If the problem was the solution ? - nCraft 2016

We love the challenge of solving complex problems. But are we always sure to solve the right one?

This lightning talk wants to show how thinking about the problem statement can radically change the complexity of the solution.

With examples from history and sciences we will review some shifts in the problem vision and the impact they had. And how this mindset can apply in our day-to-day job.

3. PROBLEM ?
4. changing the problem perspective…
5. Wrong perspectives make Leads to Fought by complications accidental complexity simplicity Ockham razor principle
6. « Our job, as a software developer is to contains accidental complexity contain complexity
7. Wrong problem definition…
8. Wrong problem statement makes Leads to Fought by errors bugs tests
9. « TDD is a form of Property based testing is deductive reasoning inductive reasoning
10. does the problem even exists ?
11. Creating a problem Leads to Fought by of your own feature creep YAGNI
12. « Often the right solution is to not write code at all solution at all
13. solving the root cause, not the symptoms…
14. Solving symptoms is a Leads to Fought by temporary solution instability root cause analysis
15. « You need to be a problem founder before being a problem solver finder solver
16. Scaling is not linear in complexity…
17. Scaling with the Leads to Fought by same solution software collapse decoupling software engineering
18. Micro-services
19. « Exploration is searching for new solutions while exploitation is improving what already works. - Alan Key Exploration exploitation
20. Scalability implies entropie
21. Scaling without managing Leads to Fought by entropy software rot refactoring
22. « I’m not a great programmer; I’m just a good programmer with great habits - Martin Fowler habits great
23. Searching the solution in the technical field…
24. Searching solutions in the Leads to software with Fought by technical field no added value DDD
25. « You are not paid for the technical problem you solve, but for the business one business technical
26. Reinventing the [square] wheel…
27. Making your Leads to Fought by wheel bad implementation benchmarking
28. « So, no, you shouldn't reinvent the wheel. Unless you plan on learning more about wheels, that is. learning wheel - Jeff Atwood
29. « If I were given one hour to save the planet, I would spend 59 minutes defining the problem and on minute resolving it. -Albert Einstein 59 1
30. « Life is really simple, but we insist on making it complicated. -Confucius
