How Not To Manage Your Remote Team of Developers (Publication)

https://www.toptal.com/remote/how-not-to-manage-your-remote-developers

When entering the remote developers’ world, the biggest obstacle that managers must overcome is to change their mindset by accepting that the developer will not be in plain sight, and where they can manage and follow the work being done. This new paradigm requires businesses to implement a number of mechanisms to track progress and avoid a redundant workload. Such mechanisms will help both manager and developer be more productive, which is in everyone’s best interest.
