Under what condition should the 'replace all or part of the system with a new system' option be chosen?
Correct Answer
When factors such as new hardware mean the old system cannot continue, or off-the-shelf systems allow reasonable-cost replacement
Explanation
Replacement should be chosen when factors such as new hardware mean the old system cannot continue operating, or when off-the-shelf systems would allow a new system to be developed at reasonable cost. An evolutionary replacement strategy can replace major components with off-the-shelf systems while reusing others.
