Answer:
I should encourage Dionne to use groups to make decisions because all of the members will be able to contribute their ideas in the decision-making process. This will make the decisions more effective than that of individual decision-making.
Explanation:
"Decision-making" refers to the process of making a decision by gathering relevant information. This could be done by an individual or as a group.
An "individual" decision-making process is<em> less costly</em> than a group decision-making. It also takes <em>lesser time</em> and is <em>great for emergency case.</em> The quality of the decision will largely depend on the <u>expertise of the individual</u>.
On the contrary, a group decision-making process is provides an effective decision due to the collaboration of ideas from all the members. Thus, creativity of all members foster in such process. This is especially a good option, if there is an <em>ample amount of time</em> in making the decision.
