Nothing these days is done in one place, by one person, beginning to end. There is always a process in place, a chain of events that has to all work together in a co-ordinated manner to optimise the outcome.
We all know that old cliché, a chain is only as strong as its weakest link.
This is how it is with any process; it is limited in output by its weakest link.
Therefore, rather than spending resources in vain attempts to boost process performance by doubling down on the obvious bits that work well, find the weak link, fix it, then move on.
Eli Goldratt, the brain behind the Theory of Constraints, wrote a book called “The Goal” to articulate his theories in simple form. Boiled down in the book is a story of reverse engineering the process chain in a mythical factory. The management identifies the weakest link, works with it until it is no longer the weakest link, then moves on to the next identified target, now the weakest link in an improved process chain. This is an ongoing process of continuous improvement.
As Aiden Kavanagh, one of the best ‘Lean Thinking’ implementers I have seen in my travels put it succinctly in a comment on a previous post: ‘Tune the system to the pace of the bottle neck and make sure everything else has capacity to make sure the bottle neck never stops’
Is this how your improvement initiatives work, or are you continually making investments in new shiny things that always seem unable to deliver the promised outcomes?
