Fixed Data Structure for Key Decision Factors

Each key decision factor is an object with:

• a localizable description (displayed as the name of the key decision factor);
• a value which changes over time such as a person's income (optional); and
• a list of named key events such as a person's date of birth (optional and described in more detail below).

Typically each key decision factor uses exactly one of these optional features - i.e. the key decision factor is centered around a value which changes or a list of key events. It is possible to combine both features if you require. (Technically it is also possible to use neither feature; however, such a key decision factor would not be displayed and would be somewhat pointless.)
