• First rule. You must understand the rules of scuba diving. If you don’t know or understand the rules of scuba diving, go to the second rule.
• The second rule is that you never dive alone.
• The third rule is that you always keep close enough to each other to perform a rescue of any kind.
• The forth rule is that you signal each other and therefor know each other’s signals. Underwater, communication is key.
• The fifth rule is that you tell the others, for example, when you don’t feel well. The others want to know when you emotionally don’t feel well. Whenever you are insecure, you tell them. This is hard.
• The sixth rule is that you don’t violate earlier agreed upon rules.
• The seventh rule is that given rules will be eclipsed the moment any form of panic occurs, you will restore the rules using rationalism first, pragmatism next but emotional feelings last. No matter what.
• The eighth rule is that the seventh rule is key to survival.

These rules make scuba diving an excellent learning school for software development project managers.
