Capturing the full potential of agents will require modernizing enterprise architecture. By Pascal Gautheron, Chris Bell, and Stephen Hardy This article is part of Bain’s Technology Report 2025 Agentic AI isn’t just another wave of automation; it’s a structural shift in enterprise technology, one with the potential to completely redefine how work gets done. Previous waves of automation tackled parts of processes, leaving exceptions where humans had to step in. AI agents can reason, collaborate, and coordinate actions, allowing them to accomplish complex, multistep, nondeterministic processes that have so far depended on humans.

It’s easy to see the transformative potential of this, from improved operational efficiency and customer experience to sharper decision making and beyond. Forward-looking leaders aren’t asking if agentic AI will reshape their business but how to prepare their organizations to deploy it safely and effectively. As businesses navigate the fast-changing landscape of intelligent automation, many are placing their bets on the potential of agentic AI. A January 2025 Gartner poll of 3,412 webinar attendees, found that nearly one in five organizations have already made significant investments in this space. Another 42% are experimenting more cautiously, while some are still on the fence, unsure whether or how to dive in. But alongside this growing momentum, there’s a cautionary note: Gartner predicts that more than 40% of agentic AI projects will be canceled by the end of 2027.

[1] Why the disconnect between promise and performance? Often, it comes down to execution. Agentic AI isn’t something you can simply plug in and expect results, it requires a solid foundation, built on the right architecture. Without a clear framework and thoughtful design, even the most promising projects can fail. So what does a successful agentic AI architecture actually look like?

And how can organizations move from early pilots to real, enterprise-wide impact? Let’s take a closer look. Agentic AI architecture is the smart blueprint behind autonomous systems comprising AI agents that don’t just follow instructions, but think, decide, and act on their own, either solo or as part of a team. Unlike basic automation or simple AI tools that do one thing well, AI agents are built to handle changing situations, learn on the fly, and work together across different tasks and systems. This makes them a game-changer for businesses ready to embrace truly intelligent, adaptable solutions. Agentic AI architecture brings together many specialized AI agents into a well-orchestrated ecosystem.

Each agent can make its own decisions but also collaborates toward shared goals, balancing independence with alignment to the bigger objectives. Such an architecture combines the technological backbone, coordination tools, and safety measures needed to keep these agents running smoothly, reliably, and at scale. Stay ahead with BCG insights on digital, technology, and data Manage Subscriptions Today’s AI agents have the potential to revolutionize business processes across the board. Our experience shows that recent advances in computing power and the rise of AI-optimized chips can reduce human error and cut employees’ low-value work time by 25% to 40%—and even more in some cases. These agents work 24/7 and can handle data traffic spikes without extra headcount.

And the AI-powered workflows they create can accelerate business processes by 30% to 50% in areas ranging from finance and procurement to customer operations. AI agents are not just improving workflows; they’re redefining how businesses operate. Recent breakthroughs in deep learning, generative AI, and autonomous systems, augmented by a proliferation of enterprise data from digital devices and collaboration tools, have dramatically increased their ability to handle complex decision making in... As a result, these intelligent virtual assistants are transforming core technology platforms like CRM, ERP, and HR from relatively static systems to dynamic ecosystems that can analyze data and make decisions without human intervention,... But implementing these new agents is a complex process. It requires system interoperability, high-quality data, redesigned enterprise platforms, and agentic designs with the right level of autonomy, constraints, and goals.

To meet these challenges, BCG has developed a step-by-step playbook for agent-based workflow transformation. While both traditional workflow automation and agentic AI focus strongly on efficiency, AI agents are also capable of intelligence, adaptability, and continuous learning. They can take autonomous, goal-directed actions and process and optimize workflows at an unprecedented rate, without latency issues. AI is bringing the largest organizational paradigm shift since the industrial and digital revolutions (see sidebar, “The evolution of operating models”). This new paradigm unites humans and AI agents—both virtual and physical—to work side by side at scale at near-zero marginal cost. We call it the agentic organization.

This article is a collaborative effort by Alexander Sukharevsky, Alexis Krivkovich, Arne Gast, Arsen Storozhev, Dana Maor, Deepak Mahadevan, Lari Hämäläinen, and Sandra Durth, representing views from McKinsey’s People & Organizational Performance Practice, McKinsey... McKinsey’s experience working with early adopters indicates that AI agents can unlock significant value. Organizations are beginning to deploy virtual AI agents along a spectrum of increasing complexity: from simple tools that augment existing activities to end-to-end workflow automation to entire “AI-first” agentic systems. In parallel, physical AI agents are emerging. Companies are making strides in developing “bodies” for AI, such as smart devices, drones, self-driving vehicles, and early attempts at humanoid robots. These machines allow AI to interface with the physical world.

