Lean production tools to improve the efficiency of sales of construction materials

Abstract

Background: In modern conditions, the concept of Lean has proven its effectiveness both in the production sphere and in the sphere of services, and public administration. In addition, this philosophy is becoming popular in everyday life. An important type of activity of any manufacturing enterprise is the sale of products. The problems of organizing the work of the sales department of an enterprise for the production of asphalt-concrete mixtures are investigated, and the possibilities of using lean technologies are considered. Methods: With the help of the "cross-functional map" tool, the sales process is analyzed in terms of individual operations and responsible persons, indicating the execution time of each stage. Results: All operations that make up the process are divided into actions that create value for the product consumer; actions that do not provide added value, but cannot be abandoned, and actions that are unproductive losses, according to the Lean approach. Such operations were waiting for confirmation of payment and waiting for confirmation from the download. By eliminating unproductive waste through improved communication tools, actual manager involvement was reduced and overall process time was reduced by 30 minutes within one process. The implementation of the "qualification matrix" tool made it possible to determine the level of real skills and knowledge of the staff and identified weak points. The management organized training to improve the qualifications of employees. According to a preliminary assessment, this will ensure the interchangeability of personnel and free up 2 employees who will be involved in other processes. The implemented 5S system made it possible to reduce the time to search for the necessary information by 20 minutes. within 1 order. Conclusions: The use of Lean (lean production) tools allows you to achieve: cost reduction, product quality assurance, management process transparency, increase consumer satisfaction with the company's products, increase the involvement of the company's personnel and strengthen their motivation, reducing the loss of resources.
