NEW PRODUCT DEVELOPMENT IN AN ENTREPRENEURIAL COMPANY
by Rajeshwari Krishnamoorthy
Abstract: Entrepreneurial orientation is positively related to new product development(NPD). Through indepth case studies of two entrepreneurial companies in the consumer packaged goods sector, this study arrives at a set of findings regarding new product development. These include aspects of new product process, role market research in NPD,consumer insighting and evaluation of NPD. The findings can be used for future theory building in the area of new product development.
Keywords: New product development in Entrepreneurial company; New product development in Consumer packaged goods; Case research in new product development,NPD.
A VSM and VSA Methodology for Performance Assessment of Complex Product Manufacturing Processes: An Industrial Case Study
by R.M. Chandima Ratnayake, Dorota Stadnicka
Abstract: Value stream mapping (VSM) aids in visualizing an entire manufacturing system (MS) including potential entities such as: flows, processing times (PT), and lead time (LT). Although the visualization of the value stream aids performance assessment (PA) of the different sub-processes in an overall manufacturing process (MP), when it comes to a complex product (CP), the value stream map (VS-Map) and value stream analysis (VSA) become significantly complex in the PA of an overall MS. Also, the application potential of VSM capabilities has not been significantly exploited for VSA, PA and waste reduction (WR) in complex products manufacturing processes (CPMPs). This manuscript illustrates a VSM based generic methodology that enables the visualization, PA and WR in a CPMP. The VSM, along with Kanban, enables modeling and implementing an order-driven or pull MP together with just-in-time material (or semi-finished items) arrivals. The work-in-process inventories are constrained by Kanban cards together with supermarket systems. The manuscript also proposes a number arrays-based approach that enables a comprehensive VSA when the VS-Map becomes significantly large and complex. A case study has been performed in collaboration with a saw-blade sharpening machines manufacturing firm to illustrate the use of the suggested VSM based generic methodology and number arrays in VSA for PA of CPMPs. The calculated lead time of the case study CP is almost 323 days. All cycle times are smaller than takt time (TT) (i.e. 600 min). Changeovers (COs) are not a challenge because they are not on the critical path.

An Integrated Fuzzy MCDM approach for Risk Evaluation of New Product in a Pipe Industry
by Ehsan Pourjavad, Wei Peng
Abstract: One of the most important processes that keep a company competitive is New Product Development (NPD) which includes high risk and uncertainty. Hence, most companies try to find a good method for identifying, managing and reducing the risks of this process. For this reason, this study aims at accelerating new product introduction and improving the quality of decision-making in NPD process under risks and uncertain conditions. This paper suggests an integrated framework based on the Fuzzy Analytic Hierarchy Process (AHP) and the Fuzzy Technique for Order Performance by Similarity to Ideal Solution (TOPSIS), to help managers evaluate new products in a fuzzy environment where the vagueness and subjectivity are handled with linguistic values parameterized by triangular fuzzy numbers. The Fuzzy AHP is implemented to analyze the structure of the new product selection problem and to calculate weights of the risk criteria, and the Fuzzy TOPSIS method is applied to obtain a final ranking. Finally, an application of the suggested model is applied to the pipe and fitting industry to demonstrate the feasibility and potential of the methodology. The results reveal the supply risks have the highest effect on risk evaluation of new products. The findings also indicate 900 Elbow has the lowest risk among products in this company.

Design for Product-Service Systems: a procedure to enhance functional integration of product-service offerings
by Nicolas Haber, Mario Fargnoli
Abstract: Design and development of an integrated Product-Service System (PSS) aims at replacing stand-alone products or services with a functional offering. However, issues regarding this transition are dissimilar and differentiated. This study discusses the importance of PSSs analysing the theoretical studies accomplished in the extent of their design and development processes. Based on this, a novel procedure, built on the Design Science approach, is proposed, where the distinct models from the literature are merged towards a unified structure serving as a robust and generic methodology for designing PSSs. Each stage of this process is then developed to present a comprehensive design procedure, called the Functional Engineered Product-Service System (FEPSS), which is based on morphological thinking to conceptualize PSS offerings. A case study illustrates the use of the proposed framework underlining its effectiveness in merging stakeholders needs, development activities, as well as products and services elements enclosed in the solution.
