This paper contains four sections. Following this introduction, section 2 addresses the dimensions of appropriateness and the conceptual backbone that informs the tool structure. Section 3 illustrates the inner workings of the tool, as well as describing the meaning of the various cells in the excel file. Finally, section 4 tackles the intended users and potential uses of the tool, in addition to discussing the tool’s limitations and the potential to develop it further. A series of annexes cover reviewers (One), the definitions of method, approach and technique on which the tool is based (Two), and provide basic information about the 11 methods included in the tool.
