1. Purpose/Instrumental rationality: Max Weber was one of the theorists to first explain it. The work of instrumental rationality is to emphasize the result a specific available or a concept based effort can produce. It ignores the fundamental question of the real world aftermath forming from the use of that effort. Scientific method, experts and power flowing from top to bottom are all expressions of this rationality.
Weakness: It has a tendency to leave the lower level public servants in the dilemma of ethics, for not every instruction can be converted into words flowing from top to bottom.
2. Efficiency: This means that any program to be approved and started must show result and adhere to the common ideology of the country. Anything that does not work must be eliminated. In short, the depiction of performance measurement is very important.
Weakness: Performance measurement has always been an issue. There is no way to measure every work of the government. For instance, certain environment programs can take years to show signs of result. Hence, the idea of efficiency for them is blurry.
3. Professionalism: This refers to all the factors that the public employees must abide by while doing their work.Values are the examples of this. For instance, to prevent fraud and biases, the government has rules promoting transparency and fairness. Anyone failing to abide by them can be penalized. Professionalism also takes into account the knowledge of the employees connected to their work. What this means is that not just anyone is allowed to make laws or handle criminals. Such tasks are given to lawyers, judges, cops and the military. All of them must abide by procedural policies.
Weakness: Professionalism certainly is necessary in all organizations. However, its weakness is in how the professionals are perceived as all knowing which unfortunately is not always true.
