Classification

Analyzing/Trending (AT)

Tool description

A value/non-value-added cycle time chart displays all activities and the cycle time required from the start point to the stop point of a process. The intent of this tool is to identify non-value-added activities such as lengthy delays, redundant or time-wasting activities, or excessive reviews and approvals. The chart should be constructed by a team that owns the process. Participants have a good understanding of the activities and therefore are best suited to collectively reduce cycle time of the overall process.

Typical application

  • To identify non-value-added activities and excessive delay times in a process.

  • To draw a detailed chart for the purpose of completing redesign, problem resolution, and cycle-time reduction activities.

  • To capture the "as is" process flow in order to have a common understanding of the process for further problem-solving efforts.

Problem-solving phase

Step-by-step procedure

  • STEP 1 The team facilitator assembles a team that consists of representatives (process owners) of the process to be charted. Flip charts or a white-board is needed to draw the chart.

  • STEP 2 The team determines the start and stop points of the process. The appropriate scale of time to be used is also determined.

  • STEP 3 Using the team-provided input, the team facilitator sequentially scales activities, value-added and non-value-added, above and below a drawn line, showing sequence numbers of activities and how much time each activity takes. See example Department Budgeting Process.

  • STEP 4 Next, the team checks the chart for completeness, correct activity sequence, and stated cycle times. Non-value-added activities are shaded in as shown in the example.

  • STEP 5 Finally, the chart is dated and presented to interested parties for further action.
