Effective collaboration starts with clear communication. Set expectations early, provide comprehensive project briefs, and establish regular check-ins. Use collaboration tools like Slack, Trello, or Jira to streamline communication and task management. It's also beneficial to foster a sense of team inclusivity. Even if they're remote, involve them in team meetings, brainstorming sessions, and even casual team chats. This not only keeps them informed but also integrates them into the company culture, leading to better cohesion and understanding of project goals.
