How I approach problems

[coderbyheart]

I should try to explain how I approach problems I am presented:

1. Look at the problem from the user's point of view.
   → write down the User Story, this becomes the source for the acceptance test(s).
2. Collect all interaction within the system that are affected, and not down new ones. Use Domain Driven Design principles: which Actor(s) cause which Entities to change/appear through which Events?
   → write it down as a Domain Story.
3. Collect all the systems that are affected by the problem, and figure out which existing systems to re-use and modify and which new systems to introduce to solve it.
   → write it down as a technical concept.
4. Prioritize the needed changes and find the smallest useful set to get to a working release.
   → Repeat until done.
