“…Leppänen (2013) presents a nice overview of these agile maturity tools selected with the following criteria: "Domain" (the domains the models are targeted to), "Purpose" (the purposes the models have been developed for), "Conceptual and Theoretical Bases" (the conceptual and theoretical backgrounds upon which the models have been built), "Approaches and Principles" (the approaches and principles used to construct the models), "Structure" (the architectures of the models), and "Use and Validation" (extent of deployment and validation). Based on these criteria eight tools were selected: The Agile Maturity Model (Ambler, 2010), A Road Map for Implementing eXtreme Programming (Lui & Chan, 2006), Toward Maturity Model for Extreme Programming (Nawrocki et al, 2001), The Agile Maturity Map (Packlick, 2007), Agile Maturity Model (Patel & Ramachandran, 2009), Agile Maturity Model (Pettit, 2006), A Framework to Support the Evaluation, Adoption and Improvement of Agile Methods in Practice (Qumer & Henderson-Sellers, 2008), and The Agile Adoption Framework (Sidky et al, 2007). According to Leppänen (2013) some of them are merely based on conceptual studies, others are developed only in one organization, a third group has gathered more experience from organizations, and some are discussed with practitioners.…”
