Group Styles Inventory (GSI)

GSI measures how people in groups interact and work as a team. It highlights factors that help or hinder teamwork and gives teams a constructive way to talk about behaviour, enabling shifts in how they think and act—leading to better cooperation, communication, consensus, innovation, and decision quality. 

• Intact Teams & Project Teams: Diagnose current working styles and outcomes to inform action.
• Facilitators/Coaches: Run the survey, debrief the Circumplex, and guide team commitments.
• Program/PMO: Set up the survey and manage timelines/report release via the Respondent Portal. 

GSI has two parts: individuals respond to teamwork-behaviour statements (e.g., effectiveness, solution acceptance, solution quality, team synergy), then team members score their surveys and profile both individual and combined (group) results. 

1. Circumplex outputs: Team and individual profiles across the 12 styles grouped into Constructive, Passive/Defensive, and Aggressive/Defensive clusters; raw scores typically range 0–24 per style (6 items each). See the Group Styles Circumplex charts on pages 2–3 of the sample report. 
2. Outcome metrics: Team Effectiveness, Perceived Synergy, Individual Solution Acceptance, Group Commitment, Time Effectiveness, Quality of Solution, and Group Consensus (see the outcomes panel on page 4 and the percentile bars on page 5 of the sample report). 

1. Go to the Respondent Portal: https://idc.human-synergistics.com.au/rp/. Enter your email; create a new account or sign in with your password. New users receive a verification code by email (check Junk if needed). 
2. Find your survey: From the Surveys tab, enter the Survey ID and click Go, or select the listed project if you were pre-added. 
3. After submitting: You’ll return to the portal. Depending on what the facilitator has released, you may see “Processing,” an information message, or buttons to download your individual and/or group report. Use the Reports tab to see all available reports.
4. Interactive Report: Clicking a profile opens the interactive report (item-level detail included once released) where you can toggle between Your GSI Profile and Group GSI Profile.

• Group Styles Circumplex (page 2 of sample report): Shows group profile and per-style raw/percentile scores (0–24 raw). Use it to spot dominant clusters and discuss impact on results.
• Individual Profile (page 3): Each participant’s Circumplex alongside the group’s, highlighting alignment or dissonance. 
• Group Outcomes – Raw Scores (page 4): Seven items plotted; note that Group Commitment and Time Effectiveness are reversed so positive evaluations plot to the right.
• Group Outcomes – Percentiles (page 5): Bars categorize outcomes as high (≥75th), medium (25th–75th), or low (≤25th) vs. norms; Commitment and Time Effectiveness are reversed so higher percentiles signify higher effectiveness. 

Below is an outline that pairs an experiential problem-solving activity with GSI debrief and action planning:

• 8:30 — Objectives, introductions, expectations
• 9:30 — Sub-Arctic Survival activity; immediate GSI “how the team went” debrief
• 10:45 — Score and plot team/individual results; discuss Synergistic Effective Problem Solving; map to Circumplex and LSI links; “what we did well / could improve” reflections
• 12:30 — Lunch
• 1:00 — Leader presents future expectations/demands
• 1:15 — Create Ideal Leader Profile in groups; plot/compare to own
• 2:00 — Most effective styles; “In/Out of the Box”; ETC demo & paired practice
• 3:00 — MBIR example; paired MBIR practice
• 3:45 — Reconvene, reflections
• 4:00 — Check-out: one thought/feeling; one commitment; accountability agreement; 4:30 close

• Report release timing: Group reports appear only after all surveys are submitted and the facilitator releases them in the portal. 
• Interpretation balance: Use both the Circumplex and Outcome metrics; discuss how styles help or hinder specific outcomes (e.g., consensus, solution quality). 
• Normalize the conversation: Emphasize that GSI is designed as a safe way to talk about behaviour and improve teamwork (not to blame individuals).
