Agiliti had a very nice marketing communication design system at their inception but went internal desktop publishing. Over the years, everything had just turned into a mishmash of brochures, datasheets, white papers, none resembling the other. They could have all come from a different company (except for the logo). In conjunction with a writer associate, my assignment was to get them back on track with a system similar to what they started out with.
Note: Once there’s a system, many companies can produce internally as long as staff follows the rules/guidelines.
