METHODICAL TOOLS FOR ANALYSING AND EVALUATING THE EFFECTIVENESS OF DIGITALISATION OF BUSINESS PROCESSES

The article systemises methodical instruments for evaluating efficiency of measures of digitalisation of business processes of enterprise. A schematic diagram of a general algorithm for evaluating the effectiveness of measures to digitalise the business process of enterprises has been developed. It is determined that assessing the degree of effectiveness of measures to digitalise the business processes of enterprise will also indirectly create conditions for identifying bottlenecks, based on which the management of enterprise will be able to make operational management decisions to optimise the business process through its digital development. It is substantiated that the assessment of business processes and their digitalisation should lie within the functional responsibilities of a certain entity; for this purpose, it is proposed to establish committees at the enterprise to assess the efficiency and digitalisation of business processes. In addition to formulating proposals for eliminating bottlenecks and directions and methods of digitising the company's business processes, the functional responsibilities of the Business Process Efficiency and Digitalisation Committee include the function of assessing the efficiency of an already digitised business process. For this purpose, the Committee develops analytical tools using established business process evaluation methods adapted to the evaluation of a digitised business process, which may include the PDCA cycle, internal audit of business processes, analysis of key performance indicators, functional and cost analysis, and analysis of stakeholder requirements. Each of the proposed instruments for evaluating the effectiveness of measures to digitalise the enterprise's business processes is adapted. It is summarized that when assessing the efficiency of business processes with a view to determining the need for their digital transformation or assessing the efficiency of a digitised business process, it is advisable for an enterprise to approach this issue in a comprehensive manner, namely, to develop clear policies and procedures by establishing and regulating the activities of the committee for assessing the efficiency of the enterprise's business processes by delegating to it a responsible person from each unit for managing business processes that create value or participate in this process.

Methodology of evaluating finished goods warehouse performance through lean methods

This paper considers the problem of evaluating the effectiveness of the finished goods warehouse of a manufacturing company, in which a modified TPM method - Total Productive Management (TPM2) - was applied to improve productivity. A multi-stage methodology was proposed, including a decision to modify the system, determination of the scope of changes, monitoring the results obtained and a multi-criteria evaluation of the changes made. The decision to make modifications to the existing system was motivated by the lower-than-expected quality of customer service (frequent delivery delays). With regard to the transport department, lean flow pillar activities were focused on analysing losses (muda) in warehouse processes (product loading and package unloading). The purpose of these activities was to minimise interruptions in warehouse processes (product loading and package unloading). "The steps for solving the problem" methodology based on Deming's PDCA cycle was used to solve the problem. The analysis covered, among other things, the information flow processes between production planning and the customer service department, the planning processes of the dispatcher, the efficiency of the loading processes, and the causes of interruptions in warehouse operations. The analyses employed the chronometry of selected works, the 5W + 1H method and the Pareto method. By using the 5S method and some characteristics of the SMED method, the organisation of loading work was decisively changed (shunting yard changes, appropriate buffers for transport equipment). The changes introduced in the system were monitored for several months. Appropriately defined OEE indicators were used to assess the behaviour of the system after the changes. The indicators consider the use of available warehouse time, the efficiency of the loading process and the quality of the tasks performed. The results that can be achieved are presented using the specific example of the finished goods warehouse of a manufacturing company in the FMCG sector.

Interventional therapy of pulmonary embolism - update

Several catheter-based systems have been developed for interventional recanalization of pulmonary embolism. These include local ultrasound assisted thrombolysis (EKOS), in-toto-thrombectomy via retriever and aspiration system (FlowTriever) and the Indigo mechanical aspiration system. Safety and efficacy in the removal of thrombus have been demonstrated for all systems. Interventional recanalization strategies for high- and intermediate-high risk pulmonary embolism are potentially more effective in the removal of thrombus and restoration of right heart function than systemic thrombolysis with a lower risk of major bleeding complications. Preliminary data from registries and observational studies are very promising whereas the evidence for systemic thrombolysis treatment in high and intermediate-high risk pulmonary embolism is low. Randomized controlled clinical trials are currently performed comparing catheter based interventional therapies to systemic thrombolysis for the treatment of intermediate-high risk pulmonary embolisms. Primary outcome measurements include mortality, hemodynamic collapse, and major bleedings. Results are expected in 2025. The introduction of interventional therapies for pulmonary embolism was accompanied by an increased awareness of the complexity of pulmonary embolism management. The need for specialized interdisciplinary pulmonary embolism response teams (PERT-teams) and a well-structured approach including a PDCA cycle was recognized.

Work Standardization in Lean Manufacturing for Improvement of Production Line Performance in SME

Lean manufacturing is a management philosophy and production system that provides all humanly conceived soft technology to remove waste in any production line. One of the requirements of lean is work standardization. Work standards impose a 'rule of law' in a production line by restricting operators to how long they should work on a single unit. The standards consist of the standard workflow, standard work time, and standard quantity that must be adhered to to meet the customers' demands. The main objectives of this study were to improve the performance of a production line, say SW660 x 600, in terms of weekly output, lead time, and work-in-process (WIP). By applying certain lean elements to the production line, this work indeed improved the performance of the production line. In this work, 5S, PDCA cycle, SPC, and VSM tools were used together to solve the production line problems systematically. It was noticed that the low weekly output and long cycle time at each workstation resulted in delays in the delivery of products to customers. The study managed to increase the weekly output from 61.75 per week to 128.75, an improvement of more than 108.50 percent. Next, in terms of lead time, with the help of a simulation exercise, this work also managed to reduce the lead time from 5 to 1 hour, a reduction of 80 percent. Lastly, the WIP also recorded a reduction from an average of 17 to 9 units weekly, which was an improvement of 47 percent on the weekly WIP. Therefore, this work showed that with the introduction of work standards on the production line, the organization could meet the customers' demands and deliver on time as promised. The study can also be used in other production lines of this and other organizations to help improve their production line performance in the long run.
