So your team has decided to hold a Release Planning Meeting to better align iterations with the bigger picture and ensure that you can actually deliver a full release of your software. Congratulations! This is an important step. By getting the whole team involved in a single meeting, you can:
– See the whole
– Discover whether your release date and desired features are in alignment
– Identify key dependencies
– Plan for involvement of external groups
– Develop a sense of excitement and being "part of something bigger" for individual team members.
