Information Technology (IT) is always associated with Information System (IS) for they are both coordinated with manual and automated processes and management of contemporary systems.
I suppose IS/IT system flunk and break down due to its erroneous infrastructure of softwares and hardwares, unorganized and insufficient data and information, and incorrect usage and management of the system.

IS/IT systems should be well-managed, maintained and continually be developed. Failure to do so may cause malfunction and error to the system.
