Why Simplicity and Speed Matter More Than Complexity in Organizational Transformation

When Claudia Toussaint arrived at UCLA's admissions office after being rejected, she wasn't there to argue or plead. She wanted to understand what she could do better. That conversation led to her admission and taught her a lesson about resilience and learning mindsets that would shape her approach to organizational transformation decades later.

Now, as Chief People and Sustainability Officer at Xylem, a global water solutions provider with 23,000 employees across 150 countries, Toussaint has applied those same principles to guide the company through a major operating model transformation following its 2023 acquisition of Evoqua Water Technologies. In a recent interview with McKinsey, she outlined an approach that challenges conventional transformation wisdom by prioritizing culture over structure and simplicity over complexity.

The Culture-First Imperative

Most organizations facing major transformations instinctively reach for the organizational chart. The logic seems sound: define new structures, assign roles, then let culture follow. Toussaint argues this sequence is precisely backward, especially during mergers and acquisitions.

"Many companies start with structure first, but we started with culture because we had the acquisition," Toussaint explains. "Sometimes when going through mergers and acquisitions, if you don't pay attention to culture, you risk not realizing the full potential of the combination."

This insight aligns with extensive research on M&A failures. Studies consistently show that 50-70% of mergers fail to achieve their stated objectives, with cultural integration challenges cited as a primary factor. Edgar Schein's seminal work on organizational culture emphasizes that culture operates at deep levels of basic assumptions that resist change unless explicitly addressed. When organizations prioritize structural changes while ignoring cultural integration, they essentially build new architectures on unstable foundations.

Yet Toussaint's approach extends beyond risk mitigation. By treating culture as "a derisking mechanism," Xylem transformed what many view as a soft, peripheral concern into a strategic asset. This reframing matters because it positions HR and culture work as central to value creation rather than as support functions managing the human consequences of strategic decisions made elsewhere.

The practical application at Xylem involved comprehensive executive workshops where C-suite leaders practiced desired behaviors and held each other accountable. Toussaint introduced the concept of "calling people in" rather than calling them out—a subtle linguistic shift that creates psychological safety while maintaining high standards. "You can't just put it on a piece of paper; you have to put in the time and do the work as a leadership team," she notes.

Research from Boston Consulting Group supports this behavioral focus, showing that transformations with strong people-centered approaches are 2.5 times more likely to succeed. However, BCG also emphasizes the importance of clear metrics alongside cultural work, suggesting that the most effective approaches balance the qualitative aspects of culture change with quantitative accountability structures.

The Power of Radical Transparency

One of Xylem's most distinctive choices involved sharing transformation plans with 150 senior leaders far earlier than typical change management protocols recommend. When most organizations guard structural decisions closely to avoid anxiety and speculation, Xylem did the opposite.

"A lot of times, when you go through an operating model change, by the time you think about structure, you're being fairly secretive about it," Toussaint observes. "But we were transparent with that team, which built trust. Those 150 leaders became advisers to the C-suite."

This radical transparency carries risks. Premature disclosure can trigger unintended consequences including talent flight, competitive intelligence leaks, and premature resistance. The conventional wisdom of limiting information flow until decisions solidify has practical foundations.

Yet Toussaint's experience suggests these risks may be overstated relative to the trust and engagement benefits of transparency. By treating 150 leaders as advisers rather than implementation targets, Xylem tapped into distributed organizational intelligence. These leaders understood operational realities, customer relationships, and cultural nuances that executive teams often miss. Their input improved decision quality while their early engagement created a broad coalition of change champions.

This approach reflects principles from the field of participatory design and open-book management. Research by Jeffrey Pfeffer and others has demonstrated that transparency about organizational challenges and strategic decisions increases employee commitment and problem-solving contributions. When people understand the full context, they make better local decisions that align with organizational objectives.

The investment in this group extended beyond transparency to development. Xylem put all 150 leaders through a six-week learning program focused on aligned leadership and change management methodology. This dual emphasis on inclusion and capability building transformed potential resistance into advocacy.

