Book summary “The whole brain business book”: summary

Introduction

You often struggle with teams that fail to innovate, communicate poorly, or resist strategic change. This friction happens because conventional management relies on a narrow slice of human intelligence.

Ned Herrmann presents the Whole Brain Model in The Whole Brain Business Book to solve this limitation. The central idea is that you can optimize business performance by understanding and leveraging cognitive diversity across four distinct thinking quadrants.

The book is structured into eight parts that guide you from neurological foundations to organizational strategy. You learn how to map thinking preferences, manage diverse teams, align leadership styles, and navigate change.

The book answers several key questions:

• How do you measure your personal thinking preferences?
• Why do homogeneous teams struggle with complex problem-solving?
• How can you adapt your communication to reach different cognitive types?
• What steps ensure strategic alignment across an entire enterprise?

1. The Whole Brain Model Foundation

Every business operates on thinking. Optimizing how you think is the fundamental key to improving performance and results in a rapidly changing world.

The brain operates as an interconnected whole, and the Whole Brain Model organizes thinking preferences into four specialized quadrants.

Leading organizations such as the U.S. Naval Command, IBM, Microsoft Game Studio, and Brown-Forman apply Whole Brain Thinking to improve mentoring, global leadership development, video game creation, and marketing. Nine out of ten of the Fortune 100 have applied the system. Thirty years of research stand behind these concepts.

The Brain Research Foundation

The popular left-brain/right-brain dichotomy is an oversimplification. It fails to accurately describe how the brain actually functions as an interconnected whole. Early research by Roger Sperry proved that hemispheres are specialized. However, the exclusive focus on a left/right split ignores other critical systems such as the limbic system, as highlighted by Paul MacLean's triune brain model.

Modern technological advances and large-scale initiatives continue to confirm the existence of specialized brain regions. Since the first edition of the book in 1996, diagnostic tools, the Whole Brain Catalog, the Human Connectome Project, and the BRAIN Initiative have expanded understanding of neural pathways and brain disorders. The brain contains 100 billion neurons. The BRAIN Initiative, announced by President Obama in April 2013, dedicated $300 million in public and private investments to support technologies uncovering mysteries of brain disorders such as Alzheimer's, schizophrenia, autism, epilepsy, and traumatic brain injury.

The Four Quadrant Whole Brain Model

The Whole Brain Model organizes thinking preferences into four distinct quadrants. These represent specialized thinking clusters that operate as an interconnected system. The model establishes four conscious modes of knowing:

• The A quadrant Analyzer for logic and facts;
• The B quadrant Organizer for planning and details;
• The C quadrant Personalizer for interpersonal and expressive thinking;
• The D quadrant Strategizer for imaginative and big-picture concepts.

Ned Herrmann initially used electroencephalographic equipment on test subjects at General Electric's Management Development Institute in Crotonville during the mid-1970s. Because wiring executives with equipment was impractical for gathering broad business data, he developed a metaphorical assessment tool. The Herrmann Brain Dominance Instrument quantifies relative preferences across the four quadrants. He hosted the first Whole Brain Symposium in August 1979 at GE's Management Development Institute in Crotonville, where the HBDI was born. Ongoing research now includes 2 million individual HBDI Profiles.

Thinking Preferences and Handedness

Similar to physical handedness, you develop preferred patterns of specialized thinking through increased use and life experience. Just as you develop a dominant hand through frequent use, specialized thinking patterns become preferred over nonpreferred patterns. Although you have access to all four quadrants, you tend to rely more heavily on your preferred thinking stations while other styles sit on the bench.

Try to write your full name with your nondominant hand to experience the awkwardness of operating outside your normal preference. This action demonstrates how awkward it is to engage differently from your norm, requiring deliberate practice and concentration.

• Answer the critical business questions provided in the Chapter 1 exercise regarding career aspirations, communication, corporate culture, creativity, customer relationships, cognitive diversity, job design, productivity, managing, planning, teamwork, leadership agility, and learning and growth.
• Take a pen or pencil in your nondominant hand and write your full name to experience the awkwardness of operating outside your normal preference.

2. Preferences and Competencies at Work

A preference for an activity is driven by attraction and energy, whereas competence is acquired through training and experience, though true expertise requires both.

