Question 1 of 20
1. Question
How often do releases happen?
Correct
Releases are fortnightly which is why there are jumps on the chart. This isn’t good for flow and is, in effect, holding inventory. You’ve done the work, so why not get it ‘out there’ and delivering value to the business?

Question 17 of 20
17. Question
Using the data on the above histogram, if you were asked for a 100% guarantee of how long a new task would take, which of the following would most likely be the basis of your response?
Correct
We don’t give 100% guarantees because it is impossible for us to do so; the best you can say is that, using past data, 95% of that work took 13 days or less – of course it might take longer, but it might also take a lot less. That is the most reserved of the 3 confidence figures on the histogram.
