AI and Technical Debt: Balancing Innovation and Sustainability

Learn how to navigate technical debt in AI projects, balance rapid adoption with long-term sustainability, and implement best practices for successful AI initiatives.



As artificial intelligence (AI) continues revolutionizing the tech industry, developers, engineers, and architects face a new challenge: managing the technical debt of rapid AI adoption. Jeff Hollan, Head of Apps and Developer Tools at Snowflake, shares invaluable insights on balancing innovation and sustainability in AI projects.


The AI Adoption Dilemma

The rush to implement AI solutions has created a unique landscape where organizations must carefully navigate between seizing opportunities and avoiding potential pitfalls. As Hollan points out, 

"There's a lot of activity and urgency around AI and AI's potential in organizations. Every organization I talk to about their data or their application strategy always brings up: Well, how do we incorporate AI? Where can AI help us?"

While driving innovation, this urgency also contributes to the accumulation of technical debt. Hollan explains, "Because there's this urgency, there's this need to see something. Let's try to add some good right now. That means there's debt being accumulated."


Understanding AI-Specific Technical Debt

Technical debt in AI projects often manifests differently than in traditional software development. Hollan identifies a key area of concern: 

"The one that is unique to AI is in this realm of quality control or testability before production."

Unlike conventional systems where logic can be easily tested, AI models present unique challenges. "When you get these sophisticated AI models, it starts to feel a lot more like what are the systems? What processes would you put in place to ensure that an intern, a college graduate, or a junior employee can't get themselves into trouble?" Hollan explains.


This uncertainty in output and behavior makes it crucial for organizations to implement robust safeguards and protections, especially for customer-facing applications.


Strategies for Managing AI Technical Debt

1. Empower Exploration and Learning

Hollan advocates for a balanced approach: 

"You need to empower your organization to be able to do some exploration and learning, to wrap their heads around the type of use cases where AI today can really help us."

This exploration phase is critical for understanding where AI can be most effectively applied and where it might not be ready for prime time.


2. Build on Platforms, Not Point Solutions

One of the most effective strategies for mitigating technical debt is to build on comprehensive platforms rather than piecing together multiple-point solutions. Hollan warns against the "flavor of the week" approach:

"They have one team who's going in exploring platforming, another team who's like, oh, we just saw this really cool announcement. Let's go spin up this other thing on Platform B. And pretty soon, they struggle to build a cohesive set of best practices because they have distributed so many of their investments across so many different pieces."

Organizations can limit variables and maintain a more cohesive development ecosystem by focusing on unified platforms.


3. Implement Robust Quality Control

Hollan emphasizes the importance of quality control in AI applications: 

"The best practice is the having the AI show its work."

This means ensuring a clear trail of how the AI arrived at its conclusions, either directly visible to the user or through comprehensive logging and observability tools.


"Make sure there is a trail directly to the user or at least logs through observability tools. You need to understand this is the source of truth," Hollan advises.


4. Prioritize Security From the Start

One common pitfall in AI adoption is neglecting security considerations in the rush to implement new solutions. Hollan cautions, 

"It becomes very easy to think about security last. You can very quickly get a very cool AI proof of concept up and running. And then there's a bunch of hand waving where you're like, we'll figure out how to make this secure. Do not do that."

Instead, he recommends addressing security questions upfront to avoid potentially costly retrofitting later.


Measuring ROI and Making Informed Decisions

As organizations invest in AI, it's crucial to effectively measure the return on investment (ROI) while considering both short-term gains and long-term sustainability. Hollan shares an example of a successful approach:

"A recent customer who I spent a few hours with the other week comes to mind. They spun up over the course of three months, three specific AI investments. After those investments, they did have a period of evaluation to identify what they were able to achieve from a technology standpoint."

This strategic pause allowed the organization to assess the technical viability and actual business outcomes. As a result, they decided to proceed with two of the three initiatives, shelving the third. This approach demonstrates the importance of focused, strategic investments in AI rather than a scattershot approach.


The Role of MLOps in AI Application Lifecycle

When managing AI-powered applications throughout their lifecycle, Hollan sees MLOps practices as essential: "Hand in glove like this is a super important piece of it." While the specifics of model development may vary depending on whether organizations are using off-the-shelf AI services or developing custom models, the principles of MLOps remain crucial.

"All the other principles around ML ops, things like detecting drift and quality and accuracy and having stories where you can deploy multiple versions of models and test things out. Those patterns are going to be just as applicable for AI as they have been for traditional ML,"Hollan explains.

Future-Proofing AI Implementations

To ensure AI implementations remain scalable and maintainable as technology evolves, Hollan recommends focusing on areas of standardization:

"I recommend developers look at areas where there is standardization happening. What I mean by that are like centers of gravity, where you see a lot of innovation happening. So for instance, I when I do AI development, I am often using libraries like LangChain or LlamaIndex or things in like; there's five or ten of these that are fairly mainstream."

By leveraging these abstraction layers, developers can build more resilient applications better protected against the rapid changes in underlying AI technologies.


Advice for Teams Starting Their AI Journey

For development teams embarking on their AI journey, Hollan offers a mix of optimism and pragmatism:

"Be very optimistic about AI and the potential of AI. That doesn't mean it's going to be straightforward. You're 100% going to hit areas where, like, oh, you know what? The demo was super easy to build, but you quickly find out the limitations as well."

He encourages teams to maintain a balanced perspective, understanding both AI's transformative potential and its current limitations. "Have a bit of optimism and practicality. Don't get discouraged. Go through the first iteration and see how far you've come. Keep evolving and iterating on it."


Conclusion

Managing technical debt becomes increasingly crucial as AI reshapes the software development landscape. By adopting a strategic approach that balances rapid innovation with long-term sustainability, organizations can harness the power of AI while avoiding the pitfalls of unchecked technical debt.


Remember, the key lies in empowering exploration, building robust platforms, implementing substantial quality control and security measures, and clearly focusing on business outcomes. With these principles in mind, developers, engineers, and architects can lead their organizations into a future where AI drives innovation without compromising sustainability.
