T 2.3 A lack of compatible, or unsuitable, resources

Insufficient provision of resources can disrupt IT-related operations considerably. An insufficient amount of required resources, or failure to provide them in due time, can result in a discontinuity of service.

Similarly, it may happen that unsuited or even incompatible resources are procured which consequently cannot be used.

Examples:

• The forthcoming transition to the year 2000 can cause compatibility problems in the hardware and software used.

• For a newly leased Datex P line the payment for the installation initially fails to be transferred to the network operator and the connection is therefore not enabled. As a result, commissioning of the IT procedure intended to use this line is delayed.

• An unsuitable resource is, for instance, a graphical user interface that is installed on a computer with insufficient performance.

• An example of incompatible resources are interconnecting cables of varying pin assignment for connecting printers.

• The main memory or hard-disk space on a computer is not sufficient to allow the operation of a database using new standard database software
