T 2.3 Lack of, inadequate, incompatible resources

Not providing enough resources may significantly disrupt operation. Malfunctions may occur if the required resources are only available in insufficient quantities or if they are not provided quickly enough when needed.

Likewise, it is possible that unsuitable or even incompatible resources are purchased that cannot be used as a result.

Examples:

• Someone forgets to pay the set-up fee to the provider of a new, leased internet connection with the result that the connection is not activated. Therefore, the IT procedure which is supposed to use this connection cannot be put into operation until the connection is activated.
• An example of an unsuitable resource includes a complex and time-critical application, e.g. a graphic-intensive CAD application, which is then to be installed on a computer that is not powerful enough.
• An example of incompatible resources includes printer connection cables with varying pin assignments.
• Due to the numerous ways of exchanging data between two IT systems, it is often the case that both computers have at least three different interfaces for exchanging data, which are unfortunately not compatible. Typical questions to be asked prior to each data exchange include, for example: diskette, CD-ROM, DVD, USB stick, or Bluetooth?
• A new version of the operating system is to be installed on the workstation PCs. However, some of the existing hardware components cannot be used with the new operating system because no driver support is offered for them in the new version of the operating system.
• The memory space of the hard disks of PCs and servers, as well as on mobile data media is constantly increasing. Unfortunately, people often neglect to purchase IT components and data media with enough capacity for use as regular backup media.
