I get where these places are coming from - it is really easy to get started implementing these workflows in Excel and just grow it from there. But they are really fragile and hard to audit - who knows whether they work correctly even now! And it's highly likely that only very few people actually understand how they work and how to maintain and extend them. Great for job security, but there is going to be a lot of problems when the people who know them are not available anymore. Better to transition the embedded knowledge to something more maintainable as long as it's still possible.
