About This Article
Source information and links for materials cited are provided in the References section.
"Ground rules for a high performing team," by Andy Stuart, was presented at PMI Global Congress 2014–North America in Phoenix, Arizona, and published by the Project Management Institute (PMI) on its website on October 26, 2014. The paper presents a process for developing team ground rules, with an emphasis on building trust, understanding individual behavioral tendencies, establishing a common vision, and aligning team objectives with organizational strategy.
The topic is important, and some of the recommendations offer practical value. However, the paper contains significant problems involving historical accuracy, the interpretation of established research, and scholarly sourcing. The most notable concerns its treatment of Bruce W. Tuckman's team-development model. Stuart explicitly identifies the model as having four stages—Forming, Storming, Norming, and Performing—without acknowledging the fifth stage, Adjourning, which Tuckman and Mary Ann C. Jensen added in their 1977 revision.
The problem is compounded by the paper's failure to cite either of Tuckman's original publications. Instead, it references a secondary webpage discussing the model.
These shortcomings warrant examination, particularly given that the paper was published by PMI, a prominent professional association whose material is used by project management practitioners, educators, and organizations.
1. Incorrect Number of Stages in Tuckman's Team-Development Model
Stuart writes:
“As defined by Tuckman, the team development lifecycle has four stages: Forming, Storming, Norming and Performing.”
That statement is incorrect because it presents the four-stage formulation as the complete model without acknowledging the subsequent addition of a fifth stage.
The historical record is clear:
The 1977 publication explicitly identifies the addition of Adjourning to the model.
Consequently, by the time Stuart presented his paper in 2014, the five-stage formulation had been established in the literature for 37 years.
Describing the 1965 hypothesis as having four stages, and the 1977 update as being inclusive of five stages, is historically accurate. Presenting the model as having only four stages is not.
This is comparable to stating that the United States has 48 states. That number was historically accurate before Alaska and Hawaii joined the Union (both in 1959), but it is not an accurate description today. Accuracy requires recognizing subsequent developments.
A more appropriate formulation would be:
“Bruce W. Tuckman originally proposed a four-stage model of small-group development in 1965. In 1977, Tuckman and Mary Ann C. Jensen revisited the model and added a fifth stage, Adjourning.”
This wording accurately distinguishes the original research from its subsequent revision and credits both contributors.
2. Omission of the Fifth Stage, Adjourning
The problem extends beyond the incorrect four-stage statement. Stuart does not mention Adjourning anywhere in his discussion of Tuckman's model.
This is a substantive omission. Adjourning is not an incidental addition or an informal extension suggested by an unrelated commentator. It was formally incorporated into the model through the 1977 publication by Tuckman and Jensen.
The fifth stage addresses the termination of a group, including the separation and dissolution of its members. It is relevant to organizational and project environments, where teams eventually disband, transition, or otherwise conclude their work.
For example, a project team may disband following successful delivery, cancellation of a project, a change in organizational priorities, or a decision to discontinue an initiative. In each case, the team's termination may involve knowledge transfer, documentation, lessons learned, and the reassignment or release of team members.
The omission is particularly difficult to justify because the 1977 revision was published decades before Stuart's paper. It is an established part of the model's history, not a recent development that might reasonably have escaped notice.
A paper explaining team development and recommending when to establish team ground rules should accurately represent the model it invokes. Leaving out an entire stage makes that representation incomplete.
3. Reliance on a Secondary Source Instead of Original Research
The issue is compounded by the paper's References section.
Rather than citing Tuckman's original research, Stuart lists:
“Tuckman’s stages of team development – Retrieved from A Visit From Coach Tuckman: The Lakers and Team Development.”
This is a secondary source discussing Tuckman's work. It is not either of the original publications.
The two primary sources needed to substantiate the discussion are:
Neither appears in the References section of Stuart's paper.
This is an example of secondary-source reliance: using another author's interpretation or account of original research instead of consulting and citing the original research itself. Depending on the circumstances, this practice can also involve citation laundering or secondary-source distortion.
That distinction is important. A secondary source may summarize, simplify, misinterpret, or omit material from the original research. When an author relies on that intermediary without checking the primary publication, errors can be inherited and reproduced as though they were established facts.
A more appropriate approach would have been to consult and cite both Tuckman's 1965 paper and the 1977 paper coauthored with Jensen. Secondary sources may provide additional context, but they should not substitute for the original research when the original work is available and directly relevant.
Stuart's paper addresses an important topic. Establishing team ground rules collaboratively, building trust, understanding behavioral differences, and aligning team objectives with organizational priorities can all contribute to effective teamwork.
However, the paper's treatment of Tuckman's team-development model and its subsequent expansion by Tuckman and Jensen contains substantive inaccuracies and omissions that fall short of the scholarly rigor expected of a leading professional association.
