I copied this from wikipedia so I hope the pic of the chart shows up. It is interesting to read things about the religion in a completely unbiased format. It puts things/sheds light in a more simplified manor. Sometimes just looking at the basic structure of something allows the overall scheme of things to become much more obvious.
The leadership of Jehovah's Witnesses was reorganized in 1976 and the power of the presidency passed on to the Governing Body of Jehovah's Witnesses . Subsequent presidents of the Watch Tower Society after Knorr's death in 1977 have been Frederick William Franz , Milton George Henschel and Don A. Adams . However, doctrinal and organizational decisions since 1976 have been made by the Governing Body.  The Writing Committee of the Governing Body now edits all Witness publications. Congregation affairs are under the direction of the Service Committee of the Governing Body. 
Matthew 24:45 depicts a "faithful and discreet slave" who is "appointed over" others to "give them their food at the proper time."
Effect of Current Doctrine on Teaching Authority
Although the Faithful and Discreet Slave is believed to be the earthly source of doctrine for Jehovah's Witnesses , very few from this group have any decision making authority regarding institution of doctrine, changes to doctrine, or decisions relative to Jehovah's Witnesses worldwide. All decision making authority with regard to doctrine is vested entirely in the Governing Body of Jehovah's Witnesses .
((((doctrinal and organizational decisions since 1976 have been made by the Governing Body.  The Writing Committee of the Governing Body now edits all Witness publications. Congregation affairs are under the direction of the Service Committee of the Governing Body. )))
"'The faithful and discreet slave' seeks to preserve unity and makes it possible organizationally for 'all things to take place decently and by arrangement.' (1 Cor. 14:40) To accomplish this in the first century, a group of anointed Christians from among the faithful and discreet slave class were chosen as its representatives. As such, they did not consult with all anointed elders in the world before making decisions. From their position in the Jerusalem congregation, they served as a governing body for the entire anointed Christian congregation." 
In contrast, new members of the Governing Body today are selected only by existing members of the Governing Body, and members of the Faithful and Discreet Slave class do not at all choose their representatives. Given this reality, the effect of current doctrine on teaching authority is that the teachings of Jehovah's Witnesses are coming, not from the Faithful and Discreet Slave, but from the Governing Body. The Faithful and Discreet Slave is not listed in the Organizational structure of Jehovah's Witnesses and the Governing Body is in no way subject to this group. Individual members of the Faithful and Discreet Slave also risk disfellowshipping for publicly rejecting the teachings of the Governing Body. It is difficult for any outside observer to determine where the Faithful and Discreet Slave, as a class, has actual authority over anything.
