With the development of the Internet and the need for key information, information systems are becoming an indispensable part of organizations in the 21st century, and thus their strategic planning and construction is a far-reaching process. In practice so far, it has been observed that the information system helps the organization's employees in almost all business segments, from basic and specific functions, auxiliary, management functions to analysis and improvement functions, i.e. reorganization. Organizations need to build different information systems with different functionalities, and their construction and development often require an individual approach. The construction of an information system requires significant financial, time and technical resources, so it is the goal of organizations to carry out strategic planning in a systematic and high-quality way. In order for the information system to achieve its full potential and purpose, it is necessary to build it according to the already established guidelines of information experts. Various spheres of information and other sciences are involved in this process, and several of the same patterns and approaches that all organizations follow have been observed. Throughout history, models and methods have been developed, and their selection and implementation depends on the criteria chosen by the organization. Different models are emerging in the IT sphere, some of which are derivatives of previous models, and represent a completely new approach. Despite dozens of models that appear in practice, it is essential to choose the optimal one in order to achieve the full potential of the information system. The methods provide insight into the tools used when building IS and are more complex. The selection criteria listed in this paper can serve organizations when choosing a suitable model and method, but organizations can also independently determine the selection criteria.
