The document discusses several constraints that will affect a marketing project for Irn-Bru. It notes that the project has a 3 week timeframe, so planning and creating mockups is important to meet deadlines. Resources like a camera, lighting, and Photoshop software will need to be sourced from within the college. The marketing approach will need to suit the target audience and brand image of Irn-Bru without causing harm or offense. Restraints from organizations like the Advertising Standards Authority around copyright, misleading advertising, harm and offense, and protecting children will also need to be considered.
