GiventheacknowledgedimportanceofthisProject,thePanelinvestedconsiderableeffortindelivering anindependent,objectiveandunbiasedmanagementandprogrammaticassessmentoftheissues raisedintheletter. Insummary,thePanelconcludedthattheJWSTProjectisinverygoodtechnicalshape.Thereisno reasontoquestionthetechnicalintegrityofthedesignoroftheteam'sabilitytodeliveraquality producttoorbit.Theproblemscausingcostgrowthandscheduledelayshavebeenassociatedwith budgetingandprogrammanagement,nottechnicalperformance.ThePaneltookitsguidancefrom SenatorMikulski'slettertoyoudatedJune29,2010,includingthecarefulexaminationofthefourareas describedintheChairwoman'sletter,i.e.,rootcauses,currentplanstocomplete,changestodiminish theriskofcontinuedcostgrowthandscheduledelay,andminimumcosttolaunch. TherootcausesofcostgrowthandscheduledelayonJWSTwere: 1. TheJWSTBudgetpresentedtoHeadquartersinsupportoftheConfirmationReviewwas badlyflawed,principallybecauseitwasnotsupportedbyabottomsupestimate,nordidit includeprovisionforthethreatsandliensthattheProjectknewaboutatthetime. 2. TheAgencydidnotfullyrecognizethis,partlybecausethecostandprogramanalysis capabilityinexistenceatthattimedidnotpenetratetheflawsintheProjectBudget.The AgencydidrecognizesomeoftheproblemswiththeprofilepresentedatConfirmationand addedfundstocompensate,butthefullextentofflawedbudgetremainedundetectedand sotheaddedfundingwasinsufficienttosolvetheproblem. 3. TheinstitutionalcostandprogramanalysiscapabilityattheDirectorateandAgencylevel continuestofunctionwithouttheskillandauthorityrequired.Consequently,since Confirmation,demandforcorrectiveactionwasabsent,andpoormanagementpracticeson theJWSTProjectwentunquestionedfortoolong.

Theissueswiththecurrentplanstocompletemainlyrevolvearounduncertaintiesintheintegrationand testplan,which,asnotedintheTATReportofAugust2010,canberemediedbycarefulandthorough testplanning.

ThePanelestimatedtheminimumcosttolaunchJWSTwillbe$6.5billionforanearliestlaunchdateof September2015.Thiscanbecomparedto$5.1billionintheFY2011President'sBudgetRequest.
