The Inka are responsible for a significant number of practices that are now well-spread all over the world, from culinary habits to sports and to communications.
The Inka never developed a writing system. Instead, officials used “khipu.” Devices made of coloured strings knotted in various ways. Khipu were used to record census data, the movements of people and goods throughout thr empire and religious and military information. The officials who managed the khipu were known as khipucamayuc.
Data gathering, sharing and storing was already an issue back then and they managed to master it with knots and ropes. A reminder that in comms management, simplicity remains key to sustainability and effectiveness.
