Mistaking making for the thing you've made

Jason Fried:

The speed at which a product is developed doesn't inherently make the product better or worse. The number of commits doesn't make the product better or worse. The number of people or agents working on it doesn't make it better or worse. The number of hours you’re pouring into it doesn’t make it better or worse. Working on a weekend, or late into the evening, doesn’t make it better or worse [...]

Those are all development metrics and styles of work [...] Important to those making the work, but not inherently important to the people using the work.

[...] It's like reviewing a restaurant by talking about how many cooks were in the kitchen, how long the shift lasted, how many orders they fired, or how late they stayed cleaning up. None of that tells you about the meal, the product, the customer’s experience.

Measurements around a thing are merely proxies for the thing itself. They do not equate.
