Section 7 Principles detail

Question 1 of 24

1. Question

In the early stages of a project what is the effect of providing a precise estimate, based on major assumptions and limited detail?

It gives an illusion of certainty
It gives the customer confidence
It allows the project manager to manage the risk
It allows for detailed story decomposition

Question 2 of 24

2. Question

Why is it important to make business risk visible?

It allows the customer to make business decisions based on a realistic assessment of uncertainties
It ensures all responsibility for successful delivery sits with the business
It shows the estimator has put a lot of thought into the estimate
It makes it more likely that the work will go ahead

Question 3 of 24

3. Question

Which of these is NOT defined as a way to validate an estimate?

Using a facilitator
Collaboration
Using more than one estimating technique
Learning from experience

Question 4 of 24

4. Question

Who makes the decision about the acceptable level of business risk for a project?

The business
The project manager
The sponsor
The finance department

Question 5 of 24

5. Question

What is a benefit of team-based estimating?

It ensures a broad validation of understanding and assumptions
It ensures the problems that testers always encounter are documented
It ensures the project manager gets an estimate they are happy with
It ensures individuals avoid blame later

Question 6 of 24

6. Question

What is the value of checking estimates regularly on an agile project?

There is growing evidence to inform later work
There is growing evidence how hard the team members are working
There is growing evidence to prove which individuals are letting the team down
It highlights the difference between the good estimators and the bad estimators

Question 7 of 24

7. Question

What is a stated benefit for estimating when using an agile incremental approach?

It allows assumptions to be validated or disproved
It allows the users to understand how hard the team are working
It avoids the need for assumptions
It ensures accuracy and precision from the start

Question 8 of 24

8. Question

On an agile project when does evidence about the estimate start building?

From the first sprint
From the first progress report
From the first retrospective
From the first sprint planning session

Question 9 of 24

9. Question

How does an estimator deal with uncertainty?

By using assumptions to progress despite unknowns, and by including risk and contingency
By creating an algorithm to increase the base estimate
By doing more investigation up front
By ensuring the final estimate is doubled

Question 10 of 24

10. Question

What is a known benefit of using agile?

Agile has the ability to deal with uncertainty in a fast-changing work
Agile guarantees delivery of a 100% solution, even when uncertainty is high
Agile is about being flexible, so extending the deadline is a useful option if problems appear
Agile puts the team in charge so they can plan in enough time to build brilliant solutions

Question 11 of 24

11. Question

For agile estimating, which statement is true?

Contingency always needs to be factored in to allow for uncertainty
Contingency is a necessary evil in an uncertain world
Contingency should be added on by the estimator, after discussion with the project manager and the business sponsor
Adding contingency to an estimate removes the need for holding a risk log

Question 12 of 24

12. Question

How does agile typically build in contingency?

With the expectation that lower-level requirements may be dropped
With the expectation that delivery may be delayed
With the expectation that overtime is always an option
With the expectation that additional team members may be brought in

Question 13 of 24

13. Question

Which statement does NOT relate to Know the Purpose?

Spend the least amount of money
Know what the estimate will be used for
Use the appropriate level of detail
Spend the right amount of time

Question 14 of 24

14. Question

How does risk-based estimating work?

By allocating an impact value on key risks and adding this to the base estimate
By allocating 10-20% to the base estimate to cover risk
By allocating a pool of additional people who could be brought in if risks become issues
By holding more detail in the risk log

Question 15 of 24

15. Question

Which of these is a common use for an estimate?

To establish a basis for an action or a decision
To ensure the team will be working at full capacity
To justify a pay rise
To ensure good performance is reflected in annual appraisals

Question 16 of 24

16. Question

What is an advantage of risk-based estimating?

The allocated contingency can be released when the risk goes away
There is always contingency if something completely unexpected happens
If the risk does not happen, then the funds can be used for the end of project celebration
The allocated contingency is always available to be swapped to a different risk

Question 17 of 24

17. Question

What are investment decisions typically based on?

Understanding how to allocate finite funding to get the best return on investment
Being able to cut the estimate to the lowest possible figure
Seeing how to allocate funding fairly across different business areas of the business
Being aware of the current share value of the organisation

Question 18 of 24

18. Question

Who owns the business risk?

It always sits with the business
It always sits with the team
It always sits with the project manager
It always sits with the Scrum Master

Question 19 of 24

19. Question

What is needed to build effective customer and supplier engagement, from an estimate as part of a tender?

Provision of a level of certainty that allows contractual engagement
Plenty of contingency to ensure the supplier avoids all risk
A range of numbers
The lowest possible level of decomposition

Question 20 of 24

20. Question

Why is it preferable that those doing the work create the estimate?

To ensure buy-in to the estimate
So they can add in enough contingency to ensure they will not be overworked
To ensure that management can see who got it wrong, if there are problems
Working this way is more fun

Question 21 of 24

21. Question

When work is in flight, which of these is NOT a recommended use for an estimate?

To apportion blame fairly
To compare progress to plan
To confirm or reset expectations
To adjust plans as necessary

22. Question

Which of these is a valid reason for the team delivering the work not creating the estimate?

If the team have not yet been assigned to the work (in the early stages)
If some team members work part-time (during sprints)
If some team members have not been trained to estimate
If the project manager has a better understanding of what needs to be done

Question 24 of 24

24. Question

It encourages discussions and validation of assumptions and estimates
It is a good team-building exercise
