The Key Factors for Success as a Product Manager: Connecting New Skills, Network Effects, and Defensibility

Introduction:
Being a successful product manager requires a combination of various skills, the ability to navigate trade-offs, and a deep understanding of the factors that contribute to a product's success. In this article, we will explore the commonalities between the concepts of "プロダクトマネジャー" (Product Manager) and "The Network Effects Manual," and delve into actionable advice for aspiring product managers.

The Power of Network Effects:
Network effects play a crucial role in creating defensibility in the digital world. Companies that incorporate strong network effects into their business models tend to emerge as winners and dominate their respective markets. A three-year study reveals that network effects have been responsible for 70% of the value created by tech companies since the advent of the Internet in 1994. Out of the four remaining defensibilities in the digital age, including brand, embedding, and scale, network effects have proven to be the most powerful.

Understanding Network Effects:
Contrary to popular belief, network effects are not synonymous with viral effects. While viral effects focus on acquiring new users for free, network effects concentrate on creating defensibility. The strength of network effects lies in the direct increase in a product's value to its users as its usage increases. This value cannot easily be replaced by a better product, making it challenging for new entrants to replicate the same level of value for their users. This exponential increase in network value is known as Reed's Law, which supersedes Metcalfe's Law.

The Longevity of Network Effects:
Once a network protocol gains widespread adoption, it becomes exceedingly difficult to replace. Examples like the continued use of the fax protocol and TCP/IP protocol showcase the endurance of established network effects. Joining a network where people from the real world already interact enhances the value for new users, as it serves as a hub for their identity and reputation. Personal Utility Networks, which are primarily used for practical tasks and private communication, provide substantial utility to users.

Marketplaces and Platforms:
Marketplaces and platforms leverage network effects to aggregate users and create value for both buyers and sellers. By co-locating competing sellers, marketplaces enable them to attract more business, making it challenging for others to compete. However, multi-tenanting poses a vulnerability to both marketplaces and platforms. To maintain defensibility, these platforms must design their products or services to offer enough value or "lock-in" to prevent members from seeking alternatives.

Different Types of Network Effects:
There are various types of network effects, each with its unique characteristics. Asymptotic Marketplaces, for example, are more susceptible to competition than other marketplaces. Data Network Effects occur when a product's value increases with more data, and additional usage yields valuable insights. Tech Performance nfx provide a runaway advantage for being the first in the market with a particular technology. Social nfx leverage psychology and interactions between people, making them challenging to deploy for long-term defensibility. Belief nfx gain strength as more people hold the same beliefs, while Bandwagon nfx rely on social pressure and the fear of missing out (FOMO).

Actionable Advice for Product Managers:

1. Embrace Continuous Learning: As a product manager, continually acquiring new skills and knowledge is crucial. Stay updated with industry trends, attend conferences, and engage in professional development opportunities to enhance your skill set.

2. Prioritize Defensibility: Understand the importance of incorporating network effects and other defensibilities into your product strategy. Consider how your product can create value for users and build barriers to entry for competitors.

3. Foster Collaboration and Communication: Effective product management requires strong leadership skills and the ability to collaborate across multiple disciplines. Foster an environment that encourages open communication, collaboration, and knowledge sharing among team members.

Conclusion:
Becoming a successful product manager requires a diverse skill set, an understanding of network effects, and the ability to create defensibility in a fast-paced digital landscape. By incorporating continuous learning, prioritizing defensibility, and fostering collaboration, aspiring product managers can increase their chances of success. Remember, network effects are not just about acquiring new users, but about creating long-term value and maintaining market dominance.
