CORE ISSUES IN STRATEGIC MANAGEMENT: A SURVEY ON THE EFFECTIVENESS AND THE FUTURE OF THE MOST IMPORTANT MANAGEMENT TOOLS
Summary
Summary
Considering the number of management concepts and methods that are created, published and promoted it seems possible to create breakthrough initiatives every day. Unfortunately some of them are ephemeral fads with little effect on business success. Based on a survey of 114 German, Swiss and Austrian consultants this article tries to help managers to determine which concepts will be of significant importance in the coming years. The authors argue that shareholder value is out, strategic planning makes a comeback, downsizing, lean management und Total Quality Management were themes of the last century, knowledge management has to become more user-friendly to survive, and process management and Customer Relationship Management gain in importance.

VIRTUAL REALITY PLATFORM FOR DEVELOPMENT AND TRAINING ON FOUNDRY EQUIPMENT
Summary
Summary
VR models can be used to qualify and train operating personnel on the foundry equipment.
The foundry industry has great potential especially for developing well-directed employee training.
These training methods focus on creating virtual foundry machine models to test their construction, function and operation, as well as on their web-based use at distributed production sites.
A Virtual Reality platform for creating training scenarios developed at the Fraunhofer IFF is the base for further development of these training methods.
This technique was used in selected examples to illustrate the functioning of a typical foundry machine such as the crucible induction furnace and the cold box core shooting machine and to prepare it for virtual training.
Users can use the training scenario in an interactive 3-D model to obtain information on the functioning of the prototype foundry machines and to test their handling.By transferring important functions and editing the scenarios in a web-based format, the users can obtain access to training methods over the Internet, as required.

Use of simultaneous engineering in development of casting prototypes and samples
Summary
Regardless of the fact that cast irons are generally usable and from the point of cost structurally usable material the designers in varous branches make efforts to attain optimal shapes and strength properties of castings already in the phase of designing. Designers can nowadays reliably and quickly optimize the shape and thus the usability of a casting. 3D modelling and methods of finite elements enable reliable calculations and analyses of stress distributions, of wear and fatigue with simulation of real conditions. Improvement of the functional shape of a product and increase of the reliability in series production of single castings are enabled with analytical possibilities of the CAD/CAM technologies and the known software packages for casting and solidification processes, and they make it possible that foundry engineers already in the phase of simultaneous engineering actively cooperate in planning and designing a casting.
Two examples of the development and the optimization of a casting design that were achieved with simultaneous engineering will be presented in the paper. One of the projects deals with the development of a casting, the other one with an optimization. The first project is a case how the knowledge of engineers and process engineers can influence the development process of the engine bearer and how it is manifested in the final shape of the product. The second project presents the influence of foundry engineers and the importance of their knowledge in the optimization of the compressor block. All the activities related to the planning and designing a 3D model of the casting include partners that must take part in the process of simultaneous engineering - the designing engineer , the process engineer (in foundry, pattern shop and mechanical shop), the quality controller (on the side of customer and in the foundry), and the purchase department. Team work of all the partners in the process gives the optimal shape of a casting and a reliable and profitable series production as the result.
