Bruce Tuckman: Group Development

Bruce Tuckman developed a model of group development which is among the most viewed management models on The Management Pocketblog. We cannot wait any longer: we must take a look at his life and work with a wider perspective.

Bruce Tuckman

 

Brief Biography

Bruce Tuckman was born and grew up in New York, gaining his bachelor’s degree in psychology from the Renesselaer Polytechnic Institute in 1960, and his MA and PhD from Princeton, in 1962 and 1963 respectively.

From Princeton, he joined the Naval Medical Institute in Bethesda, Maryland, as a research psychologist. Here, he joined a group of researchers that was researching the the behaviours of small groups, thinking about getting the best team working on small crewed naval vessels. His supervisor gave him a stack of fifty research papers, telling him to see what he could make of them. His analysis resulted in the developmental sequence that was to make him famous:

  1. Forming – orientation, relationship building
  2. Storming – conflict
  3. Norming – developing cohesion and behavioural norms
  4. Performing – team inter-dependence and collaboration

Tuckman subsequently acknowledged that it was the choice of rhyming names for the stages that he used in his published paper (1965) ‘which probably account for the paper’s popularity’. The terms are certainly memorable and evocative.

From 1965, when he moved to his first academic post, at Rutgers, Tuckman started to focus on Educational Pyschology. In 1978, he moved to City University of New York and then to Florida State University in 1983. In 1998, he moved to Ohio State University, as Professor of Educational Psychology, where he remained until his retirement.

Developmental Sequence in Small Groups

The group development model for which Tuckman is best-known has been well covered in the Mangement Pocketblog already; so much so that we took the unusual step of creating a portal blog to guide readers to the various articles, at: Bruce Tuckman’s Group Development Model. You can also read Tuckman’s original paper, Developmental Sequence in Small Groups.

In 1977, Tuckman was invited to review his original work and, with Mary Ann Jensen (at the time a Doctoral student at Rutgers, with Tuckman, and now a psychologist in private practice in Princeton, New Jersey), produced a review paper (Stages of Small-Group Development Revisited) that validated the original work, and added a fifth stage, Adjourning, ‘for which a perfect rhyme could not be found’ said Tuckman. Many practitioners (this author included) prefer to use the term ‘mourning’ – not because it rhymes, but because it reminds us of the emotional impact of separation and therefore of the role of the team leader in ensuring the team acknowledges the loss.

Procrastination

Tuckman’s work on procrastination looks excellent. I was going to look it up but…

As an educational psychologist, most of Tuckman’s work is of limited interest to a management audience. But one topic stood out for me: the bane of many managers’ lives… procrastination. We all do it.

In 1991, while Professor of Educational Psychology at Florida State Univesity, Tuckman published a self evaluation tool to measure tendency to procrastinate. This was a core part of his research into students’ self-motivation in studying. This became a a key plank in much later research which he applied very directly at Ohio State University, where he founded the University’s Dennis Learning Center. They still teach workshops and courses based on Tuckman’s research. All the research related to the learning centre listed on its website is Tuckman’s.

Here’s the research paper that caught my eye: at the American Psychological Association meeting in 2002, Tuckman presented a paper that showed how procrastinators get significantly poorer grades in class. What I wonder is this: is it reasonable to generalise that result to the workplace? I suspect it is.

The message would be clear: ‘just get on with it!’

Kenneth Blanchard: Management Storyteller

It was tempting to describe Ken Blanchard as a simplifier, because that’s what he has done throughout his career; simplify the skills of management. But that is not the essence of what he does. He starts by telling a story and it is that process that both cuts away extraneous theory and also renders his ideas easy to access. Ken Blanchard has turned management theory into a successful training business to a degree that no one else has achieved.

Ken Blanchard

Short Biography

Kenneth Hartley Blanchard was born in New Jersey in 1931 and grew up in New York. He attended Cornell and Colgate Universities, gaining a BA in Government and Philosophy, an MA in Sociology and Counselling, and a PhD in Education Administration and Leadership, in 1967. From there, he went to Ohio University to become an Assistant Dean. Here, he met collaborator, Paul Hersey.

