Types of Online Collaboration Tools

Online collaboration tools are divided into two types according to the communication style: synchronous and asynchronous. Synchronous collaboration tools allow two or more employees to work on the same project or page at the same time. In this way, employees can communicate in real time to develop the project and complete the given tasks. Asynchronous collaboration tools do not allow employees to edit projects in real time. Asynchronous collaboration tools are more advantageous for employees with different working schedules. According to Grammarly's research, as the remote or hybrid work culture has increased, employees' use of written communication channels has increased by 18%.

• Save Time and Resources: You can make communication between employees faster by using online collaboration tools instead of emails and chat platforms. 
• Increase Productivity: Online collaboration tools make the work process more straightforward, allowing employees to focus more on important tasks. 
• Improve Communication: Instead of waiting for a response from platforms such as email, employees can communicate in real-time with online collaboration tools.
