With our current knowledge limited by the absence of physics data, I review our expectations from standard processes measurements at the LHC. Focusing on charged and neutral current processes, I illustrate how their measurement will constrain our uncertainties on discovery physics, and give some arguments about our precision goal for the W mass measurement. Detailed analysis reveals that there is no reason to believe we can not measure this fundamental parameter to about 5 MeV, most uncertainties (of both experimental and theoretical source) being constrained by a detailed measurement of Z production.
