• Understand that ICT systems offer fast repetitive processing, vast storage capability, the facility to search and combine data in many different ways which would otherwise be impossible. This can provide quality information.
   

• Understand that the response speed of technology within ICT systems facilitates the use of feedback, e.g. maintenance of optimum stock levels, electronic fund/money management systems.
   

• Understand that there are limitations in the use of ICT systems and in the information they produce. Factors could include hardware, software and communications limitations in addition to inappropriate data models and data control mechanisms.
