Extreme Spreadsheet Engineering (XSE) Extreme Programming (XP) was created in response to problem domains whose requirements change. Spreadsheet development is often done in conditions of intense time pressure, for example in merger and acquisition analysis. The spreadsheet development itself is often used to develop an understanding of what is being modelled and therefore change is constant. Key features of XP: 1. Customer satisfaction through frequent visibility of increments of functionality 2. Constant communication with customers to set and reset expectations, acceptance criteria, scope, priorities and schedules 3. Risk reduction from test-first development 4. Defect reduction from continuous review with fellow spreadsheet developers 5. Maintenance reduction through simplification 6. Increased productivity through focus on delivery of real needs as they are needed
