Abstract:
Effective decision-making is essential for enhancing operational efficiency and
performance in the dynamic supermarket sector in Sri Lanka's supermarket
industry. The impact of Data-Driven Decision Support Systems (DDSS) presents
a valuable opportunity to improve the effectiveness of managerial decisionmaking
processes. Despite the proven advantages of Decision Support Systems
(DSS) in streamlining decisions and increasing responsiveness, implementation
remains limited across many supermarkets. This study investigates the role and
effectiveness of DSS components, including the database, database management
system, data directory, and query facility, in supporting decision-making among
middle- and top-level managers in supermarket operations. Using a quantitative
research approach, we collected data using a structured questionnaire with 37
items, each measured on a five-point Likert scale. A conceptual framework was
developed to analyse the relationships between key DSS components
(independent variables) and managerial decision-making effectiveness
(dependent variable). Responses were obtained through simple random samples
from selected supermarket branch managers. Structural Equation Modelling
(SEM) was employed to test the research hypotheses and validate the conceptual
model. Findings reveal that DSS implementation significantly enhances
operational decision-making, particularly at the branch management level. The
results underscore the positive impact of well-integrated DSS components in
improving decision quality, operational efficiency, and overall performance in
the supermarket sector. This research fills a critical gap by identifying specific
DSS systems that contribute most effectively to supermarket managerial
decision-making. Future studies are recommended to expand the scope by
incorporating longitudinal data and exploring sector-wide technological
adoption barriers. The insights generated are valuable to supermarket managers, policymakers, and technology developers aiming to optimise
decision-making processes and drive innovation in supermarket operations.
