@codescrum Application Example based on Gov.uk public code This talk shows how we can implement a custom customer service flow based on the SmartAnswers module from the GOV.UK project. Jairo Diaz @codescrum 

@codescrum Requirement ● Implement a pension advice tool: Start Question 1 Question 2 Oucome 1 Question 4 Oucome 2 Oucome 3 Oucome 4

@codescrum Can we reuse? 1. Spike: Install and implement a simple flow 2. Review code 3. Reuse code 

@codescrum Step 1. Test Simple Flow ● Github project: alphagov / smart-answers-stack ● Check Readme.md
