I agree for a system in steady state. The manufacturing branch of constraints understand that they appear to move until the system is in stready state. Which is why they throttle systems as they bring them up.

Does the complexity arise from the fact that they move?

Great write up. Would make a nice experience report. Have you tried

to for fantastic conversations over the holiday, helping me understand links between enabling constraints, evolution, energy, uncertainty and fitness landscapes (ecologies), community of needs/solutions. Now for practice!

given-when-then or then-when-given resonates with expert systems and knowledge engineering and their IF-THEN rules, or do they?

In other words, you can use it to mine insights that form the starting point for “hunt the value”. ;-)

Interesting. Could you share how you did it? What was the context? What did you do? What was the result?

Thanks Roger. Had a quick look. The process sounds identical (work backwards). The format is different but worth a deeper look I think.

I disagree that every example has value. Break the model is a tool to find the examples that do have value. I agree stories are the investment to implement a set of stories, i.e. they are formed when we know what the examples are, otherwise too much uncertainty into sprint.

I agree. Your post aligns with the conversation that and I had last week. Example mapping as a tool to express requirements in the complex domain. It is not a business analysis tool helping the BA gain the knowledge in the first place in the complicated domain.

Use Given When Then starting with the Output (Then) and work backwards. Each given becomes a then. Each (internally generated) when becomes a then. It’s super fast and collaborative, requires no training. Did it two weeks ago.

Technical debt is a socio-technical constraint. It’s the code base PLUS the team. If the team lacks refactoring/TDD skills, that’s debt too.

Great discussion. TDD is one of the first examples of real options. Also, if you “work backwards”, abstraction naturally occurs.

How do you use EM to express user need and business value?

I’m confused. The point of finding the value is that you can then slice the requirements (by value) rather than functionality. How do you slice functionality like “view order”?

Not sure how we’ve deviated. I am trying to understand the customer need you intend to satisfy. :-)

So “a need to reorder”, but what is what need does “print receipt” satisfy. Do we have a need for “logging in” or “Need to establish identity”? The former is a solution, the latter a need. A need may be satisfied in many ways.

So why do you want to view your last order? What need are you trying to satisfy? Still about functionality (output) rather than customer value (outcome)
