Several years ago I was looking for examples using the generalization / specialization technique with use cases. They are not easier to find. And they are typically limited to a use case diagram like the two below. This article provides examples of both the diagrams and the scenarios for a future gas station business.

In Part 1 of this series John Seddon argued that Agile, as practiced, is bereft of knowledge, hence its ubiquitous failure. Here he argues that ‘get knowledge’ is the starting-place for effective change.

Part 2: Knowledge: the prerequisite for profound change

It may seem heretical to suggest that we make change without knowledge, but, as Deming pointed out, experience is not equivalent to knowledge; you can spend 20 years in an organisation without knowing how to change it for the better. Leaders, clients and stakeholders describe requirements or problems to solve on the basis of their current world view, governed by information from their current control systems, but what if their world view is flawed? What if there are bigger and different problems to solve?

Five S can be applied in any work environment and prepares a work area for a follow-on Lean process improvement effort. In this case, 5S prepares my garage for Lean process improvement in doing home activities like automobile maintenance, appliance repair, and hobbies like gardening and woodworking. But, remember the preparation benefit is only realized if 5S is sustained. As I said I am the worst (ugly) in keeping the “new world order” in my garage.