Hersey had been developing a strong model of leadership, based on his industrial experiences before entering academia in 1966, incorporating ideas from researchers like Fiedler, and Blake and Mouton. The pair worked together on a book, Management of Organisational Behaviour, that was published in 1967 and is now in its tenth edition (2012). This book included a model, then called ‘a lifecycle theory of leadership’ but now better known as Situational Leadership. It was not the first situational theory of leadership (see the earlier Pocketblog article: ‘Situational Leadership‘) but it rapidly became the best known.

In 1979, while a professor of organisational behaviour and leadership at the University of Massachusetts, Amherst, he and Hersey agreed to split and Blanchard formed a company called Blanchard Training and Development – that was later (1998) renamed as The Ken Blanchard Companies and is today one of the most successful international businesses of its kind. In that year too, he published his own model of Situational Leadership: Situational Leadership II.

The following year, he was introduced to a psychologist called Spencer Johnson, with whom he rapidly collaborated to write a short book on management, in the form of a fable-like story. They self-published ‘The One Minute Manager‘ in 1980, and it was subsequently published by Morrow in 1982. It has become the kind of best-seller that truly justifies the title: the cover simply proclaims ‘multi-million’.

This became the start of an industry with subsequent collaborations with different authors – the first handful bearing the ‘One Minute Manger brand’ – appearing every few years. Most follow the format of a younger manager seeking the wisdom of an older, more experienced teacher.

Notable contributions (and personal favourites mixed in) include:

Putting the One Minute Manager to Work (1983)

Leadership and the One Minute Manager (1985)

The One Minute Manager Meets the Monkey (1989)

The One Minute Manager Builds High Performing Teams (1990)

Raving Fans : A Revolutionary Approach to Customer Service (1993)

Gung Ho!: How To Motivate People In Any Organization (1998)

Blanchard’s Contribution

Blanchard’s contribution has been to systematise the skills of management and to explain them extremely clearly. Many British readers find the folksy fable style of his books not to their taste, but the fact is that they use simple language and compelling acronyms to make management techniques accessible and memorable.

The original One Minute Manager sets out just three simple tasks in management: one minute goal setting, to clarify what I expect of you, one minute praisings, to recognise progress and performance, and one minute reprimands, to show where you are going wrong.

Putting the One Minute Manager to Work extends this, looking at the management ABC of Activators (what a manager must do to set you up to succeed), Behaviours (your performance) and Consequences (how the manager responds to you with with support and feedback).

Leadership and the One Minute Manager introduces Blanchard’s own view of situational leadership  using the OMM format, which he later extended, in The One Minute Manager Builds High Performing Teams to leading teams. This book creates a neat merger of the situational leadership model with Bruce Tuckman’s model of group formation.

One of Blanchard’s most successful collaborations was with William Oncken Jr (and Hal Burrows), in The One Minute Manager Meets the Monkey. This presents a simple metaphor (the Monkey) for the problems managers accept from their colleagues and team members. It is a powerful articulation of the processes of good delegation and effective management of workload.

In the 1990s, Blanchard wrote four books with Sheldon Bowles, of which my favourites are Gung Ho! and High Five! (2001 – now out of print – about team working). 2000’s Big Bucks! (also out of print) is about making money. The exclamation mark in the four titles is indicative of the amplified style of writing, but all were turned into successful training programmes (not all of which persist, I think).

In summary…

There are many other books as well, some still available. Blanchard is a prodigious collaborator and his company is hugely successful in training managers across the world. I don’t think he will ever be seen as a great and innovative thinker, but without a doubt, he has a talent for tapping into oher people’s ideas and making them highly accessible, from Paul Hersey down to more recent collaborations with Don Shula (Everyone’s a Coach), Colleen Barrett from Southwest Airlines (Lead with LUV), and Garry Ridge, president of WD-40 Company (Helping People Win at Work).

Forming, Storming, Norming: The Tuckman Model of Group and Team Development

The Management Pocketbooks Pocket Correspondence Course

This is part of an extended management course. You can dip into it, or follow the course from the start. If you do that, you may want a course notebook, for the exercises and any notes you want to make.


‘How do new groups of people develop into
effective teams?’

Bruce Tuckman developed the best known and most widely used answer to this question in the early 1960s. Working for the US Navy, he reviewed a wide range of group dynamics research, to identify a sequence of discrete stages that described the findings of most of the studies.

