The subject of this paper is the consideration of information systems development with an emphasis on the role of business and systems analysis. Additionally, the paper includes two examples of business and systems analysis in practice. The motivation for addressing this topic and providing examples of business and systems analysis is the fact that the available literature describes the development of information system sin theory with minor variations depending on the author and the year of publication. However, it is difficult to find an example that connects this theory with practice. It is especially difficult to find an example of a software solution that has been actually developed, is actively used, and, moreover, has some part of it publicly available. Therefore, one of the goals of this work is to provide general benefit to the academic community, primarily to students of business and technical studies. In line with the above, the aim of this paper is also to study, clarify, and demonstrate the process of developing a new software solution for a client from the public sector, specifically a regional government unit, with an emphasis on the role of business and systems analysis in the entire development process. In another example, the goal is to show how the improvement of an existing software solution looks to meet new legal standards and implement them with existing public sector users. The software solutions presented in this paper were developed, implemented, and are owned by the company Libusoft Cicom d.o.o. from Zagreb. The two examples mentioned provide a closer explanation of the significant and hard-to-replace role of business and systems analysts in the development of business information systems. Currently, in the job market among IT professions, business and systems analysts are perhaps the most sought after due to the combination of knowledge and skills they must possess. This includes domain knowledge in the area for which the software is being developed and technical knowledge to translate the business requirements of the users to the development engineers. The role of business and systems analysts varies from organization to organization, and these two roles are often combined into one person, who is required to understand the business requirements of the user and create a development analysis document that serves as the basis for the work of development programmers. Due to the complexity and need for communication and understanding of the end user, the role of analysts will hardly be fully replaced by any tool or artificial intelligence in the near future.
