How do entrepreneurs make strategic choices when the future is unknowable and resources are scarce? This question sits at the heart of entrepreneurial strategy, a subfield that emerged at the intersection of entrepreneurship and strategic management. Early answers borrowed heavily from corporate strategy: set goals, analyze markets, and execute a plan. But a growing body of research argued that entrepreneurs operate under conditions that make such predictive logic unreliable. The frameworks that followed—spanning from the late 1980s to the present—can be understood as an evolving debate between two competing logics: one that seeks to measure and manage entrepreneurial posture through planning, and another that embraces non-predictive action, resourcefulness, and iterative experimentation.
The first systematic attempt to bring strategy into entrepreneurship was Entrepreneurial Orientation (EO) . Developed by Danny Miller and later refined by Covin and Slevin, EO treated entrepreneurship as a firm-level posture characterized by three dimensions: innovativeness, proactiveness, and risk-taking. Rather than asking what entrepreneurs do, EO asked how established firms could behave entrepreneurially. It provided a measurable scale that linked strategic posture to performance, making it a durable empirical tool. Over time, EO narrowed toward corporate contexts, where it remains widely used to assess how organizations sustain entrepreneurial behavior. Yet EO said little about how opportunities are discovered or exploited—it described a posture without explaining the strategic logic behind it.
Strategic Entrepreneurship (SE) , formalized by Ireland, Hitt, and Sirmon in 2001, directly addressed that gap. SE argued that entrepreneurial success requires simultaneously identifying opportunities and building competitive advantage—two tasks that earlier frameworks had treated separately. EO provided a posture, but SE supplied a process: entrepreneurs must orchestrate resources to exploit opportunities while protecting the value they create. This framework absorbed EO’s dimensions into a broader resource-based logic, emphasizing that entrepreneurial action must be strategically managed. Over time, SE has been increasingly absorbed into the dynamic capabilities literature, which focuses on how firms reconfigure resources in changing environments. SE remains influential in corporate entrepreneurship and strategic management, but its predictive, planning-oriented assumptions left it open to challenge.
In the same year that SE appeared, Saras Sarasvathy introduced Effectuation theory, a radical departure from predictive logic. Based on studies of expert entrepreneurs, effectuation argues that when the future is unpredictable, entrepreneurs do not set goals and then acquire resources. Instead, they start with who they are, what they know, and whom they know, then co-create opportunities with stakeholders. The core principles—affordable loss rather than expected return, partnerships rather than competitive analysis, and leveraging contingencies rather than avoiding them—rejected the planning-centric assumptions of both EO and SE. Where SE treated uncertainty as something to be managed through resource orchestration, effectuation treated it as a resource to be exploited through control. This non-predictive logic became a foundational alternative, especially in entrepreneurship pedagogy.
Bricolage theory, introduced by Ted Baker and Reed Nelson in 2005, shared effectuation’s skepticism toward resource planning but focused on a different problem: how entrepreneurs act when they lack the resources that strategic frameworks assume. Bricolage means “making do with what is at hand”—recombining existing materials, skills, and relationships to create new value. While effectuation emphasizes stakeholder co-creation and control, bricolage emphasizes resourcefulness and improvisation in resource-constrained environments. The two frameworks complement each other: effectuation provides a decision-making logic, while bricolage explains the material practices that make that logic work. Both stand in contrast to SE’s resource-orchestration view, which assumes that entrepreneurs can acquire or build resources through planning.
Lean Startup methodology, popularized by Eric Ries in 2011, translated the non-predictive insights of effectuation and bricolage into a repeatable, teachable process. Its core cycle—build-measure-learn—operationalizes effectual experimentation: instead of writing a business plan, entrepreneurs test hypotheses through minimum viable products and pivot based on feedback. Lean Startup also absorbed bricolage’s emphasis on resource efficiency by advocating for “validated learning” over elaborate upfront investment. However, Lean Startup narrowed the non-predictive logic by focusing primarily on product-market fit in digital and technology ventures, often downplaying the stakeholder co-creation and contingency-leveraging that effectuation emphasizes. It remains the most widely adopted practical methodology in entrepreneurship education and startup accelerators, coexisting with effectuation as a more structured, hypothesis-driven variant.
Business Model Innovation (BMI) , which gained prominence around 2001 through the work of Amit and Zott, took a different path. Rather than focusing on decision-making logics or resource practices, BMI asked how entrepreneurs design the architecture of value creation and capture. A business model is not a plan but a system of activities—how the venture creates value for customers, how it captures revenue, and how it organizes partners and resources. BMI complemented SE by providing a concrete design tool for the “advantage” side of the opportunity-advantage equation. It also offered a bridge to effectuation: entrepreneurs can co-create business models with stakeholders rather than imposing a pre-designed plan. Today, BMI is used as a design lens in both startups and established firms, overlapping with Lean Startup’s emphasis on iteration but focusing on the structural logic rather than the experimentation process.
The six frameworks remain active, but they now occupy distinct niches. Entrepreneurial Orientation and Strategic Entrepreneurship are primarily empirical tools for studying corporate entrepreneurship and firm performance; they assume that planning and resource orchestration are viable under moderate uncertainty. Effectuation theory thrives as a pedagogical logic for teaching entrepreneurial decision-making under high uncertainty, especially in early-stage ventures. Bricolage theory is used to explain resource-constrained innovation in emerging economies and social entrepreneurship. Lean Startup has become the default methodology for technology startups, often combined with business model canvases. Business Model Innovation serves as a design lens for both startups and corporate innovation.
What do these frameworks agree on? All recognize that uncertainty is the defining condition of entrepreneurship, and that strategic choice matters—entrepreneurs are not simply reacting to environments. They disagree on whether entrepreneurs should try to predict and plan (EO, SE) or control and experiment (Effectuation, Lean Startup, Bricolage). A growing consensus favors contingency: the appropriate logic depends on the stage of the venture, the nature of the opportunity, and the entrepreneur’s experience. The field has moved from a single best way to a pluralistic toolkit, where frameworks are combined rather than replaced. This pluralism is itself the central insight of entrepreneurial strategy: under uncertainty, the most strategic choice may be knowing which logic to apply.