Tuckman himself ascribes the success of his model over other, later models, to the catchy labels he created for the stages.

Tuckman Group Development Model

1. Forming

When a group first comes together, people are keen to get on with the task at hand, but have little idea what is expected of them. In building relationships, they start with the superficial dialogue familiar to anyone who has arrived in a room full of unfamiliar people. As a team leader, focus on giving people work they can get on with and, at the same time, get to know their colleagues. Tuckman referred to this as the forming stage.

2. Storming

People are social creatures, and we need to assert ourselves, find our allies, and make a niche for ourselves. In the next stage, storming, the group turns inward, focusing on relationship building. Conflicts arise as, like hens in the farmyard, we each seek our place in the pecking order. The group may also start to challenge your leadership so, while you keep them focused on work, you need to assert your leadership and provide support to individual team members.

3. Norming

Following the intensely social storming phase, we withdraw into task-focused activities. We hunker down and get on with the work. The group is now more cohesive, focusing on creating procedures, fulfilling defined roles and making progress. This is the norming stage, and it is often very productive. Because people know what their role is now, focus your leadership on creating links between team members and establishing routines and team habits..

4. Performing

As the quality and depth of relationships build, the group reaches its final stage, performing. Group members support each other in their tasks and show greater behavioural flexibility. The group now feels like a team, with individuals stepping into leadership roles as their capabilities and interests dictate. Your leadership can be very subtle, focused on maintaining the productive environment in which the team can thrive, providing them with the information and resources they need, and protecting the team from disruptive interruptions and distractions.

5. Adjourning

Two decades later, in 1977, Tuckman collaborated with Mary Ann Jensen in reviewing further research studies. As well as endorsing his earlier model, their analysis suggested a fifth stage ‘for which the perfect rhyme could not be found’ in Tuckman’s own words.

They called this stage adjourning, although many authors (including me) prefer the term ‘mourning’. As the group separates, there is a palpable sense of loss. The joy of working successfully with valued colleagues is important to us and we mourn its loss. Like in the case of  ‘real’ mourning, you should make time for your team to reflect on the transition and celebrate the past.

Additional Phases

Trainers and writers have introduced additional phases to the model, which each have their value. Two of these, the ‘yawning’ stage and the ‘transforming’ stage have been covered in earlier Pocketblogs:

Critique

Tuckman’s model was not based on primary research and has been criticised for its linear nature and its discrete stages. Despite this, it accords well with people’s experience and has been applied in a number of related formulations.

As a manager, use the model to understand the evolution of your team, and in interpreting what happens among the groups with which you work.

Backwards and Forwards

Pocketblog comes out on Tuesdays, which means that this year, it coincides with both Christmas Day and New Year’s Day.  Which means that there will be a short hiatus before the next edition.

But never fear – I shall be busy.  I will be preparing for next year’s exciting new project.  More about that later.  But first…

The Best of 2012

As before, here is a selection of my own favourite Pocketblogs from 2012.

Early in the year, we did two blogs about Emotional Intelligence: ‘There’s more to Emotional Intelligence than Daniel Goleman’ and then offered practical tips to ‘Boost your EQ’.

Emotional Intelligence

In this Jubilee year, we let you into The Management Secrets of Queen Elizabeth II.  Sadly, advance orders for the Modern Monarch’s Pocketbook have been disappointing (we just received our third, with the same address as the last) and we are holding back on publication until orders pick up.

The Modern Monarch's Pocketbook

Another big event for us was the launch of our Management Pocketblog 100 Day Challenge.  We know (from orders) that some of you took it up.  Please do tell us (on the blog page comments) about your experiences.  If you have not yet, it is not too late to take up the challenge.

The Management Pocketblog 100 Day Challenge

We were able to offer readers insightful business and management tips from to impeccable sources this year.  In ‘What matters today, in Business and Management?’ we extracted tips from Time Magazine’s 2012 100 Most Influential People in the World.  In ‘The Oracle of Omaha’, we took guidance from some of Warren Buffet’s top CEOs.

