Agile Software Development Week 01 Quiz Answers

Quiz 1: Agile Values and Principles

Q1. What are some of the challenges with waterfall methods that prompted the software industry to come up with alternatives like agile? Select three.

• It is difficult to predict user/customer needs
• Projects cost too much
• Incorrect interpretations of requirements by developers go undetected for a long time. During user acceptance tests, these issues are discovered but it is very late.
• Integration issues between different components of the software go undetected for a long time. During the testing phase, when all the components are integrated, these issues are discovered but it is very late in the process.
• Projects were very complex and big

Q2. What are the four values of the Agile Manifesto?

• Responding to Change Over Following a plan
• Customer Collaboration Over Contract Negotiation
• People and Interaction Over Processes and Tools
• Planning Properly Over Just Executing
• Working Software over comprehensive documentation

Q3. Which Agile Value does the following principle align with:

“Build projects around motivated individuals, give them the environment and support they need, and trust them to get the job done.”

• Individuals and Interaction Over Process and Tools
• Respond to Change Over Following a plan
• Customer collaboration over contract negotiation
• Working software over comprehensive documentation

Q4. Which of the following aligns with the agile principle:

“Business people and developers work together daily throughout the project.”

• Since agile methodologies do not recommend writing all detailed requirements upfront, it is really important to support greater collaboration between business people and developers so that they can build a shared understanding of what needs to be built.
• Business people and developers MUST meet face-to-face daily to clarify confusion, questions, etc.
• Business people also need to code together with developers to make faster progress.

Quiz 2: Using Agile Methods

Q1. What are some of the benefits organizations have seen from using agile methods? Select five.

• Project Visibility
• Increased productivity
• Increased project governance
• Increased Team Morale
• Improved Business / IT Alignment
• Better Software Quality

Q2. The agile principle of “Deliver working software frequently” helps with which of the following challenges of the predictive model? Select two.

• It helps prevent change
• It helps validate user needs.
• It helps detect translation issues.

Q3. What new challenges does agile bring? Select two.

• Very uncomfortable for leaders because of the unpredictable journey
• Architecture/Design/Database modeling is challenging
• Agile eliminates all documentation hence making it very difficult to use the software

Quiz 3: Applying an Agile Mindset

Q1. What are some of the tactics/concepts you can use to implement an agile mindset? Choose two.

• Create a lot of meetings to increase collaboration
• To keep the cost of change down, use engineering practices like automated tests, continuous integration, incremental design
• Build in small bite-sized chunks. These chunks could represent both iterative and incremental approaches
• Don’t waste too much time documenting, planning or designing. Focus your time on coding and implementation always.

Q2. If a developer says “We don’t do any discussion or upfront design” because we are agile”, is he/she truly representing what agile means

• Yes, because in Agile, we start coding right away
• No, agile does not mean starting coding right away.

Q3. When applying agile, we don’t need to do any release planning.. We only plan for a week.

• True
• False

Quiz 4: Agile Fundamentals

Q1. Which of the following statements align with the value of “Working software over comprehensive documentation” of the Agile manifesto?

• Value delivering software over writing documentation.
• An agile coach says to the team “Documentation is of no use.”
• A manager tells the team: “Writing certain documentation is company policy so we must create them irrespective of its use.
• If documentation is absolutely essential then create it.

Q2. Which of the following is true about the Agile Manifesto? (select any 2)

• Agile Manifesto was primarily based on theoretical knowledge
• The Agile Manifesto specifies the exact practices and processes that Agile teams are expected to follow
• The Agile Manifesto consists of 4 values and 12 principles.
• The Agile Manifesto is a work in progress and we are continuing to learn.

Q3. Which one of the following statements/situations/conversations align with an agile mindset?

