Identifying result indicators is more complex. The United Nations treaty bodie shave developed guide lines on the form and content of reporting and general comments, both of which specify data requirements for country reporting (see www.ohchr.org). These reference documents are quite comprehensive. Institutions may use them as a template from which to choose the most relevant and important indicators for their particular monitoring activity.
An institution may have to define its own success indicators in some circumstances. If so, it is important that the indicator should be relevant, understandable and usable. A good indicator measures what it says it measures.
