Courtney Hill is writing a product investigation report for graphics class comparing Heinz's glass ketchup bottle to their plastic bottle. She contacts Heinz requesting information on performance analysis, materials used, manufacturing process, and quality control for both bottles. Heinz provides details on the form, function, user requirements, performance requirements, materials used, scale of production, and cost of each bottle. Key differences noted are the glass bottle looks more expensive but is less user-friendly, while the plastic bottle is easier to use but less aesthetically pleasing. Both bottles effectively contain and dispense ketchup through proven mass production methods.
