“Push and Pull Messaging …” by Sean McGrath is a decision document between push and pull in a service delivery bus designed for the Irish government. Although the application is specific to that system, it also contains a great summary of the rationales one should use when choosing between push and pull. It fell off the web, but the Irish government very helpfully dug it out and gave me permission to re-distribute it.

I’d recommend it particularly to anyone thinking “Should I use SWORD for this system?”.
