In this study, the improvement of the IP system, which is the core infrastructure of the MRO project, and its effect were analyzed. Systematic problems and problems that are not competitive in the actual operating environment were systematically derived, and based on this, the most suitable method for target system development was found and improved. And the data of the improved system was analyzed and the effect was verified through empirical analysis of the system improvement effect through the user questionnaire. As a result of the study, the item with the highest improvement effect was convenience, which increased by 12.43 points. Then it increased by 10.25 points in terms of features. In particular, you will notice a significant improvement in speed by 30-50%. This is because the empirical analysis results are more objective and realistic than other conceptual models. Also, from the practical point of view, based on the results of the empirical analysis, corporate management can more effectively promote the intellectual property system, which is expected to contribute to the enhancement of corporate competitiveness.

Companies incur costs in the care of indirect equipment used in production, that is, in maintenance, repair, and operation (MRO) of equipment. However, MRO can waste manpower and time, so that many companies engage MRO companies as substitutes. In the past, MRO substitution companies have conferred advantages that allowed companies to cut prices. As a result of those savings, companies were more likely to purchase high value items. But as prices drop and companies have more varied requests, MRO substitution companies must find new strategies to stay competitive. This research is an effort to escape the exhaustive adherence to price-cutting methods, and instead find ways to maintain continuous relations with customers through price benefits and services. First, product groups must adhere to purchase deadlines. Although logistics centers originally operated and managed deliveries, some items were too large to be delivered. To solve the problem, groups should contract with delivery companies to assure smooth delivery despite problems. Also, delivery companies could supplement computing processes by delivering original documents such as quality certificates between company and customer. Second, companies should communicate with customers regarding the maintenance of current prices, provision of additional service if current prices change, and to find problems and improvements regarding current operations that need to be addressed. The research shows that MRO purchasing companies should focus on customer needs rather than only on price if they are to satisfy customers and accomplish continuous growth.

In their efforts to compete and grow, companies try to reduce prime costs incurred by their purchasing groups, costs that may be more than 60% of sales. The recent financial crisis and the global economic depression have made it difficult to increase sales, so competitive purchasing is essential. Purchasing-efficiency benefits can be compared with sales-increase benefits: a 5% reduction of purchasing costs has the same effect as a 25% increase in sales. Some companies are using B2B purchasing substitution companies to reduce prime costs of raw materials, subsidiary materials, MRO (maintenance, repair, operation), and consumable materials. In this research, I examine whether purchasing substitution increases purchasing satisfaction and recommend ways to enhance the competitiveness of purchasing substitution. Corporate purchasing substitution strengthens integral purchases, simplifies systems, strengthens the supply network, and enhances customer service regarding quality, deadlines, logistics, and focus. This research is an effort to show how purchasing substitution systems can work best and to discover factors that contribute to corporate satisfaction. Most important is to use highly experienced purchasing experts who can reduce unnecessary costs through integral purchases. First, knowledgable and experienced purchasers can improve bid ordering rates. They can improve corporate satisfaction by recommending products suitable for price negotiation and sharing professional knowledge about items. Second, knowledgeable agents can improve sales rates by securing strong supply networks and minimizing distribution margins. Price competitiveness is most important in purchasing well-organized substitution services to allow expansion of new sales and better long-lasting account relations.

Purpose - This study aims to provide a clue on which factors current managers and many more potential entrepreneurial applicants were required to concentrate on presenting effective research methods in the effects of purchasing companies' perception of service quality about suppliers of MRO industrial goods on the quality of relationships. Research design, data, and methodology - To accomplish the purpose of this study, we plan to conduct a research model with factors of MRO service quality as the leading variables and conduct a causal analysis using regression analysis on their influence relations. Results - In order to achieve the above purpose, it is necessary to select service quality factors suitable for the characteristics of MRO industrial goods supplier companies. And it is necessary to develop a plan for improving the relationship quality with buyer companies by understanding the sales orientation of MRO industrial goods supplier companies. Also, they develop a combined strategy capable of facilitating relationship quality by clarifying the role of rapport. Conclusions - It is expected that these results will provide strategic clues which service quality factors should be improved from the perspective of supplier companies and will provide various information on educational training sales skills of the sales staff.
