Our paper analyzes close collaboration between a manufacturer of domestic appliances and consumer electronics and its customers. It reflects on the inclusion of open innovation by users that is presented in the paper on the case of the development of the refrigerator door handle, with an emphasis on design and functionality. The main research question we wanted to answer was whether a buyer (customer/consumer) might actively participate in the process of a new product development. It was interesting to test it in a highly dynamic industry setup since white goods are becoming an integral part of consumers’ life style and not just a mere home appliances used for routine housekeeping tasks. Research sample includes 146 respondents. We applied the conjoint analysis and quality function deployment (QFD) in order to test and understand how customers perceive the different attributes of a new product development process.

This article provides guidelines for optimizing organizational management styles and achieving a balance between life and work. Contributing to sustainable human development will contribute to the psychology of sustainability and sustainable development. The main purpose of the paper is to determine the relations between the preferences of management styles, working styles and lifestyles, and exposure to stress in the managerial population in order to achieve harmonization. A correlation study was conducted on a sample of 618 subjects using the Blanchard test of situational leadership, the Four-Dimensional Symptom Questionnaire for determining the stress levels, the modified Allport–Vernon–Lindsay Scale of Values, and Julie Hay’s Working Styles Questionnaire. The paper provides insight into the contribution of management styles to the balance of private and professional areas of life, as well as to stress reduction in managers.

Maintenance Management. The textbook describes maintenance functions designed to determine performance and ensure the efficiency of the production process. To understand production efficiency, the concepts of efficiency, reliability and maintenance of production equipment and their impact on maintenance costs are first explained. Integrated productive maintenance is a concept that has succeeded in bringing together all the good practices that have evolved through the development of preventive maintenance, reliability based maintenance, integrated quality management (TQM) and the so-called lean manufacturing principles. Aspects of introducing integrated productive maintenance are presented, with an emphasis on methods that have proven successful in the Western world. The most important of these is the measurement of total efficiency, which shows the magnitude of production losses. The 5S, SMED, and 20 key methods described below serve to eliminate basic company losses and thereby increase the factor of total equipment efficiency. Učbenik opisuje funkcije vzdrževanja, namenjene ugotavljanju storilnosti in zagotavljanju učinkovitosti proizvodnega procesa. Za razumevanje proizvodne učinkovitosti so najprej pojasnjeni pojmi učinkovitosti, zanesljivosti in vzdrževalnosti proizvodne opreme in njihov vpliv na stroške vzdrževanja. V nadaljevanju sta podrobneje pojasnjeni metodi preventivnega in vzdrževanja na osnovi zanesljivosti. Celostno produktivno vzdrževanje je koncept, ki je uspel združiti vse dobre prakse, ki so se razvile skozi razvoj preventivnega vzdrževanja, vzdrževanja na osnovi zanesljivosti, celostnega upravljanja kakovosti (TQM) in tako imenovanih vitkih načel proizvodnje. Predstavljeni so vidiki uvajanja celostnega produktivnega vzdrževanja, s poudarkom na metodah, ki so se uspešno izkazale v zahodnem svetu. Med njimi je najpomembnejše merjenje skupne učinkovitosti, ki pokaže velikost proizvodnih izgub. Metode 5S, SMED in 20 ključev, opisane v nadaljevanju služijo odpravljanju osnovnih izgub v podjetju in s tem višanju faktorja skupne učinkovitosti opreme.
