Unevenness or Mura: What Is It?

Unevenness or Mura in an operation is when a process has excessive wait time followed by excessively busy periods.  In other words, team-mates are forced to “hurry and then wait”.

Not only does Unevenness in a process reduce morale, it is often a wasteful use of team-mates time and resources.

Unevenness can be reduced by using Line Balancing, working towards One Piece Flow, and reducing Re-Work in a process.