In the agricultural era prior to the 1800s, operating models were simple and centered around small teams of craftspeople and farmers. Eighty to 90 percent of the global population worked in agriculture.1Marian L. Tupy and Ronald Bailey, “The changing nature of work,” Human Progress, March 1, 2023. Next, in the industrial era, people moved into factories, and operating models shifted to functional hierarchies. Products were designed for mass replication by people and machines, with major upgrades every three to ten years. New roles emerged, such as factory workers, engineers, and shift supervisors.

By the 1970s, 39 percent of people in the United States worked in the industrial sector, with just 4 percent in agriculture.2Victor R. Fuchs, Economic growth and the rise of service employment, National Bureau of Economic Research working paper, number 486, June 1980. Efficient scaling drove companies’ growth and competitive advantage, and lean management became a strategic tool. For the last few years, most of the progress in AI has been tied to size. Bigger models, bigger datasets, bigger everything. And sure, that brought us a long way.

But as we head into 2026, it feels like we’ve hit a point of diminishing returns. Models keep getting larger and demo videos keep getting flashier, but that doesn’t translate into real operational value for most companies. The gap between “cool prototype” and “this actually runs our business” is still too wide. What is starting to move that line is the shift toward agentic AI. Instead of waiting for a prompt and producing a single answer, these systems operate more like persistent software components that chase a goal, react to new information, and adjust as they go. It’s a very different mindset from what we’ve been building toward over the last decade, and it requires us to rethink the architecture around AI – not just the models themselves.

Generative AI changed how people interact with computers, but the loop hasn’t changed much. You ask, it answers, and the conversation resets. Agentic systems don’t behave that way. They take in live data, watch for changes, make decisions, and revise them if things don’t play out as expected. Think of problems that don’t fit neatly into a single step: customer journeys that unfold over days or weeks, inventory levels that fluctuate by the hour, fraud patterns that evolve in real time. These aren’t “give me an answer once and I’m done” problems.

They’re ongoing loops. The surprising part is that the bottleneck isn’t the model. It’s the architecture around it. If an agent doesn’t have the right data, or the data doesn’t agree across systems, the agent ends up making the wrong call, quickly and confidently. As we advance deeper into 2025, agentic AI—systems capable of autonomous, goal-driven behavior—have transitioned from experimental prototypes to mission-critical enterprise tools. This evolution demands a rigorous reassessment of best practices for design, deployment, and governance.

Leveraging the latest generation of AI models such as GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5, organizations face both unprecedented opportunities and complex challenges in operationalizing agentic AI effectively and responsibly. Drawing upon recent research trends, industry benchmarks, and practical insights, this analysis provides a comprehensive framework for business leaders and technology strategists to understand, implement, and scale agentic AI systems with confidence. We focus on technical depth, deployment realities, and strategic imperatives essential for enterprises navigating the agentic AI landscape in 2025. At its core, agentic AI represents a confluence of autonomous reasoning, adaptability, and rigorous alignment with human values and operational boundaries. Unlike traditional AI assistants that react passively, agentic systems proactively pursue objectives, make contextual decisions, and dynamically adjust behavior based on evolving inputs. However, autonomy without alignment risks unpredictable or harmful outcomes.

The 2025 research consensus emphasizes embedding layered safety mechanisms and ethical guardrails directly into agentic AI architectures. This includes scenario simulation, continuous human-in-the-loop oversight, and fail-safe rollback capabilities. Such design choices ensure that agentic AI operates reliably within predefined constraints, maintaining trust and compliance. For business leaders, this means prioritizing AI solutions that do not merely automate tasks but do so transparently, with verifiable alignment to organizational policies and regulatory frameworks. The 2025 Artificial Intelligence and Business Strategy report, from MIT Sloan Management Review and Boston Consulting Group, looks at how organizations that are adopting agentic AI are gaining advantage while facing four distinct tensions. The research and analysis for this report was conducted under the direction of the authors as part of an MIT Sloan Management Review research initiative in collaboration with and sponsored by Boston Consulting Group.

Executives have long relied on simple categories to frame how technology fits into organizations: Tools automate tasks, people make decisions, and strategy determines how the two work together. That framing is no longer sufficient. A new class of systems — agentic AI — complicates these boundaries. These systems can plan, act, and learn on their own. They are not just tools to be operated or assistants waiting for instructions. Increasingly, they behave like autonomous teammates, capable of executing multistep processes and adapting as they go.

Notably, 76% of respondents to our global executive survey say they view agentic AI as more like a coworker than a tool. For strategists, agentic AI’s dual nature as both a tool and coworker creates new dilemmas. A single agent might take over a routine step, support a human expert with analysis, and collaborate across workflows in ways that shift decision-making authority. This tool-coworker duality breaks down traditional management logic, which assumes that technology either substitutes or complements, automates or augments, is labor or capital, or is a tool or a worker, but not all at... Organizations now face an unprecedented challenge: managing a single system that demands both human resource approaches and asset management techniques. The separation of technology and strategy inside most organizations exacerbates this challenge.
