Death by Committee.

Yeah I know. Not an original title. You've probably heard that phrase/fragment many times before, I was actually going to call it:
"Death by aneurysm caused by high blood pressure levels brought on by the frustration with the inaction, gutlessness and general pointlessness of a Committee." But that would have made the permalink too long....

There is only one good reason to form a committee - When you do not want to put too much dependence on the opinion of one man. In that case, you get a group of people with varied experiences and expertise to advise - and monitor the actions of - that one dude. For example boards of companies. But even then you will see that the dude (CEO in this case) is ultimately responsible.
But unfortunately, the real reason most committees are brought into existence are one of the below:
a). There IS A NEED for a person of influence and authority, but you have NOT APPOINTED one
b). There is NO NEED for a person of influence and authority, but you HAVE APPOINTED one.
c). A case of special disaster, where there IS A NEED, but instead of appointing a person and giving him authority, you have appointed a titular, incompetent, apathetic INVERTEBRATE.

The only case from the above three that has a chance of succeeding is case b. And that too if the person that you appointed is an exceedingly capable, dynamic and astute leader. And we all know there are very few of those types of people.

If you dont have an explicitly appointed owner for a set of decisions that do need to be made then what will happen is a set of reptiles with lower authority levels will get together and form a committee. Such committees are generally called councils. If the members are truly arrogant pricks, those committees will be called boards.
And what happens at these boards? Posturing, Grandstanding and Backstabbing - that's what. Nothing will ever get done by a bunch of airheads who are flailing like flagella to prove that they are better, and more important and their businesses more successful than the next one.
While there may not be much benefit to the company from such committees, YOU may be able to benefit. If you're capable of swimming with the sharks and playing their politics, you may benefit from the visibility to different businesses and the weaknesses of your competition. And you MAY get opportunities to prove that you're not the petty insecure manager that the others are by taking on something that you can herd the cats toward.

IN the case of special disaster, you're truly fucked. You get a committee of epic failure. It will do nothing, and will disrupt the functioning of various divisions in the company.
When you hire a incompetent apathetic invertebrate and put him in a position that has explicit organizational power, that's bad enough. But generally you will find out quickly he's bad and you can get him out.
But when you put such bastards in a position where there is low organizational authority but where he has to rely on inferential authority or generating influence then he WILL form a committee. Possibly many. And none of them will do anything.
Such insects never give as much as a fly's asshole about what is done or how fast it is done, or whether it is done, but the WILL care about giving out the impression that THEY tried. IF anything didn't happen it's because of the environment, external factors, and other people.
These are committees you should never ever be a part of. Ever.

(Oh and Virat Kohli's century doesn't change the fact he still has miles to go before he proves himself to be worthy. If it were left to me, I would drop him from the team on the basis that he looks like a retard and is overrated. The only thing Virat about him are his eyebrows.)
