Any Executive Branch agency wishing to invest in an IT project (new or enhancements to existing systems and applications) that costs more than $50,000 must develop a business case with a Technology Investment Request (TIR) form. TIRs are required for Executive Branch agencies as part of their biennial budget process as well as for interim funding of IT projects.  They apply regardless of the funding source (including grant funding), as well as in situations where the funding already exists and the agency is requesting authority for expenditure. The TIR must be submitted to DoIT for review and approval prior to submittal to the Budget Division.
