A key influence on cycle time is the variability in the time it takes to develop a new
feature. One of the best ways to reduce variability is to:
A. Work with reasonable small and similarly-sized stories.
B. Cycle time variability is inevitable and cannot be reduced.
C. Grouping relates stories into themes and prioritizing based on theme desirability.
D. Decomposing stories into tasks and estimating tasks instead of estimating stories. -
ANS-A. Work with reasonable small and similarly-sized stories.
Explanation
A - A key influence on cycle time is the variability in the time it takes to develop a new
feature. One of the best ways to reduce variability is to work with reasonable small and
similarly-sized units of work. Working at the task level can further reduce the variability
but compromise the Agile principles. Agile approaches are focused at the feature or
story level. [Cohn, M., 2006. Agile Estimating and Planning. 1st ed. Massachusetts:
Pearson Education. Page 246] [Problem Detection and Resolution]
A task included in an iteration plan that is being undertaken specifically to gain
knowledge or answer a question is known as:
A. Workaround
B. Epic
C. Spike
D. Sprint - ANS-C. Spike
Explanation
C - A spike is a task included in an iteration plan that is being undertaken specifically to
gain knowledge or answer a question. [Cohn, M., 2006. Agile Estimating and Planning.
1st ed. Massachusetts: Pearson Education. Page 154] [Continuous Improvement]
Agile teams usually limit their estimation to the next few week because:
A. Planning for shorter time periods eliminates multi-tasking.
B. Planning for shorter time periods is more accurate.
C. Planning for shorter time periods is easier.
D. Planning for shorter time periods results in higher ROI. - ANS-B. Planning for shorter
time periods is more accurate.
Explanation
B - Planning for shorter time periods do not have any direct relationship with a project's
ROI or multi-tasking. Although planning for shorter time periods is easier, this is not the
, reason why Agile teams plan for the next few weeks at the most. Planning for shorter
time periods is more accurate because work for the next few weeks is more predictable.
There is evidence, that the smaller the chunk of work, the more likely people are to
deliver it. [Agile Practice Guide, 1st edition, Page 61] [Adaptive Planning]
How do Agile approaches produce a more valuable product without formal change
control procedures?
A. By relying on the Agile teams to deliver a higher quality product.
B. By establishing self-managed teams who are capable of making changes
themselves.
C. By delivering in increments and incorporating feedback into future work.
D. By relying on the Agile coach to ensure the product meets all quality standards. -
ANS-C. By delivering in increments and incorporating feedback into future work.
Explanation
C - With an Agile approach to estimating and planning, teams reduce uncertainty about
the product ultimately being built as product increments are shown to potential users
and other stakeholders at the end of each iteration. Their feedback and responses are
used to fine-tune future plans. [Cohn, M., 2006. Agile Estimating and Planning. 1st ed.
Massachusetts: Pearson Education. Page 247] [Value-driven Delivery]
If $250,000 is invested at 8% with annual compounding. How much will this money be
worth in 15 years?
A. 78810
B. 1000000
C. 793042
D. 550000 - ANS-C. 793042
Explanation
C - You need to calculate the Future Value of 250,000 at 8% for 15 years. The formula
for Future Value is FV = PV * (1+r)^n. So to calculate, FV = 250,000 * (1 + 0.08)^15 =
$793,042. [Cohn, M., 2006. Agile Estimating and Planning. 1st ed. Massachusetts:
Pearson Education. Page 100] [Value-driven Delivery]
In Agile settings, what is the ideal frequency for conducting product demonstrations?
A. The ideal frequency for conducting product demonstrations is three weeks.
B. The ideal frequency for conducting product demonstrations is two weeks.
C. The ideal frequency for conducting product demonstrations is one week.
D. There is no ideal frequency, but rather a general guideline of conducting
demonstrations at least once every two weeks. - ANS-D. There is no ideal frequency,
but rather a general guideline of conducting demonstrations at least once every two
weeks.
