Systems Thinking

Systems Thinking
Companies have designed new and improved ways to solve problems within their organizations. Rather than seeking a simple cause and a direct solution to problems, companies are now using an approach called systems thinking. Systems thinking involves solving problems long-term by considering the “big picture,” that is, how the interaction of many different parts of a large system may contribute to a problem. Companies use systems thinking because, even though it may produce complex solutions that take a long time to implement, it is an effective way to solve problems and has a greater long-term benefit to the company.

NARRATOR

Now listen to part of a lecture on this topic in a business class.

MALE PROFESSOR

For example, I used to work for a corporation that was having trouble with workers being absent a lot.

To help address this problem, they hired a consultant, who began by interviewing a lot of the workers, and getting to know more about them. She also researched other aspects of the company, such as the types of eating facilities and health services it offered. And what the consultant discovered was that many of the employees were missing work, not for an obvious, simple reason like, say, lack of motivation, but because of...health problems...health problems that were the result of, or at least made worse by, a combination of factors such as poor eating habits and lack of exercise. The consultant concluded that since the company didn’t offer exercise opportunities or healthy meals, that this indirectly contributed to the workers’ poor health.

The consultant proposed building a gym within the company office building for employees to use to exercise; and also to offer a more nutritious menu in the cafeteria. Which the company did, but it took a while. And after a year or so, after the company had time to construct a gym and revise its cafeteria menu, attendance began to improve. And continued to improve until it was no longer a problem.

问题

Explain how the example discussed by the professor illustrates a systems-thinking approach to problem solving.

分数说明

1. Speech Rater 系 ETS 在托福考试中真实使用的口语机评系统,具有很高的参考价值。因真实的考试中还有人类评分的环节,因此机器评分不能简单等同于最终的考试分数

2. 经过考满分老师已经对用户数据分析,建议评分报告中重点关注以下维度:语速、连贯度、停顿频率、词汇或短语重复频率、重音与节奏、元音饱满度等。词汇、语法两个维度可能会因为录音设备的不同以及人类评分的权重,评分有一定的偏差。(我们会不定期分析数据,更新该部分说明)

3. 录音环境嘈杂或录音声音太小可能会导致无法评分(请尽量保证安静录音环境)

4. 经过对测试用户口语成绩数据分析,考满分老师为大家提供了 SpeechRater™ 与真实考试分数的对应关系,供参考:
