The student included four supporting documents in the IA, which effectively explored various aspects of Dunkin's rebranding strategy, enhancing the analysis of its impact on profitability. Each document is clearly labeled, allowing for easy reference and organization throughout the work. The supporting documents are relevant and sufficiently in-depth, presenting a range of ideas and perspectives regarding the topic. However, there is no assessment of the validity and reliability of these documents, which is a notable omission in the methodology. Additionally, the attachments of the supporting documents were not provided, making it impossible to evaluate their contemporaneity or specific content details.
