A burn down chart tracks work remaining over time while burn up charts like the CFD track the growth (or shrinkage) of work in certain states over time. In agile software development, when teams use kanban methodology, the cumulative flow diagram shows the number of active items in each column on a kanban board.
The lead time shows the amount of elapsed time from a chunk of work or story entering the backlog, to the end of the iteration or release. [13] A smaller lead time means that the process is more effective and the project team is more productive. [13] Lead time is also the saved time by starting an activity before its predecessor is completed.
The project has two critical paths: activities B and C, or A, D, and F – giving a minimum project time of 7 months with fast tracking. Activity E is sub-critical, and has a float of 1 month. The critical path method ( CPM ), or critical path analysis ( CPA ), is an algorithm for scheduling a set of project activities. [ 1 ]
Streamgraph (type of area chart) width; color; time (flow) A type of stacked area chart that is displaced around a central axis, resulting in a flowing shape. Unlike a traditional stacked area chart in which the layers are stacked on top of an axis, in a streamgraph the layers are positioned to minimize their "wiggle".
Value-stream mapping has supporting methods that are often used in lean environments to analyze and design flows at the system level (across multiple processes).. Although value-stream mapping is often associated with manufacturing, it is also used in logistics, supply chain, service related industries, healthcare, [5] [6] software development, [7] [8] product development, [9] project ...
The above eight rules apply to a chart of a variable value. A second chart, the moving range chart, can also be used but only with rules 1, 2, 3 and 4. Such a chart plots a graph of the maximum value - minimum value of N adjacent points against the time sample of the range.
As with the ¯ and s and individuals control charts, the ¯ chart is only valid if the within-sample variability is constant. [4] Thus, the R chart is examined before the x ¯ {\displaystyle {\bar {x}}} chart; if the R chart indicates the sample variability is in statistical control, then the x ¯ {\displaystyle {\bar {x}}} chart is examined to ...
A supply chain responsiveness matrix is a tool that is used to analyze inventory and lead time within an organization. The matrix is one of a number of value stream mapping tools. [1] The matrix is represented by showing lead time along the x-axis and inventory along the y-axis. The result shows where slow moving stock resides.
