1. Critical thinking: ABL engineers understand the "why" behind all design decisions, operational events and test outcomes.  

2. Ability to deal with ambiguity: there is no roadmap and ABL engineers must be comfortable defining their own pathway to an objective. 

3. End-to-end ownership: projects are delivered fully complete and ready for flight; there is no one to pick up the slack of partially complete work.
