Further Causes & Categories Of I.S Failures

5 Mar

An Information System can be defined as a failure when some of the following situations occur:

– When the system as a whole does not operate as expected and its overall performance is sub-optimal.

-If on implementation, it does not perform as originally intended or it is user-hostile.

– If the cost of development exceeds any benefits the system may bring throughout it’s lifecycle.

There are certain types of I.S failures and they are characterised as Correspondence failures, Process failures, Interaction failure and Expectation failure. A correspondence failure is when system design objectives are not met, correspondence failure tend not to recognise users may not necessarily accept systems that meet design objectives and specifications. A process failure is when a system cannot be developed within an allocated budget, and/or time schedule. It is also when a system is met with massive overspending in time and cost. An interaction failure is when the level of end-user usage of the information system is suggested as a surrogate in IS performance measurement. Finally expectation failure occurs when the inability of a system to meet its stakeholder’s requirements expectations happen.

These are four major categories of I.S failure and can be avoided very easily.
