"
“Eight years ago, our firm’s profits were increasing with each new employee we added. We discovered that each employee had the skills and motivation to generate more revenue for the firm than his or her salary cost us. However, for the past two years, our profit margin has been falling, even though we have continued to add employees. Thus, our newer employees are not generating enough revenue to justify their salaries. We must not be hiring new employees with the same level of skills and motivation as those we used to attract. Clearly, then, failures in the human resources department account for our falling profits.

Flaws:
1) Mistaken correlation with causation or Causal Oversimplification. Although the new hires from the last two years correlates with the profit drop, it does not means that the former causes the later.
2) Since the qualifty of the new hires are constant, the drop in revenue probably results from some other factors such as the retention rate of new hires, the mechanism to reward high-achiever among new hires, the overall trend of the industry, the success of the competitors, etc.
3) Most importantly, the vision of and the guidance from the upper management might affect a new hire's performance in the firm. To put the blame of falling profit on the the shoulder of HR is unfair, short-sighted, and demoralizing.
