We all know about the use of burn down and burn up charts as part of tracking sprints and release level commitments. One of the issues that most organizations face while they implement agile / scrum is to get the team to update data on a daily basis (in terms of effort remaining for tasks). This is needed for effective tracking of how the team is doing with respect to the original plan and whether commitments made are likely to be met by the end of the sprint. Team members do give an update as part of the daily stand up in terms of whether they are on track or not with respect to the tasks / stories they own (based on their own gut feel) but for some reason do not feel the need to update effort data on the tool used for tracking. Delivery management gets impatient and starts asking questions to the scrum master on where the team is during a sprint and why the burndown is not updated. This is not an issue with just a few teams but prevalent across the organization. Invariably this behavior leads to ineffective tracking and teams missing commitments on a regular basis. There is obviously a major issue of lack of predictability of delivery as a result of this.
You are hired as an Agile coach and one of your high priority focus areas is to help the Scrum Masters in addressing this issue. How would you go about doing this?
