MIS are built on the data provided by the TPS Functions of a MIS in terms of data processing requirements Inputs The highly structured information provided by these systems allows managers to evaluate an organization's performance by comparing current with previous outputs. However, within our pyramid model, Management Information Systems are management-level systems that are used by middle managers to help ensure the smooth running of the organization in the short to medium term. Management Information Systems What is a Management Information System?įor historical reasons, many of the different types of Information Systems found in commercial organizations are referred to as "Management Information Systems".Used by operational personnel + supervisory levels.Cross boundaries (internal and external).Systems for payments and funds transfers.Functions of a TPS in terms of data processing requirements Inputs TPS are ultimately little more than simple data processing systems. This data is usually obtained through the automated or semi-automated tracking of low-level activities and basic transactions. They are usually operated directly by shop floor workers or front line staff, which provide the key data required to support the management of operations. Transaction Processing System are operational-level systems at the bottom of the pyramid. Transaction Processing Systems What is a Transaction Processing System?.Using the four level pyramid model above, we can now compare how the information systems in our model differ from each other. This is often described as "the pyramid model" because the way in which the systems are arranged mirrors the nature of the tasks found at various different levels in the organization.įor example, this is a three level pyramid model based on the type of decisions taken at different levels in the organization.įour level pyramid model based on the different levels of hierarchy in the organization A comparison of different kinds of Information Systems As most organizations are hierarchical, the way in which the different classes of information systems are categorized tends to follow the hierarchy. Consequently, most attempts to classify Information systems into different types rely on the way in which task and responsibilities are divided within an organization.
However, it is important to remember that different kinds of systems found in organizations exist to deal with the particular problems and tasks that are found in organizations. Depending on how you create your classification, you can find almost any number of different types of information system. How many different kinds of Information System are there?Īs can be seen above, there is not a simple answer to this. One of the oldest and most widely used systems for classifying information systems is known as the pyramid model this is described in more detail below.
A 'type' or category of information system is simply a concept, an abstraction, which has been created as a way to simplify a complex problem through identifying areas of commonality between different things. The classification of information systems into different types is a useful technique for designing systems and discussing their application it not however a fixed definition governed by some natural law. There is a long history of classification of things in the natural world such as plants or animals, however, Information systems are not part of the 'natural' world they are created and acquired by man to deal with particular tasks and problems. Classification is simply a method by which things can be categorized or classified together so that they can be treated as if they were a single unit. The different types of information system that can be found are identified through a process of classification. How do you identify the different types of information system in an organization? It was then that the search for a way to classify information systems accurately began. However, they soon realized that in order to do this, it was first necessary to be able to define how and where the information system would be used and why it was needed. Consequently, people attempted to try to build a single system that would solve a whole range of similar problems.
However, it soon became apparent that many of the problems information systems set out to solve shared certain characteristics. In the early days of computing, each time an information system was needed it was 'tailor made' - built as a one-off solution for a particular problem.
