Q1. b. What are the functions and disadvantages of MIS?Answer:

Advantages and Disadvantages, which we feel, is appropriate in the case.1) To begin with, in the above Case presentation, the initial paragraph is on the typical work scenario faced by aManager in most of the service sector organization. The amount of pressure he is in during his daily routineswork. Here he seems to be senior most and most computer literate among others in the office. Hence his bosscomes to him and hands over a letter to him, which mentions about Collaboration over Internet. The manager issupposed to go through the contents and brief everyone by Thursday. Thematter is related to E-Collaboration and E Business. Further there are information on how to get more informationon E-Collabration. There are references of various Internet sites given to gather more inputs on E-Enterprise, EBusiness and E Collaboration. E business systems lay foundation of other Enterprise applications, namely Ecommerce, E-communication and E collaboration.To understand and discuss about the above terms we need to know that MIS has been evolving in different formsunder different levels of management. Some of the developments are recent and some are still in the developmentstage. The research continues. With the emergence of Internet, business organization has undergone structural,cultural, and qualitatitive change and a new organization structure has emerged which is known as E businessenterprise.

They can be at different locations and form a virtual team to work on project or assignment.E-collaboration uses E-communication capabilities to perform collaborative tasks, or project assignment. Itseffectiveness is increased by software 'GroupWare' that enables the members of the group to share information,invoke an application and work together to create documents and share them and so on. GroupWare iscollaboration software. E-collaboration helps work effectively on applications like calendaring and schedulingtasks, event, project management, workflow applications, work group applications, document creation andsharing, and knowledge management.E-collaboration system components are Internet, Intranet, Extranet and LAN, WAN networks for communicationthrough GroupWare tools, browsers.
