Don't Estimate Stories In Sprint Planning

I don’t estimate stories in sprint planning. Nor do I re-estimate stories in sprint planning. I estimate stories in a separate estimating meeting and usually at least a couple sprints in advance, if not more. There are a few reasons why (re)estimating during sprint planning is a dangerous practice:

Agile outside of software

While not every Agile practice can be taken out of software development and used someplace else the roots of Agile mean that the principles, values and ideas which Agile is built on can be. In your domain Agile as now known might work quite well, but in someone else’s domain there may be more need to think deeper.

On building teams: experience or talent?

Obviously when you hire, you want to find a good mix of experience and talent. But a perfectly balanced straddle between the two is impossible. So when forced to choose between them, which do you choose: experience or talent?

Morphia is an ODM library for MongoDB. It may be considered as the lightweight alternative of Spring Data MongoDB or as a richer version of Jongo. The Morphia core JAR is OSGi-ready.

Nearly All CMS Technologies Suck

They don’t use source-control as their backing store, and can’t possibly allow round-trip editing of content. As such technical perfectionists have been divorced and the TCO has gone ridiculously high because of lock-in, Conway’s Law, and concerted efforts to price their apps as cure-alls. I’m not interested in CMS applications, platforms, frameworks, or libraries that use a relational schema for storage of canonical content.
