在与《哈佛商业评论》的莎拉·格林进行的一次富有洞察力的讨论中，沃顿商学院教授彼得·卡佩利，同时也是《我们为何爱恨人力资源，以及人力资源能做些什么》一书的作者，深入探讨了人力资源（HR）职能的历史演变、当前挑战和未来潜力。 卡佩利首先追溯了人力资源的起源，指出它在一战期间伴随员工甄选测试而出现，并随后随着科学管理（泰勒制）的发展而壮大。历史上，人力资源（当时称为“人事部”）的作用是向工程师和以财务为导向的业务领导解释人类行为和管理需求。其影响力随着经济状况起伏不定；在工会强大或劳动力市场紧张时期，它变得至关重要，但在经济衰退期，当管理者觉得他们可以“滥用员工而他们也不会辞职”时，人力资源部却常被视为“眼中钉”。这种历史模式使人力资源部成为一个经常提出让其他人不满要求的部门。 卡佩利认为，“爱恨交织”动态的核心源于人力资源部扮演的“唠叨”角色。人力资源是唯一一个告诉所有人，从底层职员到首席执行官，“他们应该如何行事”的职能部门——例如进行绩效评估、传达坏消息或避免不当行为。这种指导意见常常与管理者的强烈主张和对自主权的渴望发生冲突，从而导致摩擦。虽然人力资源部旨在充当“总经理”，考虑更广泛的组织影响（例如，一名员工的加薪会影响到其他人），但卡佩利指出了一个关键的失败之处：人力资源部往往未能充分解释这些政策 *为何* 存在，导致管理者感到受阻而非得到支持。 卡佩利提出了人力资源部可以提升其地位和影响力的几个关键领域： 1. **证明投资回报率（ROI）：** 历史上，人力资源部在证明其政策的投资回报率方面表现不佳。在一个日益关注财务指标的商业世界中，人力资源部需要量化其实践（例如招聘方法、留任奖金）的有效性和成本效益。否则，这些做法就会被视为缺乏证明价值的“最佳实践”而遭到驳回。 2. **拥抱数据和分析：** 随着“大数据”的兴起，首席信息官等其他部门开始分析人力资源数据。如果人力资源部不掌握这一分析职能来回答关键业务问题，它就有被淘汰的风险。 3. **支持项目制工作：** 公司正从宏大、长期的战略转向更快、更短、基于项目的协作。人力资源部需要将其重点从使实践与广泛战略保持一致，转向积极支持这些动态项目，包括管理合同工以及决定何时外部招聘而非内部晋升。卡佩利批评人力资源部“过于偏向外部招聘”，从而忽视了内部发展。 反之，卡佩利也指出了人力资源部浪费时间并削弱自身权威的领域： * **代际研究：** 专注于“千禧一代”、“Z世代”等往往是在浪费时间。几乎没有证据表明这些代际差异会对管理产生深远影响，即使有，人力资源部的角色也只会再次沦为“唠叨”主管去适应。 * **多元化倡议（在没有权威的情况下）：** 在大多数公司中，多元化是一个文化问题，需要高层领导力，而不仅仅是人力资源部的倡议。人力资源部常常承担起它缺乏有效实施权限的项目责任，导致更多的是说服，而实际成效甚微。这也适用于其他项目，即人力资源部试图“唠叨”管理者遵守规定，但却没有奖惩的权力。 最后，卡佩利提供了全球视角。他指出，在20世纪50年代的美国，人力资源曾是一个“光鲜的职业”，因为内部职业发展意味着人力资源部掌控着职业晋升。如今，人力资源的影响力差异巨大： * 在**印度**，由于技能短缺、强大的工会和复杂的劳动法律，人力资源部拥有强大的权力，这对企业成功至关重要。 * 在**日本**，由于其对内部职业发展和人际网络的掌控，人力资源在历史上一直是通往首席执行官职位的途径。 * 在**美国**，近年来人力资源部的影响力有所削弱，原因在于相对较高的失业率和熟练劳动力过剩，尤其是在大衰退期间，员工们“仅仅为有一份工作而感到庆幸”，这使得人力资源部变得不那么“必要”。 总之，卡佩利认为，人力资源部若想重拾其影响力并摆脱“唠叨”的名声，它必须通过数据驱动的洞察力来证明其切实的价值，适应项目制工作等现代组织结构，并将其精力集中在那些能够以权威真正影响业务的领域，而不是承担那些无法强制执行的责任。

In an insightful discussion with Sarah Green from Harvard Business Review, Wharton Professor Peter Cappelli, author of "Why We Love to Hate HR and What HR Can Do About It," delves into the historical evolution, current challenges, and future potential of the Human Resources function. Cappelli begins by tracing HR's origins, noting its emergence in World War I with employee selection tests and its subsequent growth with scientific management (Taylorism). Historically, HR (then "Personnel") served to explain human behavior and management needs to engineers and financially-oriented business leaders. Its influence has waxed and waned with economic conditions; it became crucial during periods of strong unions or tight labor markets but was often seen as a "thorn in the side" during downturns when managers felt they could "abuse people and they don't quit." This historical pattern established HR as a department that often makes demands others resent. The core of the "love to hate" dynamic, according to Cappelli, stems from HR's role as the "nagging" department. HR is the one function that tells everyone, from the lowest clerk to the CEO, "how they're supposed to behave" – conducting performance reviews, delivering bad news, or avoiding inappropriate conduct. This guidance often clashes with managers' strong opinions and desire for autonomy, leading to friction. While HR aims to act as a "general manager" considering broader organizational impacts (e.g., a raise for one employee affecting others), Cappelli notes a crucial failing: HR often