Don't be a slave to the backlog.
I’ve been spending a lot of time helping one client with their 2011 Product Roadmap. Although we’re not “doing Agile,” I’ve introduced them to the product backlog. So far it’s been a powerful planning tool. So Scott Sehlhorst’s post on how to prioritize resonated with me.
When creating a backlog, or managing features, you need to remember that feature priority is a tool to be used to plan your work. Don’t get too specific about the exact rank of individual items, and remember that the eventual order of implementation should reflect what from a business, technical, and user perspective. It’s a compromise. The backlog is the beginning of knowledge, not the end.
