Coming from Hubert Dreyfus’ recent book ‘‘Retrieving Realism”, the paper presents embodied pre-conceptual perception and representational cognition as two contrasting perspectives on accessing the world. It further characterises the ‘different forms of knowledge emerging from these perspectives and how they dynamically relate to each other. Taking up the Peircean theory of signs and abductive reasoning as methods of discovery, computers are analysed as semiotic machines that formally model and objectify explicit knowledge about social practices and that can be embedded in (...) the sign processes of thereby restructured practices. This practice theoretical perspective allows for both, understanding the limits of AI and pointing to options for productively combining the performance of ‘‘cognitive artifacts” with the tacit skills of knowledge workers.

Looking back on the development of computer technology, particularly in the context of manufacturing, we can distinguish three big waves of technological exuberance with a wave length of roughly 30 years: In the first wave, during the 1950s, mainframe computers at that time were conceptualized as “electronic brains” and envisaged as central control unit of an “automatic factory”. Thirty years later, during the 1980s, knowledge-based systems in computer-integrated manufacturing were adored as the computational core of the “unmanned factory”. Both waves (...) dismally stranded on the contumacies of reality. Nevertheless, again thirty years later, we now experience the departure of the “smart factory” based on networks of “artificially intelligent” multi-agent or “cyber-physical systems”. From the very beginning, these technological exuberances rooted in mistaken metaphors describing the artifacts and, hence, in delusions about the true nature of computer systems. The behaviour of computers is, as computing science teaches us, strictly restrained to executing computable functions by means of algorithms, it thus neither resembles the performance of a brain as part of a complex sensitive living body nor is it in any meaningful sense “knowledgeable” or “intelligent”. When the delusion of being able to implement “smart factories”, despite the countless accomplishment failures before, gains momentum anew, it appears absolutely essential to reflect on underlying misconceptions.

Contrary to common belief, IT systems often disappoint the expectations to increase productivity and flexibility of work and value creation processes. Moreover, most IT design and implementation projects still fail or burst time and cost budgets to a high extent. After presenting significant empirical evidence for these phenomena, the paper reflects on the reasons for their persistence by developing a semiotic perspective on the processes of dealing with computer artifacts in organisations. This semiotic view allows understanding the processes of designing, (...) implementing and using IT systems as efforts of structuring social practices in organisations. A typical case of enterprise resource planning system implementation illustrates this. Finally, a number of guidelines for an improved practice of designing and appropriating IT systems for effective use in organisations are derived from the theoretical reflections. (shrink)

Profound changes in world markets are resulting in conflict between traditional structures of production and new market requirements. The right answers to this challenge are heavily disputed. One option is to replace human work still further by artificially intelligent technology without changing basic structures of production. In contrast to this strategy, alternative production concepts seek to combine the unique human capabilities of perception, evaluation and decision making in unstructured situations with appropriately designed computer systems. Empirical evidence from the use of (...) NC technology indicates that sensual experience and practical knowledge are necessary ingredients rather than disappearing residuals of efficient production. By far their tacit dimension does not allow complete transformation into objectified, scientific knowledge. In the field of metal cutting it is the skilled workers themselves who constitute the primary source of productivity. In order to overcome their traditionally problematic and uncomfortable working situation, shop-floor programming methods have been developed that are adapted to their concrete and graphic mode of thinking and acting. These allow workers to make their own efficient NC programs, thus maintaining their practical competence. This paper illustrates a necessary new perspective in system design: away from developing computer programs for imitating and replacing human expertise and towards designing computers as a useful tool for human experts.

Inspired by an economic interpretation of the Faustus drama allegorically disclosing the ‘alchemical’ nature of modern economy, the paper presents a critical view on the development of technology as concomitant phenomenon of work practices with particular focus on manufacturing. It starts with a theoretical perspective on the dynamics of creating explicit propositional knowledge and its re-appropriation for practical use. This lays the ground for understanding how technical artefacts emerge from and, in turn, affect social practices. It further helps to understand (...) the development of human reflective action competence and working capacity as most relevant forces of production in complex and dynamic market environments. These relationships are exemplified in some detail by looking at the problematic development and use of IT in manufacturing’s value creating processes. The paper finally advocates reflective attitudes and evolutionary procedures as basic principles for designing useful and useable IT systems according to human needs and for protecting oneself from the Faustian omnipotence delusion of endless and effortless wealth creation.