Our three-part series: ‘The New Manager’s Guide to Interviewing’ will be a helpful resource if you are new to this role.  It covered:

  1. Preparing the Ground
    Increase your chances of success well before the interview
  2. Getting it Right
    Hints and advice for conducting and effective interviews
  3. Polishing your Process
    Tips and tricks of the trade

And, for people on the receiving end, we wrote ‘Seven Ways to Interview Well’ just for you.  If you want to stick with your current job, but spice it up a little bit and renew your motivation, try ‘Same Job: New Job’.

Edward de Bono's Six Thinking Hats

Closest to my own heart were:

Our three-part series about dealing with poor performance in staff, ‘Let’s sort out poor performance’, parts:

          1. Infrastructure
          2. Turnaround
          3. The Alternative

These followed on from two blogs, ‘What is Performance Management?’, and ‘The Root of the Issue: Dealing with Poor Performance’.

Bruce Tuckman: Group Development model...  forming - storming - norming - performing - adjourningOur blogs about Bruce Tuckman’s model of Group Development (Forming-Storming-Norming-Performing) continue to be the most heavily read.  In February, we provided a link to all four of them.

.

And finally…  Pocketblog honoured two sad losses this year: Neil Armstrong, the astonishingly humble all-American/all-global hero; and Stephen Covey, who wrote one of the very best of the best personal effectiveness book: The Seven Habits of Highly Effective People.

Neil ArmstrongStephen Covey


Coming Next Year

Pocketblog is nearly 3 years old (we started on 23 February 2010) and has chalked up over 150 posts to date.  It’s time for a little refresh.  So 2013 will see a new style of Pocketblog.  Not a radical departure: more of a shift in emphasis.

Next year, we’ll be presenting our Management Pocket-Correspondence Course.  Over the course of the year, we’ll be blogging about the full range of management skills in a structured way.  Why not Subscribe to the Blog by email (towards the top of the column to the right of this) to receive them all in your inbox.

Until then…

From everyone at Management Pocketbooks…

Have a very merry Christmas,
and a happy and healthy New Year.

Tuckman Plus, Part 2: Transforming

Towards the end of 2011, we looked at how teams can get bored and suggested a useful extra phase to the familiar Tuckman Model of group development: forming, storming, norming and performing.

As we start a new year, it seems an opportune moment to introduce another phase: Transforming.

Transforming

Tuckman Transforming Phase

As teams reach maturity, it is increasingly common that they do not simply adjourn at the end of their project.  More frequently, the team re-tasked with a new role.  Some members may move on and new people may join, but just like Murphy’s apocryphal pickaxe*, it is still essentially the same team.

Yet it is different: it has changed.  I hypothesise a new phase: Transforming.

Tuckman Model extended to include Transforming Phase

When people leave, new people join, and the team has a new role, it is unlikely to easily remain in the Performing stage.

Perhaps a new member joins and people get their heads down, get on with their work, and figure out how to incorporate Mr or Ms Newbie into the team.  This feels a little like Norming.

Perhaps the new person has a significant role.  People may compete with one another to influence them.  Or maybe, someone significant leaves and two or three members of the team compete for a promotion to fill their place.  These feel a little like Storming.

Perhaps there is a big change in personnel or the role of the team shifts to a completely new project.  Most team members feel pretty uncertain about what’s expected of them and who their new colleagues are.  These feel a lot like Forming.

So Here is the Deal

When a change happens in your team, it is likely to transform.  Detect the extent of the change, and adapt your leadership style to accommodate the new dynamic.  If you continue to manage your team as if it were still in the Performing stage, then you will delay the team’s return to true performing status.

Happy New Year, and many
Prosperous Transformations,
from all of us here at
Management Pocketbooks

* Murphy’s Pickaxe

‘I’ve had this same pickaxe for 40 years,’ says Murphy; ‘it’s had seven handles and three heads, and I love it.’

12 Blogs for Christmas

Holly&Ivy

This has been a great year for the Pocketblog, seeing reading figures rise substantially and reaching the milestone of our 100th blog posting.

So, with Christmas coming at the end of the week, let’s do a round-up of some personal favourites from among this year’s Pocketblogs.

Here is something for each of the twelve days.  Enjoy!

