Venkat is the Scrum Master of ScrumGods, a team which has consistently been praised by all as a very Agile team. They did all their ceremonies without fail and team members collaborate well and their artefacts are all highly visible and so on. After a few months, some of the team members were getting a bit bored about doing the same and approached Venkat and asked him what they can do to move to the next level of Agility. They desperately wanted to improve and move up the ladder and started bugging Venkat to find ways by which they can bring in some advanced practices. One of the areas was their Velocity which, though consistent, was not improving much. Venkat thought that could be an area where something needs to be done and started thinking about it. Can you help Venkat to identify some advanced practice which can improve their Velocity?
