The student has included five supporting documents in the work, ensuring that the criterion of including three to five supporting documents is met. The supporting documents are contemporary, published in the years 2022 and 2023, meeting the requirement of being within a maximum of three years prior to the submission of the IA. However, the clear labeling of each document as "Supporting document 1", "Supporting document 2", etc., was not ensured, which is a requirement that the student could have fulfilled. Additionally, the student has not included any transcripts of video or audio material, fulfilling the subcriterion of having a maximum of one of such supporting documents. The supporting documents are relevant and sufficiently in-depth, as they focus on Ryanair and its employee motivation, and provide a range of ideas and views regarding the topic. However, the student did not provide a thorough analysis of the validity and reliability of the documents, which could have been addressed in the methodology by considering elements like bias, date of publication, and views explored.
