Deployment to prod by one click

Ability to scale project team

Code Driven Development

What should be moved to code?

Use just the exportable friendly modules

- Views

Typical issues

Using equal environments

Prod = Stage = Integration = Local dev

Code review inside the team

Developers do code review for each other

- Use common approaches for features

- Knowledge exchange inside the team

- Better quality of code

- Increase responsibility for review code

DB manage approach

Use always latest prod db

Preparing prod db for use in development

Daily db backup script from prod

All enviroments should use sinle DB

Profits after using CodeDrivenWorkflow

Fix errors on early phase

Reduce time for bugfixing

Minimizing the impact of the human factor

Simplified everyday deployment
