4 Level pyramid model diagram - Information systems types

A four level pyramid model of different types of Information Systems based on the different levels of hierarchy in an organization. The first level represents transaction processing systems for workers. The second level represents management information systems for middle managers. The third level represents decision support systems for senior menegers. The fourth level represents executive information systems for executives.
"The "classic" view of Information systems found in the textbooks in the 1980s was of a pyramid of systems that reflected the hierarchy of the organization, usually transaction processing systems at the bottom of the pyramid, followed by management information systems, decision support systems, and ending with executive information systems at the top. Although the pyramid model remains useful, since it was first formulated a number of new technologies have been developed and new categories of information systems have emerged, some of which no longer fit easily into the original pyramid model.
Some examples of such systems are:
data warehouses,
enterprise resource planning,
enterprise systems,
expert systems,
search engines,
geographic information system,
global information system,
office automation." [Information systems. Wikipedia]

"At the base of the identity of an organisational is its organizational culture. A culture is comprised of the shared values, customs, traditions, rituals, behaviours and beliefs shared by a social group (national, ethnic, organizational, etc.). Cultures also share languages, or ways of speaking. From a communication perspective, cultures are made and remade through the words we use to describe our world. Culture represents a common set of values (“shared meanings”), shared by members of a population, a organization, a project/ programme purpose unit or a profession (e.g., engineers versus scientists). Culture change with the times but the speed at which the culture of different institutions change varies widely."
