Hi frens as far as my opnion is concernd abt this topic is that...Every Spec has its own pros as well as cons too...one must do self SWOT(Strength,Weakness,Opportunities n Threats) by taking certain measures to evalute n thn choose which one best suits to him/her. I cant b able to scale these all progs..if maketing bring revenue , than on other side HR motivates n organise teams to earn those revenues...without employees contribution former aspect is seem impossible...whereas MIS give them a cutting edge to earn those revenues in a Systematic n quicker way...See all these are interdepent,interrelated n integrated fields...Try ur exp. n analysis it in more effective manner...Thnx
