Pacing

The number of obstacles you require the PCs to overcome for an objective depends partly on the complexity of the infiltration. For shorter infiltrations, use fewer and lower-IP obstacles; for a longer, more complex heist, you can add more obstacles with greater complexity. Also, bear in mind how many checks the PCs will need to attempt to complete their obstacles. An objective with mostly low-IP group obstacles will move quickly because only a few rolls are required, compared to one with mostly individual obstacles that each PC needs to roll separately for.
