We want you to get real value from this training — and to know exactly what you're getting. Please take a moment to read these notes.

Readings & external references

• Not everything is free to access. Each module references the materials most relevant to its topic so you can go deeper. We list them for completeness and rigor, but not all are freely available — some require purchase, a subscription, or library or institutional access — and we are unable to provide those materials directly.
• Links can break over time. We make every effort to provide working links to external materials. Because external websites change, some links may eventually stop working. If you find a broken link, please let us know (see Contact) and we will replace it with a current, relevant source. In the meantime, we recommend locating the material by running an alternative search — including with a different search engine — using the title, author, or key terms provided.
• A link is not an endorsement. External links and referenced works are provided for educational purposes. We do not control, and are not responsible for, the content, accuracy, availability, or privacy and terms of third-party websites, and linking to them does not imply our endorsement.

The nature of this content

• For education, not advice. This training is provided for professional-development and educational purposes only. It does not constitute professional, legal, financial, medical, or psychological advice, and is not a substitute for guidance tailored to your specific situation.
• No guaranteed outcomes. The concepts, frameworks, and practices are intended to inform and support your work. Results depend on context, implementation, and factors beyond the training, and we make no guarantee of specific business, team, or individual outcomes.
• A point in time. The content reflects the research, sources, and practices available at the time it was produced. These fields evolve, and we update our materials periodically; this training is not a substitute for consulting current primary sources.

Intellectual property & permitted use

All course content is © The Flow Consortium LLC and Professional Development Network LLC, provided under a personal, non-transferable license for your individual learning. It may not be copied, redistributed, resold, or used to train others or to deliver services, without our written permission.
• Third-party frameworks and trademarks. The Flow System integrates and references third-party frameworks, methods, tools, and works — for example, Cynefin, the Toyota Production System, and human-centered design, among others. These remain the property of their respective owners, are referenced for educational and commentary purposes, and their inclusion does not imply affiliation with, or endorsement by, those owners.

Practical notes

• Knowledge checks. The knowledge checks within each module are learning tools for self-assessment and reinforcement. Completing them does not confer an accredited certification or professional credential.
• Worksheets and downloads. Worksheets, templates, and downloadable resources are provided as-is to support your practice; please adapt them to your context. We make no warranty of fitness for a particular purpose.
• Languages. Spanish captions are provided for accessibility and convenience. If there is any discrepancy between languages, the English-language content is the authoritative version.
• Access. Access to purchased content is time-limited according to the product you bought; the access window is shown at checkout and on each product page. Please complete your learning within that window.
• Updates and corrections. We reserve the right to update, revise, correct, or remove content and links at any time.
