Studies in Commerce, Govt. Arts College (Autonomous) Chitradurga ABSTRACT ARTICLE HISTORY Effective supply chain management (SCM) is increasingly critical to the competitiveness and operational efficiency of retail enterprises. This study examines how SCM practices procurement processes, inventory management, supplier collaboration, logistics & distribution, and information systems influence operational efficiency in organized retail in Karnataka. Adopting a mixed-methods approach, the study draws on a structured survey of 400 store managers/operations staff across five Karnataka cities (Bengaluru, Mysuru, Mangaluru, Hubli– Dharwad, Belagavi) and 15 in-depth interviews with supplychain managers and suppliers. Quantitative analysis uses descriptive statistics, ANOVA, and multiple regression; qualitative data were analysed by thematic coding. Results indicate that improved inventory management (higher inventory turnover, lower stockouts), integrated IT systems (real-time inventory visibility), and closer supplier collaboration (joint planning, vendor-managed inventory pilots) significantly predict higher operational efficiency (measured via order fulfilment rate, reduced lead time, and lower supply-chain cost per sale). Logistics infrastructure and state-level initiatives have supported improvements, but fragmentation in last-mile distribution and supplier heterogeneity remain constraints. The model explains about 52% of variance in operational efficiency (R² ≈ 0.52). Practical implications include prioritising investments in inventory analytics, supplier capacity-building, and regional consolidation centres; policy implications suggest targeted Submitted/Received: 01 Oct 2025 First Revised: 27 Oct 2025 Accepted: 19 Nov 2025 Publication Date: 19 Dec 2025 KEYWORDS: supply chain management, operational efficiency, organized retail, Karnataka.

Retail firms increasingly recognize that competitive advantage is no longer derived solely from location, pricing, or promotional strategies, but from the efficiency and responsiveness of their supply chains. Supply Chain Management (SCM) has therefore emerged as a strategic function that integrates procurement, production, warehousing, transportation, and information flows to ensure the right products reach the right place at the right time and cost. Within organized retail, SCM practices play a decisive role in shaping operational efficiency. Strategic sourcing decisions influence input costs and supplier reliability, while inventory management systems determine stock availability and turnover rates. Similarly, logistics and distribution networks—particularly last-mile delivery— directly affect order fulfilment, lead times, and customer satisfaction. Inefficiencies at any stage of the supply chain can result in stockouts, excess inventory, higher operational costs, and diminished consumer trust. Consequently, retailers increasingly invest in advanced SCM practices such as automated replenishment, supplier collaboration, third-party logistics (3PL) partnerships, and information technology–enabled real-time inventory visibility. In the Indian context, the rapid growth of organized retail has intensified the need for efficient and resilient supply chains. Karnataka, with Bengaluru as a major commercial hub and several fast-growing secondary cities, presents a diverse and dynamic retail environment. Variations in infrastructure quality, supplier networks, and logistics capabilities across urban centres pose both opportunities and challenges for retail supply chains. Despite the strategic importance of SCM, empirical studies that systematically link specific SCM practices to operational efficiency at the state level remain limited. Against this backdrop, the present study analyses which SCM practices meaningfully enhance operational efficiency in retail enterprises operating in Karnataka’s urban markets. By combining quantitative measurement of SCM outcomes with qualitative insights from retail managers and suppliers, the study aims to generate evidence-based and context-specific recommendations that can support retailers in improving performance and assist policymakers in strengthening the retail supply-chain ecosystem in the state. Background: Government Data & Present Situation (India & Karnataka) India’s retail sector is one of the world’s largest and continues to grow rapidly, with the overall market valued at around ₹82 lakh crore (₹8.2 trillion) in 2024, up from about ₹35 lakh crore in 2014, reflecting nearly 9% annual growth over the last decade. Organized retail comprising supermarkets, hypermarkets, and modern retail chains is expanding fast and is projected to reach around ₹19.7 lakh crore (₹19.7 trillion) by 2030, capturing an increasing share of total retail sales as consumers shift toward formal retail formats. As of FY25, India also has the third-highest number of online retail shoppers globally, highlighting the growing integration of digital commerce with brick-and-mortar retail. National policy efforts aim to strengthen logistics and supply chains to support this expansion. Initiatives such as state performance assessments under the National Logistics Policy and related frameworks seek to reduce logistics costs, enhance connectivity, and improve efficiency across states. Karnataka, in particular, has undertaken active logistics and industrial measures, though challenges with last-mile connectivity and uneven infrastructure in some regions still affect retail supply chains at the operational level. From a macroeconomic perspective, logistics costs in India remain a significant burden estimated at around 8% of GDP prompting retailers to optimize distribution networks, inventory strategies, and transportation modes to maintain competitiveness. Within Karnataka, organized retail growth is prominent, especially in Bengaluru, which is emerging as a major retail and commercial hub with retail stock expected to expand significantly through 2030. Secondary cities Manuscript on the Sustainable Economics, Finance and Management Vol 2, Issue 7 (2025) | ISSN 3064-8645 - 114 - such as Mysuru, Mangaluru, Hubli-Dharwad, and Belagavi also show growing organized retail activity. State economic and trade reports consistently highlight the expansion of the trade and services sector, underscoring the strategic importance of efficient supply chain management for sustaining retail growth across Karnataka.

