As others have noted, the amount of process involved with "Agile" these days is not in the spirit of the original Agile Manifesto. Additionally, how is it that _some_ organizations do it well, vs. others that make life hell?
This fundamentally comes down to how much the organization values and trusts its engineers. You only implement process if you cannot trust a person or group of people to do something on their own. You only track and measure performance by metrics if you do not trust them to work hard. This is easy to verify - how often is senior management beholden to process & measurement? Usually, the only "process" they need to go through is related to laws and regulations, which - again - is fundamentally based on how must we trust one another.
