I did a talk that resulted in the http:://agilequittersmanifesto.org. It was tongue-in-cheek, a tough message that carries truths. This is a follow up from that moment, and I feel that we need to have some difficult conversations. This talk was presented at rubyfuza.org in February 2019.

Do we care rubyfuza 2019

  1. 1. aslam khan @aslamkhn rubyfuza DO WE CARE?
  2. 2. if you can’t handle the truth...
  3. 3. … you’re probably using JavaScript https://twitter.com/ossia/status/1085350967246086144?s=09
  4. 4. agile rabbit holes (agile africa conference 2018)
  5. 5. rabbit holes Failure does not lead to learning Quitting or continuing for the wrong reasons Tolerance for mediocrity Producing and consuming lies Denying and ignoring ignorance Unicorns chasing rainbows
  6. 6. Agile Quitters Manifesto We have unsuccessfully tried to teach people agile for a long time. Through this work we have come to value: Sleeping well at night over pretending to deliver value Personal integrity over having an agile certification XP over Scrum Anything really over "Scaled" Agile That is, while people believe the items on the right have value, there really is none whatsoever. We can't be bothered anymore, and are going back to coding. See ya! By Marcus Ahnve, greatly inspired by Aslam Khan. Source https://agilequittersmanifesto.org/
  7. 7. what I have observed The increasing distance between developer and customer which leads to a non-uniform design which is more complex than the problem that is visible as ambiguity, divergence and prolific miscommunication and we hide this mess behind CDF Certificate Driven Flow
  8. 8. we normalise deviant behaviour
  9. 9. and the response is NOT “We are software-artists” Artistry is a creative endeavour in response to a feeling about the state of self and/or the world. Engineering is a creative endeavour in response to a recognised problem in the world that needs to be solved.
  10. 10. Make space which leads to Protection of conceptual integrity that is visible as Frictionless Collaboration and shift from Costly “reuse and maintain” to cheaper “rip and replace” 4 things
  11. 11. Stop cramming and chasing features chase solving your unique, hard problems continually trend to be better at continuous delivery protect your product Your genuinely unique problems are …. well, unique cultivate a culture of toolsmiths Plan when you need to plan Rushing to catch up is the fastest way to fall behind Make space 1/4
  12. 12. THINK CAREFULLY (slow) ACT PRECISELY (fast) confirm / discard Make space Deliver continuously (automate everything) Learn continuously Your job is probably the best free education you can get - don’t waste it WARNING These are often in tension 1/4
  13. 13. The single most important aspect of your design Omit features than have independent, uncoordinated ideas Is not achieved by democracy “A camel is a horse designed by a committee” Comes from the mind of one or very few The program manager (this is not the traditional “project management” style) is the champion and protector of conceptual integrity Conceptual integrity (see Fred Brookes’ Mythical Man Month essays) 2/4
  14. 14. Conceptual integrity 2/4
  15. 15. Face to face is faster and more reliable than anything else When everyone can provide the same response to This is why we want to do that … .. and so we are busy with this! “I told you so” is banned Voice and receive all feedback, equally Respect and support the decision Have the courage to change when it does not play out as planned Move around Frictionless Collaboration 3/4
  16. 16. Build for use before reuse Achieving reuse is hard, very hard Design to rip and replace Reality check #1: maintenance is incredibly difficult and costly Reality check #2: designing for parts to be discarded is hard but cheaper Refactor mercilessly for both: “maintain” & “rip and replace” “for each desired change, make the change easy (warning: this may be hard), then make the easy change.” https://twitter.com/KentBeck/status/250733358307500032 Rip and Replace 4/4
  17. 17. We write code to ... move data from a database to a user interface and back again integrate with another system Actually, we write code that ... moves data from one place to another changes data from one shape to another Most times we need pipelines of transformations and filters it is easier to rip and replace the parts of pipelines than disentangle object graphs, class hierarchies, glued layers and deeply nested procedure calls Rip and Replace 4/4
  18. 18. Make space which leads to Protection of conceptual integrity that is visible as Frictionless Collaboration and shift from Costly “reuse and maintain” to cheaper “rip and replace” 4 things
  19. 19. You get there by ... Being humble, respectful and courageous Being disciplined Being self-aware Not being entitled Not abusing your privilege Being humane in your actions so that you sleep restfully
  20. 20. Make space? Protect conceptual integrity? Commit to frictionless collaboration? Build to rip and replace? thank you Do you care enough to aslam khan @aslamkhn And if you do … you will find yourself being truly useful and you will be happier for it