The problems are substantive. The paper incorrectly presents Tuckman's model as having four stages, omits Adjourning, and relies on a secondary source instead of citing original research.
The first two issues are closely related, but they identify distinct shortcomings. The paper misrepresents the historical development of the model and leaves out an entire stage that Tuckman and Jensen formally incorporated in 1977. The omission and misrepresentation of material information compromise the paper’s accuracy and undermine its credibility. The third issue concerns the failure to consult and cite the original research that would have provided an authoritative basis for the discussion.
The 1977 revision is not obscure or recent research. It was published decades before Stuart's 2014 presentation. The original publications are readily identifiable, and the relevant historical development is unambiguous. There was no reason to present the four-stage formulation as the complete model or to omit the fifth stage.
Authors who discuss established research have a responsibility to consult the original work when making claims about it. Relying on an intermediary account without verifying it against the primary research creates an unnecessary risk of propagating inaccuracies. A reference list that omits the original research while directing readers to a secondary webpage does not meet that responsibility.
There is also an institutional dimension. PMI is a prominent professional association serving the global project management community. Its publications reach practitioners, educators, researchers, and organizations that may reasonably regard PMI-published material as a reliable resource. Publishing and continuing to make material available carries a responsibility to maintain appropriate standards of factual accuracy and scholarly attribution.
The publicly available publication record does not establish what editorial or review procedures were applied to this particular paper. Nevertheless, the deficiencies identified here raise legitimate questions about the quality-control process. An organization of PMI's standing should take such matters seriously, particularly when inaccurate descriptions of established research are disseminated under its name.
The appropriate response would be to correct the historical account, acknowledge Adjourning, and add the missing primary-source references.
Professional credibility depends on more than presenting useful ideas. It also depends on accurately representing research and properly crediting original contributors. On those measures, Stuart's paper requires substantial correction. Absent these corrections, PMI is perpetuating misinformation through its publication and distribution of the paper.

Introduction
"Ground rules for a high performing team," by Andy Stuart, was presented at PMI Global Congress 2014–North America in Phoenix, Arizona, and published by the Project Management Institute (PMI) on its website on October 26, 2014. The paper presents a process for developing team ground rules, with an emphasis on building trust, understanding individual behavioral tendencies, establishing a common vision, and aligning team objectives with organizational strategy.
The topic is important, and some of the recommendations offer practical value. However, the paper contains significant problems involving historical accuracy, the interpretation of established research, and scholarly sourcing. The most notable concerns its treatment of Bruce W. Tuckman's team-development model. Stuart explicitly identifies the model as having four stages—Forming, Storming, Norming, and Performing—without acknowledging the fifth stage, Adjourning, which Tuckman and Mary Ann C. Jensen added in their 1977 revision.
The problem is compounded by the paper's failure to cite either of Tuckman's original publications. Instead, it references a secondary webpage discussing the model.
These shortcomings warrant examination, particularly given that the paper was published by PMI, a prominent professional association whose material is used by project management practitioners, educators, and organizations.
3 Key Issues
1. Incorrect Number of Stages in Tuckman's Team-Development Model
Stuart writes:
“As defined by Tuckman, the team development lifecycle has four stages: Forming, Storming, Norming and Performing.”
That statement is incorrect because it presents the four-stage formulation as the complete model without acknowledging the subsequent addition of a fifth stage.
The historical record is clear:
- 1965: Bruce W. Tuckman published “Developmental Sequence in Small Groups” in Psychological Bulletin. The paper proposed four stages: Forming, Storming, Norming, and Performing.
- 1977: Bruce W. Tuckman and Mary Ann C. Jensen published “Stages of Small-Group Development Revisited” in Group & Organization Studies. The paper noted that, following their review of subsequent research, they added a fifth stage, Adjourning, to the model.
The 1977 publication explicitly identifies the addition of Adjourning to the model.
Consequently, by the time Stuart presented his paper in 2014, the five-stage formulation had been established in the literature for 37 years.
Describing the 1965 hypothesis as having four stages, and the 1977 update as being inclusive of five stages, is historically accurate. Presenting the model as having only four stages is not.
This is comparable to stating that the United States has 48 states. That number was historically accurate before Alaska and Hawaii joined the Union (both in 1959), but it is not an accurate description today. Accuracy requires recognizing subsequent developments.
A more appropriate formulation would be:
“Bruce W. Tuckman originally proposed a four-stage model of small-group development in 1965. In 1977, Tuckman and Mary Ann C. Jensen revisited the model and added a fifth stage, Adjourning.”
This wording accurately distinguishes the original research from its subsequent revision and credits both contributors.
2. Omission of the Fifth Stage, Adjourning
The problem extends beyond the incorrect four-stage statement. Stuart does not mention Adjourning anywhere in his discussion of Tuckman's model.
