How can we do the effort estimation for Production support projects? Need to decide count of resources in L1,L2 and L3?
I have 2 projects -
1)Apps with few months of Ticket details 2)Apps with No Ticket Details
Approach I am planning to take :
1)Case 1:I have ticket details and i have taken weightages related to technical ,application complexity etc. and productivity factor i.e. no of tickets per month that can be solved by L1,L2,L2,%distribution of L1,L2,L3, Average Tickets for L1,L2andL3 and based on that decided on the L1,L2,L3 count
2)Case 2:I have taken the application size i.e. LOC, converted it to Function Point and based on productivity factor decided number of resources, then decided on the some % distribution to L1,L2 and L3.
