Change prediction<br />
●<br />
●<br />
●<br />
Predicting the number of <strong>change</strong>s requires an<br />
understanding of the relationships between a system<br />
and its environment.<br />
Tightly coupled systems require <strong>change</strong>s whenever<br />
the environment is <strong>change</strong>d.<br />
Factors influencing this relationship are<br />
• Number and complexity of system interfaces;<br />
• Number of inherently volatile system requirements;<br />
• The business processes in which the system is used.<br />
