Question:

You are designing a caching subsystem that temporarily stores data retrieved over the network (e.g., web pages) into a faster access storage (e.g., the hard disk). Due to a change in requirements, you define an additional service in your subsystem for configuring cache parameters (e.g., the maximum amount of hard disk the cache can use). Which project participants do you notify?
