Thus, merging their principles is the solution yet no formal solution has been proposed. Relying on previous work, ATT provides a mathematical model to act as a tailoring tool to formulate a new agile method based on experienced agile methods and the project specifications. It requires project managers to understand well the project requirements in terms of SDLC phases, and accordingly the new agile methodology is tailored. � 2009 IEEE.EnglishAgile MethodologiesAgile methodsFormal solutionProject managersProject requirementProject specificationTailoring toolsProject managementConference Paperhttps://doi.org/10.1109/IADCC.2009.4809266PubMed ID :
