Who says it's notoriously difficult? I've worked many places with clear processes for identifying and resolving poor performance issues (firing being one possible resolution).

The crux of growth in knowledge workers is that our current norms of measurement and productivity were developed in a manufacturing or manual task-oriented mindset. According to Peter Drucker, productivity for knowledge workers needs a different set of considerations

While in manual work the targets and outputs are usually clear, knowledge work and its results are less tangible, and therefore harder to define, measure and evaluate

Drucker (1999) has even stated that knowledge worker productivity is the biggest challenge for modern work life. Other researchers have also discovered that the performance of an individual knowledge worker is the most important factor for organisational success... The need for general performance measurement is great as the theme is still quite new and there are very few previous studies measuring the effectiveness of NewWoW practices. There is also a need for practical tools for analysing and managing the performance of knowledge work from the NewWoW perspective. Organisations are still planning and making NewWoW changes, without clear evidence of their benefits and without any measurement information
Great, which means we have a way to measure individual performance with respect to what matters (organizational success). So what's the problem?

Unless you question the validity of the research? But if that's the case, why did you mention it as being significant in the first place?
Can you expand on that?
Clearly if it was possible to measure effectiveness unambiguously this wouldn't be a debate.
