This podcast was authored by John seddon and based on work he co-authored with Brendan O'Donovan. It is a masterful re-examination of lean in the light of the latest learning in systems thinking. It is worth a read by anyone who is using lean in their organisation or considering introducing lean tools and techniques into their service organisation.
Afterwards you will almost certainly want to step back, pause and think again.