Ned Herrmann explains that while people can build competencies in areas they do not prefer through sheer necessity or effort, true world-class expertise is almost exclusively achieved in areas of natural preference. Preferences and competencies are linked because people naturally repeat and reinforce what they enjoy.

Ned Herrmann loved physics and music as school subjects, generating boundless energy, whereas he struggled to engage in chemistry despite growing up in a family of chemists.

• Write down the subject that you liked least in school and consider if you could work on it for two years if required.
• List the key tasks required in your current job.
• Circle tasks that you enjoy the most.
• Place a checkmark next to tasks where you have an adequate level of competency to perform well.
• Underline activities that you don't enjoy or enjoy the least.

Understanding the Individual Quadrants

The Whole Brain Model divides mental preferences into four distinct quadrants representing different management styles and business functions. 5 percent of the HBDI assessment data represent people with a preference for a single quadrant, 95 percent of the HBDI database prefer two or more quadrants, and 3 percent of the database has a primary preference in all four quadrants.

Amanda is a finance manager who relies on data and return on investment (Quadrant A), Brent is a production manager who follows strict procedures (Quadrant B), Catherine focuses on customer relationships and feelings (Quadrant C), and David is a creative services manager who anticipates industry trends (Quadrant D).

Whole Brain Decision Making

The ultimate objective of Whole Brain Thinking is situational wholeness, allowing individuals to access secondary mental options and competencies when specific circumstances demand them.

Mental preferences dictate individual decision-making styles, and using a Whole Brain decision-making approach ensures that all quadrant perspectives are systematically considered. At association board meetings, Frank insisted entirely on quantitative analysis and details while Trish brought qualitative member ideas and intuition, causing friction that board president Maria had to constantly mediate.

• Identify at least one activity at work and at home that you might never normally pursue, and try it to observe motivation and energy levels.
• Analyze a recent major decision that did not have the desired outcome using the Decision-Making Walk-Around tool to identify which quadrants were paid attention to and which were overlooked.

3. Diversity in Thinking and Intelligence

Large populations form balanced composite Whole Brain distributions, and recognizing multiple intelligences improves team creativity and career alignment.

Gender and Diversity in Thinking

Data from the HBDI database consistently show males tilting toward the A quadrant and females toward the C quadrant worldwide, reflecting underlying physiological brain differences such as neuron density and cortical packing.

Ann and Ned Herrmann conducted an impromptu workshop splitting attendees of an American Creativity Association conference strictly by gender, revealing stark behavioral differences in how men and women defined the ultimate goal of creativity. Male participants focused primarily on building tangible items and specific outcomes, whereas female participants prioritized the environment, interpersonal impact, and helping people.

Homogeneous teams of either gender tend to reach consensus quickly and settle on mediocre solutions because interaction is smooth. Conversely, gender-balanced heterogeneous teams experience initial struggle and friction in decision-making, but their diverse cognitive styles enable independent yet synergistic contributions that yield superior creative outcomes. People with very similar thinking preferences can also become vigorously competitive with each other due to minor perceptual differences.

Organizational and Group Diversity

Any organization, ethnic group, or population of sufficient size naturally forms a balanced composite Whole Brain distribution. Hard data from around the world demonstrate that once a sample size is large enough, such as 1,000, 500, 250, or even as low as 100, individual profiles combine to represent a diverse yet well-balanced 1-1-1-1 distribution across all four quadrants.

Composite HBDI profiles of roughly 500 entering freshmen in a large midwestern university engineering program showed an extraordinarily well-balanced distribution across all quadrants.

To practice managing diverse cognitive styles, you can assemble a four-person team representing quadrants A, B, C, and D. You can carry out these steps:

• Identify four people in your personal or professional life who seem to have a strong preference for one of the four quadrants, so that you have one person each for A, B, C, and D.
• Determine the good news about having this group for a special project team.
• Anticipate your greatest challenge in leading this group.
• Establish how you could most effectively act as a translator across quadrants so that all ideas are heard and differences are leveraged.

Nature of Intelligence

Intellectual smartness measured by standard IQ is only one form of intelligence, and different types of smartness map across all four quadrants. People can be both smart and dull at the same time because established thinking preferences lead to competencies in discrete domains while leaving neighboring domains undeveloped.

Ned Herrmann was steered away from flight training by the Quartermaster Corps based on Army IQ scores because they believed he was suited for managing war material like uniforms and shoes.

