Conclusion: All organisations are multilingual, and most, more so than may seem apparent on the surface. A systematic effort to minimise the likelihood and impact of communication problems can lead to significant cost savings, productivity improvements, and improvement of staff morale. Data quality, the quality of system integration, and the quality of product or system specifications often turn out to be the Achilles’ heel. It is a mistake to assume that the biggest potential for misunderstandings is confined to the communication between business units and the internal IT department. Whilst some IT departments could certainly benefit from learning to speak the language used by the rest of the business, the same conclusion applies to all other business units.
