QUESTION: What System Development Life Cycle (SDLC) approach assumes the project can be
planned completely in advance? - ANSWER-Predictive - Predictive SDLCs are useful for building

(RFP), to potential vendors asking for specific information about the patient portal. - a letter to
request information (RFI) is sent to check for compatibility with existing systems and specific
information. Once that step is done, a letter is sent for more specific detail, called a request for
proposal (RFP) that provides detailed functionality, approximate costs, and an expected
timeline so the vendors that meet the practice's goals can be identified (budget, timing,
functionality, etc.).
