What is a weakness of the traditional problem-solving model? a) its need for implementation time b) its lack of a step requiring evaluation of results c) its failure to gather sufficient data d) its failure to evaluate alternatives

It needs implementation time

Explanation:

Traditional problem solving method required a lot of time starting from understanding the problem, gathering materials, surveys, developing code entirely a new one and many tings were statics and based on approximation. However in modern times we have many approaches right from agile coding style, heuristic, greedy approaches and many dynamics methods.
