Final answer:
The Tuckman ladder describes five stages of team development: Forming, Storming, Norming, Performing, and Adjourning. The student's question references different development theories, which are not related to Tuckman's stages directly.
Step-by-step explanation:
The question refers to the Tuckman ladder, which is a model describing five stages of team development. However, the references provided don't specifically mention Tuckman's stages, which are Forming, Storming, Norming, Performing, and Adjourning. Instead, different development theories are mentioned, such as Rostow's economic development stages, the demographic transition model, the process of design development in teams, theories of family development, and types of teams in an organization.
It is important to clarify that the correct descriptions of Tuckman's stages are as follows:
- Forming: Team members get to know each other and understand the task at hand, but roles are not yet established.
- Storming: Team members confront each other as they vie for roles and the team's mission, structure, and future are clarified.
- Norming: The team establishes agreements and roles are accepted. Cohesion grows, and unity is strong.
- Performing: The team works efficiently and functionally towards achieving its goals.
- Adjourning: The team completes the task and disbands. This stage is sometimes also referred to as Mourning.
These stages are critical in understanding how teams develop and evolve, particularly in a business or educational context where collaboration is key.
