Where I come from we have a turn of phrase: “That’s a load of cobblers”.
I’m sure you can work out what it means.

And using Agile as a holistic business management or project management methodology is a very large steaming pile of it.

The four values are little more than a thinly-veiled zero-sum game of ‘for me to win, you have to lose’.

It is based upon a belief system, not upon hard evidence. And you can not challenge a belief system. Therein lies the ‘Plato Truth Virus’ problem’.

I have a manifesto, and I believe I am Right.
We can not both be Right.
Therefore you must be Wrong.
And because you are Wrong, that supports my belief that I am Right.

The true game changer is not why you value one component over another. That is divisive, separatist and every bit as siloed as the organisational structure it purports to be trying to overcome.
The true game changer is:
Under what conditions can we have both?
How do our processes and tools ENABLE interactions between individuals?
How do you structure your documentation and specifications in a way that ENABLES working software?
How do you structure contractual negotiations in a way that ENABLES customer collaboration?
And suggesting that Responding to change is more important than following a plan strongly suggests that the writer has no concept of what a plan actually is.
The better question is What kind of planning process ENABLES being more responsive to change, and how to evolve your existing system to incorporate this?

These are all win-win outcomes.

None of them require a new ‘industry’ now called Agile Project Management.
They’re simply business problems that require solving with a ‘common goal, common problem, common solution mindset’.

The Twelve principles are nothing more than common sense. A entirely new ‘discipline’ from a so-called methodology that invents a new model of training, knowledge, certification and consultancy income streams is not at all necessary.

You can achieve the successful outcomes you seek with appropriate behavioural choices and practical application of common sense, by continually striving to seek win-win outcomes.

You don’t need a new method to be agile. You can behave agile anytime you like.

It’s a choice, not a method.
