Had source code control, albeit printed manual audited to the nth degree with any production changes having to be fully audited and signed off and compared with original with light boxes twice by separate people level of SCC. Yeah experienced that back in the 80's, it got easier though. As for standards you would see from one company to another - early days and lucky to have separate department use same standards. So payroll would have different standards than marketing, but separate ecosystems and less of an issue, beyond team cultural changes and analysts quirks. But then, standards change over time and become usurped. So could very well ask the same question in 20 years time as the approach is always changing. May even be a call for C programmers then.