This is a substantive omission. Adjourning is not an incidental addition or an informal extension suggested by an unrelated commentator. It was formally incorporated into the model through the 1977 publication by Tuckman and Jensen.
The fifth stage addresses the termination of a group, including the separation and dissolution of its members. It is relevant to organizational and project environments, where teams eventually disband, transition, or otherwise conclude their work.
For example, a project team may disband following successful delivery, cancellation of a project, a change in organizational priorities, or a decision to discontinue an initiative. In each case, the team's termination may involve knowledge transfer, documentation, lessons learned, and the reassignment or release of team members.
The omission is particularly difficult to justify because the 1977 revision was published decades before Stuart's paper. It is an established part of the model's history, not a recent development that might reasonably have escaped notice.
A paper explaining team development and recommending when to establish team ground rules should accurately represent the model it invokes. Leaving out an entire stage makes that representation incomplete.
3. Reliance on a Secondary Source Instead of Original Research
The issue is compounded by the paper's References section.
Rather than citing Tuckman's original research, Stuart lists:
“Tuckman’s stages of team development – Retrieved from A Visit From Coach Tuckman: The Lakers and Team Development.”
This is a secondary source discussing Tuckman's work. It is not either of the original publications.
The two primary sources needed to substantiate the discussion are:
- Tuckman, B. W. (1965). “Developmental Sequence in Small Groups.” Psychological Bulletin, 63(6), 384–399.
- Tuckman, B. W., & Jensen, M. A. C. (1977). “Stages of Small-Group Development Revisited.” Group & Organization Studies, 2(4), 419–427.
Neither appears in the References section of Stuart's paper.
This is an example of secondary-source reliance: using another author's interpretation or account of original research instead of consulting and citing the original research itself. Depending on the circumstances, this practice can also involve citation laundering or secondary-source distortion.
That distinction is important. A secondary source may summarize, simplify, misinterpret, or omit material from the original research. When an author relies on that intermediary without checking the primary publication, errors can be inherited and reproduced as though they were established facts.
A more appropriate approach would have been to consult and cite both Tuckman's 1965 paper and the 1977 paper coauthored with Jensen. Secondary sources may provide additional context, but they should not substitute for the original research when the original work is available and directly relevant.
Conclusion
Stuart's paper addresses an important topic. Establishing team ground rules collaboratively, building trust, understanding behavioral differences, and aligning team objectives with organizational priorities can all contribute to effective teamwork.
However, the paper's treatment of Tuckman's team-development model and its subsequent expansion by Tuckman and Jensen contains substantive inaccuracies and omissions that fall short of the scholarly rigor expected of a leading professional association.
The problems are substantive. The paper incorrectly presents Tuckman's model as having four stages, omits Adjourning, and relies on a secondary source instead of citing original research.
The first two issues are closely related, but they identify distinct shortcomings. The paper misrepresents the historical development of the model and leaves out an entire stage that Tuckman and Jensen formally incorporated in 1977. The omission and misrepresentation of material information compromise the paper’s accuracy and undermine its credibility. The third issue concerns the failure to consult and cite the original research that would have provided an authoritative basis for the discussion.
The 1977 revision is not obscure or recent research. It was published decades before Stuart's 2014 presentation. The original publications are readily identifiable, and the relevant historical development is unambiguous. There was no reason to present the four-stage formulation as the complete model or to omit the fifth stage.
Authors who discuss established research have a responsibility to consult the original work when making claims about it. Relying on an intermediary account without verifying it against the primary research creates an unnecessary risk of propagating inaccuracies. A reference list that omits the original research while directing readers to a secondary webpage does not meet that responsibility.
There is also an institutional dimension. PMI is a prominent professional association serving the global project management community. Its publications reach practitioners, educators, researchers, and organizations that may reasonably regard PMI-published material as a reliable resource. Publishing and continuing to make material available carries a responsibility to maintain appropriate standards of factual accuracy and scholarly attribution.
The publicly available publication record does not establish what editorial or review procedures were applied to this particular paper. Nevertheless, the deficiencies identified here raise legitimate questions about the quality-control process. An organization of PMI's standing should take such matters seriously, particularly when inaccurate descriptions of established research are disseminated under its name.
The appropriate response would be to correct the historical account, acknowledge Adjourning, and add the missing primary-source references.
Professional credibility depends on more than presenting useful ideas. It also depends on accurately representing research and properly crediting original contributors. On those measures, Stuart's paper requires substantial correction. Absent these corrections, PMI is perpetuating misinformation through its publication and distribution of the paper.

About This Critical Analysis
This article examines Andy Stuart's discussion of team development and team ground rules, with particular attention to its treatment of Tuckman's model and its use of secondary sources. The assessment draws directly on the original 1965 and 1977 publications by Tuckman and Tuckman and Jensen, respectively, rather than relying on second-hand interpretations or accounts that may misrepresent the original research.
