Sumario:New misalignment scenarios are implemented for the CMS Tracker as a set of working hypotheses for simulation studies. Educated guesses of random misalignments are applied to various geometrical structures. $\chi ^{2}$-invariant deformations are not simulated. The new scenarios are called as SurveyLASOnly, SurveyLASCosmics, $10\, {\rm pb}^{-1}$, $100\, {\rm pb}^{-1}$ and $1000\, {\rm pb}^{-1}$ scenarios, and they correspond approximately to the respective situation. Details of the scenarios and a list of possible future improvements are discussed. The impact on track reconstruction performance and Z mass reconstruction are also discussed.
