Navigating the AI toolbox: Choosing the appropriate AI tool for the job

Talking points

• While Generative AI (GenAI) simulates reality, it should not be the default tool for every reality-focused business task.
• Pairing AI with purpose-built tools and human capabilities can increase AI’s reliability and reduce inaccuracy.
• Survey data shows that AI deployment is rising, transformation is still uneven, and agentic AI holds promises for improving value if governance keeps pace.

As an Audit & Assurance (A&A) partner and digital products leader, I focus on audit and accounting transformation—including applying artificial intelligence (AI) to real-world accounting challenges. But at home, I’m a part-time, overly optimistic tinkerer. Over the years, that’s meant flooded kitchen floors, boat oil caps sinking into lakes, and the occasional minor electrical mishap. I’ll try to fix anything once, and eventually I get it right—but usually after relearning the same lesson: Use the appropriate tool for the job.

That same principle applies to today’s Generative AI (GenAI) environment. Many AI systems are positioned as universal interfaces—which means having just one tool for every job. This gets challenging because, fundamentally, a generative model is a simulation engine. It isn’t directly connected to objective reality; it only simulates reality by reconstructing patterns from data it has seen. These simulations simplify complex systems by approximating them, which is useful and necessary. But being untethered from reality sometimes results in inaccuracy.

AI versus purpose-built tools

This brings us to the point of this blog: Just because you have a fast and powerful AI model doesn’t mean it’s aways the appropriate tool for the job. That’s because not every activity needs a digital simulation. In many cases, a simpler technology is more reliable: a calculator for arithmetic, a structured database for data storage and retrieval, or a deterministic workflow for verification.

The challenge ahead for professionals navigating complex technological environments is sifting through a host of tools and choosing the one most suitable for the job, instead of defaulting to a simulation interface for every task. Reducing inaccuracy isn’t about making generative models do everything—it’s about placing them where they can add value, while relying on available purpose-built systems for what they are intended to do. That’s how you get precision, consistency, and trustworthy outcomes.

How companies can transform to better harness AI

On that point, the results of a recent Deloitte AI survey, published in January in our new report, State of AI in the Enterprise, highlight the successes and challenges companies are seeing with their AI efforts. The survey captures insights from more than 3,200 business and IT leaders around the world with direct involvement in their companies’ AI initiatives.

What did the study say about the rapidly evolving AI toolbox? It found that many companies are still at the cusp of large-scale AI-driven transformation. More than one-third (37%) use AI only superficially, with little or no change to existing operations.¹ That suggests they’re layering AI onto legacy processes rather than redesigning work to leverage the strengths of humans, AI, and other technologies. In short, they’re using AI in a one-size-fits-all manner instead of choosing the appropriate tool for each task.

The rise of agentic AI

Fortunately, rapidly emerging agentic AI, a more flexible and autonomous level of the technology, could help accelerate lagging transformation and unlock greater AI value. Today, 23% of companies use agentic AI at least moderately.² Within two years, adoption is expected to become widespread, with 74% using it at least moderately and 23% extensively.³ However, adoption is outpacing governance and oversight, which will need to speed up to keep pace. It is worth noting that, here too, technology is the tool that requires smart vision and application to deliver the intended impact and results.
