4. The Zombocom Problem
Total comment counts : 19
Summary
The article discusses the Zombocom Problem, which highlights the challenge many software solutions face when trying to be overly flexible or universal without addressing specific needs first. Here’s a summary:
Zombocom: An analogy for platforms or software that promise unlimited potential but fail because they lack specificity in solving real-world problems.
Amazon Example: Initially, Amazon focused on selling books, which was a strategic choice because books offered a vast catalog size not feasible in physical stores. This specificity allowed Amazon to establish itself before expanding into other product categories, eventually becoming the “everything store.”
Spreadsheets and VisiCalc: The success of spreadsheets like VisiCalc is attributed to targeting a specific user group (small business owners who couldn’t afford full-time accountants) before becoming ubiquitous in various industries.
Product vs. Platform: The article advises against starting with the intention of building a platform; instead, one should focus on creating a great product that solves a specific problem. Platforms should evolve from successful products.
Building Software: The author suggests starting with a systems-level insight (like the rapid growth of the internet) and then identifying a ‘first best customer’ with a specific need. This approach avoids the pitfalls of both overly narrow product focus and overly broad platform ambitions.
Conclusion: To avoid the Zombocom trap, software should begin with a clear, specific use case, allowing for organic growth and eventual platform development if the initial product meets a real need effectively.
