Discuss about the three streams

There come times, however, when these three streams are joined. An event in the political stream, such as a change in administration, calls for different policy directions. At that point, proposals that fit the political event come to the fore and are coupled to the prevailing political climate. Or a pressing problem demands attention and a policy proposal is coupled to that problem as its solution. At points along the way there may be partial couplings:

• Solutions to problems, but without a receptive political climate.
• Politics to proposals, but without a sense that an important problem is being solved.
• Politics and problems, but without a clear policy alternative to advocate.
