> what is the ROI of building and maintaining their own solution versus biting the bullet and pivoting so they can use pre-existing products? Using made-up numbers, if you have 50000 employees using source control at your company and a custom solution would improve their productivity by 0.1%, having a team of 10 building such a solution is positive ROI. In contrast, if you have 1000 employees, it would be a negative ROI. This is why it's worth doing if you're Google or Facebook but not most other companies.
