Next time you start building a website, here's what you're going to do:

• You're going to build an install profile
• You're going to write a Drush Make file (forget about randomly patched modules in the repository)
• You're going to export your configuration to features
• You're going to start writing update functions for each deploy
• You’re going to establish a proper workflow for your team

Not sure what that means? We'll explain.
Not sure how? We'll show you.

...
Okay? Good.

The promised land that awaits you:

• Predictable development workflow
• Reusable components across projects
• Better tracking of configuration changes
• Easier onboarding of additional contributors
• Better integration with automated testing
