From McKinsey’s Agentic AI Playbook to Real Workflows: ReplyFabric Is Where You Begin

McKinsey’s latest article on Agentic AI makes one thing crystal clear: incremental automation is not enough.
To unlock the next wave of value, businesses need to reimagine workflows—end-to-end, agent-first, and cross-functional.

But here’s the problem: CEOs and teams struggle to know where to begin. The concept of “rewiring an organization for agents” feels abstract and overwhelming. And yet, McKinsey’s message is urgent: waiting is riskier than starting small.

So what’s the obvious first move?

Start where work actually happens: the inbox

Your inbox isn’t just email—it’s the operating system of modern work.

• Customers reach out.
• Suppliers send contracts.
• Colleagues escalate problems.
• Deals, complaints, approvals—all flow through shared mailboxes.

If workflows are arteries, email is the blood. Which makes it the perfect starting point for Agentic AI.

ReplyFabric: the agentic foundation

ReplyFabric is an AI agent for shared inboxes. It:

• Categorizes emails with up to 95% accuracy.
• Drafts high-quality replies instantly, validated by AI and a human premium layer.
• Routes messages to the right people or processes.
• Works seamlessly across Outlook, Gmail, and multilingual teams.

It’s not a gimmick—it’s agentic workflow automation, right where bottlenecks live today.

The Four Levels of Agentic Systems (McKinsey Framework)

The McKinsey chart shows how agentic systems evolve from basic task helpers to handling increasingly complex tasks, eventually powering full cross-functional engines.

Here’s a breakdown with real numbers from the article:

1. Individual augmentation

   • Agents help automate simple tasks like summarizing meetings or drafting code.
   • Impact: 20–30% higher personal throughput in single-task areas such as programming.

2. Task and workflow automation

   • Agents automate repetitive, transactional workflows (e.g., contact center requests).
   • Impact: 20–40% faster cycle times or lower handling costs for repetitive tasks.

3. Functional agentic workflows

   • Teams of agents redesign processes within a function, such as financial planning or customer care.
   • Impact: In call centers, 60–80% of incoming requests could be automated while maintaining or improving customer satisfaction.

4. Cross-functional agentic systems

   • Agent-native systems manage entire journeys across functions (e.g., loan approvals, insurance claims).
   • Impact: Early pilots showed 70–80% reductions in cost per transaction for labor-heavy processes.

💡 Where ReplyFabric Fits In
ReplyFabric sits between Level 2 and Level 3:

• At Level 2, it automates repetitive inbox workflows like categorization, drafting replies, and routing messages—delivering the same 20–40% faster cycle times McKinsey highlights.
• But it also nudges into Level 3 by enabling functional workflows: for example, turning customer support inboxes into agentic systems that resolve a majority of issues without human escalation.

In short: ReplyFabric isn’t just email automation—it’s the first real step toward agent-native workflows.
