C) Trust that they will solve the bottleneck in the next batch or iteration

Question 7

In what way does DevOps take operational requirements into account?

A) By considering the workflow from start to end

Question 8

What helps a DevOps team to successfully develop and deliver working software?

B) COTS will save the business time and money, by reducing development time
C) Depending on the type of COTS used, the possibility of customization is limited

Question 13

There are many reasons for an organization to become interested in DevOps. When should an organization become interested in DevOps?

B) When continuous delivery is achieved and every change automatically results in a new version of the product
C) When continuous deployment is achieved and every change is immediately released to the customer
D) When continuous integration is achieved and every update to the code is saved immediately to Production
E) When the core business of the organization highly depends on information technology

Question 14

When value stream mapping, which metric is essential to measure for each step?

A) Cost of delay
B) Delay divided by duration
C) Key group comparison
