This article has some reasonable core values: http://www.stefankendall.com/2012/10/core-values.html
(NOTE: This text copied from URL above, not mine)
- Working longer is not working harder. Go home.
- 40 hours includes the commute.
- Resist the urge to call a meeting.
- Consensus is bullshit. Do what’s best for the company.
- We will not ship shit.
- If it’s hard to use, it hurts the product, the company, and our reputation.
- You will do customer service for the products you create.
- We will work in public. Our code, our designs, and our ideas are not our business. We are our business. Our products are our business. Customers are our business.
- People are expensive. We will strive to keep individuals working for the customer, and not on the business.
- Efficiency is everything. We will remove obstructions.
- We will not celebrate. Every day will be awesome, or we stop what we’re doing and make it awesome. Cake is for gazelles, and we are lions.
- We will enjoy our work, our products, and our lives. We will make work awesome.
- We will be lean. We will NOT ignore problems, and we will swarm when issues arise.
- You are an adult. You will manage your own machine and tools.
I think this list is very reasonable however there is one I am against. "We will not celebrate". This is quite wrong. One of the most important things in a creative environment is closure. There should be an end point. This end point might be a release, maybe even as often as 2 weeks, or maybe 6 weeks. But at that point, when that project, feature, or release is complete you should most definitely celebrate.
One note in particular above - "You are an adult. You will manage your own machine and tools" - WHY do companies think it is a good idea to take over.
