Every company ends up running a software factory, whether it planned to or not.
The first shift is who builds. People inside the business can now make the tool they need without waiting in a queue. The second shift matters more, and it is about what gets built.
You have a list of small improvements nobody ever approved. A form that saves two minutes. A check that catches one error a month. Each one moves the needle by 1%, so the effort never earns its place.
Building costs almost nothing now, so those fixes get done anyway. An afternoon does not need a business case.
Stack enough of them and the company runs differently. Approvals move faster, errors stop reaching customers, and your team stops working around its own software. That becomes the new market standard, and customers start expecting it everywhere.
