The student includes five supporting documents, which is in line with the requirement for three to five documents. However, the publication dates of these documents are missing, and they do not meet the criteria of being contemporary. While the documents are labeled clearly, they lack relevance and depth, primarily relying on corporate reports without external analyses or customer feedback. Additionally, the student fails to highlight key parts of the documents that directly relate to their IA, and there is no assessment of the validity and reliability of the sources. To enhance the quality of the IA, the student should incorporate a broader range of viewpoints and critically evaluate the supporting documents used.
