Your team is currently using Azure DevOps for applications being developed in the company. You want a metric to assess the amount of wasted time due to the technical debt in the application code. Which of the following could be used for this purpose?

Answer options:

A.The number of code modules in the application
B.The number of unit test failures
C.The percentage of unit test failures
D.The percentage of overall time spent on rework

Answer – D 
If the application code has technical debt, this means that the team is spending time on existing issues. The technical debt would make it difficult to deliver changes faster efficiently. 
The other options are incorrect because none of them would provide the option of a metric showcasing the lost time because of the technical debt.
