Ken Schwaber, the founder of Scrum, has a blog. In it, someone mentioned that Scrum is changing. Ken responded:
If you change the Scrum framework you just simply aren’t using Scrum and are probably canceling some of its most important benefits.
Thank you Ken! I wholeheartedly agree. Every CSM class I teach, I emphasize the complete nature of Scrum as a single tool, not a collection of tools. Learning Scrum is about learning the tool, not learning how to pick and choose pieces of a tool. Let’s explore this metaphor of Scrum as a tool.
Consider a hammer. A hammer is ideally suited for pounding nails into wood. It has two parts: a head and a handle. If you take the parts and use them separately, they can still be used for pounding nails into wood… but they are very ineffective compared to the hammer (although better than using your bare fist). It is non-sensical to decompose the hammer and try to use the pieces separately. However, a hammer is not suited to other purposes such as driving screws or cutting wood. It’s perfection is not just in its form, but also in its proper application. A hammer works through a balanced combination of leverage and momentum.
Scrum is like a hammer. It has parts (daily Scrum, Sprints, ScrumMaster, etc.), but taking the parts and trying to use them separately is… you guessed it… non-sensical. The parts of Scrum combine to be an extremely effective tool for new product development. Just like a hammer, there are things you wouldn’t want to do with Scrum such as manufacturing or painting a wall. (We might not all agree on the limits of the use of Scrum… that’s something for another article.) Scrum works through a combination of pressure on the organization and “inspect and adapt” (continuous improvement).
Please. Don’t modify Scrum. If you must change things about Scrum, please stop calling it Scrum.
