The Value of Information
In order for information to be useful it must be:
  • accurate
  • up-to-date
  • relevant
  • complete
  • understandable

The accuracy of information depends on the accuracy of the data. Incorrect data will lead to incorrect information...

    G.I.G.O. = Garbage In Garbage Out    

A lot of time and effort is spent in making sure that no incorrect data is input to a system.

Businesses and organisations make important decisions based on information. They also monitor their progress, and use information to target their resources in order to make the best use of them.

Businesses will not prosper if decisions are made based on information that is not up-to-date.

Inappropriate decisions may be made if important information is missing.

If information is not understandable by the people who make decisions, then it is useless.

 

Businesses need a competitive advantage over their rivals.
The quality of information is so important that businesses and organisations are willing to spend a lot of time and money in making sure their information is good.

The cost of good information to a business will be incurred ...

  • when data is collected
  • when data is input
  • when data is processed (analysed to produce information)
  • when data is maintained (kept up-to-date)

These costs may be...

  • money - eg. salaries of workers, expense of equipment.
  • time - eg. time spent typing in data, checking data.
  • human resources - eg. allocating workers to enter data.
