A lot of companies started with a chatbot. And many were genuinely surprised by how much that alone changed things – fewer repetitive questions to the team, faster answers to standard requests, staff freed up for work that actually requires human judgment. That's not a small win. That's real, daily relief.
Agentic AI builds directly on that foundation – and takes it a meaningful step further.
What Chatbots Already Deliver
A well-configured chatbot is not a toy. According to McKinsey's 2025 State of AI report, 88 percent of surveyed companies already use AI in at least one business function productively – and the most common starting point was exactly this: AI-assisted communication and knowledge access (McKinsey State of AI 2025).
What chatbots concretely take off your plate:
- Answering standard questions from customers or employees around the clock
- Making content from manuals, policies, or documents instantly accessible
- Doing a first pass on incoming requests before a human steps in
- Walking users through simple forms and processes directly in conversation
This saves measurable time. Not a promise – a pattern confirmed across sectors and company sizes.
What Agentic AI Does Differently
A chatbot answers. An AI agent acts.
The difference isn't intelligence – it's autonomy. An agent receives a goal and decides on its own what steps are needed to reach it. It calls APIs, reads documents, enters data, sends notifications, and checks its own results. After each step, it evaluates whether it's on track and adjusts its plan accordingly.
As Red Hat explains, agentic AI combines the language capability of a large language model with real automation: the model plans, the automation executes. Traditional rule-based workflows can only do what was explicitly programmed. An agent handles deviations – missing fields, unexpected responses, unstructured emails – without breaking.
Where AI Agents Are Running in Production Today
Use cases already active in real business environments (Boomi, 2025; UiPath, 2025):
- Document processing: Automatically reading, classifying, and routing invoices, contracts, and delivery notes – no manual data entry
- Customer communication: Resolving standard cases directly, handing off complex ones with full context to staff
- Internal knowledge access: Employees query policies, manuals, or technical docs and get direct answers instead of search results
- Automated reporting: Pulling data from multiple systems, formatting it, and sending scheduled reports
- Operational coordination: Inventory monitoring, automatic order triggers, autonomous supplier queries
A Forrester Total Economic Impact study commissioned by Boomi found a 347 percent ROI over three years for the Boomi platform (Forrester TEI, 2025). The study covers the full platform including automation and integration capabilities – not an agentic-AI-only figure, but a meaningful reference point for what structured automation projects can deliver.
Six Lessons from McKinsey's 50+ Real Deployments
McKinsey analyzed over 50 of their own agentic AI projects and published six key findings (McKinsey, September 2025):
- Redesign the process first: Value comes from rethinking the workflow, not just deploying an agent into an existing one.
- Build modular: Reusable components reduce development effort for new use cases by 30 to 50 percent.
- Invest in evaluation: Teams that skip regular quality checks only discover mistakes once they're expensive.
- Log every action: Essential for debugging, compliance, and building internal trust.
- Keep humans in the loop: For edge cases and high-stakes decisions, human oversight isn't a limitation – it's good system design.
- Set clear goals: ROI comes from defined intent, not experimentation for its own sake.
How to Start – Without Overcomplicating It
The good news: you don't need to start big. A well-built internal knowledge chatbot is a fully valid first step – and often the fastest way to build confidence in AI systems within your own team before expanding scope.
For anyone thinking further ahead: the EU AI Act has been binding for AI model providers since August 2025. Full obligations for high-risk systems – AI used in HR decisions, critical infrastructure, or law enforcement contexts – apply from August 2026 (EU AI Act Service Desk). For most operational use cases, that translates to: documentation, transparency, and demonstrable human oversight.
At Bley IT in Tübingen, we start with a process analysis: where does manual work consume the most time? Which workflows have structured – or structurable – inputs? From that, we build a proof of concept that shows within a few weeks whether the approach holds for your specific situation, before any larger investment follows.
