Abstract
Working processes in the technological sewing process are performed on machine systems characterized by machine-manual work, where the worker and the machine work simultaneously. Such a work system requires a great deal of responsibility in terms of quality, quantity, and the accurate and timely execution of tasks, which requires the quick and accurate response and extremely good psychomotor and visual skills of workers. This paper presents the process of determining the working method and normal times for the technological operation of runstitching women’s blouse collars, which includes the design of an ergonomically designed workplace, the selection and technical equipment of the universal sewing machine and the determination of the optimal work method and normal times using the Methods-Time Measurement (MTM) system. The research results obtained indicate that the technical equipment of a universal sewing machine has a significant impact on the structure of the technological sewing operation and the working method, i.e. the number of auxiliary manual technological suboperations. Improving technical equipment, i.e. increasing the number of automated functions used on a universal sewing machine, reduces the number of auxiliary manual suboperations, reduces the time required to perform the technological operation and increases work productivity.

For the successful business of the garment industry, modern production processes are organized according to the Quick Response (QR) strategy, the task of which is to respond quickly to market demand, and the Just-in-Time (JIT) technology strategy aimed at the prudent planning of production time
Summary
The garment industry is labour-intensive and represents the final stage of textile processing. According to the organization of the work process, technological sewing operations are considered an assembly (piece) type of work process with a linear method of workplace installation At their workplaces, workers perform technological operations of similar characteristics, leading to a higher degree of utilization of machines and devices, the improved transport of materials and workpieces through the production line, the reduction of production times, and production cycles. An ergonomic and functionally designed workplace and the determination of optimal work methods with corresponding time norms are required for the successful performance of the technological operation This will facilitate the favourable structure of the technological operation, with the increased use of machines and increased hourly production, while reducing the psychophysical workload on workers, increasing productivity and production quality and reducing production costs [9, 10]. Working method analysis and the determination of time norms of the technological operation of runstitching women’s blouse collars were performed using the MTM system
