Situational Management Support Systems

Digital natives increasingly populate organizations?? management. These new-generation managers more naturally accept management support systems (MSS), but also have higher expectations about how they should accommodate their individual user preferences. As a result, managers question MSS that have been developed without configuration mechanisms to accommodate their working style, relevant MSS use cases, and different MSS access modes. The objective of this article is to reveal managers?? different MSS use situations and propose levers for tailoring (conceptual) MSS design to them. Use situations generalize classes of similar user-group preferences. We first apply findings from a literature review to cluster managers?? user-group preferences into 36 MSS use situations. Second, we propose that the selection of end-user devices can serve as a main lever for MSS configuration. Third, we complete the configuration with a MSS user-interface design. Finally, we demonstrate utility of our configuration model by presenting and evaluating a prototype.     

Proze?orientiertes produktionscontrolling

Proze?orientiertes Controlling erlaubt eine umfassende, differenzierte und zielgerichtete Steuerung des Produktionsprozesses. Besondere Bedeutung kommen dabei der Beachtung der Controllingkriterien vor einer Entscheidung sowie dem Forward-Controlling zu. Abh?ngig vom Produktionstyp ist das Controllinginstrumentarium unterschiedlich zu gestalten. W?hrend für die Einzelfertigung Kostenkriterien im Vordergrund stehen, stellen für die Serien-/Proze?fertigung Ressourcen, Termine und die internen und externen Qualit?tsfaktoren die wesentlichen Controllingkriterien dar.     

Energy use and fruits and vegetables

The consumer has many options to save energy through small dietary changes. With no change in the variety of fruits and vegetables eaten, the consumer can save considerable amounts of energy by bringing them to the table without use of a home freezer, frequent long distance shopping trips and oven cooking. Other conservation measures include buying in large containers, eating uncooked food, using fresh produce rather than canned or frozen, except in the case of frozen juice concentrates, and having a home fruit and vegetable garden.