Specific occupations have distinct mental preference norms, and only 3 percent of the total database represents quadruple-dominant profiles. A close alignment between a worker's preferences and job requirements leads to maximum job satisfaction. A corporate chairman with a D-quadrant holistic profile and a president with an A-quadrant analytical profile spent 15 years frustrating each other before discovering through HBDI assessments that their ongoing arguments stemmed from opposing mental preferences.

You can evaluate your own position by following these steps:

• Ponder whether your work provides the basis for energizing you.
• Determine what adjustments can be made in your work assignment to improve alignment if you are not energized.
• Explore other jobs that possess the alignment characteristics necessary to lead to job satisfaction and fulfillment.

4. Cognitive Diversity in Management and Communication

Unrecognized cognitive differences cause management friction and communication breakdowns that can be overcome by applying Whole Brain tools.

Managing Cognitive Diversity

Most management frustrations in modern organizations root from unrecognized differences in thinking styles rather than standard demographic diversity. While diversity is usually discussed in terms of age, race, gender, or culture, cognitive diversity is the most significant factor for organizational productivity.

Because organizations possess a balanced distribution of thinking preferences, you must move beyond a single personal style and apply multiple thinking approaches situationally.

A Whole Brain Analysis of Management Styles

In the absence of intervention, unmanaged managers default to their primary thinking quadrant, creating predictable behavioral archetypes and potential organizational blind spots. Herrmann outlines four extreme single-quadrant management styles: A-quadrant Alan is factual, technical, and analytical; B-quadrant Ben is structured, procedural, and rule-bound; C-quadrant Casey is empathetic, communicative, and people-oriented; D-quadrant Danielle is conceptual, risk-taking, and big-picture focused.

Only 5 percent of the people surveyed have thinking preferences focused on a single quadrant. Uncorrected styles harden over time and build homogenous management cultures.

Combination styles include left-mode A/B, right-mode C/D, upper A/D, and lower B/C. A multi-dominant style allows you to access all four quadrants on a level playing field, which is essential for complex roles since only 3 percent of the population has primary preferences for all four quadrants.

Studies of members of the National Inventors Hall of Fame and Lawrence Livermore National Laboratory show that an A/D-dominant profile is the preferred profile among inventors, researchers, and technologists.

A 2013 study published in Research Policy by economists Jennifer Hunt, Hannah Herman, Jean-Philippe Garant, and David J. Munroe found that 92.5 percent of all U.S. patents are held by males, down slightly from over 97 percent male fifty years ago.

You can shift your style to influence others by following these steps:

• Take a moment to identify a person who is different from you and challenging for you to work with.
• Suppose you want that person to take a specific action, one that he or she most likely will not want to take.
• Using the tips provided in Figure 7-14, determine how you would need to flex in order to convince this person to take the desired action.
• Determine what language you would use.
• Determine how you would prepare.

The Dialects of the Brain

Differences in thinking preferences create distinct mental dialects that make everyday communication highly susceptible to failure. Individuals filter the world through their mental preference profile, becoming blind or deaf in areas of lesser preference.

Ned Herrmann's architect Lou Bruinier, builder Grover Wilson, and banker Jack viewed the exact same mountain building site through completely different mental lenses, responding respectively with poetic inspiration, practical skepticism, and financial doubt about growing corn.

Statistically, more men prefer the A quadrant and least prefer the C quadrant, whereas more women tend to show the exact opposite pattern. This underlying A/C disconnect forms the root of common interpersonal friction between genders both at home and in the workplace.

To ensure critical messages are understood across a mentally diverse population, you must deliberately test and deliver messages through all four quadrants. When a company president drafts a statement to grow from $2 billion to $4 billion in annual revenues in the first five years of our long-range plan, running it through the Whole Brain Communication Walk-Around Model reveals that Quadrant A requires precise financial definitions, Quadrant B requires structural reorganization details, Quadrant C requires staff impact considerations, and Quadrant D requires a long-range vision context.

You can execute a whole-brain communication walk-around by following these steps:

• Draft the core communication statement or message.
• Test the draft statement against Quadrant A to ensure factual, quantitative, and precise terms.
• Test the statement against Quadrant B to address organizational structure, logistics, and procedural implications.
• Test the statement against Quadrant C to account for human impact, cultural tone, and employee morale.
• Test the statement against Quadrant D to incorporate big-picture context, future vision, and strategic purpose.
• Incorporate visual presentations, graphic depictions, and documentation to support the core statement.
• Offer individual meetings or open discussion sessions to address personal concerns and questions.

