The digital-first communication approach has drastically changed the modern workplace, with Slack as the main driver of team collaboration. However, numerous organizations are still experiencing disconnected performance management processes that lead employees to different places other than their daily workflows. 

Data suggests that companies that apply continuous performance management, which is integrated with collaboration platforms, achieve up to 30% of engagement scores and have 19% of voluntary turnover.

Optimizing Slack performance is not just about counting the number of messages or measuring the speed of responses. It means to construct user-friendly workflows where the performance reviews, the provision of feedback, and the development of employees are the natural, automatic processes in the tools that your team members use daily. 

This guide introduces the leading performance review tools with direct Slack integration, helping you create a more unified and effective employee performance management approach.
