The systematic approach specifies how the product design processes should be approached systematically and specifically aims to make the most appropriate conceptual design before the objective design. In line with this goal, the systematic approach explains step by step how the conceptual design process should be done. One of these steps is the evaluation of solution variations. The basis of this step; The suitability of the desired conditions, the weighting and point system according to this suitability, and the determination of the result numerically constitute. Unlike other methods, the VDI (Verein Deutscher Ingenieure) 2225 method pro-vides a more understandable and transparent comparison of options by showing technical competence and cost status in a single diagram, S-Diagram. In this study, the step of evaluating and selecting all the options in the conceptual design before the objective design process with the VDI 2225 method was examined in detail. The elevator was used as an example. Eleva-tors consist of two parts traction and hydraulic. Traction elevators are divided into gearless and gearbox, and hydraulic elevators are divided into direct acting and indirect acting. These elevator types have different advantages and disadvantages compared to each other. For this reason, 3 different situations were determined, and the performances of the elevators were tried to be evaluated more objectively in the study. Situations: Elevators used in residences, high-speed elevators used in business centres and freight elevators that lift heavy loads were selected. All the results are shown on one S-Diagram. In this way, both situations were com-pared and the differences between them were revealed. As a result, the economic and technical performance of each elevator in each case was determined using the VDI 2225 method.