doesn't adequately explain *why* these policies exist, leading to managers feeling obstructed rather than supported. Cappelli offers several key areas where HR could improve its standing and impact: 1. **Demonstrate ROI:** Historically, HR has been poor at proving the return on investment of its policies. In a business world increasingly focused on financial metrics, HR needs to quantify the effectiveness and cost-benefits of its practices (e.g., hiring methods, retention bonuses). Without this, practices are dismissed as mere "best practice" without proven value. 2. **Embrace Data and Analytics:** With the rise of "big data," other departments like the Chief Information Officer are starting to analyze HR data. HR risks obsolescence if it doesn't take ownership of this analytical function to answer critical business questions. 3. **Support Project-Based Work:** Companies are moving away from grand, long-term strategies to faster, shorter, project-based engagements. HR needs to shift its focus from aligning practices with broad strategies to actively supporting these dynamic projects, including managing contract workers and deciding when to hire externally versus promoting internally. Cappelli criticizes HR for "straying too far toward outside hiring," neglecting internal development. Conversely, Cappelli identifies areas where HR wastes time and diminishes its authority: * **Generational Research:** Focusing on "millennials," "Gen Z," etc., is often a waste of time. There's little evidence these generational differences profoundly impact management, and even if they did, HR's role would again be reduced to "nagging" supervisors to adapt. * **Diversity Initiatives (without authority):** In most companies, diversity is a culture issue that requires top-level leadership, not just HR initiatives. HR often takes responsibility for programs it lacks the authority to implement effectively, leading to more persuasion and less tangible results. This applies to other programs too, where HR tries to "nag" managers into compliance without the power to reward or punish. Finally, Cappelli offers a global perspective. He notes that HR was once a "glamorous profession" in the U.S. in the 1950s because internal careers meant HR controlled professional advancement. Today, HR's influence varies significantly: * In **India**, HR is powerful due to skill shortages, strong unions, and complex labor laws, making it critical for business success. * In **Japan**, HR has historically been a path to the CEO role due to its control over internal careers and networking. * In the **U.S.**, HR has weakened in recent years due to relatively high unemployment and an oversupply of skilled labor, especially during the Great Recession, when employees were simply "glad to have a job," making HR less "necessary." In conclusion, Cappelli argues that for HR to reclaim its influence and escape its "nagging" reputation, it must demonstrate tangible value through data-driven insights, adapt to modern organizational structures like project-based work, and focus its energy on areas where it can genuinely impact the business with authority, rather than taking on responsibilities it cannot enforce.