5. Managing, Delegating, and Learning

Performance problems often stem from a mental mismatch between an employee's thinking preferences and the job requirements rather than a lack of competence.

Mary Frankel administered the HBDI assessment to her 12 benefits specialists and discovered that the 8 high performers were homogeneous with a strong B-quadrant tilt, while the 4 struggling specialists had C or D preferences that conflicted with procedural job requirements. Mental mismatches increase stress, anxiety, and health issues. When Sean, an account executive who struggled with B-quadrant details and budgets, was moved into a Creative role where his D-quadrant preferences matched the work, he won a national advertising award for his very first campaign.

Managing and Delegating

Managers do not create employee motivation; instead, motivation comes from within each individual. Your responsibility is to provide stimulating work and remove barriers. Effective delegation requires a shared understanding of tasks and goals, which can be systematically verified using specific diagnostic tools to prevent miscommunication caused by mental differences.

You can manage up and boost your own engagement by setting higher personal performance standards than those expected by your boss. You might set an objective to earn your salary by June, April, or March, treating everything after that date as added value.

Productivity and Fit

Proper job matching produces a 30 percent potential productivity gain in the average business group. Gallup data shows that only 30 percent of employees are actively engaged. When mental mismatches cannot be avoided, you must help employees address blind spots through support and tools.

When addressing misalignment, follow these practical steps:

• Analyze the work elements of tasks, projects, and jobs according to the quadrant they call for.
• Set priorities to identify the most important, primary elements required and the percentage time allocation for each.
• Refrain from casually or inadvertently adding responsibilities to that position for administrative convenience.
• Educate employees at all levels about how their thinking preferences relate to their productivity, effectiveness, and satisfaction.
• Cooperate with employees' efforts to adjust job tasks consistent with getting the job done.
• Provide productivity tools that align with the person's thinking preferences, or give the person freedom to select the tools that work best.
• Address any blind spots that come from areas of low preference by providing training, support, and other tools.
• Measure the resulting productivity gains.

Aligning learning methods, mentoring pairs, and daily routines with thinking preferences accelerates capability and retention.

At GE's Crotonville complex, Ned Herrmann studied a participant group of 20 people and found that less than half of the learning achieved was what was actually intended by the training program. Grades in the School of Dentistry at the University of Pretoria improved by 30 percent after the tooth morphology class was transformed using a Whole Brain Learning redesign. At the U.S. Naval Command, matching mentors and mentees based on their thinking preferences led to a 99 percent success rate of relationships lasting over time, compared to a previous success rate of 50 percent.

Learning and Development

Building situational capability across all four thinking quadrants requires regular, daily practice of quadrant-specific activities, much like building a physical muscle. Adult learning requires energy, focus, and overcoming the discomfort of processing new information.

You can use these practical steps to develop all four quadrants:

• Review your financial status for the current week, the past month, and the year to date.
• Plan this week's priority activities, and schedule them on your calendar with reminders.
• Show someone who needs empathy that you care by taking the initiative and verbally expressing it in a way that the person will appreciate.
• Draw a metaphor of your last vacation or activities you engaged in last week, and have someone else look at it and interpret the meaning.

6. High-Performance Teams and Leadership

Heterogeneous teams and customer-focused communication strategies outperform homogeneous groups by leveraging constructive cognitive diversity.

Teams That Work

Homogeneous teams achieve consensus quickly but suffer from groupthink, whereas heterogeneous teams struggle with initial agreement yet produce superior, more creative solutions. Teams composed of people with similar thinking preferences can quickly align and respond consistently, making them ideal when speed is the primary goal. Conversely, diverse teams face technical and communication barriers that delay consensus, but their combined perspectives lead to comprehensive and innovative outcomes.

In a U.S. Forest Service study, whole-brained teams were 66 percent more efficient than homogeneous teams when faced with complex challenges. Furthermore, 70 percent of whole-brained teams successfully completed their assigned project, compared to 30 percent or less for non-whole-brained teams.

