scrum : Information Radiators or Tools in Scrum Projects


One of the main advantages of Scrum is that the whole activity is transparent for all and the information can be viewed directly from information tools such as Scrumboard, where the progress of the team can be made visible. The progress of a team can be planned accurately and tracked by the Scrumboard during each Interval of a Sprint. The Scrumboard consists of four columns for indicating the progress of the proposed tasks in a Sprint; the first one consists of the “To Do” column, i.e., for tasks in the pipeline, the second column consists of a “To Do” column for tasks that have not yet started, the third one for “In Progress” column for the tasks that are in action but not concluded and the final column stands for tasks which have been completed including the successful completing of tests. It has to be noted that in the initial stages of a Sprint, all the tasks for that phase are confined to the “To Do” column and their place changes as the project proceeds to completion.
The Scrum board is usually maintained on a white board or on paper, or as in recent times, where it is managed electronically on a Spreadsheet. Changes in the Scrumboard should be managed by the Scrum team as per the standards of time so that the information is transparent for the stakeholder and other team members to ensure that the project is on the right track as per the guidelines.
Another important tool in this regard is Impediment Log in which all the impediments affecting the project are documented. An Impediment is usually described as an obstacle, hindrance or hurdle which can decrease the productivity and performance of the Scrum team. It is mandatory that they should be identified as soon as possible, solution found in quick time and they should be removed in order for the team to contribute effectively. They can be classified into two types: Internal and External. Internal Impediments can be classified as either improper communication or reduction in performance of workforce whereas External impediments could involve various factors such as requirement of unnecessary documents or issues in software license. An organization can suffer from unwanted cost if it fails in identification or not finding an appropriate solution in dealing with this factor. The Scrum Master is responsible for recording the impediments in the Impediment Log and these issues can be discussed and sorted in Daily Standup Meetings and Sprint Review Meetings.
Sprint Burndown Chart is another key information radiator in Scrum. The Sprint Burndown Chart is a graph that depicts the amount of work remaining in the ongoing Sprint. The initial Sprint Burndown Chart is accompanied by a planned burndown. The Sprint Burndown Chart should be updated at the end of each day as work is completed. This chart shows the progress that has been made by the Scrum Team and also allows for the detection of estimates that may have been incorrect. If the Sprint Burndown Chart shows that the Scrum Team is not on track to finish the tasks in the Sprint on time, the Scrum Master should identify any obstacles or impediments to successful completion and try to remove them. A related chart is a Sprint Burnup Chart. Unlike the Sprint Burndown Chart which shows the amount of work remaining, the Sprint Burnup Chart depicts the work completed as part of the Sprint.
