Usability refers to the principle that products should be designed to accommodate the typical understanding and abilities of their user communities, along with a consensus on the users' preferences. The usability study discussed in this paper was a supplementary project to existing research regarding childbirth decisions after a cesarean section. This research builds on evidence that the preferences of women in this situation are often not fully recognized, either by themselves or by obstetric practitioners. Additionally, it supports the objectives of various national and private healthcare organizations aimed at improving the effectiveness of medical decision-making.
