Back to Basics Series – Principle 4

Business people and developers must work together daily throughout the project.

What Does It Mean?

When the Agile Manifesto was written back in 2001, this was a radical idea. Business and technology working together daily? For many organizations, those groups lived on opposite sides of the wall: business tossed requirements over, and IT tossed timelines back.

This principle is about tearing down that wall. It doesn’t say “once a month status update” or “quarterly alignment session.” It says daily. That’s how important collaboration is. Because when business and developers collaborate continuously, we don’t just build faster—we build the right thing.

My Experience

I’ve coached in organizations where this principle was ignored, and the result was predictable: business teams spent months dreaming up requirements, while developers built exactly what was asked—only to discover it wasn’t actually what the business needed.

I’ve also seen the opposite. In one case, a product team invited developers into every early-stage product conversation. Instead of being “order takers,” developers became creative partners. They brought up technical possibilities and risks early, saving weeks of rework later. The business side loved it because ideas got sharper faster, and developers loved it because they weren’t just building blindly.

It wasn’t always smooth—there were debates, even arguments—but the end product was far stronger.

Why This Matters

When business and developers collaborate daily:

• Assumptions surface sooner.
• Misunderstandings shrink.
• Trust grows.
• The product evolves in real-time to meet customer needs.

When they don’t:

• Requirements rot in documents.
• Developers become order processors instead of problem-solvers.
• Products miss the mark, even if they ship “on time.”

The truth is, daily collaboration isn’t about meetings. It’s about partnership. Agile isn’t just a delivery method—it’s a way of connecting business value with technical expertise in a continuous loop.

Take It to Your Team

Try this in your next retro:

• Ask: When was the last time business stakeholders and developers sat down together outside of a formal meeting?
• Explore: What’s stopping daily collaboration? (Time zones? Culture? Org structure?)
• Experiment: Pick one lightweight practice to bridge the gap—maybe a shared Slack channel, a daily 10-minute “business + dev sync,” or inviting business partners into sprint reviews more actively.

The principle isn’t about adding ceremony—it’s about removing walls.
