What are the components typically required for DECA's written event submissions?

The correct answer highlights the essential components typical for DECA's written event submissions, which generally include a business proposal, marketing plan, or research paper, accompanied by an executive summary. Submissions in DECA competitions aim to evaluate participants' understanding and application of business principles, requiring them to present coherent and structured documents that outline their strategies or findings clearly.

The executive summary serves as a critical component, summarizing the overall content and main points of the submission to give judges a quick overview of the project’s objectives, methodology, and conclusions. Including such detailed and specific elements demonstrates a comprehensive grasp of the subject matter and adheres to the competitive standards set by DECA.

In contrast to the other options, a resume and cover letter focus more on individual qualifications rather than the project itself. Financial statements and future forecasts may be relevant in certain contexts but do not encompass the broader array of documents typically required for written events. Marketing brochures and social media posts could be part of a project presentation but lack the depth and formal structure necessary for DECA's written submissions.
