a. Explain why professional software that is developed for a customer
is not simply the programs that have been developed and delivered.
b. Explain why the fundamental software engineering principles of process, dependability, requirements management, and reuse are relevant to all types of a software system.
c. In a hospital, patients will often have numerous different measurements taken which record their condition over a time period. Different patients will have different measurements taken (depending on their specific treatment). The hospital will potentially have thousands of quantities of different phenomenon types (such as height, weight, blood glucose level, heart rate, blood pressure, liver performance, lung capacity, white blood cell count, red blood cell count, etc.), which need to be recorded. Each patient observation can be for a quantitative amount/quantity (such as the patient's height) or for a qualitative category observation (such as a written report by the doctor or nurse) for a given category.
Draw a Type diagram to represent the different measurements that can be taken for a single patient. Your diagram should contain the following Types: Patient, Measurement, Quantity, Observation, Phenomenon Type, Category Observation and Category. Your diagram should include the cardinality that exists between associated types and make use of complete and incomplete partitions where necessary.
d. Briefly discuss why it is usually cheaper, in the long run, to use software engineering methods and techniques for software systems.
