All four main questions need to be answered. APA formatting is not required (i.e., no abstract or cover page. But do reference your sources).

Question 1. A lot of organizations who use waterfall as their standard development methodology are looking to adopt an agile methodology instead. What are two disadvantages of waterfall? How does agile address those disadvantages and when is agile appropriate to use? Write a 400-word essay on the above questions.

Question 2. (a) Briefly describe the five duties of a systems analyst during the management of a software project.

(b) Explain what a prototype is and describe how it can be used in requirements gathering?

(c) Briefly describe four benefits of viewing an organization as a collection of systems.

(d) How is creating use cases related to requirements determination and process modeling?

Question 3. Create a use case for the following scenario. You are at a restaurant and you need a ride home. You heard about Unter...the on-demand car services company. You down load the mobile app, which supports multiple operating system versions, onto your smart phone and set up an account. Once the app is setup, you enter your pickup location and your destination address. When a nearby Unter driver accepts your request, the app displays an estimated arrival time. The driver arrives and takes you home. When you at your home, the fare is automatically and securely billed to your credit card on file with Unter. Before leaving the car, you provide feedback on the driver's performance via the Unter app. Once Unter has its commission, the remaining fare is deposited automatically and securely into the driver's account. Your trip has ended.
