Assessing your team's performance can be done with evaluation models that are based on research and theory. The Kirkpatrick model evaluates your team's effectiveness on four levels: reaction, learning, behavior, and results. It helps you measure how the team responds to training, how much they learn, how they apply their learning, and how they contribute to goals. The Tuckman model evaluates your team's effectiveness based on five stages: forming, storming, norming, performing, and adjourning. It helps you measure how the team develops relationships, resolves conflicts, establishes norms, achieves goals, and completes tasks. The Belbin model evaluates your team's effectiveness based on nine roles: plant, resource investigator, coordinator, shaper, monitor evaluator, team worker, implementer, completer finisher, and specialist. This model helps you measure how the team uses skills and personalities to complement each other and balance the team.
