a$)$ You are in charge of five software development projects. The project characteristics of each of

the system are as follows:

$$ Project $1.$ Web$-$site for a local company. Relatively small system. Requirements are vague and

likely to change in the near future.

$$ Project $2.$ A very large embedded system whose requirements can be easily identified and are

relatively stable.

$$ Project $3.$ A $$standard$$ business application. You have developed similar systems in the past.

$$ Project $4.$ A relatively complex administrative system for one of the local hospitals. Some of

the requirements seem to be pretty vague, but all the requirements are stable.

$$ Project $5.$ A small real$-$time control system to be used for monitoring patients in a local

hospital.

Which software development approaches$/$models would you choose for each of your projects?

Justify your choices using diagrams and detailed explanations.

b$)$ Software engineers are concerned with the usability of the interfaces they design. Several

interface factors can be assessed. Explain the factors listed below from the end user$$s

viewpoint.

i$.$ Learnability

ii$.$ Speed of operation

iii. Robustness

iv$.$ Recoverability

v$.$ Adaptability

c$)$ Explain the principles of developing a user centered design.

d$)$ Write a sample Software Requirements Specification $($SRS$)$ document for a system of your

choice.
