The rationale of the study is below
The use of sales promotion strategies, a wide range of tactics and techniques designed to stimulate customer interest and increase sales of products or services, has become increasingly important for organizations as they seek to improve their performance in today’s highly competitive business environment (Kotler et al., 2017). The proposed study seeks to explore the effect of sales promotion strategies on the overall performance of Nigeria Breweries Limited (NBL), a leading brewing company in Nigeria’s beverage industry. The research is of great significance due to the ever-growing competitive landscape of the beverage industry, where companies compete on several fronts, including product quality, branding, and promotional activities. It aims to fill an existing knowledge gap by evaluating the effectiveness of sales promotion strategies and their ethical implications, consequently providing actionable insights on adopting innovative tactics and training programs.
From a theoretical perspective, this research will draw on marketing theories. The consumer behavior theory, according to Hanaysha (2016), posits that individuals and groups make consumption decisions based on their needs, preferences, and the perceived values of available options. The stimulus-response theory, on the other hand, contends that consumers will react to a promotional stimulus, such as discounts or freebies if the perceived results align with their needs and elicited affect. Finally, the hierarchy of effects model explores how promotional campaigns can progress consumers through various stages, from awareness to action. This study will also be guided by the resource-based view (RBV) of the firm, which posits that a company’s resources and capabilities are the primary determinants of its competitive advantage and performance (Barney, 1991). According to the RBV, a company can gain a sustainable competitive advantage by leveraging its unique resources and capabilities to create value for its customers and stakeholders. These theories will offer invaluable frameworks to analyze the effectiveness of various sales promotion strategies adopted by NBL. In the organizational context, Nigeria Breweries Limited presents a suitable case study, as it operates in a highly competitive industry with numerous local and global competitors. Assessing the organization’s promotional activities could uncover opportunities to refine, innovate and enhance their sales and marketing effectiveness. Additionally, NBL has a responsibility to uphold ethical and sustainable practices, which adds another layer of relevance to this research. The potential interest in this study is wide-ranging, as it could be beneficial for marketing professionals, educators, and policymakers. Marketing professionals may apply the study’s findings to their strategies to drive organizational performance, while educators can incorporate the research in their curriculum to better equip future marketing practitioners. Policymakers, on the other hand, may use the study to understand the industry’s best practices and establish suitable legal and ethical frameworks. The personal interest in this study stems from the desire to contribute to the advancement of marketing knowledge, specifically in the context of the Nigerian brewing industry, and enhance my understanding of promotional strategies’ effectiveness and ethical implications. By conducting this research, I hope to offer valuable insights that promote sustainable success and competitive advantage for organizations such as Nigeria Breweries Limited.
