A proposal

the team collaborates with the business to achieve the goals (it's partnernship relation)

Everyone is responsible for their own work (but we are also looking after each other)

Do not be afraid to deliver software. Focus on minimising potential issues

We should keep improving as a team and always find a better way

Being in charge of a project/ticket doesn't mean forgetting that we are part of one company. Support your colleagues!

Never stop learning, and helping others to grow

All team members should be able to work on the code base (at various speed and level of competence)
