Using User Information Satisfaction (UIS) to Evaluate IS Success!

29 Jan

The User Information Satisfaction (UIS) is another method which can be used to measure IS Success. This is an independent variable which is linked in with the DeLone and McLean’s Model [1]. Although it is seen as being an effective method it has received some degree of criticism as “it measures success only indirectly, by assessing the quality of the IS product and related services” [2]. Some people feel this method is to narrow in assessing how to measure IS Success effectively. This is why Saarinen suggests including other aspects in this method of measuring IS Success. He outlines that the development process and how IS effects the company, should also be included. With these included he believes that it will allow for a “comprehensive and direct assessment of the IS development projects that better conforms to the idea of a traditional cost-benefit analysis, relevant to the managers responsible for the IS investments”.  UIS is one of the better known scales of measurement of IS. Many believe that user satisfaction is linked with how the success of IS is measured. By using UIS as “a dependent variable”, it connects in “the assumed causal links between high quality information, better decision making and value of the organization”. This in turn can help to achieve the measurement of IS success.

The above diagram shows how User Information Satisfaction ties in with evaluating IS Success. It is a link between Process and Product which in turn leads to IS success for a business. UIS as it stands alone is not entirely sufficient in measuring IT investments to help figure out IS success, but it is considered a valuable tool to develop in order to see what level of success exists.
