On Development, Measuring & Learning

Talk I gave for 5th Year engineers and Innovation students at Universidad Adolfo Ibañez, Santiago, Chile.

Transcript

1. ABOUT DEVELOPING MEASURING & LEARNING
2. @NGOLES
3. BACKGROUND • R&D at INRIA, France. • Mobile Games & Technology. • Geek. • Developer. • Just came back from Silicon Valley, 4 months developing a product there.
4. START
5. • Adapting. • Building Stuff early on. • Learning. Everything is an assumption. To validate our ideas. Change our shoes, while we are still running. TOPICS
6. • Coding. • Irrefutable truths. Ok, maybe just a bit. What works for me, may not work for you. • Mega Scale. i,e Facebook, Twitter, Instagram. NOT TOPICS
7. PART 1: DEVELOPMENT
8. MVP What’s a good MVP anyways?
9. “You want to build a huge ship, but instead of building the ship right from the beginning, you start by testing your idea with minimal design to see if it floats.”
11. • Simple. • Robust. Just the essence. Ok, it can crash from time to time... • Measurable. So you can learn from it. GOOD MVP
12. We need to move fast! Why such a rush?
13. • Use what you already know. i.e. Know Javascript? Build your iOS App MVP with Phonegap • Save time on repetitive tasks. ...and get used to do so! MOVING FASTER
14. TOOLS Heroku Test Flight Deploy instantly with git. Distribute iOS Apps to beta testers in seconds. Trello Agile collaboration tool. Hip-Chat Agile non-obtrusive team chat.
15. Auto Deploy v/s Heroku
16. before_migrate do template "#{release_path}/config/environments/#{app[:environment]}.rb" do source "#{release_path}/config/environments/chef_development.rb.erb" local true owner app[:deploy_user] group app[:deploy_user] mode '0400' variables(:environment_settings => app[:environment_settings].to_hash) end rvm_shell "Bundle install and assets precompile" do ruby_string "#{app[:ruby_ver]}@#{app[:gemset]}" cwd release_path user app[:deploy_user] group app[:deploy_user] # common_groups = %w{development test cucumber} # bundle install --deployment --path #{app[:app_root]}/shared/bundle --without #{common_groups.join(' ')} code %{ bundle install --path #{app[:app_root]}/shared/bundle } end end before_restart do rvm_shell "assets precompile" do ruby_string "#{app[:ruby_ver]}@#{app[:gemset]}" cwd release_path user app[:deploy_user] group app[:deploy_user] # TODO I could not set the environment via the builtin command. Does not look like it is getting passed to popen4 # So instead of `environment "RAILS_ENV" => app[:environment]` I have it in the code block code %{ export RAILS_ENV=#{app[:environment]} bundle exec rake assets:precompile } end end symlink_before_migrate({ "config/database.yml" => "config/database.yml", "config/environments/#{app[:environment]}.rb" => "config/environments/#{app[:environment]}.rb" }) after_restart do
17. #git push heroku master 1 line to deploy your Web App.
18. Lesson 1: Tools can save you time ... and money in the long run!
19. PART 2: MEASURING THE MVP
20. When? ... shall I wait?
21. Why? ... validated learning anyone?
22. “Build-Measure-Learn: How do you build the fastest ship? You try to build and test your hypothesis; you measure the result; and then you learn new knowledge that you can bring to your next ship design.”
23. What? ... App Downloads?... Page Views?
24. How? ... so many options!
25. TOOLS • Google Analytics • Crazy Egg Not only for Web Apps. Heatmaps! • Mix Panel 100% Real time analytics platform. • Optimizely A/B Testing you’ll actually use.
26. CONSIDERATIONS • Support • Real-time • Costs
27. Event Tracking Example
28. Track profits of a sale in your website ...using Google Analytics! <a href="#" onClick="_gaq.push(['_trackEvent', 'Purchases', 'profits', 'Awesome Item', 299]);"> ! Buy awesome stuff! </a> PS: You can use something like jQuery to make this more elegant.
29. [tracker trackEventWithCategory:@"UIAction" withAction:@"PlaySongButtonPress" withLabel:@"PlaySongButton" withValue:nil]; Track the touch of a play button in iOS ...using the Google Analytics iOS SDK!
30. Visualize and take action.
31. Lesson 2: Test everything ...the data allows you to learn and build what people really want.
32. THE END @NGOLES
