IB Business Management SL Internal Assessment Example

The student keeps sustainability as a clear lens throughout the investigation.

The student makes a sustained connection to BMW’s i5 launch, strategy, competition, and reported performance.

The student shows a solid understanding of how environmental, social, and economic considerations can interact in a business context.

The analysis sometimes stays at the level of assertion rather than fully testing the sustainability claims against evidence.

The student sometimes generalizes from BMW as a whole rather than isolating the i5’s specific contribution.

The trade-offs and tensions within sustainability are not examined as deeply as the benefits.

The student selects five supporting documents, which gives the investigation a relevant core evidence base.

The source set includes a direct BMW launch source and an external market perspective, which improves relevance and variety.

The student's documents are generally related to the research question and include launch details, sustainability features, competition, and financial context.

Several sources are BMW corporate or press materials, so the evidence base is somewhat narrow.

The financial evidence is company-wide rather than i5-specific, which limits how strongly it can support the student's claims about the launch’s impact.

The supporting-document list and bibliography are not presented with complete consistency.