• A manager providing a status update to a customer says: “We are done with requirements and design so we are 50% done.”
• A manager e-mails her team: “Meeting face to face just for a 15-minute discussion is inefficient, let us all just dial in from our desk.”
• A software vendor says to a client: “We must define exactly what the user needs and put that in the agreement.”
• Manager: “The customer is suggesting another change in feature X which is complete according to the specification. They agree that it was built as we agreed upon but it lacks some functionality and will result in user frustration. Should we implement the change or not?”
• Developer: “Yes, if it does not fulfill user needs, we should make the change.”

Q4. Why is it difficult to predict user needs and requirements? (select any 3)

• Difficult to understand user needs.
• Translation issues. Requirements are misinterpreted.
• Sometimes the market shifts from time when the requirements were originally defined.
• There is not enough time spent on requirements. If we spend more time early, we can define requirements very accurately.

Q5. Which of the following statements align with following Agile Principle:

• “Deliver working software frequently, from a couple of weeks to a couple of months, with a preference for the shorter timescale”
• We MUST release software to actual users every couple of weeks.
• We should frequently deliver software in some environment (not necessarily to production always) to gather user/client feedback
• We should NOT release software to a production environment on a shorter timeframe. We should ONLY release it in lower environment (e.g., a test environment).

Q6. Which of the following aligns with this principle:

” Working software is the primary measure of progress.”

• If a team has delivered 5 features out of 10 features (or stories), the team has made progress (they are more than 0% done)
• If a team has written the requirements and done the design for 5 out of 10 stories, then the team has made some progress (they are more than 0% done)
• On a 10-month project, the team has been working for 5 months. Thus, the project is 50% complete.

Q7. In which of the following situations, would you NOT recommend using an agile process?

• For a project where change is not expected. requirements are well-known, and the solution is both well-known and repeatable.
• For a project where the customer has an idea of what they want to build but is not sure of his/her exact needs.
• For a project where the customer wants to build an e-commerce website the development team has never done something like this before. Further, the company knows that they want to build an e-commerce website but are not sure about the functionality at this time.
• For a project where requirements are well known but the technology and solution are unknown (i.e., changes expected in the solution).

Q8. Which of the following is true for agile projects?

• An agile methodology may help a team to go to market early by delivering with limited functionality.
• Agile methods do not require rework because the team knows exactly what they building. No refactoring of code is needed.
• Scrum is the best way to implement agile.
• If somebody says, they use an agile methodology, they must be doing either Scrum or XP.

Q9. One of the core principles of agile is to “Embrace Change”. This makes architecting and designing the system challenging since you don’t know all of the requirements upfront. Thus, you have to be prepared to make architecture and design changes. To effectively embrace change, agile teams must learn how to keep the cost of change low.

• From the options below, select the ones that can help mitigate this challenge. (Select 3)
• Keep the design simple and just build what is required. It is easier to change a simple design than to update a complicated design.
• Automated Regression testing provides faster feedback which helps you detect defects quickly. This in turn, gives you confidence to make changes.
• Try to define as many requirements as you can at the beginning of the project, and spend a good amount of time designing the system.
• Keep the code clean and continuously improve/refactor the design as needed. Don’t delay these changes for later.

Q10. Which of the following is true for a typical agile project? (select 2)

• No discussion sessions happen around what we want to build. We start with coding.
• The team talks about the high-level software architecture/design as well as their approach for building software (the release plan) before directly jumping into coding.
• The team does a detailed design before starting to code.
• If required, the team may need to plan and conduct training, etc. for users before launching the system.
• Release planning is never required on an agile project. We only plan for a day or for a week at the most.

• The horizontal axis (moving from left to right) in a story map represents time.
• The vertical axis (moving from top to bottom) in a story map represents rough priority.
• One story map can only have one user. It is not recommended to have multiple users on the same story map.

Q8. Due to an unpredictable market event, the Product Owner (PO) asked the team to complete the next release in 6 weeks. Assuming the backlog in Table 2 is up to date and prioritized from highest to lowest, the Product Owner wants you to estimate what can be done in next 6 weeks.
