An inexperienced user can face various difficulties while developing an individual information system. In fact, these difficulties can be provoked by various factors, but it is obvious that the main reason is the lack of practical experience of inexperienced users, though their educational level, qualification and individual abilities are also very important. Nevertheless, in spite of individual peculiarities, it is possible to single some common problems and difficulties users can face while developing their individual information systems.
First of all, one of the major problem inexperienced users can have is the problem of a low productivity. Basically, this problem has been recognized in terms of software crisis, as indicated by the development of backlog and maintenance problems. In fact, the essence of this problem is the rapid development of information technologies and software, which prevent inexperienced users from the application of the most recent and advanced software and applications (Andrew, 2003). As a result, the information system developed by an inexperienced user turn out to be out-of-date even though it has been created recently. At the same time, this problem can be provoked by the increasing cost of software development and poor productivity improvements that is natural for inexperienced users.


Another serious problem inexperienced users can face while developing their information system is a large number of outright failures. In fact, this problem is often caused economic miscalculations of users because they cannot define exactly how much money they need to spend on their individual information system. As a result, often when they attempt to save costs, they buy applications and software of a low quality that naturally affects the entire information system which also proves to be of a low quality. At the same time, the use of products of the low quality leads to numerous failures of the individual information system.
Also, it is possible to mention the problem of the poor alignment of information system and users’ needs. What is meant here is the fact that often inexperienced users launch developing their individual information system without clear understanding of what information system they actually want to create. For instance, many users spend a lot of time and money on recording, searching, refining and analyzing information, but they cannot get the information they actually need (Behzad, 2003). In this respect, it should be said that the information system development is challenged by the dynamic nature of information technologies which keep progressing, while software grows to be more and more complex that leads to ongoing problems of inexperienced users in the development of their individual information systems.
Nevertheless, the use of appropriate case tools can be helpful to inexperienced users, though it does not resolve all the difficulties and problems they face while developing their information system. For instance, UML 2.1, the Unified Modeling Language, is a widely used standard in software industry which is applied for modeling software (Behzad, 2003). Basically, it can help users to visualize, communicate and implement their design saving their time and ensuring a relatively good quality, though it should be said that such design will be rather standardized than original.
Thus, in conclusion, it is possible to stress numerous problems and difficulties inexperienced users can face while developing their information system. However, they can use case tools to partially surmount these difficulties. In fact, through practice and efforts, users can overcome their problems in the information system development.
