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.

At we combine the Group Style Inventory with another systems methodology called the TOC Thinking Processes.

The TOC Thinking Processes are a suite of logic trees that provide a roadmap for change.

They guide the team through the decision making process of problem structuring, problem identification, solution building, identification of barriers to be overcome, and implementation of the solution.

The combination of the measurement tools and the TOC Thinking Processes allows teams to develop Strategy and Objectives that will logically improve the level of constructive thinking and behaviour and reduce the reliance of learnt passive defensive and aggressive defensive styles.

From these Strategies and Objectives teams can develop action plans that deliberately create new experiences that will reinforce the new desired behaviour, increase team synergy and provide for better group decision making.
