Role and Application of OMG Notations in IT: Analysis and Survey on the Effectiveness of Business Notations Among IT Companies in Poland

This study analyzes OMG (Object Management Group) notations, their capabilities, and potential drawbacks. It includes a literature review and a survey focused on the purpose of using OMG models in the IT sector. Conducted via CAWI (Computer Assisted Web Interview) with 160 respondents from Polish IT companies, the survey aimed to identify which OMG notations are used, their practical applications, creation sequences, and the impact of job roles. The results confirmed the objective of validating the purposeful use of various notations. The survey established relationships and justified the use of specific models by Polish IT professionals with different job profiles. It highlighted the diverse perspectives needed in software development, depending on the role within the project. The survey also identified the most commonly used platforms for designing models with OMG notations and revealed that there is no universal modeling tool suitable for all stages of the process.
