What factors should be assessed to understand the relationship between a system and its environment?
Answer: The following factors should be assessed to evaluate the relationships between a system and its environment:

1. The number and complexity of system interfaces: The larger the number of interfaces and the more complex these interfaces, the more likely it is that interface changes will be required as new requirements are proposed.

2. The number of inherently volatile system requirements: Requirements that reflect organizational policies and procedures are likely to be more volatile than requirements that are based on stable domain characteristics.

3. The business processes in which the system is used: As business processes evolve, they generate system change requests. The more business processes that use a system, the more the demands for system change.
