Portfolio Kanban System: A Silver Bullet or Golden Hammer?

Introduction

The title may seem like a clickbait, but is actually not. I do seriously believe that there are a few “silver bullets” to being lean. Equally, I do also believe that in the knowledge industry, a kanban system, a supposed visual way of managing the flow of value, is a modern day golden hammer for many i.e. very overrated providing a false sense of assurance of being lean.
