Why Use Group Styles Inventory™ The Group Styles Inventory (GSI) is the only research-based tool that provides a valid and reliable measure of how people in groups interact with each other and work as a team to solve problems.

OCI

The GSI is an excellent tool for helping teams and groups solve problems more effectively. It’s particularly valuable for team development initiatives such as:

  • measuring and monitoring team performance
  • creating a team environment that encourages innovation and idea-sharing
  • sharpening team members’ analytical skills
  • developing consensus-based decision-making
  • improving the quality and acceptance of group and organisational decisions.

Extensively researched and internationally proven, this survey tool provides group members with a ‘safe’ way to talk about their behaviour and how it affects the group’s performance.

By highlighting factors that are helping or hindering their teamwork, they empower them to change the way they think and behave, leading to better cooperation, communication and consensus, more innovative thinking, and better-quality decisions.

How Group Styles Inventory™ Works?

Group Styles Inventory™

The GSI is designed for both temporary and permanent groups responsible for solving problems and making decisions. It can be used as a continual improvement exercise or when a group is embarking on, halfway through, or has completed a problem-solving process. The GSI has three parts:

  • Teams come together and attempt a problem solving simulation spread across 60-90 mins. This simulation is then scored for productivity and synergy.
  • Individual group members then respond to 72 statements describing teamwork behaviour, such as team effectiveness, solution acceptance, solution quality and team synergy. It takes about 15 minutes.
  • The team members score their surveys and profile their individual and combined results. It takes 10-15 minutes.

Data is collected in an online portal and processed in real-time. Participants receive access to their own results and the team’s; the portal also contains an integrated development guide.

As an accredited Human Synergistics practitioner, we guide the team through their results and facilitate the team to come up with action plans to work on, back at the workplace.
