A flawed idea, from a big consulting company, is a poisoned seed that once planted in the mind of inexperienced practitioners can spread misinformation and distort people’s understanding.
Let’s turn this poisoned seed into an opportunity to reflect on the foundations of lean and agile, and deepen our understanding.
In 2016 Gartner published
a diagram that combines ideas from Design thinking, Lean Startup, and Agile.
I was initially attracted because it combines different approaches and practices instead of contrasting them, and I also overlooked the three underlying flawed ideas.
Those flawed ideas, planted in the mind of inexperienced practitioners, grew into a new lean/agile waterfall that is even more evident in the derivative diagrams.
This below is a simplified diagram that highlights the flawed areas:
It should be read from left to right, from the initial product need/goal (left) to the product delivery and operation (right). The overall process is a sequence of sub-processes. Each sub-process has its feedback loops. Sub-processes are connected by a loose feedback loop, with the main process flowing sequentially from left to right.
