One of the greatest questions to consistently badger a developer is "what technology should I use?". Days of thought and analysis determines which option(s) (from an increasingly growing number) best suits the need, manages volume and demand, plans for long-term strategy, simplifies/reduces support, and gets approved by colleagues and management.
Those steps may even seem easy compared to real life. The decision's complexity can get compounded by how much buy-in is needed, and the current constraints of existing technology plus developer knowledge. For instance, investing in an unknown or newer solution means allocation for learning costs.
