You have been hired by a company that say they have tried to implement the Extreme Programming methodology exactly. You walk into the workplace and see a maze of cubicles. As you walk around the workspace and peek into cubicles, you see pairs of programmers working together. You pop into a cubicle and ask the developers where you can find the client. One developer hands you a business card that has the client’s phone number on it. He said you can leave a message there and the client will get back to you. You go into the next cubicle and ask the two programmers working there when the next release is due. They tell you that releases are due every 2nd Friday. They have a release coming up this Friday. You ask these programmers what they are working on. They explain that they are the database team, and they exclusively work on maintaining and building the database. You realize that there are many areas of Extreme Programming that they are not following properly. What are some areas of development you are going to need to change in order to have Extreme Programming running precisely in this office?
- A.
The workspace
- B.
Pair Programming
- C.
Client Availability
- D.
Small, Frequent Releases
- E.
Developer Versatility
Correct Answer(s)
A. The workspace
C. Client Availability
E. Developer VersatilityExplanation
In order to have Extreme Programming running precisely in this office, some areas of development that need to be changed include the workspace, client availability, and developer versatility. The maze of cubicles does not promote effective communication and collaboration among team members, so a more open and collaborative workspace should be implemented. The fact that the client can only be reached through a phone message indicates a lack of direct and immediate communication, which goes against the principles of Extreme Programming. Additionally, the fact that the developers are exclusively working on the database suggests a lack of versatility and cross-functional collaboration, which is another important aspect of Extreme Programming.Rate this question:

Let’s say your team is developing a mobile app that allows users to search for food and drink specials at local restaurants.The ‘sprint goal’ for this iteration is to set up the user interface. This is everything that the enduser will see and interact with. Halfway through development for the iteration, the client sends you an email that they’ve changed their mind and they want the main colors of the application to be blue and white instead of red and black. This is a quick fix for the development team. The client also requests that they want the application to now support ads that pop up on the screen. Which of these changes can be made in the current iteration?
- A.
The color change
- B.
Popup ads
- C.
Both of them
- D.
Neither of them
Correct Answer
A. The color changeExplanation
The color change can be made in the current iteration because it is a quick fix that can be implemented without major changes to the user interface. It does not require additional functionality or significant development effort. On the other hand, adding popup ads would require implementing new functionality and modifying the user interface, which may not be feasible within the current iteration's timeframe. Therefore, the color change is a more realistic and achievable change to make in the current iteration.Rate this question:

“When needed” manufacturing
- D.
“Lean” manufacturing
Correct Answer
B. “Just-in-time” manufacturingExplanation
Just-in-time manufacturing is the term from the manufacturing industry that inspired the philosophy in Kanban to only do one thing at a time, when it is needed. Just-in-time manufacturing is a production strategy where items are produced and delivered just in time to be used, reducing waste and inventory costs. This philosophy aligns with the principles of Kanban, which emphasizes the importance of limiting work in progress and focusing on completing tasks as they are needed.Rate this question:

You are developing a software product for a client that connects a mobile app to a database. Each of these components has a basic set of features and an advanced set of features that can be built on top of the basic features. The mobile app depends on the database in order to be released, but a proof-of-concept mobile app can be made with just the basic features and no database connection. According to just-in-time manufacturing, what is the best strategy for developing the product? You should develop...
- A.
All features of the database first, then all features of the mobile app
- B.
All features of the mobile app first, then the basic features of the web app
- C.
Basic features of the database, then basic features of the mobile app, followed by advanced features of the database and mobile app
- D.
Basic features of the mobile app, then basic features of the database, followed by advanced features of the mobile app and database
Correct Answer
D. Basic features of the mobile app, then basic features of the database, followed by advanced features of the mobile app and databaseExplanation
The best strategy for developing the product according to just-in-time manufacturing is to start by developing the basic features of the mobile app. This allows for a proof-of-concept mobile app to be made without the need for a database connection. Once the basic features of the mobile app are completed, the basic features of the database can be developed to establish the necessary connection. Finally, the advanced features of both the mobile app and the database can be built on top of the basic features. This approach ensures that the product can be released with essential functionality and additional features can be added incrementally.Rate this question:

You are developing a software product using Kanban. You have the following phases of development, which happen one after another in sequence: Design, implementation, acceptance testing, and delivery. The amount of work that can be completed in each phase per week is as follows: 5 units in design, 6 units in implementation, 3 units in acceptance testing, and 10 units in delivery. Each of these units is a consistent measure of the amount of work completed. For this example, one unit deals with one requirement. According to the amount of work that is done in each phase, in what phase is the bottleneck located?
- A.
Design
- B.
Implementation
- C.
Acceptance testing
- D.
Delivery
Correct Answer
C. Acceptance testingExplanation
The bottleneck is located in the acceptance testing phase because it has the lowest amount of work that can be completed per week compared to the other phases. This means that the acceptance testing phase will take longer to complete compared to the other phases, causing a delay in the overall development process.Rate this question:

