text: what are the 9 types of waste under kaizen?   i have only ever seen 7 types cited.  below is a description.  seeing waste during a kaizen blitz  project team members may not be used to thinking in terms of waste and value in their individual work, their workgroup, and workstream so an emphasis on understanding the 7 types of waste in the project setting is essential. examples of wastes within the work of a project team include:  overproduction due to unclear requirements from the upstream process, waiting time for information from another project team member before work can be completed, inventory of projects or project tasks that are in process, motion of switching from one multi-task activity to another, defects and rework loops, and transportation and the delays and loss of information caused by hand-offs.  then there is processing waste (which some call over-processing) whenever you are using a crude tool to accomplish a task rather than the best available that may exist somewhere else in the workstream of the project, this is processing waste.
