Overview

TESS 360 looks at how the team functions as a whole. Instead of rating individuals, team members reflect on the group itself—how work is coordinated, how communication flows, and how united the team feels around shared goals. This assessment is useful because it captures the team’s collective view of how it works together. TESS 360 helps organizations see how collaboration, coordination, and shared responsibility are experienced at the team level.

What it assesses

This assessment provides an overall view of patterns that tend to shape:

  • How well the team coordinates work and handles projects
  • How clearly information is shared and understood
  • How responsibilities are distributed and followed through on
  • How aligned the team feels around common goals
  • How day-to-day teamwork affects overall effectiveness

Why professionals use it

Professionals often choose this assessment to capture shared perceptions about how the team functions day to day.

  • Show how the team experiences its own ways of working
  • Highlight strengths that support collaboration and progress
  • Surface shared issues that may be slowing the team down
  • Support more focused team discussions and planning
  • Help teams reflect on how they function together

Where it fits well

  • Team development and improvement: Useful when teams want a clearer picture of how they are working together.
  • After team changes or restructuring: Helps assess how the group is adjusting to new roles or membership.
  • Project follow-up: Useful for reviewing how teamwork influenced outcomes after work is completed.
  • Ongoing team feedback cycles: Supports regular reflection on team effectiveness rather than one-time evaluation.

A helpful professional note

TESS 360 reflects the team shared perceptions at a specific point in time, not a fixed measure of team capability. Feedback can be influenced by recent events, workload, and context. Results are best treated as one data point and used to support reflection, discussion, and improvement rather than judgment.
