Standard Procedure is a very good card. Allowing for a hand-snoop as well as profit, Standard Procedure has a number of benefits.
Making bank: At 0 cost, and 2 credits per hit, the runner having at least 2 of the card you named, most likely Event or Resource, puts this in Hedge Fund range, and 3 hits is better than a Restructure.
Plan Ahead: Looking into the runner's hand tells you what tricks they might have. Combined with other tools like Kala Ghoda Real TV, the Corp can tell exactly when they have a scoring window.
Targeted Removal: Standard Procedure offers an absolutely brutal combo with Salem's Hospitality. Using a Standard Procedure and following up with the Hospitality offers a counterless way to take away the runner's tools.
Requires a successful run: slow runners may interfere with playing the card
