"I recently encountered a similar scenario to this. The project manager and I had worked together to create some amazing teams, but midway into the project, there was someone on the tech team who wasn't pulling their weight. To fix the problem, I first gathered together facts and evidence based on my own observations of the person's performance. Next, I provided them with immediate feedback so they had the opportunity to fix the problem. When the issue persisted, I arranged a meeting with them so we could discuss the problem and come up with a short-term action plan. This ended up turning the person's performance around. If it had not, I would have escalated the problem to their manager. Luckily, in this case, that wasn't necessary and the team member drastically improved their performance after our meeting."
