Step 5 : Draw Network diagram For Example, Identify number of buildings and number of floors per each

location.

Example :- An organization has,Headquarters with 4 buildings and 5 floors eachProvincial offices.BranchesRegional officersRemote officersCustomer service points.

M.Sc. in IT - Year 1 Semester II - 2012

Different number of buildings and floors
