The student included three supporting documents in the IA, which consist of balance sheets, an interview with the CEO, and relevant research papers, effectively providing a foundation for analysis. Each document is clearly labeled, enhancing clarity and organization. However, the student did not provide a bibliography or a list of the supporting documents, making it impossible to assess their contemporary relevance and validity. Additionally, while the documents are relevant and in-depth, the student failed to highlight key parts or assess the validity and reliability of these documents. Overall, while the supporting documents contribute a range of ideas and views regarding sustainability, improvements are needed in documentation and analysis.
