Quiz since some questions are problem solving related, you may answer the problem solving questions inline or by doing it on paper (especially activity diagram) and take a camera picture or use visio or lucid chart or any similar diagramming tool and upload the exported file as a PDF file.

True False Question 3 1 pts 1/22 In the Scrum process, a Product Owner role guides everyone including stakeholders on the Scrum Process.

(a) Write three user stories without ambiguity. Make sure you follow a standard userstory template. (6 points) (b) Also provide examples of interaction design using either one of these threeprinciples: SAC, FeVER or CAP principles in context of the user story specific to job matching. (4 points) 17/22 Edit 12pt View Insert Format Tools Table Paragraph p Question 28 0 words 10 pts 18/22 Think on your feet for this problem. It is an open-ended question. :) Use your own creativity and ingenuity in answering this question. Assume you just got promoted as a manager of a digital clock manufacturer. You got this job as an expert of the Spiral, RUP and Agile process models with focus on risk assessment and mitigation. The digital clock manufacturer decides to use a graphical hour handle and a graphical minute handle. The Manufacturer also decides to show the time digitally with the hour, minutes and seconds at the same time. The manufacturer decides to synchronize with an atomic clock to display the graphics correctly, while the digital display of time is displayed with an internal hardware timer. Incorporating Risk in the software process model is key to success. Use your creativity and create a Risk Management Matrix (explained below) for highly predictable (have high probability of occurring) and less predictable risks (have low probability of occurring) 19/22 with solutions on how you will handle the risks. You may include a few risks general to any problem and a few problem specific risks. Categorize them under People, Process and Product. Limit the number of risks to a combined total of 5 risks and describe how you propose to handle each one of the risks. Here is what the risk management matrix should contain. The matrix must consist of columns for Predictable and Unpredictable risks and rows for People, Process and Product and an additional column for how you will handle the risks. You do not need to be perfect with your risks and how you will handle them. You must clearly categorize under predictable and unpredictable and people, process and product. Note that the total for both predictable and unpredictable cannot be more than a total of 5 risks. ( 5 * 2 = 10 points). Predicatable UnPredictable Solution to handle risk People risks (state one or more) Process risks (state one or more risks) Product risks (state one or more risks) Edit 12pt p View Insert Format Tools Table Paragraph 0 words 20/22 Question 29 10 pts Create an Activity Diagram for the following problem: (10 points) Select a chocolate, a chips pack and a coke bottle from a vending machine. If the item is available in the machine, add the item to the cart and add the price of the item to total_price. Else, skip that item and add only available items . Pay the total amount of the cart using bills and return the change and exit the transaction. Also answer one of the two below questions for the above example: (a) What classes will you need in a class diagram? How will you connect theseclasses with implement and inheritance arrows and aggregate and association relationships? Draw a class diagram with the classes you came up with. OR (b) Draw a sequence diagram for the high level operations (you may ignore minordetails). Upload Choose a File Question 30 0 pts This is a bonus question for 5 points. Please provide three user stories for any single project and categorize them under any three of the MOSCOW principle for user stories. (you will be required to read and understand on your own, the User Stories PowerPoint in your class slides material to do this) Edit 12pt View Insert Format Tools Table Paragraph 21/22 p 0 words 22/22

19. Simplicity in software engineering has more benefits for software maintainers than it has for
users of the software. If the software is complex at the design level, its implementation is
going to be complex and this means that maintaining the code is also going to be much
difficult. The on-boarding process is becoming a strenuous one for new developers too. As
software developers, we should ensure that software is designed to be simple so that we do
not fall into these huddles.
20. Static models are used to define the structure of the system, they do not change over time.
These includes class-diagram and composite structure diagrams which could include,
component diagrams and deployment diagrams. On the other hand, dynamic models are
used to elaborate the dynamic behavior of the system, they exhibit the behavior of the
system. This includes collaborations among components and change of state from one to
another. Dynamic models include activity diagrams, state machines, and sequence diagrams

ii. Resource
iii. Planning
iv. XML
v. Git
22. Feedback is where after user experiences how the system is working, they give feedback
on how satisfied they are with the feature and what they would like improved. The team
then agrees with the customer and the improvement is done.

23. In the incremental model, work is sliced into multiple small sizes called increments, each
increment builds to the previous increment previously delivered. The software hence grows
overtime. In the iterative m...