Simplicity as Competitive Advantage

In an environment where consultants often deliver 200-slide decks and transformations spawn dozens of workstreams, Toussaint's emphasis on simplicity stands out. Xylem deliberately simplified its vision and mission statements, reduced the number of target behaviors, and streamlined decision-making processes.

"Making things simple was the key theme throughout the operating model transformation," Toussaint emphasizes. "We kept the language simple, and we kept the number of behaviors simple because we wanted people to remember them."

This commitment to simplicity extended to Xylem's purpose statement: enabling and empowering customers and communities to build a water-secure world. The clarity and brevity make it memorable and actionable in ways that elaborate mission statements rarely achieve.

Research on change communication consistently demonstrates that simple, repetitive messaging improves adoption. Cognitive psychology research shows that human working memory can effectively process only a limited number of elements simultaneously—typically between four and seven. When organizations introduce complex change frameworks with multiple dimensions, numerous priorities, and sophisticated terminology, they exceed cognitive capacity. People resort to simplification anyway, but without guidance, they simplify inconsistently.

Yxlem's approach also addressed what could be called "collaboration obesity." Many organizations suffer from too many decision-makers, excessive meeting attendance, and unclear role definitions. Toussaint describes moving "from overcollaborating to collaborating well" by establishing smaller steering committees with clear purposes and helping people understand whether they're decision-makers or simply need to be informed.

This resonates with research on decision rights and organizational effectiveness. Studies by Gary Neilson and others have found that organizations with clear decision rights outperform peers by significant margins. The issue isn't too much collaboration per se, but rather ambiguous accountability that slows decisions and diffuses responsibility.

However, simplification carries risks. Overly reductive approaches can miss important nuances, fail to address legitimate complexity, and alienate sophisticated stakeholders who perceive the simplicity as simplistic. The challenge lies in achieving what Oliver Wendell Holmes called "simplicity on the other side of complexity"—distilling essential truths without losing critical distinctions.

Speed Through Discomfort

Toussaint draws an unexpected analogy between transformation and yoga practice: "The great yoga teachers say that the pose starts when you really want to get out of the pose. That means true growth takes place when we push beyond our comfort zones."

This philosophy translated into an emphasis on speed that often felt uncomfortable. "There were moments during the operating transformation when I felt, 'OK, we're at a point where I'm not sure we can do it.' But I'm really glad we moved with speed and moved through the pain."

The emphasis on velocity aligns with research showing that prolonged transformations lose momentum, create change fatigue, and allow resistance to organize. The longer a transformation takes, the more opportunity exists for competing priorities to emerge, leadership attention to drift, and skepticism to build.

Yet speed as a transformation principle deserves critical examination. Research by Heike Bruch and Jochen Menges on "the acceleration trap" warns that organizations can overload themselves by pursuing too many activities too quickly. Their studies found that 92% of companies fall into periods of overloading, leading to employee burnout, declining performance, and ultimately slower progress.

The key distinction appears to be between speed that creates focus and speed that creates chaos. Xylem's approach emphasized rapid decision-making and implementation within a simplified framework with clear priorities. This differs from speed manifested as multiple simultaneous initiatives, constantly shifting priorities, or insufficient time for consolidation.

Toussaint also emphasizes that speed requires CEO conviction and board alignment. "A transformation of this magnitude must be driven by the CEO's deep conviction and an aligned board," she notes. Without this top-level commitment, the organization will sense hesitation and momentum will stall.

This observation highlights a potential limitation of the approach. Organizations lacking CEO conviction or board alignment cannot simply will these elements into existence. The transformation strategy assumes a level of leadership unity that may not exist in many organizations facing the greatest need for change.

Preservation Amid Transformation

While much transformation literature focuses on what must change, Toussaint emphasizes the equal importance of what should remain constant. "I knew what needed to change and what needed to be preserved," she explains, citing Xylem's purpose-driven culture and sustainability leadership as competitive advantages worth protecting.

This balanced perspective reflects sophisticated change management thinking. Organizations possess assets, capabilities, and cultural attributes that drove past success and remain relevant for future competitiveness. Indiscriminate change risks destroying sources of advantage along with genuine problems.

