Long term plan essential for Management Information System?

In case you happen to be doing a homework for eLearning(Amity)...my guess is:

A long-term planning for MIS is essential as it's focus is strategic in nature, and are long term in nature and hence it's development and budgeting has to be planeed for if MIS is to be used and expanded but some parts are also medium term as in tactical, and short term as in operational. Without a long term plan integrating MIS of all three levels is difficult. Since business plan are by nature long term, its integration with MIS and its support to strategic nature is also long term. MIS is very much part of a business operation as it is like any long term assets, such as building and equipment. Without information or MIS, a transaction, plans required to managed becomes very difficult to compete in today's world without information.
