The process of describing human activities in procedures has been used since the beginning of the 20th century. However, it is increasingly evident that procedures understood as sets of orders and prohibitions can be counter-productive because they do not allow the proper use of employees' knowledge and experience. Therefore, it is postulated that guidelines for practice should be co-developed by employees from the 'sharp end' of the organization, but there are no simple methods that can achieve this aim. In the present work, we propose a procedure based on sticky notes, inspired by how information technology teams function. We present a description of the original sticky notes method (SNM) and demonstrate its application in the railway sector. As a result of the workshops conducted with the participation of experts, we gained knowledge about practices that were not included in the documentation, but that could significantly improve the process under research. The primary purpose of the SNM is to ensure the involvement of employees in the process of creating guidelines for practice. This method is particularly useful for describing linear processes in which activities can be arranged chronologically.

Turbine engines are currently one of the most important and expensive aircraft components. Both for economic and safety reasons, high engine reliability is required. Therefore, sophisticated methods are needed to determine their current condition. Diagnostics of turbine engines allow for the detection of faults before they lead to damage. The article presents methods and results of vibroacoustic diagnostics of a miniature GTM400 jet engine adapted to kerosene and hydrogen fuel supply. During thermal and vibroacoustic tests of engine parameters powered by hydrogen fuel supply, the engine seized up in the initial start-up phase due to improper control and rapid thermal changes in the gas line. The cause of the undesirable technical condition of the engine was a significantly higher temperature of gases (exhaust gases) affecting the working elements of the engine (turbine shaft, rotor, and blades), which consequently led to engine damage. This phenomenon and the results obtained from the unexpected technical condition constitute a valuable premise for considering the issue of proper operation of the turbojet engine during fuel changes, especially following current trends related to the decarbonization of the aviation sector. The obtained research results and the resulting observations and conclusions make it necessary to perform technical analyses and pre-implementation tests each time before allowing the use of a conventional engine if it undergoes the process of reconstruction in terms of using a new fuel (especially if its technical parameters are different from the originally used one). The presented method of conducting tests allows for a detailed determination of the causes of damage to the cooperating elements of the engine structure under the influence of changes in operating parameters.