Jim Collins and Jerry Porras explored this concept in their research on enduring companies, distinguishing between core values that remain fixed and operating practices that adapt to changing environments. Their framework suggests that successful organizations preserve core ideology while stimulating progress and change in everything else.

For Xylem, purpose and sustainability represented core elements worth preserving. The company's mission around water security attracts talent, drives engagement, and differentiates its market position. As Toussaint notes, "Purpose attracts talent and drives people to be engaged and to give 150 percent."

This approach also addresses a common transformation pitfall: throwing out organizational capabilities and knowledge in pursuit of something entirely new. Research on organizational memory and knowledge management demonstrates that tacit knowledge embedded in relationships, routines, and culture is difficult to recreate once lost. Organizations that destroy too much in transformation often find themselves trying to rebuild capabilities they once possessed.

The Untapped Talent Thesis

One of Toussaint's most surprising discoveries during the transformation was "how resilient an organization can be—and how much untapped talent can be found to help champion change."

This observation challenges implicit assumptions in many transformation approaches. The conventional view often treats employees as change-resistant forces requiring careful management and persuasion. While this perspective has some validity—humans naturally resist uncertainty and loss—it can become a self-fulfilling prophecy.

When leaders assume resistance, they design change processes that limit participation, withhold information, and focus on overcoming objections. These approaches can actually create the resistance leaders feared, as employees respond to being excluded and controlled.

Alternatively, when leaders assume capability and potential contribution, they design inclusive processes that tap into distributed knowledge and energy. Toussaint's experience suggests this positive assumption often proves correct. Organizations contain people at all levels with insight, capability, and willingness to contribute to meaningful change.

Research on employee engagement and discretionary effort supports this view. Gallup's extensive studies show that engaged employees perform significantly better, but that most employees are not engaged. The gap between current and potential contribution is substantial. Effective change processes can close this gap by providing meaningful ways for people to contribute.

However, this perspective risks underestimating legitimate sources of resistance. People may resist change for good reasons: poor past experiences with transformation, well-founded concerns about proposed directions, or recognition of implementation challenges leaders have missed. Dismissing these concerns as resistance to change rather than substantive feedback represents a significant mistake.

The balance lies in approaching organizations with realistic optimism: expecting to find significant untapped talent and constructive contributions while remaining alert to legitimate concerns and genuine implementation challenges.

The Evolving Role of Chief People Officers

Toussaint's perspective on the CPO role reflects its evolution from administrative function to strategic partner. She emphasizes understanding how external volatility affects the business and addressing talent implications, particularly around artificial intelligence.

"Every organization on the planet is thinking through how to leverage AI, both in terms of customer-centric use cases and in terms of augmenting leaders' capabilities," she observes. "Chief people officers have an opportunity to be very purposeful in discussing what roles and tasks may change and where there are opportunities."

This strategic positioning of the people function represents a significant shift from traditional HR roles focused on policy administration, compliance, and transactional services. Research by Dave Ulrich and others has tracked this evolution, identifying multiple roles for HR: strategic partner, change agent, administrative expert, and employee champion.

Toussaint's background as a corporate lawyer for 30 years before moving into HR leadership illustrates an increasingly common pattern: people leaders with diverse professional experiences bringing broader business perspectives to the role. This diversity of background enables CPOs to engage more effectively with business strategy, risk management, and operational challenges.

Yet this evolution also creates tensions. As people leaders focus more on strategy and transformation, who handles the essential operational work of talent acquisition, development, compensation, and employee relations? The risk is that in pursuing strategic relevance, people functions neglect foundational capabilities that remain critically important.

The most effective people leaders appear to maintain excellence in core HR capabilities while expanding into strategic territory. This both-and approach requires building strong teams, leveraging technology for administrative efficiency, and developing personal capabilities across traditional and emerging domains.

Critical Questions and Limitations

While Xylem's approach offers valuable insights, several questions deserve consideration:

First, how much does the "position of strength" context matter? Toussaint explicitly notes that Xylem embarked on transformation while performing in the top quartile for shareholder returns over a decade. Organizations in crisis face different challenges: skeptical stakeholders, limited resources, urgent timelines, and potentially damaged cultures. Can culture-first, transparency-focused approaches work when immediate financial results matter most?

