A) Burn up charts separate out the rate of progress from the scope fluctuations B) Burn up charts and burn down charts trend in opposite vertical directions C) Burn up charts can be converted to cumulative flow diagrams by the addition of WIP D) Burn down charts indicate whether rate of effort changes are due to changes in progress rates or scope 8) As part of stakeholder management and understanding, the team may undertake customer persona modeling.

To best describe how much money you hope the project will return, you should show an estimate of: A) Internal rate of return (IRR) B) Return on investment (ROI) C) Gross domestic product (GDP) D) Net present value (NPV) C) We improve and elaborate our agile process with each increment delivered.

A) Welcome changing requirements, early in development. Agile processes handle changes for the customer's competitive advantage. B) Welcome changing priorities, early in development. Agile processes harness change for the customer's competitive advantage. C) Welcome changing priorities, even late in development. Agile processes handle changes for the customer's competitive advantage. D) Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage. Answer: D Explanation: The correct wording of the principle is “Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.” The agile principles do not speak to changing priorities or to welcoming only early changes. 2) When managing an agile software team, engaging the business in prioritizing the backlog is an example of: A) Technical risk reduction B) Incorporating stakeholder values C) Vendor management D) Stakeholder story mapping Answer: B Explanation: We engage the business in prioritizing the backlog to better understand and incorporate stakeholder values. Although such engagement will likely impact technical risk reduction, vendor management, or stakeholder story mapping, these are not the main reasons we engage the business. 3) Which of the following items is not a benefit associated with product demonstrations? A) Learn about feature suitability B) Learn about feature usability C) Learn about feature estimates D) Learn about new requirements Answer: C Explanation: Product demonstrations provide the benefits of learning about feature suitability and usability, and they can prompt discussions of new requirements. They are not typically used to learn about feature estimates, however, since estimating is done during estimation sessions, rather than during demonstrations. 4) Choose the correct combination of XP practice names from the following options: A) Test-driven design, refactoring, pair programming B) Test-driven development, reforecasting, peer programming C) Test-driven development, refactoring, pair programming D) Test-driven design, refactoring, peer programming Answer: C Explanation: The XP practices include test-driven development, refactoring, and pair programming. “Test-driven design,” “reforecasting,” and “peer programming” are not XP practice names. 5) An agile team is planning the tools they will use for the project. They are debating how they should show what work is in progress. Of the following options, which tool are they most likely to select? A) User story backlog B) Product roadmap C) Task board D) Work breakdown structure Answer: C Explanation: Of the options presented, the best tool to show work in progress is a task board. The user story backlog shows what work is still remaining to be done on the project. The product roadmap shows when work is planned to be completed. Work breakdown structures are not commonly used on agile projects. 6) When using a Kanban board to manage work in progress, which of the following best summarizes the philosophy behind the approach? 11) What do risk burn down graphs show? A) The impacts of project risks on the project schedule B) The impacts of project risks on the project budget C) The cumulative risk severities over time D) The cumulative risk probabilities over time Answer: C Explanation: Risk burn down graphs do not show the impacts of the risks on the schedule or budget, but they do show the cumulative risk severities over time. Tracking just the probabilities over time would be of little use without knowing the impacts of these risks. After all, they could all be trivial, and in that case, why would we need to be concerned? 12) What is the process cycle efficiency of a 2-hour meeting if it took you 2 minutes to schedule the meeting in the online calendar tool and 8 minutes to write the agenda and e-mail it to participants? A) 90% B) 8% C) 92% D) 96% Answer: C Explanation: The formula for finding process cycle efficiency is: Total value-added time / total cycle time. In this question, the value-added time is 2 hours, and the total cycle time is 2 minutes + 8 minutes + 120 minutes = 130 minutes. So the correct answer is 120 / 130 = 92%. 13) The steps involved in value stream analysis include: A) Create a value stream map to document delays and wasted time, such as meetings and coffee breaks. B) Create a value stream map of the current process, identifying steps, queues, delays, and information flows. C) Review the value stream map of the current process and compare it to the goals set forth in the project charter. D) Review how to adjust the value stream charter to be more flexible. Answer: B Explanation: The only option here that is a step in value stream analysis is “Create a value stream map of the current process, identifying steps, queues, delays, and information flows.” None of the other options are valid steps in value stream mapping. 14) When we practice active listening, what are the levels through which our listening skills progress? A) 1) Global listening, 2) Focused listening, 3) Intuitive listening B) 1) Interested listening, 2) Focused listening, 3) Global listening C) 1) Self-centered listening, 2) Focused listening, 3) Intuitive listening D) 1) Internal listening, 2) Focused listening, 3) Global listening Answer: D Explanation: The progression is internal listening (how will this affect me?) to focused listening (what are they really trying to say?) and then finally to global listening (what other clues do I notice to help me understand what they are saying?). 15) The Agile Manifesto value “customer collaboration over contract negotiation” means that: A) Agile approaches encourage you not to focus too much on negotiating contracts, since most vendors are just out for themselves anyway. B) Agile approaches focus on what we are trying to build with our vendors, rather than debating the details of contract terms. C) Agile approaches prefer not to use contracts, unless absolutely necessary, because they hamper our ability to respond to change requests. D) Agile approaches recommend that you only collaborate with vendors who are using agile processes themselves. Answer: B Explanation: Valuing customer collaboration over contract negotiation means we look for mutual understanding and agreement, rather than spend our time debating the fine details of the agreement. 16) To ensure the success of our project, in what order should we execute the work, taking into account the necessary dependencies and risk mitigation tasks? A) The order specified by the project management office (PMO) B) The order specified by the business representatives C) The order specified by the project team D) The order specified by the project architect Answer: B Explanation: It is largely the business representatives who outline the priority of the functional requirements on the project. That prioritization is then a key driver for the order in which we execute the work. 17) Incremental delivery means that: A) We deliver nonfunctional increments in the iteration retrospectives. B) We release working software only after testing each increment. C) We improve and elaborate our agile process with each increment delivered. D) We deploy functional increments over the course of the project. Answer: D Explanation: Incremental delivery means that we deploy functional increments over the course of the project. It does not relate to retrospectives, testing, or changes to the process, so the other options are incorrect, or “less correct”. 18) In agile approaches, negotiation is viewed as: A) A zero-sum game B) A winner-takes-all challenge C) A failproof win-win scenario D) A healthy process of give and take Answer: D Explanation: In agile approaches, negotiation is viewed as a healthy process of give and take rather than a zero-sum game, a competitive challenge, or a failproof win-win scenario. 19) In Scrum, the definition of “done” is created by everyone EXCEPT: A) Development team B) Product owner C) ScrumMaster D) Process owner
