Rapid coding gets you started. The last 20% ensures you last.

In software development, speed can be thrilling. With modern code-generation tools and AI-assisted coding, teams can build a working prototype in hours instead of weeks. This rapid approach, often called vibe coding, can deliver 80 percent of your application in minutes. That early progress can be exciting, energizing, and convincing enough to show to stakeholders.
But the remaining 20 percent is where the real test begins. This part is slower, more complex, and critical for business survival. If ignored or rushed, it can lead to costly mistakes that outweigh the benefits of the fast start.

What Vibe Coding Does Well

Vibe coding shines in the early stages. It is perfect for:

• Building a basic user interface and core functions
• Creating simple data flows
• Demonstrating happy path scenarios where everything works perfectly
• Implementing prototype-level features for demos or validation

For example, imagine launching a demo version of an e-commerce app to pitch to investors. With vibe coding, you can show them a live shopping cart, a product list, and a payment screen in just a day. At this point, the goal is to validate the concept, not to withstand the load of thousands of daily shoppers.

The Final 20%: Where Complexity Lives

The last part of the journey covers areas that are often invisible to users but essential for success:

• Security and authentication mechanisms
• Data governance and privacy protections
• Error handling for every possible failure scenario
• Performance tuning for high-traffic situations
• Integration with existing systems or third-party services
• Compliance with legal and regulatory requirements

These are the features that transform a functional demo into a robust product. Without them, a system may work in the lab but fail in production. For example, a messaging app might handle 50 users flawlessly, but without proper scaling and error handling, it could crash under real-world traffic.

Enterprise Software is More Than Features

A prototype shows possibilities, but enterprise-grade software requires infrastructure that is stable, secure, and able to grow with the business. This includes load balancing, monitoring, automated testing, and disaster recovery plans. In short, features attract users, but infrastructure keeps them.

The Right Way to Use Vibe Coding

The most successful teams treat vibe coding as a tool for exploration and validation. They use it to test ideas, get quick feedback, and prove concepts. Once validated, they shift to building with resilience in mind, adding safeguards, optimizing performance, and meeting compliance needs.

The Risk of Skipping the Transition

Teams that fail to move beyond vibe coding often end up with software that looks polished but is fragile under pressure. This is a dangerous position, especially for products that aim to serve a large customer base or handle sensitive data.
