INFORMATION CONCEPTS

What do you mean by information?

Information means any material in any form that

is related to administration, operations or

decisions of a public authority

INFORMATION CONCEPTS

The word `information is used commonly in our day today working. In MIS, information has a precise meaning andit is different from data. The information has a value indecision making while data does not have. Information bringsclarity and creates an intelligent human response in the mind.

In MIS a clear distinction is made between data andinformation. Data is like raw materials while the informationis equivalent to the finished goods produced after processingthe raw material. Information has certain characteristics.

These are: Information

Improves representation of an entity

Updates the level of knowledge

Has a surprise value

Reduces uncertainty

Aids in decision making

The quality of information could be called good or baddepending on the mix of these characteristics.

FRAME WORK

For defining MIS organization and itscharacteristics, it is necessary to understand and

general framework which seeks to sharpen

important distinction in type of informant

that supports managerial decisions.

ROBERT ANTHONY in 1965 suggested that thearea of management planning (deciding what to

do ) and control (assuring desiring results) be

divided into three categories.

>> STRATEGIC PLANNING,>> MANAGEMENT CONTROL &

>> OPERATIONAL CONTROL

BUSINESS MODEL

Abusiness model describes the rationale of how

an organization creates, delivers, and captures

value - economic, social, or other forms of value.

The process of business model design is part

of business strategy.

In theory and practice the term business model is

used for a broad range of informal and formal

descriptions to represent core aspects of business,

including purpose, offerings, strategies,

infrastructure, organizational structures, trading

practices, and operational processes and policies.

BUSINESS MODEL DESIGN TEMPLATE

Formal descriptions of the business become the

building blocks for its activities.

Many different business conceptualizationspropose a single reference model based on the

similarities of a wide range of business model

conceptualizations. With his business model

design template, an enterprise can easily describe

their business model


13/13

CONCEPTUAL MODEL

In the most general sense, a model is anything

used in any way to represent anything else.

Some models are physical objects, for instance, a

toy model which may be assembled, and may even

be made to work like the object it represents.

However a conceptual model, may only be drawn

on paper, described in words, or imagined in the

mind. They are used to help

us know and understand the subject matter theyrepresent.
