Todays web and app projects are not just pieces of code.Every change a developer creates can affect performance, usability,stability and even the relationship to the customer.In this talk I will discuss the necessity for agile development teams to havea better understanding of what makes their product really great in the endand how recurring conceptual phases can help in this. Presented at T3Con15 in Amsterdam

1. Improving conceptual understanding in development

Would you make assumptions
about a dragon?

3. Chapters
I. Dungeons & Dragons & Conceptual understanding
II. A light through the fog of requirements
III. Evade traps with agile methods
IV. Gain experience and grow your strengths
V. Slay the dragon of Golive and retrieve it’s treasures

4. Why is conceptual
understanding important?

5. Our web projects are not
Just pieces of code
Fluffy mythical
creatures

6. COMPLEX
Websites and apps are

7. Idea & final result
Can look similar but the result might behave unexpected

8. So, why are they complex?

9. People working together
Team:
„A group of people with individual views
on the same(?) thing“

10. Technology
Dependencies
Continuous delivery
Performance
Scalability

11. Next:
The real complexity

12. People must actually be able
to use your product!

13. The connection to
Pen & Paper games

14. Parts of a Pen & Paper game
Game master (Storyteller, Visionary, PO)
2-6 Adventurers (Different strengths and personalities)
Space where everyone sits together
Books describing the rules of the game
Motivation
Common goal
Sounds like a project

15. How people play
I. Game master describes the situation
II. Everyone synchronizes their view
III. Player do actions
IV. Game master explains results according to the story and the rules
V. Players evaluate result and adapt
VI. Start again from step I.
Sounds like a Sprint

16. II. The fog of requirements

17. From far a forest might look
very nice
It will lead you to your
goal and reveal the dragon

18. Beware: There is always
something lurking there!
Shifting priorities
Described workflows don’t fit anymore
External dependencies
Demanding stakeholders
Technical debts

19. What makes a product usable?
Customised solutions
Well thought out workflows
Good performance

20. Clients are used to bad
solutions
And sometimes ask for more of it

21. III. Evade traps with agile
methods

22. Daily stand-up
Synchronize

23. Reviews
Do internal reviews and user testing
Let developers present their work
Invite the client
Check for dents in your armors

24. Keep some slack in your
planning
Improvements need time too
Sharpen your weapons

25. Don’t kill ideas with
overcomplicated processes
A process can be bent
Frameworks adapted

26. Refresh a projects vision
regularly
Sometimes the trees block your view on the dragon

27. IV. Gain experience and grow
your strengths

28. Retrospectives
Talk about your processes
Practise communication
Grow as a team

29. Miscommunication is
expensive

30. Every change can have
undesired effects
Performance degradation
Usability
Stability issues
Relationship with the client

31. There are already some
solutions
Automated testing (stability & performance)
A/B testing for user experience

32. Sadly, no automatic tests for editors
efficiency or clients happiness :(

33. Many developers don’t know
what clients are doing

34. Ignorance?
I don’t think so
(maybe sometimes)

35. Fostering project ownership

36. Empathy
Client has bad experience?
Feel the urge to improve it
Find sustainable solutions
Work with the client
Try to understand the client
Get to know the client (he’s not the dragon)

37. As a developer you can
See tasks as challenge
Try to see your work from a different point of view
Involve in shaping a project
Defend your ideas and concepts
Teach others
Cooperate & ask for help
Write down or draw what you know

38. Get coaching
Enable developers
Let coaches coach, not do the work
Help developers not to depend on coaches

39. V. Slay the dragon of Golive
and retrieve it’s treasures

40. Things might be different
than expected
Is the dragon hungry?
Did he have enough sleep?
Is he unhappy?
Assumptions might be deadly!

41. Thank you!
