(second week) Burndown chart

Burndown Chart: A visual representation of the work that needs to be done before the project is completed. The Burndown chart has an x-axis representing time and a y-axis representing the work. Ideally, the chart is a downward curve, and as the rest of the work is done, "burn" to 0. Burndown charts are a common view that provides work progress. This word is often used for agile programming.

Related information: Kane mar the burndown chart is divided into the following seven cases: 1, Fakey-fakey: The surface is perfect. Software projects are so complex that it is difficult to define visual targets. In most cases, this figure comes from an environment full of command and control, in which open communication becomes difficult. 2, Late-learner: The Burndown chart will have a peak. Often appear in teams that communicate efficiently and are learning scrum. 3, Middle-learner: more mature than Late-learner. The team explored most of the tasks and complexities in the middle of the sprint. 4, Early-learner: Start with a peak, then a flat recession. The team recognizes the importance of early exploration and then works efficiently to achieve its goals. 5. Plateau: The team made great progress at the beginning, but lost direction in the latter part of the sprint. 6, Never-never: Burndown chart suddenly began to rise in the late sprint and will not fall again. These late changes need to be found as soon as possible and introspective. 7, the workload of scope-increase:sprint suddenly increased. This usually indicates that the team did not fully recognize the scope of the work at the Sprint planning meeting. Concrete Example Analysis:

Using the Burndown chart (Sprint Burn-down chart) to monitor and analyze the progress of the iteration, each Burndown chart is automatically drawn from Excel based on the daily update data of the sprint backlog.

1. Burndown Chart Horizontal: Duration 2, burndown chart ordinate: The total commitment work of the task in sprint. 3, Planning curve: Assume the member work productivity constant situation of the progress curve. 4, the actual curve: the actual progress curve.

Analysis:

1. Team members at the beginning of the task of the decomposition of the master is not proficient in their own work production efficiency is not clear, resulting in the actual curve higher than the planning curve.

2. Although, from July 12 to July 18, the actual curve is higher than the planned curve, the trend of the actual curve coincides with the plan curve, indicating that the production rate of the team members is constant.

3.7 months 19th, the actual curve fell back because the development group submitted the iteration version to the test as a result of iterative system testing.

4. The last working hours are still present, and there are problems in characterizing members ' hours.

Experience:

Through the study, the Burndown chart has a certain understanding. It achieves the overall project progress of the master, clearly shows the expected and actual work situation, is conducive to improve work efficiency.
