The document discusses collaboration challenges between marketing and IT functions when developing new products and services. It identifies a key barrier as the "translation barrier" where marketing and IT speak "different languages". The document also presents some mitigation tactics used by companies, such as having boundary staff that can translate between marketing and IT, using prototypes and user stories to facilitate joint work, and co-locating marketing and IT teams. The conclusion is that while there is no clear answer, approaches like cross-training staff, using agile development methods, and bringing the functions together may help overcome collaboration barriers.
