GC Index: Understand How Leaders and Teams Create Impact
Use GC Index with EvolunIQ to understand how leaders and teams create impact, strengthen contribution patterns and improve leadership-team effectiveness.
Discuss GC Index for a leadership teamBeyond style — understanding how people create impact.
Most assessment tools focus on personality traits or leadership style. The GC Index® takes a different starting point: how does this person prefer to make an impact? The GC Index® identifies five impact roles — each representing a distinct orientation toward contribution. No role is superior; each is essential. The diagnostic creates a shared language for discussing how people and teams create value, and where complementarity or gaps exist. EvolunIQ uses GC Index as a certified GC Partner and delivery practitioner — not as the instrument's owner.
The profile is the starting point. The value is in the facilitated team work.
EvolunIQ uses GC Index to build team insight, contribution awareness, and role clarity — informing how a team is composed, facilitating honest discussion about impact and workload, and translating the diagnostic into team development and live business application, not a standalone report.

Most leadership teams are not consciously composed.
Senior leadership teams are typically assembled based on functional expertise or seniority — not on how individuals create impact or where they naturally contribute. The result: teams over-indexed toward certain roles and chronically under-resourced in others.
A team with five Implementers and no Game Changer will execute well but struggle to innovate. These gaps are invisible without a shared diagnostic language.
GC Index gives leadership teams a shared, non-judgmental language for understanding how each member contributes — and where the collective is strong or exposed, enabling intentional team design and more honest conversations about roles and workload.
Used within a facilitated programme, it accelerates role clarity, reduces friction, and helps leaders draw on the complementary contributions of others.
Integrated into facilitation and leadership programmes.
Before designing a facilitation format or leadership programme, GC Index is used to map the impact-role profile of the participating team — informing the design so it draws on the team's existing strengths while surfacing under-represented orientations.
Within a leadership-development programme, GC Index supports the early phase of individual coaching — helping each executive understand their natural impact orientation relative to peers, and building a foundation for more conscious role behaviour.
In select engagements, EvolunIQ delivers formally structured solutions built on GC Index methodology, covering areas such as M&A integration, team performance, and executive coaching — part of EvolunIQ's GC Partner accreditation.
A core input into how EvolunIQ develops leadership teams.
GC Index supports leadership-team development directly — collective leadership, contribution patterns, role clarity, decision-making, accountability, collaboration, operating rhythm, and the deliberate use of complementary strengths across the team.
Also embedded in broader leadership-development work.
Where appropriate, GC Index findings support individual reflection, leadership contribution, role clarity, coaching focus, and development priorities within a wider leadership-development programme.
Individual results can sharpen a coaching conversation.
Where relevant, an individual's GC Index results can support reflection, awareness of their leadership contribution, role clarity, and coaching focus — informing development priorities within an executive coaching engagement.
Useful when a leadership team itself is changing.
GC Index is particularly useful for newly formed leadership teams, teams integrating new leaders or functions, and teams navigating reorganisation or transformation — where understanding how the reshaped team creates impact is a practical starting point, not a general M&A advisory exercise.
One of two instruments EvolunIQ integrates into development.
GC Index is one of two certified assessment suites EvolunIQ integrates into leadership development, alongside the Leadership Circle Profile®. The Leadership Assessments hub explains how both fit into the broader measure-to-development pathway.
