    MAPPING RISKS ON VARIOUS PRODUCT DEVELOPMENT PROCESS TYPES

    The goal of this research is to enhance the understanding of various categories of risks in product development (PD) and to carry out a comparative study on how risks occur in different phases of PD processes. Based on an extensive literature overview and the analysis of several risk identification methods, a Risk Breakdown Structure was created for product development. Mapping of identified risks, as the main contribution of the presented research, provides information about the existence of certain risk categories and subcategories in different phases of the product development process. The obtained information facilitates more successful risk identification in PD. The mapping was created in order to enable a comparison between certain PD process types by using the criterion of suitability for managing and coping with specific risk categories. To validate the proposed mapping, a questionnaire was sent to R&D organisations

    Eco-Evaluation in Conceptual Design Phase – A Case Study

    The use of qualitative eco-evaluation methods for product concept eco-evaluation is explored in a case study where mechanical engineers performed an eco-evaluation of product concepts in a two-stage evaluation process. In the first stage of the case study, the evaluators were asked to evaluate the environmental friendliness of the product concepts and to rank the concepts accordingly. The obtained rankings were based upon subjective preferences of the evaluators and their subjective interpretation of the eco-value of the considered concepts. In the second stage of the case study, the evaluators eco-evaluated the same concepts, but this time they used ecodesign guidelines as eco-criteria. The evaluators have obtained different rankings of the concepts, so the results of the two sets of rankings are compared. Findings are analysed in the context of confounding variables of the case study design

    Purpose of this work was to show connections between vertical hydrogenerator design parameters. Authors made DSM (Design Structure Matrix), to show design parameters dependencies, first matrix size was reduced and it does not consist of all design parameters, it consists only of more relevant design parameters to be solvable. Final size of matrix is 221×221. Matrix shows that electrical generator in some ideal conditions could have almost straightforward path during design procedure. DSM matrix is still in process of verification. After finishing DSM of design parameters, authors made MDM (Multi Domain Matrix) which connects design parameters with mechanical calculations and generator main drawings. This matrix has the purpose to help managers, electrical design experts, other design experts and any others who should not need knowledge about generator design process to easily track changes between parameters and to see how change of some parameter affects drawings and calculations. At the end authors made VBA program which visually shows connections

    Procjena i odabir ideja u procesu inovacije proizvoda – rezultati empirijskog istraživanja

    The process of innovation takes significant resources, and therefore it is of great importance for companies to recognize the ideas with high innovation capacity as early as possible, and in a transparent manner, with the least necessary amount of expert knowledge. Current research indicates that companies often carry out the selection of ideas ad hoc or intuitively, and that only a small number of companies have defined the methods for ideas assessment and evaluation. In doing so, such problems as imprecise definition of the variables used in the evaluation process of the innovation capacities of ideas, undefined metrics and interaction variables will arise. In order to determine the practical points of view in this area, a study was conducted in the form of a survey on a representative sample of Croatian companies which have product innovation in their production program. The survey is aimed at determining what motivates companies to innovate, and the ways in which companies carry out the assessment and selection of ideas. Through a thorough study of the literature, a set of variables that are commonly used in the idea capacities assessment for product development have been defined, and the survey tried to establish the practical significance of individual variables for the participants of the process. This paper presents the results of the study.Validerad; 2016; Nivå 2; 2016-12-03 (kribac); Procjena i odabir ideja u procesu inovacije proizvoda - Rezultati empirijskog istraživanjaMINMED- Models and Methods of Innovation Management in Complex Engineering Systems Development (www.minmed.org