Research on turnarounds suggests that crisis situations often require rapid, decisive action focused on immediate financial stabilization before broader transformation work can succeed. Lou Gerstner's IBM turnaround famously began with stopping financial hemorrhaging rather than culture change, though culture work became essential later.

Second, how scalable is the approach? Xylem invested significantly in developing 150 leaders through six-week programs and extensive C-suite workshops. Organizations with tighter resource constraints may struggle to replicate this investment. What represents the minimum viable version of this approach?

Third, how do you measure cultural change effectiveness? Toussaint describes positive feedback from employees and channel partners, and notes improvements in decision-making speed. But culture change often proves difficult to quantify. Without clear metrics, how can organizations assess whether cultural investments deliver adequate returns?

Fourth, what happens after initial transformation? Xylem's transformation appears to be succeeding in its early stages, but sustaining change over time presents different challenges than initiating it. How does the organization avoid regression to old patterns as attention shifts to new priorities?

Practical Implications for Business Leaders

Despite these questions, Toussaint's experience offers several actionable insights for executives facing transformation:

• Start with culture, especially during M&A. Rather than treating culture as a consequence of structural changes, position it as a foundation. This requires investment in understanding both cultures, defining desired future culture, and working systematically on integration.
• Simplify ruthlessly. Resist the temptation to create comprehensive frameworks covering every contingency. Identify the few critical priorities, behaviors, and messages that matter most. Test whether people can remember and act on what you're communicating.
• Invest in leadership alignment and capability. Executive team workshops and broader leadership development aren't luxuries—they're essential infrastructure for change. Leaders must model desired behaviors consistently, which requires practice, feedback, and accountability.
• Move faster than feels comfortable. Extended transformation timelines create opportunities for momentum loss. Set aggressive timelines while maintaining focus on the simplified priorities that matter most.
• Balance change with preservation. Identify core strengths, capabilities, and cultural attributes worth protecting. Communicate these clearly so people understand what remains constant amid change.
• Assume untapped talent and capability. Design inclusive processes that tap into organizational knowledge rather than processes that simply overcome resistance. Provide meaningful ways for people to contribute.
• Ensure CEO and board conviction. Without top-level commitment, transformation efforts will fail. If conviction doesn't exist, building it becomes the first priority before launching broader change.

Claudia Toussaint's journey from showing up at UCLA's admissions office to leading a major organizational transformation embodies a consistent philosophy: combine resilience with learning mindsets, embrace discomfort in service of growth, and focus on what truly matters rather than performative complexity.

Her approach challenges several orthodoxies in organizational transformation: that structure should precede culture, that transparency creates unmanageable risk, that comprehensive frameworks demonstrate rigor, and that slow, careful change minimizes disruption. The Xylem experience suggests alternative paths exist.

Yet the approach isn't universally applicable. Context matters enormously—organizational crisis, resource constraints, leadership capability, and cultural starting points all affect what strategies can work. The insights from Xylem's transformation provide principles to adapt rather than templates to copy.

The deeper lesson may be about conviction and coherence. Toussaint and Xylem's leadership committed fully to a clear philosophy: culture first, simplicity throughout, speed despite discomfort, and preservation of core strengths alongside necessary change. This coherent approach, consistently applied, appears to matter more than the specific choices within it.

As organizations face ongoing disruption from technology, climate change, geopolitical instability, and evolving workforce expectations, transformation becomes not an occasional project but an ongoing capability. The leaders who develop this capability by focusing on culture, simplifying relentlessly, moving with conviction, and tapping into human potential position their organizations to navigate whatever changes emerge.

Toussaint's advice to executives embarking on transformation ultimately returns to fundamentals: have conviction, ensure CEO buy-in, stay curious, keep learning, and invest in relationships across the organization. These may sound simple, even obvious. But in their application lies the difference between transformation that endures and change initiatives that fade.
