Mary and Bob still need your help with wedding planning and are now requesting a resource estimate for the wedding. Because we have not identified specific resources (i.e. providers/vendors) we are still in the estimation phase. Use both analogous and bottom-up methods to help the happy couple. Normally, using analogous methods would have us estimate that a Mary and Bob's wedding would cost about the same as a similar-scope wedding with the same number of attendees (comparing the wedding as a whole to a proposed wedding). You're going to dig a little deeper. Note that this is an estimate, NOT an acquisition plan, which you will do in the next module
