“An opportunity opens up to transform your software into something more expressive and versatile than you expected. This can mean new features or it can just mean the replacement of a big chunk of rigid code with a simple, flexible expression of a deeper model. While this does not happen every day, it is so valuable when it does come up that the opportunity needs to be recognized and grasped.”

Summary
• Consider using the Web before you start reimplementing it
• Consider designing for replaceability and deployability
• Consider automating boring things including PaaS setup and deployment pipelines
• Consider using different change patterns for your context
