Consider how such sources of information may be extracted from the environment and how reliable these information sources are.
Internet sources e.g. Stock level or inventory level, database –required by the lower level management – more for operation
External sources e.g. economics outlook of a country – required by the highest level of management – more for planning purpose
Primary sources of information

7. Timeliness – information has time values – information that is current, the values increase. On the other hand, information that is older, the values decrease.
4. Are these desirable characteristics different at each level or are there any common desirable characteristics?
What is the significance of detailed versus consolidated data to management at the different levels of management?
