The term IT (information technology) that is popular today is part of a chain of long term developments in the world of SI (System Information). An information technology system is basically built on five levels in a pyramid of STI (Information Technology Systems). Depth is a question of basic concepts, technologies, applications, development, and management.
Information technology system is a system that is formed in relation to the use of information technology. Component of the information technology system was 3, which hadware (hardware), software (software), and brainware (human).
In the information technology systems, both complex and simple, the goal is to produce the information. An existing information systems information technology can be said to be useful if sustained by three things right on their needs (relevant), just in time (timeliness), and the exact value (accurate). If the information in the information technology systems are not supported by the third case, the information in it is useless.
In general, the information on the STI (Information Technology Systems) is divided into 3 types. The breakdown is as follows.
1. Information Data Collection
This information is information that takes the form of accumulation (data collection) to answer questions. Within an organization, this information is very useful for lower-level managers to evaluate the performance of its employees.
2. Steering Information Caution
This information is information that is used to focus attention on issues that deviate, inefficiency, or irregularities. Deviation here can be over-budget costs, which have not achieved the sales target, the company’s revenue decline, increased production costs, and others.
3. Troubleshooting Information
This information is information that helps decision-makers to solve the problems being faced. Problems here are the problems that require repeated analysis of the top-level management.
