Developers solve problems, while engineers anticipate problems. The key to engineering is to focus on what can go wrong, not just what can go right. This approach, although seemingly negative, is actually vital to building reliable and resilient systems. Thinking about potential failures and designing for them is what sets engineering apart from mere development. It’s not about being perfect, it’s about being pragmatic and learning from real-world failures. This engineering mindset is essential for creating better software. π·π§π
The Difference Between Developers & Software Engineers
π οΈ Developing an Engineering Mindset
π§ The Shift in Focus
The key behavior that distinguishes software engineering is a shift in focus from what happens when everything works as expected to actively thinking about what could possibly go wrong. This change in mindset, recognized by Margaret Hamilton, is crucial to the approach of all kinds of engineering.
π The Importance of an Engineering Mindset
This focus on what can go wrong is a mental tool that can be used to improve the quality of things built in the field of engineering, including software systems. It prompts engineers to think about potential failures and hazards during the design and development process.
π Practical Application
When tasked with building a bridge, for example, an engineer will actively imagine potential failures, such as the bridge collapsing under load or wobbling excessively in the wind. Similarly, in software development, the tendency to focus solely on solving the problem at hand and not considering possible failure points is not enough to be considered true engineering.

π₯οΈ A Lesson in Software Engineering
A simple but poorly-engineered software program called ‘A’ resulted in chaos when run by an unsuspecting colleague. The oversight of not actively thinking about potential risks led to costly consequences. This highlights the importance of an engineering mindset even in everyday programming tasks.

π‘ Practical Engineering Principles
Thinking about failures and actively exploring potential pitfalls is fundamental to good engineering. This not only applies to how software systems function internally but also how they interact with the outside world. Integrating fail-safes and considering user behavior are crucial aspects of engineering thinking.

π The Legacy of Engineering Thinking
Margaret Hamilton’s team’s approach to engineering was fundamental to the success of the Apollo program. They explicitly thought about potential failures and actively sought to eliminate them, ultimately resulting in an error-free flight control system throughout the entire program.
π A Lasting Philosophy
Thinking about potential failures and building systems to handle them is not about seeking perfection but about pragmatic problem-solving. This philosophy is often overlooked in software development but is crucial in creating resilient and reliable systems.
Conclusion
In summary, the distinction between software developers and engineers lies in the active mindset of considering potential failures and building systems to handle them. This approach, as exemplified by Margaret Hamilton’s team, is fundamental to good engineering and is a philosophy that should be embraced in software development. By actively exploring potential failures and designing systems to be resilient, engineers can bring immense value to software projects.
π Key Takeaways
- Engineering mindset focuses on actively considering potential failures rather than solely on solving problems.
- Fail-safes and user safeguards are essential aspects of engineering thinking in software development.
- The philosophy of actively seeking potential failures and building resilient systems is crucial for creating robust software.
