It is true, that in a management information system, the quality of information is determined by its usefulness to users, and its usefulness determines the success of the information system.
Explanation:
A management information system (MIS) is a computerized and centralized database that collects data from many different resources in the organization. And, then processes and organized the data in a way that would be useful and helpful in making a business decision. These days, for both large and small organization, collection of data and use of technology are so prevalent and these organization collecting the data from their businesses resources daily even hourly such as daily sale, daily expense, hourly wages, etc, and then managing it in a way to make a right business decision. A good MIS in an organization gives a competitive advantage because it turns the data into usable and into helpful information that can be used in making business decisions and strategy and to increase profit.
However, the information quality is based on its usefulness to the user or to the organization. Because if the MIS produces the information that is not useful to the user, the information and use of MIS are useless in the organization because the information that is required in making a business decision is not useful.
If the MIS produces the quality information to its user in making the right business decision and organization or user take the right decision that brings profit to the organization. Then, this use of information determines the success of an information system in an organization.
For example:
In a Bakery, the MIS produce the right information in making decision e.g. MIS produce information to bakery owner that on valentine day, most people buy chocolate. Then, the owner tries to meet the demand for chocolate on valentine's day. Therefore, this is the quality of information and it is determined by its usefulness to the bakery owner and its usefulness determines the success of MIS.
