the future, fully developed product and hence to identify alternatives to reduce the information uncertainties, for example by executing prototype experiments.

Development Methods

Agile, and iterative, development methods for new product development are gaining in popularity under product engineers; where it initially was just applied for software development, now larger adoption takes place for product development in general. The design rules of agile development are somewhat conflicting with the guidelines of Axiomatic Design. In this paper, it is investigated why this is the case, what can be done about it, and how can the strengths of agile development be combined with Axiomatic Design to optimise methods for product design. It is shown that the methods are indeed advising on different and conflicting strategies, however, by attenuating the agile design rules in the early stage of design, and doing the same for AD in the later stage of design, best of both worlds can be combined.

Analyse Case

The reverse innovation concept has gained traction in the practitioner and academic domains since it alters the traditional view of innovations flowing from developed countries to emerging markets. Reverse innovations depart from the assumption that product development appeals to value offers with reduced performance and radically lower price points for consumers in emerging markets. Existing literature on reverse innovations has been limited to analyse case studies and anecdotic evidence but a systematic framework is needed to innovate in systematic ways. Drawing from the technology planning and forecasting, this paper proposes that technology roadmaps are suitable tools to analyse how a reverse innovation designed initially in an emerging market encroaches developed countries. At the firm level, roadmaps integrate technology planning, product development, and market aspects. Hence, they become suitable tools to design and commercialize products and services based on the reverse innovation paradigm.

The Impact

Injection moulding is a major used technology in mass production of high-quality plastic and composite parts. Once the initial costs have been paid the price per produced part is extremely low and part is then created up to million times. On the other hand, the product development process is time-consuming and costly due to preparation time. Therefore, the efficiency and similarity to real production are essential. Injection moulding into polymer injection mould cavity inserts appears to be an appropriate step in the product development process in particular concerning quickly developing additive manufacturing technologies. Though polymers are thermal insulators, therefore, cooling time is longer compared to injection into fully metal moulds. The impact of different cooling conditions is a change in the crystallization of injected material causing different mechanical properties of products. Removable injection mould cavity inserts were made from PET (Polyethylene terephthalate), PEEK (Polyether ether ketone), PSU (Polysulfone) and PTFE (Polytetrafluoroethylene). The main goal was to compare crystallization and thermo‑mechanical properties of injected PP (Polypropylen) parts into polymer cavity inserts to those injected into a steel mould.

PurposeThis study attempts to create new insights into innovation management through the integration of innovation management processes and sustainable, iterative circles. Through the exploration of the use of sustainable, iterative circles in a manufacturing environment, this paper explores their role in facilitating customer-focused innovation practices. Other supporting antecedences for innovative behavior are reviewed, and their combined effect upon delivering cost-effective product developments are assessed.Design/methodology/approachData were collected through semi-structured interviews in manufacturing organizations from the automotive industry. Interviews were conducted with senior functional managers to interpret the application of sustainable, iterative development circles. Analysis of the data was undertaken via thematic analysis based upon pertinent and emergent themes.FindingsSustainable, iterative development circles overcame the inherent path-dependency of traditional linear development approaches, whereas, traditional approaches structure the involvement of key business functions, iterative circles facilitate more flexible approaches to product development that more closely met the requirements of the customer, especially when those requirements are in a state of flux.Practical implicationsThis iterative, customer-centric approach to product development reflects the increasingly dynamic market environments in which manufacturing organizations operate. Using this approach helps to focus the organization’s attention upon customer requirements rather than the challenges of adhering to the rigid dogma of a chosen development methodology.Originality/valueThis study proposes a new approach toward the development of innovations in manufacturing organizations utilizing the sustainable, iterative circles, and therefore, contrasts with the traditional, linear development methodologies that are usually employed.
