Inductive reasoning
Inductive reasoning moves from specific details to broader generalizations². Informally, we sometimes call this a "bottom up"approach. Inductive reasoning begins with specific observations and measures of detailed³ tasks and assignments, which are then categorized and classified into functional⁴ activities (e.g. Sales,
Marketing) to form general plans and strategies.

归纳推理是从具体中归纳普遍的规律。通俗地说，我们有时称 之为“自下而上”的方法。归纳推理始于对详细工作及任务的具 体观察和衡量，然后将之分类成各种功能性的活动（例如：销 售、市场行销）从而形成总的规划和策略。
