To announce a new product launch date

2.
What does deployment frequency measure?
How many bugs are found in testing
How many developers work on each project
How long a team spends writing code

The number of failed deployments in a month
The time from code commit to production
The speed of code review approval
The time needed to fix bugs after release
Explanation:
Michael says lead time for changes measures the time from code commit to production.
4.
What can be inferred about a team that has high deployment frequency and a low change failure rate?
It probably has more production bugs
It is likely releasing fewer updates
It is not tracking any metrics
Its development velocity is likely faster
Explanation:
Michael states that higher deployment frequency and lower failure rate speed up development, so such a team is likely working faster.
5.
Why does Linda say, ‘That helps us see delays, right?’
She is confirming her understanding of lead time for changes
She wants Michael to define deployment frequency again
She is changing the topic to customer complaints
She is asking Michael to stop the presentation
Explanation:
Linda says this right after Michael explains that lead time for changes measures time from code commit to production, so she is confirming that this metric helps reveal delays.
