Have you ever encountered a situation where your company defines certain authorized software and you need to change what you've been using for so long that it's an essential part of your tool set? Or when you need to migrate your process to use a new software and once you complete the migration you need to start a new migration for a different software?
I just can't understand the need for keep changing things just to get the new shiny object/buzzword.

Could go either way, but often this is because there's a great salesperson somewhere.
I get torn on this. sometimes having everyone work with the same toolset is good. Sometimes it's disruptive and slows things down. Ultimately, there should be rationale and it should make cost sense.
