Today I came across a piece of news about Li Auto: an internal company announcement revealed that HR head Yang Haishan now reports directly to CEO Li Xiang, and OKR has replaced PBC as the primary performance appraisal method. Over the past year, the PBC model had triggered vicious competition within the sales team—issues like cross-region poaching and information hoarding. Now OKR is making a comeback, accompanied by the exit of former Huawei executives from management roles.

At first glance, this seems like a routine personnel adjustment. But the contrasting organizational responses triggered by these two performance tools reminded me of a question that has long puzzled me.

Back when I was an individual contributor, I felt that KPI, PBC, and OKR were essentially the same—complete tasks, await evaluation, collect bonuses. But as my role evolved from frontline worker to manager, and then to middle-level coordinator, I realized that subtle differences between these tools could significantly change how I made decisions, how I communicated, and how tolerant I was of failure. Every minor adjustment gets amplified within the organization, like the flap of a butterfly’s wings, creating ripples far beyond the tool itself.

Based on years of management experience, I’ve come to this conclusion: performance tools don’t really evaluate employees—they evaluate managers. Employee goals often come from their leaders, and the tools—through their cycle length, reward linkage, and evaluation methods—shape how managers think and behave. When managerial behavior is amplified by even small adjustments, it directly impacts the entire organization’s operations and culture. This is what I call the “butterfly effect”: small changes, amplified through managerial behavior, ultimately produce a completely different organizational landscape.

While writing this article, I also reflected on the history of performance culture. Here’s some context: In the industrial era, KPI and Taylor’s scientific management made workers highly controllable. In the knowledge economy, MBO and BSC allowed knowledge workers to participate in goal-setting, but managers still held the final say. In the internet era, OKR emphasizes self-motivation and tolerance for failure, while PBC emphasizes digital commitments and outcome constraints. Each tool evolution seems minor, but the core is always about changing how managers empower, supervise, and make decisions—and these small differences in managerial behavior are enough to create organizational butterfly effects.

Of course, these performance management tools also have distinctive real-world examples worth analyzing. Google and ByteDance’s OKR success isn’t about the template—it’s that managers spend time discussing the “why” and the “what,” not the “how” and the “how much.” Xiaomi’s early dual-track system—OKR for executives, KPI for frontline staff—seemed flexible but actually created an identity gap within the organization. When Li Auto implemented PBC, the sales team’s vicious competition wasn’t a moral failure of employees—it was a system that made individual digital commitments the only measure of righteousness. Tools shape managerial behavior, and that behavior is amplified across the entire organization—this is the butterfly effect in its most direct form.

Therefore, the butterfly effect of performance appraisal should not be underestimated: a change in the assessment cycle, a tweak in how bonuses are linked, an expansion of goal transparency—any of these could, at some future moment, make employees suddenly realize, “We are no longer who we used to be.” This isn’t just about the tool itself—it’s the interplay of organizational culture, management logic, and power dynamics.

Ultimately, the tool itself is not the core issue. OKR, PBC, or dual-track systems each have their own historical logic and applicable scenarios. What matters is how managers use them, and whether the organization aligns them with its own culture and strategic goals. Li Auto’s restructuring appears to be a tool switch on the surface, but at a deeper level, it’s a recalibration of managerial behavior and organizational culture direction. The butterfly effect runs through it all: small changes, amplified through managerial behavior, shape the entire organization’s operating pattern—and reveal its truest soul.
