5.1.9 Difficulties in prediction

When a system is complex and continuous changes are occurring, prediction becomes difficult. Time and money are often the main constraints. Sometimes, predictions which provide information for decision makers may be complicated and not clear cut. There are often a range of methods that may be used to predict a particular change and these may vary depending on the complexity of the change.
