“S-, P-, or E- Systems” Please respond to the following:
• From the e-Activity, identify at least two methods by which we can
determine if a legacy system should remain as legacy or it should be
upgraded into a new software system. Explain these two methods and how
they are applied.
• From the e-Activity, describe at least two ways software engineers can measure the impact of a proposed change to a software system.
“Cost of Strongly Coupled Components” Please respond to the following:
• Explain why a high degree of coupling among components of a
software system can make maintenance of the system difﬁcult. Provide at
least one example that supports your answer.
• Elaborate on two maintenance strategies that you would apply to
lessen the effect of an already tightly coupled software that you have
to maintain for an organization that requires 100% uptime on its
safety-critical system. Provide a justification as to why you would
implement these strategies over other options that are available.
Describe how your strategies would change if the system only required
90% uptime and could be shut down for short periods of time during
