Are you using one in your team? How exactly?
It's a pity I was shown this several months after I'd been let go for "poor fit".
I've always wondered what happened to the poor guy who had been assumed to have my skill set and had to live up to it. Probably got canned later for "not delivering to expectations".
I'm sure these are a good tool in the right hands, much like chainsaws. But I still have suspicions on how they are used.
Indeed, it can easily lead to disasters if not used correctly (wrong inputs, outdated, etc..). We're currently using one for our team (~5 people) but I'm looking into how it can scale up to the whole engineering organization (~100 people).
Its a tool. Like a chainsaw. You can use it to make ice sculptures or to hack off an arm. Metaphorically.
