Aer Lingus researched a number of learning management systems from other providers but found that proprietary offerings varied in what they could do and were not as flexible as open source solutions. Moodle satisfied requirements in terms of features and functionality, but also had the open source flexibility which allowed Aer Lingus to customise it to suit their own needs. The reporting aspect of Moodle also meant that Aer Lingus could meet one of their key requirements—the ability to report on user activity to demonstrate regulatory compliance to the relevant authorities. Other requirements included security and the ability to deliver third-party content.
