AI Use Cases by Business Function
How to Look Like a Visionary (Without Actually Being One)
You're in a meeting. Someone says "We should use AI for this." Everyone nods. No one knows what "this" means. Sound familiar?
Welcome to business in 2025, where "AI strategy" is mandatory but "knowing what AI actually does" is optional. Let's fix that.
The Reality Check
Bad approach: "Let's use AI for everything!"
Good approach: "Let's use AI for specific problems where it actually helps."
AI isn't magic pixie dust you sprinkle on your business. It's a tool. You wouldn't use a hammer to fix a software bug (probably), so don't use AI where it doesn't make sense.

Common Mistakes to Avoid
Mistake 1: AI for Everything
- Don't use AI where simple automation works fine
- Example: You don't need AI to send a welcome email
Mistake 2: No Clear Owner
- AI projects need someone responsible
- "Everyone's job" = "No one's job"
Mistake 3: Ignoring Change Management
- Your team needs to actually use the AI tool
- Training and buy-in are crucial
Mistake 4: Expecting Perfection
- AI is 80-95% accurate, not 100%
- Plan for human review
Mistake 5: No Success Metrics
- Define what success looks like before starting
- "We'll know it when we see it" doesn't work
Your AI Use Case Action Plan
Week 1: Identify Pain Points
- Talk to each department
- List top 3 time-consuming tasks
- Identify repetitive work
Week 2: Research Solutions
- Google "[your problem] + AI solution"
- Check what competitors use
- Read case studies
Week 3: Pilot Test
- Start small with one use case
- Set clear success metrics
- Get feedback from users
Week 4: Measure & Iterate
- Did it work?
- What needs improvement?
- Should you scale or pivot?
The Bottom Line
AI isn't about replacing humans - it's about freeing humans from boring, repetitive work so they can do the interesting stuff. The best AI use cases are the ones where everyone says "Why didn't we do this sooner?"
Start with one clear problem, measure the results, and expand from there. You don't need a massive AI transformation. You need one win that proves the value.
Then your boss will think you're a genius. And technically, you kind of are.
