Scrum isn't for everybody. I would say it is for organisations or departments whose business is not developing products, but who develop products to service their business needs. For everyone else, there are many better options to choose from.

That said, lets clear up some misinformation:

1) Scrum is vague? It said it right there: "Scrum is a framework" - Scrum is NOT a process, technique, or definitive method.

2) On delivery windows - "I’m not against management being informed… but at what cost?". Scrum works well for businesses/departments that have a development need, not where the business IS development. It needs to fit into the business, not vice versa, and that means managing stakeholder expectations.

3) On scrum managers - "let the lead developers handle the job." Of course! Or your development team manager, depending on your org setup. The roles in scrum are ROLES - not a new org structure.

4) Estimates - sure, points are stupid. They literally make no sense. They aren't prescribed by scrum in any way, shape, or form. There is nothing wrong with using time as an estimate. Period.

I think the target audience of Scrum could be made a LOT more clear. It would save a lot of heartache and hate. I think successful marketing and certification have become the chief enemy of Scrum - orgs have tried to shoehorn it in everywhere, and thats not what it is for.
