As a manager, in what specific areas do you make use of data within the organization in decision making?

An MIS can produce a number of different types of reports. A scheduled report is produced on a regular interval, such as every day, week or month. For example, a manager of a production floor may want to see weekly payroll reports to keep track of labor costs. Reports typically focus on a number of key indicators, such as inventory levels, production activity or sales volume.

Often, these indicators are compared to numbers from prior reporting periods or to targets set by the organization. This gives mangers the opportunity to implement any corrective actions where necessary.

An on-demand report is only produced by request instead of on a fixed schedule. Such reports are typically produced when a question arises regarding the status of a particular item or production element. For example, consider a shipping company that picks up, ships and delivers thousands of packages every day. If you ship a package, you get a tracking number that you can use to get the status of that package. When you log in to the website and enter the tracking number, you are requesting an on-demand report.

An exception report is automatically generated when a situation is unusual and requires some sort of attention. For example, consider a manufacturing plant with several production lines. All lines are expected to generate a certain volume. An MIS could generate an exception report if these are not met. Exception reports rely on trigger points. These are parameters set up by managers that would result in an exception. In the case of the production lines, the trigger point could be something like10% below expected production.

As Mr. Moinul Islam answered ... Data as information is part of any decision making strategy. You need to use information in order to make a good decision ... Unless you meant something else by data !

I fully agree with the answer been added by MR  Moinul Islam...................Thanks.

Data (and information) is an integral part of any decision making process. A decision is warranted because of some development.  And effective decision would be possible if and only if correct data or information is available about the situation…..

And I must say that any decision taken without meaningful data (and information) is meaningless and can prove futile as well, in most of the cases .
