GUILHERME ATSUMI
I help organizations structure decision-making, governance, and execution systems in complex environments,
reducing improvisation, sustaining choices, and turning strategy into consistent practice.
My purpose is to bring clarity to you and your organization’s work, reducing cognitive load and enabling
collaboration so workflows can truly flow.
I operate across three complementary levels that sustain decisions over time and reduce improvisation.
Structuring operating models, decision criteria and governance mechanisms that align strategy,
priorities and execution.
The focus is to reduce ambiguity, clarify roles and build sustainable routines, with clear criteria and indicators
to support decisions and monitoring.
Design and production of content, learning journeys and capability structures connected to strategy and real work
execution.
Includes group facilitation, workshops, meetups and events, and experience design that strengthens organizational
capability, engagement and adoption.
Support to build systems that hold over time, considering social, environmental and organizational impact.
Includes indicators, monitoring dashboards and feedback cycles that guide decisions, continuous learning and the
responsible evolution of the system.
Structuring and consolidating organizational systems in real contexts.
Below are examples of interventions where I designed, structured and consolidated organizational capabilities in
environments with scale, ambiguity and multiple stakeholders — from zero to sustained operation.
Growing organizations managing dozens of simultaneous initiatives, with low portfolio visibility and decisions excessively dependent on individual leaders.
Design and implementation of PMO structures, prioritization criteria, governance rituals and portfolio tracking models, connecting strategy, resource allocation and execution.
Greater clarity on strategic priorities, fewer conflicts between initiatives, and increased predictability and coherence of decisions at executive level.
Organizations seeking to innovate or transform without a clear decision structure, governance and integration with day-to-day operations.
Structuring innovation and transformation areas, defining mandate, operating model, governance and integration with business and technology teams.
Innovation initiatives more aligned to strategy, reduced disconnected effort, and increased ability to turn experiments into organizational results.
Corporate and educational environments with hundreds to thousands of people, high content production and low practical impact on execution.
Design of learning portfolios, strategic journeys and capability structures connected to real work execution, with adoption and impact metrics.
Stronger coherence between learning and strategy, increased practical application, and sustained strengthening of organizational capability over time.
Teams and leaders operating with fragmented data, decisions based on perception and low visibility into performance and bottlenecks.
Design of measurement and decision systems, including strategic KPI definition, executive dashboards and automations to support decision-making.
Better-informed executive decisions, reduced operational noise, and greater ability to anticipate risks and prioritize investments.
Growing or transforming organizations under market pressure, with multiple external stakeholders and misalignment between strategy, promise and delivery capability.
Structuring positioning and prioritization criteria for GTM decisions, aligning product, operations and communication, and improving interfaces with customers, partners and investors.
Greater coherence between strategy and execution, reduced friction across external interfaces, and increased ability to sustain growth without compromising operations.
Social, educational and sustainability projects involving multiple partners, volunteers and funders, requiring legitimacy and continuity.
Design of governance, evaluation and impact monitoring models, integrating purpose, operations and institutional accountability.
Greater clarity on results generated, strengthened governance, and increased sustainability of initiatives in the medium and long term.
Practice labs for reflection and method development
Beyond organizational work, I develop authorial projects where I experiment, structure and share concepts, practices and models related to decision-making, leadership, learning and human development. These initiatives work as synthesis environments between thinking, practice and education.
A practical system for managers who need to decide when to use process, project or product, avoiding management fads and context-misaligned choices. It structures decision criteria, ways of working and sustainable execution.
A podcast with stories and conversations about self-awareness, inclusion and transformation, exploring personal and professional journeys, contemporary dilemmas and processes of individual and collective change.
A space for listening, reflection and expanded awareness, connecting real experiences to themes such as leadership, identity, work and purpose.
A journey and content focused on human development, meaning and lifelong learning. It brings together courses and materials about self-awareness, choices, life cycles and building meaning.
Collaboration, collective intelligence and facilitation methodologies applied to organizations, groups and communities. It explores dialogue, listening, co-creation and collective decision-making practices.
In development
A leadership journey grounded in Resilience, Empathy, Authenticity and Legacy, for people who hold or are preparing for leadership roles in complex contexts.
It treats leadership as a process of awareness and responsibility, going beyond technical skills to address posture, impact and coherence between speech and practice.
Community management and identity building, connecting purpose, narrative and presence in the world.
Consulting and facilitation for leaders and organizations, connecting people, decisions and collective action.
Structuring data systems and executive dashboards for strategic decision-making, integrating operations, finance and long-term vision.
Decision-oriented work focused on structure and long-term sustainability. I work with people and organizations when the challenge is not lack of capability, but excess complexity, ambiguity or decisions that don’t hold in practice.
To structure organizational systems that sustain.
For decisions in moments of complexity, transition or growth.
For entrepreneurs and initiatives — especially social-impact ones — who need to structure work, routines, positioning and priorities, connecting purpose, operations and viability.
For executives and leaders in complex contexts. Focus on improving decisions, structuring criteria, dealing with trade-offs and sustaining choices over time.
For professional repositioning. Organizing experience, reading context and building coherence between your story and next steps.
TEACHING
I work as a professor, tutor and content designer across undergraduate, graduate and executive education programs, with a focus on strategy, management, sustainability, innovation, leadership and organizational learning. My approach integrates solid theoretical grounding with practical experience in real organizational contexts, avoiding purely conceptual or work-disconnected teaching. Over this trajectory, I have developed and delivered courses, workshops and learning journeys focused on decision-making, work organization, project and process management, ESG and human development — always prioritizing practical application and critical thinking.
ACADEMIC ACTIVITYIf you’re dealing with decisions that don’t hold, growing complexity, or the need to structure execution more effectively, we can talk to assess whether moving forward makes sense — and how.
