what improvements can you plan in the normal network monitoring process ?

If this is a school ignment - do your own work. If this is actually work related - congratulations! You have just learned what most high end people in the networking sector already knew: More than half of those who put themselves out as "Networking Guru's" are clueless and tend to cause more problems than they fix. Anyone with a Microsoft networking certification is worthless. Only Cisco CCIE types are worth their salt because it is so hard to get the certification. In your example it's only an 80 person company so this is a simple solution to find.
