Q:

On an uncertainty space diagram, if you have low means uncertainty, what does that indicate?

Q:

On an uncertainty space diagram, what does the navigation path depict?

Q:

On an uncertainty space diagram, from high means and high ends uncertainty, a waterfall process would tend to navigate toward which way initially?

Q:

For a software product, what is an effective initial basis to form a work breakdown structure for its implementation?

Q:

What would be a useful way to determine the specific project risks for a software product?

Q:

A software product team is applying Scrum, and is breaking down the work for a user story into required developer tasks. They have identified an implementation task to write the source code. To meet a typical definition of “done” for this user story, which other tasks should be identified?

Q:

A software team is breaking down the work for a user story into required developer tasks. They have identified a task to add a section to the user manual for the feature. They also have a task to spellcheck the new section. Would this be appropriate?

Q:

A development team thinks that it should take them four months to complete everything that the client has asked for. The client wants it delivered in two months, on New Years Day. The development team and client determine that they will complete half of the requested requirements. Which of these is the commitment?

Q:

What are story points?

Q:

What are the consequences of having an inflated story point estimate for a user story?

Q:

How do you calculate the actual velocity of a team for a sprint?

Q:

A development team calculates their velocity to be 20 story points in their recently finished sprint. They had completed a user story estimated at 5 story points. However, later in the project, it is noticed that the user story needs some enhancements, estimated at 1 story point. How should their previously calculated velocity be revised?

Q:

In release planning, what user stories should be planned first for development in the earliest sprints?

Q:

Suppose, while release planning, the total number of story points of user stories chosen for the next sprint exceeds the development team’s estimated velocity. What should be done?

Q:

In release planning, a development team estimates their velocity to be 20 story points. For the next sprint, they plan to finish 2 high priority user stories of 5 story points each. With 10 story points left, which of the following combinations of user stories should they choose (assuming the stories are independent and equal risk)?

Q:

Suppose a release plan has a user story to be completed in the current sprint. At the end of the sprint, however, the tasks for the user story have not started. How should the release plan be updated?

Q:

What does the cone of uncertainty mainly illustrate about estimates?

Q:

A team of 3 developers is estimating the time to complete a user story. One developer forms an estimate by determining the tasks needed, estimating their times, and deriving a total. Another developer implemented a similar user story for another product, and derives an estimate based on personal experience. The third developer looked at another user story with the same number of story points and used its time estimate. How should they come to a final estimate?

Q:

In estimating the duration to complete a project, the resulting interval that would contain the actual duration about 68% of the time is 14 to 24 days. What is the interval that would contain the actual duration about 95% of the time?

Q:

For a software requirement, a development team is planning a task to write the implementation code and a task to inspect a reviewable version of the code for defects. After the inspection, the coding task addresses the discovered defects for the final version. What kind of task dependency is this between the coding and inspection tasks?

Q:

A product support team has a long-term task to operate version 1 of an invoicing service. Version 2 is almost ready for to replace version 1, so another long-term task is planned to operate that version. The service must be available at all times, so if version 2 is not in place, version 1 is used. What kind of task dependency is this between the version 1 and version 2 operations tasks.

Q:

In a PERT chart, the nodes represented milestones. When multiple tasks lead directly into a node, what does that mean? Choose 2 responses.

Q:

Suppose for the tasks of an iteration plan, the critical path from begin to end to implement the user stories for the sprint has a total duration of 80 hours. There is an independent path from begin to end to prepare training materials for a separate set of features, and there is 16 hours of slack on that path. How much time is planned to prepare these training materials?

Q:

Suppose while iteration planning, the total story points for the user stories of the sprint is below the estimated velocity, but the total estimated task hours for the tasks of these stories is above the available time for the team members. What should be done?

Q:

Within a sprint, for a user story, one developer finished their tasks earlier than expected, allowing some spare time. What should the developer do with the spare time?

Q:

At a development meeting to decide the underlying technology for a software product, one of the developers used their expert knowledge about one technology to pressure the rest to use it. The other developers are not convinced, but to avoid conflict, decide to follow using this technology. Which anti-patterns are happening here?

Q:

The development team is deciding between two platforms for a software application. One involved proprietary tools around a proprietary language, and the contract would create a long-term relationship that would allow a relative of the team lead to profit. The other platform is open, with alternative tools. Which anti-pattern results from choosing the first platform?

Q:

A development team decides to tune an existing algorithm for more speed rather than implement a better algorithm. One developer disagrees with the decision and works on the new algorithm without telling anyone. The new algorithm is taking a lot of effort, which results in not finishing other tasks, and planned user stories are not being completed for the sprint. What could the team have done to avoid this? Choose the two that are correct.

Q:

For risk planning, an impact versus likelihood matrix combines a ___ and ___ to derive a single value of its ___, reducing 9 combinations into 3 categories to consider.

Q:

For a project, the developers will follow Agile practices and the Scrum methodology. The impact of running out of funding for further development is relatively ___.

Q:

Suppose a Scrum development team for a software product is located across two sites, 3 time zones apart. In a risk plan, there is a risk identified and indicated of poor remote communication. What would be suitable actions for this risk? Choose the two that are correct.

Q:

An experienced Agile team is forming a release plan, and there are two user stories, both with high value. However, one user story is low risk and one is high risk. Which should be done first and why?
