At GE HealthCare I learned how enterprise commercial systems actually work at scale

At GE HealthCare I learned how enterprise commercial systems actually work at scale. Some of what I took from that transferred. Some of it didn't.

What transferred.

Forecast discipline. Big enterprises run forecasts to the dollar. The habit of saying I'll close this much next quarter and actually closing close to it never leaves you. Operators who can forecast accurately are rare.

KPI design. Knowing which metric to put on the wall, and which 27 to ignore, is a real skill. A lot of operator businesses track too many things and act on too few.

Cross-functional alignment. Getting sales, ops, finance, and marketing pointing the same direction is a daily job at GE. It's an underdeveloped muscle in most smaller businesses.

What didn't transfer.

Budget logic. In a large enterprise, more headcount equals more output. As an operator, more headcount usually equals more drag. That took time to unlearn.

Stakeholder navigation. Spending 40% of your week aligning peers makes sense in a 50,000-person company. It will slow you down in a 5-person team. Operators decide and move.

Risk tolerance. Large enterprises teach you to mitigate. Operators have to ship. The same instinct that protects you in a big company will paralyze you when you're running a smaller one.

The skills are real. The mental model has to be rebuilt.
