Hallo jplhix, the fountain model is basically an improvement on the waterfall model. There are basically the same steps to observe as in the waterfall model (listed in the additional sources section), the main difference is that in the fountain model you can still take a step back to a previous point on the list (taking into account that sequences may always contain cycles). Obvious advantages because of this differences are: 1. You don't have to freeze the requirements too soon. 2. There are more interactions between design and requirements steps. 3. The coding can be started earlier. I hope this answer is helpfull. If you require additional informaiton or some part of the answer is not clear enough, don't hesitate to request a clarification. voyager-ga Additional Sources Illustration of the waterfall model http://www.csse.monash.edu.au/~jonmc/CSE2305/Topics/07.13.SWEng1/html/text.html#traditional_waterfall_model Illustration of the fountain model http://www-staff.mcs.uts.edu.au/~cotar/moses.fountain.html ERUPT: pragmatic software development lifecycle http://members.dodo.net.au/~void/old/erupt.htm QuickStudy: System Development Life Cycle http://www.computerworld.com/developmenttopics/development/story/0,10801,71151,00.html Search Strategy waterfall fountain model ://www.google.com/search?hl=en&lr=&ie=ISO-8859-1&q=waterfall+fountain+model waterfall fountain comparison object ://www.google.com/search?q=waterfall+fountain+comparison++object&hl=en&lr=&ie=UTF-8&start=0&sa=N
