The author did a really good job of pointing out problem of promo culture, but the solutions suggested are more inspirational than actionable.
All founders/execs/early employees are easily aligned on compabt success. But how do you align incentive of later hires?
In order to reduce time spent on perf, you'd have to rely on a few people who knows an employee's work instead of a larger peer group and committee. The person entrusted with this decision (typically the manager) now wields tremendous amount of power over others. This leads to a different set of problems, like "B player hires C player", yes-man culture, ICs spending effort brown nosing instead of creating value, etc.
Building a culture is all about incentives, it's easy to identify and reward user/company impact when the team is small. But as number grows, it becomes harder to do that, and the declared core values gets ignored as the reward system departs from that.
