How would you handle a teammate who repeatedly misses agreed deadlines?

First discuss the situation privately and ask about obstacles rather than assuming lack of effort. Clarify the deliverable, dependencies, and realistic milestones, then agree on visible progress checks and support. Explain the effect on the team calmly. If commitments continue to slip, raise the delivery risk with the project lead using facts and attempted remedies. Avoid taking over every task without discussion or criticizing the teammate publicly. A good response balances empathy with accountability and keeps the project’s shared commitments visible.
