Effectual Action Manifesto

https://effectuation.org/stories/x-portfoliomanifesto-for-effectual-action-manifesto-para-a-acao-efetual

Everything starts with YOU with your own means
your identity, your knowledge and competencies, and your network

You don't have to be a risk taker, each step you give is always within
YOUR AFFORDABLE LOSS

The paths you start exploring are bound only by
YOUR IMAGINATION

The paths you get to build are those that are
CO-CREATED
with people who commit themselvs to enrich and transform
the path in-the-making with their own means and goals

YOU WELCOME SURPRISE
as an input for the transformation of the path
You don't predict the future
You leave that for the musings of fortune tellers and economists
You make it happen
using the means, choosing the paths and calibrating each step so that
YOU ARE IN CONTROL
You can learn to build the path and you can get better at it

ANYONE CAN!
You just have to start
DO IT NOW!

This is the Manifesto for Effectual Action

Entrepreneurship is a human centered method aimed at positive transformation of present conditions, especially equipped to deal with extreme uncertainty and ambiguity. Entrepreneurs are the ones that act within their own capacity and sphere of control in order to co-create with others new and positive forms of value. Startups are the institutions that take shape with the actions of entrepreneurs and their partners along their co-creation path. Action can take place in launching a new technological startup or in the making of a new public service within a governmental organization. It can be within the for-profit or non-profit domains.

Sept'2026: How does this model differ most from the Lean Startup model (per Eric Ries and Ash Maurya)?

The most fundamental difference is that Effectuation focuses on who you are, while the Lean Startup focuses on what you want to achieve.

While both models are designed to handle extreme uncertainty, they approach the problem from completely opposite directions: Lean Startup is a scientific method of hypothesis testing, while Effectuation is a human-centric philosophy of co-creation.

Here is how Effectuation differs most from the Lean Startup model (per Eric Ries and Ash Maurya):

1. The Starting Point (How to Begin)

• Lean Startup: Starts with a specific vision or problem statement. You form a hypothesis about a market need and build a Minimum Viable Product (MVP) to test it.
• Effectuation: Starts with the "Bird-in-Hand" principle. You look at your current identity (Who am I?), your skills (What do I know?), and your network (Whom do I know?). You take action based on available means, not a pre-conceived goal.

2. View of the Market and the Future

• Lean Startup: Views the market as knowable through discovery. The future is unpredictable, but you can navigate it by treating the market as a lab. You build, measure, and learn to find existing demand.
• Effectuation: Views the market as inherently non-existent. You do not discover markets; you create them. Because the future is man-made, you do not waste time predicting or even testing it—you control it through action.

3. Risk and Financial Management

• Lean Startup: Focuses on minimizing waste. You burn cash carefully to validate assumptions, aiming for a scalable business model (maximizing the return on investment).
• Effectuation: Focuses on the "Affordable Loss" principle. You never risk more than you can personally afford to lose. You choose actions based on the downside risk you are willing to tolerate, rather than the potential upside.

4. Handling Unexpected Bad News

• Lean Startup: Uses a structured Pivot or Persevere decision point. If data disproves your hypothesis (e.g., via Maurya's Lean Canvas metrics), you systematically change your strategic direction.
• Effectuation: Uses the "Lemonade" principle. Instead of seeing negative data as a failure of a hypothesis, you view surprises as new raw materials. You actively leverage the unexpected to create a completely new opportunity you didn't plan for.

5. The Role of Partners and Competitors

• Lean Startup: Treats early adopters as a source of data. You keep your ideas flexible but generally protect your vision until you achieve Product-Market Fit.
• Effectuation: Uses the "Crazy Quilt" principle. You form partnerships with anyone who is willing to make a commitment to the venture, even if they aren't your ideal target. Whoever joins the quilt helps determine the ultimate direction of the company.

Summary Checklist

Sources of case study docs

Yes, there are several public lists and repositories of case studies written by Professor Sarasvathy and her academic co-authors. Over her career, she has written or contributed to more than 200 case studies. [1, 2]

You can access these case studies through two main archives, depending on whether you want academic/classroom materials or free narrative stories:

1. The Official Darden Business Publishing Store

For peer-reviewed, formal academic case studies and technical notes taught at the university level, you can browse the Darden Business Publishing Author Profile for Saras Sarasvathy. [3]

• What you'll find: Complete, purchaseable classroom cases, teaching materials, and pedagogical frameworks.
• Notable Technical Notes: Pieces like The Art of the Effectual Ask (examining how entrepreneurs form partnerships). [3, 4]

2. The Free Effectuation.org Repository

Professor Sarasvathy founded the global community platform Effectuation.org, which hosts an open archive of entrepreneurial case studies broken down by her 5 core principles. You can view these directly on the Effectuation.org Case Study Directory. [2, 5, 6]

Prominent, real-world case studies in this free directory include: [6, 7]

• The Ice Man Cometh: The story of Sweden's famous ICEHOTEL.

Are you looking for a case study on a specific industry (like tech, social enterprise, or retail), or do you need a case study that highlights a particular principle like the "Bird-in-Hand" or "Lemonade" principle?
