Dynamic System Development Method (DSDM) Dynamic System Development Method is another approach to system development‚ which‚ as the name suggests‚ develops the system dynamically. This methodology is independent of tools‚ in that it can be used with both structured analysis and design approach or object-oriented approach. The Dynamic System Development Method (DSDM) is dynamic as it is a Rapid Application Development method that uses incremental prototyping. This method is particularly useful for

about the nature of population. It is because of this that these methods are sometimes referred to as the distribution free methods. Most of these methods‚ however‚ are based upon the weaker assumptions that observations are independent and that the variable under study is continuous with approximately symmetrical distribution. In addition to this‚ these methods do not require measurements as strong as that required by parametric methods. Most of the non-parametric tests are applicable to data measured
