This essay provides an in-depth analysis of entrepreneurship, focusing on Sarasvathy's concepts of causation and effectuation. Causation involves selecting the best means to achieve a pre-determined effect, while effectuation entails choosing the most favorable effect based on available means. The essay contrasts traditional business ventures with modern entrepreneurial approaches, highlighting the shift from rigid, inflexible models to contingency-focused, innovative strategies. It explores how startups utilizing effectuation may face earlier failures but with lower investment risks, and emphasizes the importance of strategic alliances, exemplified by Uber and Spotify. The discussion also covers modern marketing tactics, short-term financial strategies, and the implementation of participative work environments, using Google as a prime example. Ultimately, the essay concludes that entrepreneurship is vital for global business growth, with new firms being more responsive, customer-led, and technologically advanced due to their networking and value-based offerings.
