The purpose of the research discussed in this paper is to identify the issues that need to be considered when endusers develop their own applications. A case study was conducted with a semi government department, which explored the reasons why end-users developed their own applications, the advantages this development brought to the organisation and the problems that could result. Some of these problems include support, maintenance, design difficulties, management and the lack of control and documentation. Possible solutions for these issues are also briefly discussed.
