A Software Development Methodology for Research and Prototyping in   Financial Markets
  The objective of this paper is to develop a standardized methodology for software development in the very unique industry and culture of financial markets. The prototyping process we present allows the development team to deliver for review and comment intermediate-level models based upon clearly defined customer requirements. This spreadsheet development methodology is presented within a larger business context, that of trading system development, the subject of an upcoming book by the authors of this paper.
