Phase Project Work: Team Development Stages and Life Cycle Framework
PMBOK v8 Definition
Project phases are collections of logically related project activities that culminate in the completion of one or more deliverables and/or outcomes. The project team is a set of individuals performing the project’s work who are directly responsible for achieving project objectives, and their development progresses through five stages: Forming, Storming, Norming, Performing, and potentially Adjourning. Teams may skip a stage depending on project context and team maturity.
Why It Matters for the Exam
The Tuckman team development model (Forming, Storming, Norming, Performing) is frequently tested in PMI exam questions about team dynamics, conflict resolution, and leadership styles. Expect situational questions where you must identify which stage a team is in based on behaviors described, or recommend the appropriate management approach for that stage.
Key Points to Remember (for the exam)
- Forming: Team members meet, learn about the project and their formal roles and responsibilities. Members tend to be independent and not open.
- Storming: Team begins addressing project work, technical decisions, and project management approach. Environment becomes counterproductive if members are not collaborative or open to differing ideas.
- Norming: Team members begin working together, adjust work habits and behaviors to support the team. Members learn to trust one another.
- Performing: Teams function as a well-organized unit. This is the most productive stage.
- Key Insight: Teams may skip a stage—this is explicitly stated in PMBOK v8 and commonly tested.
- Project Phase Characteristics: Cost and staffing are low at start, increase as work is carried out, drop rapidly as project or phase ends. Risk and uncertainty are high at start.
- Project Review: An event at end of a phase or project to assess status, evaluate value delivered, and determine readiness to move to next phase or transition to operations.
Typical PMI Exam Example
A project manager notices that team members are arguing about technical approaches and questioning the project management methodology. Several members refuse to accept ideas from others. According to PMBOK v8, which team development stage is the team experiencing? → Storming, because the team is addressing project work and technical decisions, but the environment is becoming counterproductive due to lack of collaboration.
PMI Exam Traps
- Trap: Confusing Storming with Norming → Reality: Storming involves conflict and counterproductive behavior; Norming involves trust-building and behavioral adjustment.
- Trap: Assuming all teams must go through every stage sequentially → Reality: PMBOK v8 explicitly states teams may skip a stage.
- Trap: Thinking team development stages only apply to new teams → Reality: Stages can reoccur when team composition changes or project conditions shift.
- Trap: Confusing "project phase" with "team development stage" → Reality: Project phases relate to deliverables and outcomes; team development stages relate to team behavior and collaboration.
Important PMI Connections
| Related Concept | Relationship Type | Exam Attention Point |
|---|---|---|
| Project Life Cycle | Framework for phases | Team development occurs within project phases; both use sequential, transitional, or overlapping patterns |
| Project Reviews | End-of-phase event | Reviews assess team readiness to move to next phase; team development stage affects review outcomes |
| Project Management Focus Areas | Guides management approach | Leadership style must adapt to team development stage (e.g., directive in Forming, supportive in Performing) |
| Project Team Composition | Input to team development | Team size, composition, and skill level affect which stages occur and how quickly teams progress |
Quick Review Questions
- A project team is functioning as a well-organized unit with minimal supervision. Which Tuckman stage are they in?
- During which stage do team members learn about their formal roles and responsibilities and tend to be independent?
- What does PMBOK v8 say about teams skipping a stage in the development model?
- In a predictive project scenario, how do cost and staffing levels typically behave across project phases?
- What is the purpose of a project review at the end of a phase?
