Do not treat nearshore specialists as “contractors” or outsiders, they are part of your team. Invite them to (virtual) social events, make an effort to get to know each individual, share company strategy, et cetera. Make sure they truly feel part of the team!
Communication is the key. There is no such thing as “over-communication” when working with remote or distributed teams. Alignment and transparency about business strategy are critical.
Choose the nearshore partner you can trust. It needs to be a collaboration between parties and not just a “financial agreement”.
