Don't want to stir up a discussion here, but if you have a disorganized place you have waste, if you don't have anything sorted around your work space, you are creating waste, if you don't standardize the task and everybody does the activity however they prefer, you are going to create waste eventually, and I can keep going on with the list...
And bad processes are bad processes because of the lack of 5s vision when they are being designed.
Everytime we work in a continuous improvement project and we are designing work spaces, it is crucial for us to use 5S. That's the way you assure waste will be controlled...You design a space that will hold just the amount you need, closer to where you need it, just to hold the object you need, easy to reach, and easy to keep tidy and clean.
I don't like to see management, processes and techniques as bullets points. A good designed process will have lean concepts, 5s techniques, constraint management theories, and any other thing that may work and help it to be better. Process is no longer just a series of steps to make something anymore...it deals with a little bit more.
