Business Information Systems 1 1_Information processing perspective of organization theory 20/02/2023_1 Definition of information system A technology represents a process (or a set of processes) that a given organization can perform, together with all the resources needed to perform the process (skills, tools, etc.). A technology has a 1 1 relationship with a machine. It is a set of processes + all the resources including the machines. A technology is what the organization can do (car, pc, webcam). It is not necessary a machine. A technical system represents a set of machines supporting a given technology, a set of processes. If we apply these 2 concepts to a particular type of technology, which is an information technology, we have that: An information system corresponds to the concept of technology that is a set of coordinated processes producing an information output and executing information processing activities. It is a subset of technology. An information system corresponds to the concept of technical system that is a technology, an IT architecture is a technical system supporting a given information system. The difference between a T and a TS is that a T is a set of processes and all the resources including the machines, while a TS is a set of that machines. The difference between a IS and a ITA is that a IS is the concept of information technology, so it is a set of processes, while an ITA is a technical system supporting a given information system. Organizational impact of technical systems Traditional debate on how innovation changes the technologies, the processes, in a technical systems. That debate has come out on a set of consolidated beliefs (principles) on how technical innovation impacts with organizational change. These consolidated principles are for non-IT technical systems, they come from traditional organization theory:  Technical innovation increases organizational efficiency (not effectiveness). In a simple input-output model (process): The efficiency is when we have more output than input (if the output increses the efficiency increases, if the input decreases the efficiency increases). A major of efficiency is some major of output/some major of input. For example time/n° pieces produced. The effectiveness is the ability to reach a goal. To give a definition we divide the output between the objective output and the actual output that has been reach. Effectiveness can be majored as the actual output/objective output. In organization theory the idea that objective output should be ambiscious has an economic foundation. If you're not ambiscious someone else will be more ambiscious and they will get more than you. In economic terms it means that another company will become bigger than you and it will pull you out of the market. Traditionally no-one taks about effectiveness and manager thinks that technology can make increase the efficiency of a company, not the effectiveness (ability to be ambiscious). Of course
