[Synthetic Nursing Index.  An instrument to measure correct self-management]. 
Continuous improvement in quality assistance and efficiency of use of the sanitary resources demands professionals to consider the necessity of offering greater and better quality starting from the base and the tangible reality which we can rely upon (we have what we have, and we have to develop our activities based on these).  To offer the greatest possible quality (we start off on the premise to diminish costs of non-quality: that which is done but provides no value to users, and what we have difficulty repeating that which was not done properly the first time) the Project for Participative Self-management (PAP) has been started, a project which indirectly will permit opting to get a variable economic compensation according to profits earned.  And, since it is not ethical not licit that there be "something for everyone" (café para todos), nor that the distribution be equal for everyone, a tool has been created called the Synthetic Nursing Index (SNI/ISE), which enables each nursing professional to receive compensation based on some indicators.  These indicators will evaluate if the quality offered and the improvement in costs of those non-quality items has obtained a greater or lesser consecution percentage.  The SNI/ISE is a global clinical-care product indicator generated by "the Team", summarizing in one unique value a set of individual indicators, thereby facilitating its interpretation.  Thanks to SNI/ISE, it will be possible to justify why each nursing professional does not receive the same variable compensation quantity recognizing and rewarding the work performed by each professional in an individual manner.
