How to Measure Law Firm Partners’ Soft Skills, Leadership Capabilities

Law firm leadership faces a persistent measurement gap. The soft skills that most reliably predict a partner’s long-term contribution are often the hardest to quantify, as Edge International Principal Nick Jarrett-Kerr writes.

Firms routinely reward billing totals and origination figures while overlooking relationship-building, mentorship, and judgment under pressure. But those skills shape a practice’s durability far more than short-term numbers.

Organizations built traditional partner evaluation frameworks around metrics that are easy to tally but poorly correlate with sustained success. Client loyalty, talent development, succession planning, and cultural stewardship unfold over years, not billing cycles.

Their absence typically becomes visible only after damage has already occurred, whether through a lost client, an associate exodus, or a failed leadership handoff.

The article highlights several partner competencies that are difficult to evaluate and require new ways of gathering information to measure their value. They include:

• Relational skills: How clients and colleagues experience working with them.
• Long-term contributions: Future-focused efforts like succession planning.
• Behavioral traits: Intangibles like commercial instinct.
• Culture-related competencies: Practices like cross-team collaboration and ethical leadership.

Partners in formal leadership roles face additional demands including vision-setting, coalition-building, and managing underperformance.

The proposed remedy borrows an “investigator” assessment model from educational research. Instead of making snap judgments, assessors gather evidence through observation, hypothesis, verification, and refinement before drawing conclusions. The article draws a parallel to the litigation process.

“A good litigator does not form a view on the merits and then select supporting evidence; they investigate, assess, and then conclude,” Jarrett-Kerr writes.

How managers deliver feedback matters just as much. Leading conversations with questions and specific behavioral examples drives more genuine change than delivering general impressions as final verdicts.

Firm leaders evaluating internal governance structures should consider how board and management committees currently weigh soft competencies in partner advancement and succession decisions. Gaps carry real enterprise risk implications for client retention and talent pipelines.

Firms revisiting fiduciary and management accountability may want to formalize evidence-based observation protocols rather than relying on informal impressions.
