Structure of MIS may be understood by looking at the physical components of the information system in an organization. The physical components of an organizational information system may be hardware, software, database, manual procedures and operating persons. A brief description of these components has been outlined in the following paragraphs:

Functional Information System is based on the various business functions such as Production,  Marketing, Finance and Personnel etc. These departments or functions are known as functional areas of business. Each functional area requires applications to perform all information processing related to the function. The popular functional areas of the business organization are:

The word system is derived from the Greek word “system” which means a organized relationship among the following unit or component. "A system is an orderly grouping of interdependent components linked together according to a plan to achieve a specific goal".

Conceptual design in itself is not the end of the design process, rather it servers as a basis for the detailed MIS design. The performance requirements specified by the conceptual design become inputs to the detailed design phase, in which these are further refined, detailed and finalized to be called the system specifications.

Output from a system is regarded as the main determinant of the system's performance, output from the system are affected by the input to the system.

In the conceptual design, the feasibility of meeting the management objectives for the MIS is assessed and a broad picture of the system is analyzed. It involves the following steps:

Decision-making techniques can be classified in terms of decision-making in situations of certainty, uncertainty and risk. In certainty where the outcomes are certain, no decision-making tool is required as the outcomes are certain to occur and hence anyone can take the correct decision (the obvious one). However, decision-making under risk means that the probability values associated with the success and failure of outcomes is known but the outcomes are by no means certain. In these kinds of situations, one can use the decision tree method to take decisions.

Bounded rationality is a term first coined by Herbert Simon. Simon challenged the concept of a rational man in classical and neoclassical economic theories and argued that the rationality of man is bounded by certain limitations. He opined that even though rational thinking, deductive reasoning and logic are good for solving theoretical problems.

Decisions are of varying complexity. Some decisions are routine, simple and easy to take Knowledge about such decisions is very well known. The outcomes of each alternative of such decisions are well known and certain.

The central nervous system (CNS) of our body consists of the brain and the spinal cord. Together they control most our basic functions like movements, speech, cognition, vision, etc. The human brain is a very complex system. It is made up of nerve cells called neurons. There are an estimated 50-100 billion neurons are present in an average human brain which weighs approximately about 1.5 kg. The brain is considered to consist of three main constituents:

In earlier times, the main levels of business capability and change were strategy, structure, processes and people but in today's time another level has been added to the four that already exist. This invisible asset works as a key resource for the organization.

Information plays a vital role in decision-making. Even to take very simple decisions, we need information. To understand the role played by information in decision-making, we have to understand how decisions are taken. Decision-making is basically a process that includes the following stages:

Organizational decisions differ in a number of ways. The following basis are used to classify the decisions:

Herbert Simon made key contributions to enhance our understanding of the decision-making process. In fact, he pioneered the field of decision support systems. According to (Simon 1960) and his later work with (Newell 1972), decision-making is a process with distinct stages. He suggested for the first time the decision-making model of human beings. His model of decision-making has three stages:

Ethics is a branch of philosophy that deals with what is considered right and wrong in society. It deals with issues which are not in the realm of legal or statutory domains but which may be considered conventionally right or wrong as per perception of the society of that time.

What is an Incident?

An incident in the parlance of information security is a security breach or even an attempt to breach security. An unsuccessful attempt to crack the security system is also an incident and needs to be investigated thoroughly.

we are going to discuss about the threats and vulnerabilities of information systems from both insiders and outsiders and the ways of managing such threats and vulnerabilities.



 
by Dinesh Thakur Category: Information and System Concepts

The ISO/IEC 27001 definition of information defines information as an 'asset'. Therefore, information is something that has value and requires to be protected against theft or destruction. In order to protect information from theft or destruction, all counter measures that are taken come under the purview of Information security measures. Information security is therefore defined as all steps taken by the organization to protect its information and information systems. The steps may be technical or managerial in nature and may involve automation or manual controls.