Shell Oil brought together a team of world-class experts to design an offshore drilling rig, but impenetrable silos formed because they could not relate to solutions outside their specific expertise. Only after understanding their differing perspectives using the HBDI Team Profile did they achieve a breakthrough. Diverse teams require skilled leadership and an upfront investment of time to build a climate that embraces cognitive differences rather than devolving into conflict.

Influencing and Connecting with Customers

To influence others effectively, people must abandon the Golden Rule and instead apply the Platinum Rule by tailoring their message to the recipient's thinking preferences. Every business role involves selling ideas, products, or influence. Because receivers have low tolerance for mismatched communication styles, identifying how a customer or stakeholder thinks allows the sender to speak their language and accelerate agreement.

Susan spent seven years failing to interest Dr. Wilburn in pharmaceutical products using clinical data until she noticed his passion for advanced boating technology, realizing he was a conceptual, people-oriented thinker rather than purely clinical. Aligning product design, marketing, and customer service approaches with Whole Brain thinking preferences dramatically increases customer satisfaction and financial return. Telecom New Zealand implemented Whole Brain Thinking training for call center representatives to help them adapt their communication style to customers' thinking preferences, resulting in increased satisfaction scores and a 12-to-1 return on investment in the first year. For every $1 Telecom New Zealand invested in the Whole Brain Thinking program during the first year, it made $12 in return.

When preparing any important discussion or presentation, a speaker should systematically cover all four quadrants to ensure the audience's needs are fully met. You can use these Whole Brain steps to guide your approach:

• First, give context to clarify very early on why you are there: What it is that you want to get across and why? What's the big picture? Why does this matter?
• Have an agenda or outline in mind, even if it's brief, to let the person or people know where you're going and what to expect—and then stick to it.
• Present the key data and facts that back up your intention.
• Engage with interactions and relevant stories, make great eye contact, and listen.

Whole Brain Leadership

As leaders advance through the stages of the Leadership Pipeline, the required thinking shifts from tactical execution toward interpersonal collaboration and strategic big-picture vision. The Leadership Pipeline model maps directly against the Whole Brain Model, showing that B-quadrant tactical thinking dominates lower levels, C-quadrant interpersonal thinking grows in middle stages, D-quadrant strategic thinking emerges strongly at higher levels, and A-quadrant analytical thinking remains consistent. This model was based on 30 years of consulting work with Fortune 500 companies.

Leaders at CLP India learned that their technical and analytical style was insufficient for renewable energy expansion, prompting them to build up C-quadrant collaboration and D-quadrant innovation. Effective leadership in a complex world requires breaking habitual thinking patterns and developing situational agility across all four quadrants of the Whole Brain Model. A multinational firm leader accustomed to living in the A-quadrant for numbers and performance realized through coaching that he had neglected C-quadrant relationship skills, prompting him to develop his less-preferred modes.

7. Organizational Alignment and Strategic Thinking

Most organizations suffer from severe misalignment between their documented vision, mission, and values and the actual behavior of their management. Documents like mission statements and corporate values are often created separately by committees at different times, reflecting inconsistent thinking preferences. When leadership behavior does not match these stated words, employee trust, credibility, and engagement erode rapidly.

Sustainable business success requires aligning enterprise values, annual reports, and strategic thinking processes with Whole Brain principles.

Ned Herrmann used the HBDI Text Profile to analyze a billion-dollar communications company's mission and values statements, only to discover from employees in a Japanese restaurant that they had trashed their company cards because management's crass behavior completely contradicted the stated values. Individual alignment between personal thinking preferences and daily work activities is a primary driver of competitive advantage and self-actualization. Most people are out of alignment with their school, career, or job, forcing them to struggle unnecessarily. When an organization matches work packages to employee mental preferences, effort becomes free-flowing, productivity increases, and engagement rises.

Growing Companies

Companies surviving infancy often develop a rigid short-term operational focus that kills long-term innovation and leads to failure in late adolescence. For survival, early-stage businesses must shift focus to immediate cash flow and operational execution, leaning heavily on A and B quadrants. If they fail to swing back to a multidominant, whole-brained center that values C-quadrant talent and D-quadrant innovation, they run out of steam and die in late adolescence.

