Key Performance Indicators ("KPI")
Those project management indicators that:
are determined at the beginning of the project
reflect directly on the key objectives [goals] of the project
provide the basis for project management trade-off decisions during the course of the project.
And at completion of the project these KPIs:
will be the most relevant measures to confirm the acceptability of the project and its product by the project's stakeholders as being "successful"
can be measured in some way, at some time, on some scale.

Yo lo pondría así en lugar de "indicadores clave de rendimiento medidos" que suena feo. Como bien dice Claudia, KPI son key performance indicators.
