The Art of Engineering Efficiency: Avoiding the Wheel Reinvention Trap

Recently, last weekend, I meet an old friend, Arjun (changed name), who also happened to be a technologist working for a prominent product company. Our conversations usually revolved around the latest tech trends and the exciting projects we were working on. Little did I know that this particular meeting would shed light on a common pitfall in the world of engineering.

After catching up on life's updates, we naturally drifted towards our shared passion for technology. Arjun shared an intriguing development at his company - they had successfully migrated their services from traditional HTTP to the more efficient GRPC protocol. This strategic move not only resulted in substantial cost savings but also unlocked remarkable performance benefits.

As Arjun continued sharing his achievements, he mentioned the extensive proof-of-concept (POC) his team had conducted to compare the performance of GRPC and HTTP. The POC, however, had consumed a few weeks of their time.

Curiosity piqued, I couldn't help but ask, "Was it truly necessary to spend weeks comparing GRPC and HTTP? Isn't it widely known that GRPC offers a significant performance advantage over HTTP? Isn't it established that GRPC reduces data transfer by a substantial percentage compared to its predecessor?"

These questions were not intended to undermine the team's efforts but rather to understand the rationale behind such a time-consuming endeavor. From my perspective, it seemed like reinventing the wheel, especially since this specific POC was not contingent upon unique business requirements. It merely involved evaluating performance under a given load and response size, with results that were already widely available.

In response to my queries, Arjun paused for a moment, realizing the weight of my words. "You bring up a valid point," he conceded. "In hindsight, we could have leveraged the industry's existing knowledge and standards to guide our decision-making instead of reinventing the wheel through this exhaustive POC."

Together, we explored the implications of reinventing the wheel in engineering. While innovation and experimentation are crucial elements of progress, there are instances when existing knowledge and best practices should be heeded. In this case, the overwhelming evidence pointing to GRPC's superior performance could have informed their decision without the need for an extensive POC.

We discussed how the team could have redirected their valuable time and effort to more productive areas. Rather than reinventing the wheel by comparing known performance benchmarks, they could have focused on the key challenges associated with migrating from HTTP to GRPC. This would have allowed them to plan the necessary changes and identify the components requiring replacement or adjustment in the process.

As our conversation drew to a close, Arjun and I concluded that the real essence of engineering effectiveness lies in striking a delicate balance between exploration and leveraging existing knowledge. While it is essential to push boundaries and seek innovative solutions, we must also recognize when established standards can guide us more efficiently.

In our ever-evolving technological landscape, it is crucial to discern between reinventing the wheel and making meaningful progress. By avoiding unnecessary duplication of efforts and tapping into collective wisdom, engineers can optimize their effectiveness and channel their skills towards solving complex problems and driving true innovation.

So, the next time you find yourself facing a challenge, pause for a moment and consider whether you are reinventing the wheel. Look for existing knowledge and proven solutions that can help guide your path. Embrace the art of engineering efficiency and let it propel you towards greater success.

Remember, progress is not just about making something new; it's also about making something better.