Actuarial statistics show that for every 100 new businesses, fewer than 50 survive the first 5 years, and fewer than 33 survive the first decade. To transform the business without losing core values, Cookie Time used the HBDI to identify thinking preferences and the Whole Brain Model to communicate vision and guiding principles, securing employee buy-in and improving financial performance. Cookie Time, an iconic New Zealand snack company with 42 franchises, used Whole Brain Thinking to transform the business and become the most-loved snack foods brand while maintaining core traits. At a meeting for DuPont's top 200 high potentials, Ned Herrmann revealed that their annual report titled 'A Global Entrepreneur' was heavily tilted to the A-quadrant financial mentality rather than D-quadrant vision. The company later adjusted its reports and won the prestigious Mead Award for Best Annual Report.

The Essential Shift to Strategic Thinking

Effective strategic planning requires strategic thinking, which is primarily a D-quadrant process and must precede operational planning. While operational planning relies on B-quadrant structure, facts, and logic, strategic thinking deals with future trends, vision, synthesis, and fuzzy logic. Traditional training focuses too much on analytical techniques while overlooking the creative D-quadrant mentalities needed for true strategy.

Transitioning traditional managers into strategic thinkers requires specific non-traditional processes like knowing preferences, using metaphors, and building models. To help analytical leaders break out of their comfort zones, organizations must implement structured mental transition steps that unlock intuition, visualization, and D-quadrant capabilities.

• Know your preferences
• Define strategic thinking
• Stretch to and leverage D-quadrant thinking
• Get uncomfortable
• Use metaphors
• Build models to tap into your innate creativity and gain strategic insight
• Understand the mentality of your culture
• Step out into the future

Vehicle and animal metaphors bypass rational censorship to reveal unarticulated points of view about a company, competitors, or future states. Drawing imaginary vehicles or using animal attributes allows individuals and teams to express unarticulated perspectives, environmental obstacles, and future strategic visions that words alone cannot capture. A semiconductor company used animal metaphors to describe stakeholders and suddenly realized that distributors treated as substandard backups were actually their best untapped option for increasing market share.

• On a blank sheet of paper, draw a car or some other vehicle that represents your company as you see it today
• Sketch in the environment, noting whether the road is bumpy, has a dead end, or a long road ahead
• Draw another vehicle that represents how your company should be in the future, say in 8 to 10 years, if successful
• Compare the two to determine what is different and what needs to change to reach that future point

8. Reorganization, Disruption, and Change

Transformations and crisis responses fail when leaders rely solely on left-mode metrics instead of embracing human and cultural elements.

Reorganization and Reinvention

Interventions like reengineering are painful and costly when conceptualized solely through left-mode preferences. Reversing the default planning flow to start with C and D quadrants helps address people, communication, vision, and culture more effectively.

Ann McGee-Cooper and Duane Trammel worked with an engineering company whose HBDI Team Profile flow went from B to A to D to C, leaving no time or energy for creativity or human concerns. By redesigning meetings to flow from C to D to A to B, they achieved a successful reorganization.

A national bank acquiring a regional bank closed 40 co-located branches with no forced transfers or retrenchments, reduced staff turnover from 14 percent to 6 percent, saved a $10 million redundancy fund, and gained 86 percent support for the industrial relations agreement. This massive success relied on establishing a Merger Management Team with C and D preferences to focus on culture and community, rather than relying solely on executive A/B thinking.

Dealing with Disruption

During a second economic downturn, the CEO of a growing business used strict A-quadrant linear cuts across the board, canceled product launches, and trimmed marketing, which resulted in much heavier losses and years of lost momentum compared to the first downturn. Knee-jerk budget cuts, micro-management, and eliminating discretionary spending feel productive, but they destroy creativity, alienate employees, and cause greater losses during crises than balanced approaches.

Making Change Work

Mindsets act as cognitive filters and mental maps anchored in brain synapses. According to Dr. Edward Miller from Johns Hopkins University, 90 percent of patients who undergo triple bypass surgery fail to change their lifestyles despite facing a life-threatening situation.

A global consumer packaged goods company trained over 60 change agents in Whole Brain Thinking before an acquisition, allowing them to map cultural differences and facilitate open dialogues about fears and concerns across international locations. Change triggers different fears across quadrants: A fears ambiguity, B fears unpredictability, C overreacts emotionally, and D fears confinement.

• Install a Whole Brain management team in leadership roles
• Create Whole Brain implementation teams
• Apply appropriate creative processes in all activities of leadership and implementation teams
