Engineering Homework Help

The Intensive Care Unit (ICU) of a hospital wants to develop a software application or app for monitoring a
patient’s temperature, blood pressure and pulse. Each patient wears a small device, which periodically collects
measurements of these parameters and sends them to a center server. A nurse can set the lower limit and upper
limit of each of these parameters. When any of these parameters falls outside of the limits, the center server
issues a warning message and sends it to all computers and mobile devices of healthcare providers of the hospital
that are registered to receive the warning. The software running on any of these computers or mobile devices,
upon receiving the warning message, may retrieve the patient’s data from the center server, process the data,
and take appropriate action to inform the healthcare provider, such as display a message, sound an alarm or do
nothing.

What Needs to Be Done

1. Identify at least two design problems you would encounter when developing the software.

2. Identify situation-specific or Gang-of-Four patterns that can solve the design problems you identify in the
last bullet. Note: GRASP patterns are not counted.

3. Describe or explain how you would apply the patterns identified in the last bullet to solve the design
problems identified in the first bullet.
