I have a below question and wanted to discuss on possible right answer.
While under development the environment in which a product will be changed. What is the effect on the product backlog? • It is archived and a new product backlog is created to take its place • There is no effect, because it has to stay the same until the end of the project. • It evolves to reflect what the product needs to be most valuable • It is converted into a requirements specification to ensure stability
I feel both are right, It evolves to reflect what the product needs to be most valuable It is converted into a requirements specification to ensure stability
The right answer ist "It evolves...". Your other preferred answer is wrong because a requirements specification cannot ensure stability, especially not if the environment changes: If the environment changes, so do the requirements. If the requirements change, the product backlog changes and with it any requirements specification. As a product usually exists in a complex environment, it will never be possible to "ensure stability". That's why two of the pillars of empirical process control theory are inspection and adaptation: you have to accept instability and you cope with it by inspection and adaptation.