Let’s see if you can pick out some examples. Of the following, which would you consider software requirements?
- A.
“As a hotel manager, I want to be able to check guests in”
- B.
“I am required to make you sign a contract”
- C.
“Account holders will enter their banking PIN into a numeric keypad”
- D.
“Users are male”
Correct Answer(s)
A. “As a hotel manager, I want to be able to check guests in”
C. “Account holders will enter their banking PIN into a numeric keypad”Explanation
The correct answer is "As a hotel manager, I want to be able to check guests in" and "Account holders will enter their banking PIN into a numeric keypad" because these statements describe specific functionalities or actions that the software should be able to perform. They represent user requirements or system requirements that need to be implemented in the software. On the other hand, "I am required to make you sign a contract" and "Users are male" are not software requirements as they do not relate to the functionality or behavior of the software system.Rate this question:

Suppose you are forming requirements for an invoicing product that needs to calculate sales tax. Which type of requirement are you creating?
- A.
Business requirement
- B.
Business rule
Correct Answer
B. Business ruleExplanation
The correct answer is "Business rule" because a business rule is a specific statement that defines or constrains some aspect of the business. In this case, the requirement for the invoicing product to calculate sales tax is a specific rule that needs to be implemented. It is not a general business requirement, which would describe the overall goals or objectives of the product.Rate this question:

Feel free to "Skip" if you have not yet taken the Software Processes and Agile Practices course. In which software development process model would requirements and design be two completely separate phases?
- A.
Sawtooth model
- B.
Spiral model
- C.
Unified Process model
- D.
V-Model
- E.
Waterfall model
Correct Answer
E. Waterfall modelExplanation
In the Waterfall model, requirements and design are two completely separate phases.

Hal developed a game to be played on a mobile device. The game involves users clicking colourful circles before they disappear. The music in the game would speed up when circles were about to disappear. The phone would vibrate when a circle was clicked. Hal was reading the feedback that he received about his game. Most of the feedback was positive, however, there were a couple complaints about usability. Which of the following complaints represent a physical limitation?
- A.
“I can’t see some of the circles, because the circle and background colours are too similar”
- B.
“I have limited hearing, and I feel like I’m at a disadvantage, because I can’t hear the music well”
- C.
“I hate that the phone vibrates when I press a bubble, it’s really annoying”
- D.
“I can only play the game for so long before my hand gets tired”
Correct Answer
D. “I can only play the game for so long before my hand gets tired”Explanation
The complaint "I can only play the game for so long before my hand gets tired" represents a physical limitation because it indicates that the person's hand becomes fatigued after playing the game for a certain period of time. This suggests that the physical act of clicking the circles on the mobile device is causing strain or discomfort in their hand, limiting their ability to continue playing the game.Rate this question:

You and your development team are creating an online shopping website, for a company that sells pet supplies online. The client is very specific about what they want. She wants a green background with red text. She wants pictures of animals that are animated to look like they’re dancing. And she wants all products displayed on the front page, sorted by price from high to low.Your development team is a little uneasy about this design. They try to convince her to let go of these features. One developer explains that it’s hard to read red text on a green background, and that people who are colorblind won’t be able to read it at all. Her favorite colors are red and green, so she was hesitant to change her mind, but eventually she agreed to a green background with blue text. Not ideal, but better. The development team then try to convince her out of sorting prices by high to low. They decided the dancing animals were harmless and the least of their worries. They explain to the client that the user should be able to sort by animal type, or product types, like food, toys, etc. They explained it would make the website much easier for users, and less crowded on the main page. She refuses to change the sorting system. What should be the next approach for the development team in this situation?
- A.
Create the website with all her requests, and deliver the product she wants.
- B.
Provide experimental data, to show her that sales can be increased with a better sorting system.
- C.
Make the animal dance moves inappropriate, just to spite her.
- D.
Create a website that is visually appealing and has a great sorting feature.
Correct Answer
B. Provide experimental data, to show her that sales can be increased with a better sorting system.Explanation
The next approach for the development team should be to provide experimental data, showing the client that sales can be increased with a better sorting system. This approach aims to convince the client by presenting evidence that a different sorting system would lead to improved user experience and ultimately higher sales. By providing concrete data, the development team can make a persuasive argument and potentially convince the client to reconsider her decision.Rate this question:
