Teaching a team of hardware engineers moonlighting as software guys to replace ZIP files and "version[1..n]_backup_2_reallyfinal.c" type filenames on a network

Teaching a team of hardware engineers moonlighting as software guys to replace ZIP files and "version[1..n]_backup_2_reallyfinal.c" type filenames on a network share with proper version control. Then static analysis and CI. Then the supportive manager left, to be replaced with a new manager (one of the aforementioned hardware guys "promoted out of mischief) hellbent on going back to the "old, better way". "Why should you get £1000 a year from capital expenditure just to keep our static analysis licence! You should write good code to begin with! Otherwise why did you get hired? Are you incompetent?" Some problems are just unsolvable.
