Many organizations develop their information systems without the use of any information systems development methodology. However, even when organizations identify the need for the use of such methodologies, it is not always obvious which to use, or whether a blended combination might be appropriate. Further, in using either stand-alone or blended information systems development methodologies in practice, a number of difficulties are encountered. This paper discusses the use of an information systems development methodology which consisted of a blend of other methodologies in a real-world situation (a large telecommunications company) where no formal methodology had been used previously. A number of difficulties arose in practice, some of which were not anticipated. Examples are given of the types of difficulty encountered, and these fell into three broad categories: those related to the deficiencies in the design techniques and tools themselves; those related to implementing the system from the design; and those related to the particular environment.
