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]

"The Project Management Triangle (called also Triple Constraint or the Iron Triangle) is a model of the constraints of project management. It is a graphic aid where the three attributes show on the corners of the triangle to show opposition. It is useful to help with intentionally choosing project biases, or analyzing the goals of a project. It is used to illustrate that project management success is measured by the project team's ability to manage the project, so that the expected results are produced while managing time and cost."
