Strict or pragmatic Scrum? Do you practice Scrum strictly after its rules or are you going a more pragmatic way, picking out the bits that suit you/your environment best, maybe mixing it up with other methodologies ? In other words, do you bend Scrum to suit your environment or do you change your environment to suit Scrum ? Which way you think is the better ?

Scrum and Agile are loosely-defined. Every company implements it differently depending on how much they can "tolerate." I've worked on projects where we don't use sprints, and other projects where we break down stories to hourly items.

The best way to implement it is to use whatever practices benefit you, and leave whatever doesn't. While some "puritans" may complain that it's not scrum, reality dictates that unless people get benefit out of it (or see benefit in the process parts of it) they won't want to implement it.
