Techniques For Managing Information Overlord SUMMARIZIN G FILTERING INFERENC ES MESSAGE ROUTING

Summarizing It’s is one of the method used for improving communication. Summarization is a commonly used method of data reduction and it refers to the reduction of data to a meaningful and concise form. For example, each employees gross pay and taxes are accumulated from the beginning of the year may now be summarized and printed summarization reduces the amount of data transmission without changing the essential meaning of the original message. Accounting classification is a formal method of data summarizing.

Filtering/ Message Modification An important method used to exercise control over information transmission is message modification of filtering. It refers to the removal of unwanted and irrelevant data so as to make the information more useful to the recipient. Under this method the meaning of the message is altered before it is transmitted. when information is passed from lower level to the higher level in the organization structure. It is the process whereby a manager selectively accepts that much input, which his mental ability can manage to process.

Methods Of Modification EXAMPLE CONTENT The frame of reference by using knowledge and experience Period, product, market segmentation, decision rules or procedures. Ignore the past data , consider only some products. select only the relevant market segments Universally acclaimed normal decision procedure. Break even analysis, methods offixing inventory levels. Ignores the intangible factors. Ignore the demand variation based onexperience. METHOD

Inferences are drawn from a large volume of data and these inferences are transmitted or communicated in the organization instead of original data. This process reduces the volume of data considerably. The quality of inference depends on the ability and skill of the person who make the inference.

Message Routing Message routing is another method of improving the degree of communication. The principle here is to distribute the information to all those who are accountable for the subsequent action or decision in any manner. Message routing principle achieves the spread of information to the appropriate quarters. The message should be distributed to only those persons or departments which really require information to make decision or initiate an action. For example, copies of purchase order should be sent to production, distribution and billing sections because these departments have to take direct action based on this order.
