   Putting 10 or 20 people on a supposedly 5 man month project is   
   highly unusual and not likely to work well.

   Team size one is what gives the highest productivity.   
      
   But many tasks are too big for one person.   
      
   systemd with 1.7 MLOC was mentioned recently.   
      
   If Redhat had put one engineer on it then productivity   
   would have been great (no project meetings, no endless   
   design discussions, no handover of information etc.),   
   but it would take hundreds of years to complete.
