System enhancement and maintenance. Strategic data are a mix of internally generated and externally obtained information. The systematic, short-term, accurate recording of data is basic to the successful daily operation and long-term survival of the organization.

This allows the analyst to examine in detail each task being performed, each data operation, each data movement, and each data carrier a data carrier is a piece of paper, a form, a report, a worksheet, a transaction, etc. 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.

That is, they are clearly visible from observation and analysis. The benefit of this structure is that needs can be met more rapidly and more specifically, as each division can operate more or less independently for the other divisions in the company.

While management flows downward in the organization, data flows largely upward. Functions of a TPS in terms of data processing requirements Inputs. System rewrites are usually done for the benefit of, and are initiated by, the data processing community, either the data processing system developers and system maintenance personnel who need a "cleaner" system to maintain, or the data processing operations personnel who have requested operational changes to streamline the processing or to make it more efficient.

Two of the latest changes, one hardware and one a combination of hardware and software, have caused this type of multistage environment in many firms.

The system redesign and redevelopment project is the most comprehensive and difficult type of reautomation.

Knowledge Management Tools

In an organization where the systems portfolio is well developed but in a second or third phase of growth, management's informational needs are usually satisfied by reports which are little more than summaries of reports originally developed for operational people.

Usually, this data is stored in a decentralized manner which reflects the functional departmentalization of the organization. It was then that the search for a way to classify information systems accurately began. This prior automation poses a trap for the unwary analyst in that the currently used forms and documents of the business may in fact have been designed to support and accommodate an automated system.

Basing the classification on the people who use the information system means that many of the other characteristics such as the nature of the task and informational requirements, are taken into account more or less automatically. Each of the documents, transactions and process flows must be reexamined in the light of the current business environment and the current business processing needs.

Types of information In the modern 21st century business world information can be presented in different ways. Detailed logs of transactions of an organization with its external and internal customers over a period mostly form the basic ingredient of a good quality information resource.

Divisional Structure Divisional structure typically is used in larger companies that operate in a wide geographic area or that have separate smaller organizations within the umbrella group to cover different types of products or market areas.

It is at this level that the bulk of the corporate portfolio of systems is developed. OAS may be implemented at any and all levels of management. Fifth Era — Cloud computing The first era mainframe and minicomputer computing was ruled by IBM and their mainframe computers for which they supplied both the hardware and software.

They are also in charge of implementing the policies affecting the MIS either new specific policies passed down by the CIOs or CTOs or policies that align the new systems with the organizations overall IT policy.

That is to say, only the data germane to a given area can be expected from that area.

The Six Types of Information Systems and their Functions

The operational information mainly relates to current and historical performance, and is based primarily on internal sources of data. The systems support the managerial planning and control needs of the firm rather than some specific aspect of the business of the firm.

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. MIS can help a company gain a competitive advantage.

The tactical information is generally predictive, focusing on short-term trends. In some cases, the immediate enhancement or maintenance project will require data which should logically be captured by a different, unrelated application.

Four level pyramid model based on the different levels of hierarchy in the organization A comparison of different kinds of Information Systems Using the four level pyramid model above, we can now compare how the information systems in our model differ from each other.

Since such activities are controlled at lower levels of management, operational information is needed by the lower management. Many of the forms and transaction flows within this type of environment are automated or semi-automated.

These flows may have been structured to accommodate the needs of the then prevalent technology rather than the needs of the business. They may merely need to be refurbished, or they may need to be scrapped entirely in favor of a new and more streamlined processing flow.

Information Management The business of information which is today a multibillion dollar industry first started when a firm called Bloomberg started compiling important information about US companies and their balance sheets and selling them to stock brokers. There are many types of accounting information systems and, as a result, they vary greatly.
