A software engineer starts missing deadlines, and the quality of their work changes. Underperformance means falling below a role’s expected standards for delivery, quality, or behavior. Identify it early so the employee has a chance to improve and the team can plan around the impact. section 4.5 section 4.5.1
For an individual, move from observation to support rather than jumping to a conclusion:
- Identify specific changes, such as missed deadlines, lower work quality, or reduced engagement. Use one-on-ones and performance reviews to give continuous, actionable feedback; the concern should not come as a surprise. section 4.5.1
- Investigate the root cause without personal bias. Consider skill gaps, personal concerns, role fit, missing resources, unclear expectations, or changing interests. section 4.5.1
- Match support to the cause. Mentorship and training may address a skill gap; a different role may better fit changed interests. Use a coaching plan to track improvement, and consider a performance improvement plan if performance does not improve. section 4.5.2 section 4.7
Two different outcomes
An engineer whose interests had shifted toward project delivery shadowed a technical program manager and moved into that role within three months. Another engineer improved technical skills through mentorship and training in a 60-day coaching plan. Underperformance does not always end in termination. section 4.5.2
If a whole team misses commitments, investigate the system as well as individual performance. Repeated sprint spillovers, for example, traced to duplicate work, poorly communicated absence, and slow code reviews. Observe team dynamics, clarify expectations, seek other perspectives, and remove process blockers. section 4.5.4
A cross-functional partner may also be struggling, even when you are not their manager. Validate the concern through feedback, offer resources or mentorship, and work with their manager on concrete goals. Ask: what have I observed, what might be causing it, and what support can I offer? section 9.1.7 section 4.5.1
