Shadow IT is a term often used to describe information-technology systems and solutions built and used inside organizations without explicit organizational approval.

Shadow IT  is also used to describe solutions specified and deployed by departments other than the IT department.

Shadow IT is considered by many an important source for innovation and such systems may turn out to be prototypes for future approved IT solutions.
On the other hand, shadow IT solutions are not often in line with the organization's requirements for control, documentation, security, reliability, etc., although these issues can apply equally to authorized IT solutions.
