Final answer:
The 'processing' phase is where the actual decision is made in the decision making process, after analyzing input and options.
Step-by-step explanation:
During the decision making process, the phase that involves making the actual decision is 'processing.' This phase is where all the previously gathered information (input) is considered and analyzed. It's the step where, after reviewing the situation and options available, one moves forward from just planning to actually determining the course of action to be taken. In business, this may relate to deciding on production elements such as the quantity of goods to produce, pricing strategies, and distribution channels. In the context of government and public policy, this stage would be similar to the enactment phase, where a solution is formally approved. Similarly, in the arts such as stage production, it aligns with the moment when the designer's selection is confirmed and the implementation begins.
