Inhaltsangabe:Abstract: Information companies are sociotechnological, targeted and open systems with at least one strategic business unit (SBU) that sells or rents (digital) information products. Operational activities are carried out in business units. Strategies define the broad directions for the system and for its subsystems. Visions are the targets of strategies, and specific, measurable, achievable, result-oriented and time-based (SMART) objectives need to be defined to give systems that possess a degree of inertia a concrete, measurable direction. In this thesis, both a bottom-up and a top-down approach to strategy will be taken. As an example for a bottom-up approach, a sequential, parallel, customer-oriented business strategy for the management of digital information products, a strategy that can be implemented through customer involvement in the product lifecycle, and through customer integration in the supply chain, will be elaborated. This strategy is best induced by a preceding timely shift towards (radical) product and process innovation, a limited punctuation of a long-term equilibrium of customer orientation and incremental innovation. Hybrid strategies like the one presented in this thesis are built on modular, independent and homogenous subsystems that communicate, collaborate, compete and finally agree on joint activities, manifested in plans that then are implemented by the actors involved in order to achieve the various primary and secondary objectives on the way towards a greater, common vision. Simultaneous hybrid strategies are a top-down or abstract view on this whole system. As simultaneous hybrid strategies possess a degree of ambiguity or even impossibility because they hide implementation details of the system, the ambiguity needs to be handled on the operational level when a hybrid strategy is implemented. Ambiguity can be resolved by introducing priorities for strategic objectives, by parallelizing strategy execution in regard to system structure, or by sequentializing strategy execution in regard to time. A top-level strategy first of all is responsibility, responsibility for the lower levels of organizational hierarchy. After the introduction, chapter 2 starts with the definition of central strategic terms. Then, the options for business strategies and hybrid strategies in the context of information companies are sketched. Chapter 3 essentially describes the theory of the product lifecycle, which can be [...]