1. Start as you mean to go on: Happiness

After some New Year’s Resolutions to start the year off, we dived into the subject of Happiness, with ‘Happiness – as simple as ABC?’ about Albert Ellis’s Rational Emotive Behavior Therapy – the fore-runner of CBT.

2. … and Start Topical

We then moved into a subject that was much in the news in February; and still is.  With ‘Bankers’ Bonuses and Brain Biology’, we looked at recent neuroscience and how that relates to Adams’ Equity Theory.

3. Generations

In February too, I wrote two blogs about sociological ‘Generations X, Y & Z’ and ‘Generation Y at work’.  I followed this up by another about what comes ‘After Generation Y?’.

4. The Gemba

In May, inspiration waned for a week, so where did I go to find it?  ‘The Gemba’.  I got it back, and later that month, got idealistic in ‘Reciprocity and Expectation’ looking at the Pay it Forward ideal and the realities of Game Theory.

5. Why do we do what we do?

In the first of two blogs on how to predict human behaviour, I looked at ‘How to Understand your Toddler’ (mine actually) and Icek Ajzen’s Theory of Planned Behaviour.  Later in the year, in ‘Predicting Behaviour’, I looked at whether a simple equation (hypothesised by Kurt Lewin) could predict all behaviour.

6. One of the Best Business Books of the Year

… according to the Journal Strategy & Business is Richard Rumelt’s Good Strategy/Bad Strategy: The difference and why it matters.  In ‘What Makes a Good Business Strategy’ we looked at some of his ideas.

7. The Apprentice

This year, I have been a big fan of both series and have written my own episode by episode analysis of both The Apprentice and Young Apprentice.  I also did one blog on each for Pocketblog: ‘The Apprentice and Five Levels of Leadership’ and, for Young Apprentice, ‘Decision Failure’.

8. Drucker Triptych

Has any one individual been as influential in establishing management as a pragmatic academic discipline as Peter Drucker?  To recognise his various achievements, I wrote a triptych of blogs over the summer:

  1. The Man who Invented Management
  2. Management by Objectives
  3. R.I.P. Corporate Clone: Arise Insightful Executive

And one of Drucker’s direct contemporaries was W Edwards Deming, so I also took a look at ‘Demings’ System of Profound Knowledge’.

9. Crazy Times

Will history look on Tom Peters with the respect that it holds for Drucker and Deming?  Who knows?  But without a doubt, Peters has been influential, insightful and provocative for thirty years or more, and I am sure many of his ideas will survive.  In ‘Crazy Times Again’, I drew a line from FW Taylor (father of ‘Scientific Management’) to Peters.

10. The Circle Chart

In ‘Going Round in Circles’ I returned to management models and one of my all time favourites: Fisher and Ury’s Circle Chart. I applied it to problem solving rather than, as they did, to negotiation.

Fisher and Ury are experts on conflict resolution, as is Morton Deutsch. In ‘Conflict: As simple as AEIOU’, I looked at a fabulously simple conflict resolution model that originated in Deutsch’s International Centre for Cooperation and Conflict Resolution.

11. Two Notable Events

Two notable events made the autumn memorable for Pocketblog: one sad and one happy.

  1. In ‘A Bigger Bite’ we marked Steve Jobs’ passing
  2. With ‘Three ways to get it wrong’, we marked our hundredth blog, by looking at one of the towering social psychologists of today, Daniel Kahneman

12. And finally, our most popular topic

Tuckman’s model for group formation has proved to be our most popular topic by far this year.  We have returned to it three times, each time looking at a particular facet:

  1. ‘Swift Trust: Why some teams don’t Storm’
  2. ‘Team Performance Beyond Tuckman’
  3. ‘Tuckman Plus’ is the first of two posts.  It is the last topic post of 2011 and its companion (‘Part 2: Transforming’) will be the first of 2012

So here’s the deal

  • Have a very merry and peaceful Christmas.
  • Have a very happy and healthy New Year.
  • Be good, have fun, stay safe, and prosper.

From all at Management Pocketbooks,
our colleagues at Teacher’s Pocketbooks too,
and from me particularly.

Tuckman Plus

The conclusions in Bruce Tuckman’s ‘Developmental sequence in small groups’ are among the best known management models.  In it, Tuckman proposed that groups go through four stages of development: forming, storming, norming and performing.

