Huh, it's a kind of a very abstract question. Each business case is unique and has its own needs / requirements, whatever. There are no well-trodden paths suitable for everyone. Anyway, we have 6 principles we advise our clients and partners to follow:

1. Think as if you were your customer .  Any action taken and decision made should be customer-centric. This would help scale business and add more value.

2. Each team member is responsible for his / her tasks. End-to-end responsibility allows deliver quality results and perk up a team. 

3. Continuous enhancement and feedback as a background for further improvements.  DevOps philosophy believes in CI/CD, which stands for continuous implementation and development, allowing the product/application/software to become more user-friendly from all sides - both technical and personal sides. 

4. Automate unautomatable.  Automation allows increasing productivity of development and eliminating of repeatable manual tasks, causing errors and downtimes. 

5. Well-tuned collaboration among ALL teams  (yes, it concerns everyone in the organization). Gaps in communication cause further failures in successful operations. 

6. To provide the best quality of a deliverable - test and monitor continuously.  Without proper testing and monitoring, even the best engineer in the world won't be able to deliver an stable operation.
