In "Introduction to Disciplined Agile Delivery" why was it wrong for Dick the Database Administrator to secretly work on detailed logical and physical data models in his spare time?

1. Dick did not have the technical skill or experience to do the job well

2. Dick wasted time maintaining a detailed model while functionality was still evolving

3. This wasn't Dick's assigned responsibility and someone else was already working on it

4. Dick did not get approval from the product owner before working on the models

5. Dick should have used enterprise assets already available
