Existing system - political party

The system of running a government, the laws, people's practices and democratic practices..... this all should be optimized for the new age. We need to run the government as efficiently and transparently as possible.

When I look at the elements as listed in http://evolvingfromdemocracy.blogspot.com/2009/03/how-democracy-is-working-now.html
We have these things:

1. politicians
2. political parties
3. voting
4. democracy process authorities

I do see that the element 'political party' have got a lot of responsibilities, which was not called for.
The system was designed around it, so there are a lot of 'rituals' that we have to carry out at various processes.

The symptoms that show the problems with the system:

1. No political party is able to get the clear majority, causing unnecessary instability
2. Political parties forge various groups that tread with each other and forster malpractices
3. Political parties forming their diplomacy based on wrong policies (may be 'enemy of the enemy is a friend' or to keep their major competitor away from the power)
4. No responsibility borne by the political parties for their misbehavior.
5. Increased complexity in the democratic processes and overheads for managing party leadership, party discipline, informal group-ism
6. Lack of transparency in the party operations
7. Individual candidates not able to relate their policies of the local issues with the party policies, sometimes, failing to manage the conflict

These are only the problems and overheads we have to take the burden of. The disadvantages are many

1. Governments with different parties not collaborating with eachother
2. Government changing its policies implemented by earlier governments led by competing parties, just for the sake of rivalry and showing them as failure.
3. Use of influence on the independent authorities e.g. president, governors, police or other forces, to trouble other governments led by competing parties.
4. Candidates taking incorrect approaches to impress the party leadership to seek advantages.
5. Sometimes, fostering corruption under the name of party integrity or discipline.

Some advantages I am able to think of:

1. Focused development, if the party leadership is competent and honest, and the government is a single party majority one. This has a few points helped (for good or bad) in the initial years of the independence.
2. Support for the new candidates.

So, surely the disadvantages are over-weighing the advantages. Also the people have learned ways to manipulate the system. The democratic system is not able to address such issues due to lack of the responsibilities attached to the parties.
The political parties are given undue importance in the democratic processes. We could have better arranged the system around policies much more tightly, rather than giving the parties the freedom to work irresponsibly.
