Stage 0 – Just An idea
• Focus on Features
• Trying to solve a problem
• Anything is possible
• Scope creep
Join the Conversation #hackday @ChrisBriggsy
Stage 1 – Proof of concept
• Build a proof of concept
• Core functionality working
• Probably buggy
• Flesh the app out
Join the Conversation #hackday @ChrisBriggsy
Stage 2 – Beta testing
• Start gathering data
• Start listening to user
feedback
• Realise application is fragile
• Improve the app

Stage 3 – Set it loose
• Release in to the app store
• Continue gathering data
• Continue listening to user
feedback
• Continue to Improve the app
• Sink or Swim

Stage 4 – Improving the app by metrics
• The app has been out for a while
• Focus on visibility into the application
• Errors logged + reports
• End user usage
• Performance Metrics
• Store rating trends
• Feature X is not the key feature of the
app but used by 75% of users
• Therefore: We should spend additional time to
polish feature x
