# Leading Technical Organizations
1. Technical organisations exist to provide the services and solutions to the problems of the business they support. Our actions should always reflect the needs of the business and the customer we serve
2. Culture > Tools. SRE is a mindset of ownership, responsibility and reliability, not just a job title.
3. Empower experts by removing roadblocks, not by micro-managing implementation.
4. AI can be a considerable force multiplier if used in the right ways and with the right risk frameworks.
