McKinsey on Agentic AI: Six Lessons That Shape ReplyFabric

A year into the agentic AI revolution, McKinsey has one clear message: success doesn’t come from building shiny agents alone—it comes from redesigning workflows and making humans and AI collaborate seamlessly.

At ReplyFabric, we couldn’t agree more. Shared inboxes like support@ or info@ are complex, time consuming workflows. They’re filled with categorization, prioritization, drafting, and validation steps—exactly the type of high-variance processes where agentic AI can shine if built the right way. McKinsey analyzed over 50 agentic AI builds and shared six lessons. Here’s how we’re putting them into practice:

---

1. Workflow beats agent

McKinsey: Too many companies obsess over agents but forget to fix workflows.
ReplyFabric: We started with the inbox workflow itself. From categorization to drafting and validation, we orchestrate the full flow so teams actually feel the productivity gains.

---

2. Not every task needs an agent

McKinsey: Some jobs are better handled by rules or automation.
ReplyFabric: Exactly. That’s why our platform allows filters and rules before AI kicks in. Newsletters? Archive. Customer requests? AI + Human in the Loop.

3. Stop “AI slop”

McKinsey: Poor outputs destroy trust.
ReplyFabric: Our dual-layer validation prevents sloppy drafts from reaching customers. Agents are trained like employees—with onboarding, feedback, and continuous improvement.

---

4. Track and verify every step

McKinsey: Observability is key when scaling agents.
ReplyFabric: Every reply can be traced, verified, and corrected. That transparency builds confidence in teams and customers alike.

5. Reuse beats one-off agents

McKinsey: Redundant agents waste time and money.
ReplyFabric: We reuse building blocks—categorization, sentiment detection, RAG lookups—across inboxes and languages. One foundation, many outcomes.

---

6. Humans remain essential

McKinsey: People still matter for compliance, judgment, and edge cases.
ReplyFabric: This is our Human in the Loop philosophy. In 99% of cases the draft is sent in seconds without edits, but that 1% human correction makes the difference. That’s the Human Premium.

👉 The bottom line? McKinsey’s six lessons are not abstract theory—they’re the blueprint for ReplyFabric. By aligning with these principles from day one, we’re not just deploying agents; we’re fixing email workflows, restoring trust, and letting teams shine again.
