A big thanks to Dr. Kromm for a speedy and comprehensive answer.

I do have a follow up question: What about the phase of Preparing?

For when the action heroes get hold of the tools, vehicles, guns, wierd equipment, hacker assistance for records to back up fake IDs they need to pull off the plan?

Strictly put this shold come in between the Plan and Execution. But the scenario I'm planning may have some of these Preparation scenes happen while they're gathering intel to begin with, fot thinghs they know they need (recruiting the help af a hacker).
Timing may not be the greatest issue regarding the Action: Exploits system.

However the mechanics?
Something along the lines of: If the Plan requires certain equipment Executing is is modified by BAD but Complementary Skills can offset this penalty by actually getting these things?
Say the infiltration plans for two guys to dress up as electricians and act as they are there to fix a problem, and in the proces plant a bug or sabotage the alarm or whatever.
So they need a van from the electric company, tolls and uniforms, fake work orders. Getting these things sound like Preparing to me, or is it covered somehwere else I just haven't seen?
