This project plan investigates the impact of word-of-mouth (WOM) in the fast food industry, focusing on Krispy Kream UK. The research aims to determine the positive and negative consequences of WOM as a marketing tool. The objectives include understanding how WOM functions as a promotional tool and its effects on the fast food sector. The project addresses the problem of fast food companies relying on WOM for promotion, which is influenced by consumer attitudes and perceptions. The literature review highlights WOM's role in Krispy Kream's promotion and its implications, both positive (satisfaction leading to free promotion) and negative (negative experiences leading to discouraging potential consumers). Data collection relies on secondary sources, including books, journals, and online articles. The conclusion emphasizes WOM's importance for low-budget fast food marketing and its potential positive and negative impacts on businesses. The assessment uses a Gantt chart to track project activities. References include relevant academic sources.