Later, he and Mary Ann Jensen wrote a follow-up article, ‘Stages of small group development revisited’, in which they proposed a fifth stage, adjourning.  We summarised these stages earlier this year, and looked at why teams don’t always go through the storming phase.

The Tuckman Group Development Lifecycle model: forming, storming, norming, performing and adjourning

Critical Review

Tuckman and Jensen’s critical review in 1977 was just the first re-analysis of Tuckman’s original 1965 paper.  As recently as 201, there was a wide review article: ‘40 years of storming: a historical review of Tuckman’s model of small group development’ by Denise Bonebright, a graduate student at the University of Minnesota.  In it, Ms Bonebright concludes that there are new theories that are ‘exponentially broader and deeper than Tuckman’s original model. They provide detailed discussion of many aspects of group dynamics from forming through adjourning.’

These theories examine a range of other factors, and yet they do not

‘provide the same breadth of application. HRD scholars and practitioners can learn something from a model that has proved valuable for almost 45 years. The utility of providing a simple, accessible starting point for conversations about key issues of group dynamics has not diminished.’

Can we extend Tuckman’s Model?

There are two principal extensions to Tuckman’s model that give valuable insights, yet do not add unnecessarily to its complexity.  We will look at the more sophisticated early in the new year, and tackle the simpler, commoner one here.

Yawning

Are you getting tired at the end of a long year?  Is your team getting stale and bored?

Tuckman Group Formation - Yawning Phase

A lot of management trainers add an extra phase beyond performing: ‘yawning’.  This recognises that a team, once formed and into performing stage, can become stale.  It is a teaching aid as much as an extension of the  model, to highlight the importance for a team leader to keep the team fresh and challenged – in both the task and relationships dimensions – if you are to maintain high performance.

It is also a reminder that, if your team slips from its high performance levels, this may be what is happening.

Team Performance Beyond Tuckman

The Tuckman Model of group development is well-known and provides much insight into how a group of individuals evolves into a high performing team. It’s four/five stages form a mantra for many managers who have enjoyed learning about the model at a training event. They have the huge merit of being easy to remember – because they rhyme (perhaps a lesson to any model builder!

Forming – Storming – Norming – Performing – Mourning

Beyond Tuckman

But there are other models – not least because Tuckman’s model is not subject to copyright. One of the best is the Drexler/Sibbet Team Performance Model, which belongs to The Grove Consultants International. It is widely used in association with their Team Performance Inventory, and as a support to their Graphic Facilitation Pocess.

The Drexler/Sibbet Team Performance ModelThe illustration below is a simplified version. For the full version of the chart, you should refer to the Grove’s website, as it is a protected model.

The Drexler/Sibbet Team Performance Model

What I like about this model is firstly, that it identifies the team issues that are resolved at each stage, and also those that are left un-resolved. Secondly, I like the way that, what in Tuckman is a single stage – ‘Norming’ – is dissected into three components here: Goal clarification, commitment and implementation.

My interpretation is that Goal Clarification starts, for Tuckman, in the Storming phase, but only truly resolves in Norming. Likewise, the process of implementation starts in the Norming stage and continues in Performing. Drexler and Sibbet go beyond Tuckman’s term, ‘Performing’ and use the term ‘High Performance’.

An Historical Perspective

While researching this, I found an article by David Sibbet, in which he describes the genesis of the model. Here is an extract:

‘In early 1980 I began working with my colleague Allan Drexler on a formal model for teams called the Drexler/Sibbet Team Performance; System. Earlier research by Allan had generated a simple, four-step model that mirrored the first four stages in process theory. I argued that the model needed to be extended to explain not only the “creating” stages but also the “sustaining stages.” Allan was very experienced with business teams. I applied process theory and eight years, and as many versions later, our Drexler/Sibbet Team Performance™ Model (TPM) has become the standard in the field and used worldwide.’

Also on the same website is another interesting model that David Sibbet had a hand in, The Sibbet/Le Saget Stages of Organization model.

So here’s the deal

The Tuckman Model is excellent – it explains and predicts much. But it is not the only model of team development. We can learn much from the comparisons between different models of the same phenomena. Each will emphasise different aspects, and bring new insights.
