The student has effectively identified sustainability as the key concept in the IA, which is clearly indicated on the title page and aligns with the research question focused on H&M's financial feasibility in transforming to sustainable fashion. The investigation is centered on H&M, maintaining a clear focus on a single business while discussing industry-wide sustainability issues and their direct impact on the company. Additionally, the student provides comprehensive background information about H&M and outlines the issue under investigation, including the methodology used to analyze financial implications. However, the research question lacks clarity regarding its temporal focus, and the connection between sustainability and H&M's practices could have been more explicitly articulated throughout the IA.