Research gap Existing literature includes global SCM frameworks and some national-level studies on retail supply chains, but there is limited empirical evidence linking specific SCM practices to quantifiable operational-efficiency outcomes at a state level in India. In particular, Karnataka’s mixed urban profile (a major metro plus several growing secondary cities) needs focused study on how SCM practices and local logistics infrastructure interact to produce store-level efficiency. Objectives 1. To evaluate the adoption level of key SCM practices (inventory management, supplier collaboration, information systems, logistics choices) in organized retail enterprises in Karnataka. 2. To measure operational efficiency outcomes at store/chain level (order fulfilment rate, lead time, stockout frequency, supply-chain cost per sale). 3. To test which SCM practices significantly predict operational efficiency. 4. To provide retailer-level and policy recommendations to improve SCM-driven operational efficiency in Karnataka. Methodology The study follows a mixed-methods design, combining a cross-sectional quantitative survey with qualitative interviews to capture both numerical evidence and managerial insights on supply chain practices. Primary data were collected from 400 supply-chain, operations, and store managers across organized retail outlets in five Karnataka cities Bengaluru, Mysuru, Mangaluru, Hubli–Dharwad, and Belagavi. In addition, 15 semistructured interviews were conducted with supply-chain managers, logistics providers, and suppliers. A structured questionnaire using Likert scales and operational performance indicators was employed, with acceptable reliability. Data were analysed using descriptive statistics, ANOVA, multiple regression, and thematic analysis. Fieldwork was conducted in 2025 with ethical safeguards ensured. The statistical tables below are based on the researcher’s primary data collection (survey of N = 400, 2025) unless a secondary government/industry source is specified under the table.

IT visibility, automated replenishment, and supplier collaboration are statistically significant and substantive predictors of operational efficiency. VMI adoption shows positive but not statistically significant effect in this sample (p = .103), possibly due to low adoption levels. The model explains 52% of variance in OE index. Findings 1. Role of IT and automation: Retail enterprises with real-time inventory visibility and automated replenishment systems show higher operational efficiency. These technologies reduce stockouts, improve inventory turnover, and support faster and more accurate decision-making. 2. Importance of supplier collaboration: Joint planning, information sharing, and collaborative forecasting with suppliers contribute positively to order fulfilment rates and help minimize demand– supply mismatches. 3. Effect of third-party logistics (3PL): Use of 3PL providers improves last-mile delivery performance, especially in urban areas, but the benefits vary due to differences in service quality, coverage, and technological capabilities. 4. City-level differences in efficiency: Retail operations in Bengaluru demonstrate higher operational efficiency compared to secondary cities, largely due to better infrastructure, stronger logistics networks, and greater adoption of digital SCM practices. 5. Limited adoption of VMI: Vendor-Managed Inventory practices are present mainly as pilot initiatives. Although they show potential to reduce stockouts and improve replenishment, wider adoption is constrained by trust and data-sharing issues. 6. Influence of macro-level constraints: High logistics costs and fragmented logistics infrastructure continue to affect supply chain decisions, shaping sourcing, distribution, and inventory strategies of retail enterprises in Karnataka. Recommendations (Retailers & Policy) For Retailers 1. Invest in integrated inventory-management information systems that provide real-time visibility across the supply chain to improve replenishment accuracy and reduce stockouts. 2. Introduce automated replenishment in a phased manner, supported by reliable demand-forecasting models, to increase inventory turnover and control holding costs. Manuscript on the Sustainable Economics, Finance and Management Vol 2, Issue 7 (2025) | ISSN 3064-8645 - 118 - 3. Strengthen supplier collaboration through joint planning, information sharing, and regular performance reviews, and pilot Vendor-Managed Inventory (VMI) with dependable suppliers. 4. Optimize last-mile delivery by adopting hub-and-spoke or micro-fulfilment centre models and by standardizing service-level agreements with third-party logistics providers. 5. Build human capacity by training store and supply-chain staff in data-driven decision-making, inventory analytics, and exception management. For Policymakers / State (Karnataka) 1. Develop state-level logistics hubs and cold-chain clusters to reduce lead times and improve supply reliability, especially for perishable retail categories. 2. Provide incentives and financial support under MSME and digitalization schemes to encourage adoption of inventory and order-management systems among small retailers and suppliers. 3. Improve last-mile connectivity and streamline regulatory and approval processes to reduce operational delays and enhance overall logistics efficiency in line with national benchmarks. Conclusion The study demonstrates that effective supply chain management practices significantly enhance operational efficiency in organized retail enterprises in Karnataka. Key practices such as real-time inventory visibility, automated replenishment, and supplier collaboration consistently improve order fulfilment, reduce stockouts, and optimize inventory turnover. While third-party logistics and Vendor-Managed Inventory show potential, their impact is currently limited by adoption gaps and service variability. City-level differences indicate that infrastructure and technology adoption play a crucial role in performance outcomes. Macro-level constraints, including high logistics costs and fragmented networks, continue to influence retail strategies. Targeted investments by retailers and supportive state policies can collectively strengthen supply chains, reduce operational inefficiencies, and foster sustainable growth in Karnataka’s retail sector.
