Group Styles Inventory (GSI)

The Group Styles Inventory (GSI) is a team based measure, which assesses the behaviours observed by team members during a team decision-making session.



Each team member completes the inventory and the combined responses represent a clear profile of the behaviours used by the team in its efforts to achieve quality decisions with high acceptance.

The GSI measures the constructive and defensive elements of group processes with the 12 styles used in the Human Synergistics Circumplex.

Certain group styles are productive and lead to high quality decisions to which members are highly committed. Other group styles are counterproductive and lead to solutions of marginal or poor quality and limited group acceptance.

Used in conjunction with a group problem-solving simulation, the GSI provides significant practical insight into how a group functions, allowing the group to focus its efforts precisely on where improvement is needed.

Unique characteristics of the Group Styles Inventory (GSI)

  • Provides group members with a ‘safe’ way to talk about behaviours within the team and the impact these have on group performance
  • Allows group members to clearly identify what is helping and hindering the team in its efforts – leading to improvement planning for enhance performance
  • Meets rigorous academic and psychometric standards
  • Integrates with the Life Styles Inventory and the Organisational Culture Inventory® (OCI) measures to show the link between individual, group and organisational level behaviours
