Let's see what do we have on the official IBM blog:

An IBM-convened panel at SIOP 2017 explored the benefits and challenges of remote working. With perspectives from academia as well as public and private sectors, the consistent message was that teleworking works, and that associated challenges can be managed with careful planning and communication.
Academic research from the University of Guelph in Canada, highlighted the importance of using communication channels that attempted to offer some similar benefits of co-location, for example using video conferencing over email or instant messaging.
One challenge of running a virtual team was identified as having to accommodate different time zones, working hours and job characteristics. However, the panellists concluded that, in practice, the relationship between the manager and the employee, rather than strict policies, ends up determining the best way of managing telework. And it was stressed that the team focus should really be on how best to get the job done.
