The Question
BehavioralManaging and Elevating Underperformance
Tell me about a time you recognized a significant performance gap in a direct report or a peer you were leading. How did you diagnose the issue, what specific steps did you take to address it, and how did you balance the need for team delivery with the individual's growth? What was the final outcome for both the individual and the project?

Clarifying Questions
"To provide the most relevant example, are you more interested in a situation involving a technical skill gap, a lack of soft-skill alignment (like communication or ownership), or a general drop in productivity due to external factors?"
"Are we focusing on a scenario where I managed this person directly as a People Manager, or where I influenced them as a Tech Lead without formal authority?"
"Would you like me to focus on a situation that resulted in a successful turnaround, or one where we had to move toward a managed exit?"
Assumptions for this response:
I am acting as a Senior Tech Lead with some people management responsibilities.
The underperformance was a mix of technical debt/context gaps and low morale following a project shift.
The outcome was a successful turnaround through structured coaching and objective goal-setting.
Coach Strategy
Signals: Empathy, Radical Candor, Performance Management, Mentorship, Analytical Thinking (root cause analysis), Objectivity, Accountability, and Growth Mindset.
The "Diagnostic" Approach: High-signal candidates don't just "tell someone to work harder." They diagnose the why. Is it a "Skill" issue (they can't do it) or a "Will" issue (they don't want to/are demotivated)?
Cheat Code: The "Success Plan" vs. "PIP." Using the term "Performance Success Plan" suggests a proactive, supportive leadership style that aims to help the employee before HR needs to get involved. It shows you value the person but hold a high bar for the work.
Strategy Breakdown
The STAR Narrative
Situation – Context
I was leading a team of eight engineers developing a high-throughput data processing engine.
A Senior Engineer, "David," who had historically been a solid performer, began missing sprint commitments and delivering code that failed integration tests, causing a 20% delay in our release roadmap.
Team morale was dipping because other seniors had to spend extra time fixing David's regressions, leading to silent frustration during retrospectives.
Task – Your Responsibility
As the Tech Lead, my responsibility was to identify the root cause of David’s decline and either coach him back to his previous high-performance level or make a hard decision regarding his role on the team.
My specific goal was to see a measurable improvement in his PR (Pull Request) quality and "Definition of Done" adherence within a 4-week window without further damaging team cohesion.
Action – What You Did
Empathetic Diagnosis: I scheduled a private 1-on-1 and used "Radical Candor"—directly addressing the specific data points of missed deadlines while showing personal care. I discovered that David felt "lost" after our recent migration to a new tech stack (Rust/K8s) and felt it was "too late" to ask basic questions.
Collaborative Success Plan: Instead of a formal HR PIP, I created a "Technical Growth Roadmap." We identified three specific technical gaps and paired them with internal documentation and a $500 budget for a targeted advanced course.
Scaffolded Autonomy: I assigned David as the "Reviewer 1" for a smaller, less critical sub-module. This forced him to engage with the new codebase's patterns without the pressure of being the sole author.
Tight Feedback Loops: We moved to bi-weekly 15-minute "micro-syncs" focused exclusively on his blockers. I shifted my role from "supervisor" to "coach," performing pair-programming sessions twice a week to model the architecture standards we expected.
Result – Outcome & Impact
Quantifiable Recovery: Within six weeks, David’s PR rejection rate dropped from 45% to under 10%.
Velocity Increase: He successfully led the delivery of a critical data-sink module, which helped the team catch up to the original roadmap, eventually hitting our Tier-1 launch date.
Cultural Ripple Effect: David later presented a "Lessons Learned" session on the new tech stack, which helped onboard two junior hires. This transformed a potential attrition risk into a leadership opportunity for him.
Learning / Reflection – Growth
This experience taught me that underperformance is rarely a lack of "talent"; it is usually a mismatch between a person's current context and the available support structures.
I learned to "fail fast" in communication—addressing the first missed deadline immediately with curiosity rather than waiting for a pattern to emerge. I now incorporate "Skill-Will" matrix checks into my regular 1-on-1s with all reports.
