The Lindbloom's
disjointed marginal incrementalism model compares policy making as a mere cosmetic exercise. To him a planned and well thought policy is a rarity and policy making process is fraught with adhocism which he regarded as the "
Science of muddling through".
The above proposition may hold some substance in practical life but the truthfulness of the entire idea is doubtful. Dror has criticized the idea for being too complacent in nature. This mindset introduces a sense of laxity in the administration. This laxity becomes a vital reason for failure to introduce radical changes and afresh ideas in the policy conceptualization.
Further, in prismatic society like India, China etc where Policy paralysis is galore, the incrementalism has only served short term goals. For instance, our taxation policy is a result of episodic changes which has only resulted in shortfalls in our tax revenues. Major reforms like GST, GAAR , Direct tax code which are beneficial for long term are still pending due to incrementalist approach.
Similarly, post positivist policy study too has advocated for other policy models which are able to address short and long term needs.
However, complete departure form Incrementalism is neither possible nor desirable. To mitigate its weaknesses, Etzioni's Mixed scanning model can be an alternative for serving short term & long term needs both. This model favors incrementalism in areas like foreign policy etc and radical reforms in areas like health, education, skill development etc.
Thus countries requires a balanced approach in policy making process which is possible by utilizing the benefits of every bodel and reducing their loopholes.
