What is the relationship between technical debt and transparency?
(choose the best two answers)
Choose ALL answers that apply.

It increases transparency as technical debt must be cleared before the Developers can work on functional development.
As development progresses and code is added, the system becomes more difficult to stabilize, which results in making future work more difficult to complete.
Estimating technical debt helps the Product Owner know when an Increment will be released.
It leads to false assumptions about the current state of the system and the state of the Increment that is delivered.

True or False: Product documentation can be a requirement as a part of an Increment.
Choose only ONE best answer.

TRUE
FALSE
