CONCEPTUAL VIEW OF MIS

The concept is a blend of principles, theories and practices of management, information and system giving rise to a single product called MANAGEMENT INFORMATION SYSTEM.

The concept of management gives high regard to the individual and his ability to use the information. MIS gives information through data analysis. While analyzing the information, it relies on many academic disciplines like management science, OR, organization behavior, psychology, etc.

The foundation of MIS is the principles of management and its practices. MIS uses the concept of management control in its design and relies heavily on the fact that the decision maker is a human being and is a human processor of information.

A MIS can be evolved for a specific objective it is evolved after systematic planning and design. It calls for an analysis of business, management views and policies, organization culture and the management style.

The MIS,therefore relies heavily on systems theory.The systems theory offers solutions to handle complex situations of the input and output flows. it uses theory of communication which helps to evolve a system design capable of handling data inputs, process, the outputs with the least possible noise or distortion in transmitting the information from a source to destination.

Simulation Practice Problems

1. There is only one telephone in a public booth of a metro station. Following table indicates the distribution of arrival time and duration of calls: Time Between arrivals (minutes) 4 5 6 Probability 0.1 .6 0.3 Call Duration (minutes) 3 4 5 6 Probability 0.14 0.6 0.12 0.14 Simulate for 100/500/1000 times. Conduct 3 such trials. It is proposed to add another telephone to the booth. Justify the proposal based on the waiting time of caller.Generate graphs to support your answer. 2. A baker needs to find out the cookies he need to bake each day. The probability distribution for the cookies customers is as follows: Number of customers/day 7 9 11 14 Probability 0.35 0.30 0.15 0.20 C...

System Analysis and Design (SAD)

Introduction to System Analysis and Design (SAD) System are created to solve Problems. One can think of the systemsapproch as an organised way of dealing with a problem. In this dynamic world , the subject system analysis and design, mainly deals with the software development activities. This post include:- What is System? What are diffrent Phases of System Development Life Cycle? What are the component of system analysis? What are the component of system designing? What is System? A collection of components that work together to realize some objectives forms a system. Basically there are three major components in every system, namely input, processing and output. In a system the different components are connected with each other and they are interdependent. For example, human body represents a complete natural system. We are also bound by many national systems such as political system, economic system, educational system and so forth. The objective of the system demands tha...

Advantages and Disadvantages of EIS Advantages of EIS Easy for upper-level executives to use, extensive computer experience is not required in operations Provides timely delivery of company summary information Information that is provided is better understood Filters data for management Improves to tracking information Offers efficiency to decision makers Disadvantages of EIS System dependent Limited functionality, by design Information overload for some managers Benefits hard to quantify High implementation costs System may become slow, large, and hard to manage Need good internal processes for data management May lead to less reliable and less secure data
