Confession: I Used to Think Specs Were Everything. Agile Broke Me (and Made Me Better)

When I started out as a BA, we were taught to treat documentation like gospel. But in an Agile world, usefulness doesn’t come from a polished doc. What they needed was me, in the room, talking with them.

There was a time I believed that if I just wrote a perfect spec—everything would go smoothly.

\ The devs would build exactly what I envisioned.

\ QA wouldn’t miss a thing.

\ The product owner would nod in agreement, and we’d launch on time.

\ That fantasy lasted about two sprints.

I Was Trained to Believe Specs Were Sacred

Back when I started out as a BA, we were taught to treat documentation like gospel.

\ You wrote it all down—every scenario, exception, flow, dropdown option, tooltip. The longer the spec, the more “complete” it was. If it made it to 20 pages? Even better.

\ I once spent three weeks writing a spec for a search filter. No one questioned it. That was just the norm.

Then Agile Happened—And My Confidence Cracked

Agile hit like a cold shower.

\ Suddenly we were in sprint planning talking about “just enough” documentation. Stories were short. Acceptance criteria were lean. My 20-page documents became the elephant in the room no one had time to read.

\ The first few sprints? Painful.

\ Dev asked me things that werealready in the spec.

\ QA missed stuff because they were waiting for a walkthrough I didn’t have time to give.

\ And I kept thinking:“Why is no one reading this?”

\ The truth? They didn’t need to.

\ What they needed wasme, in the room, talking with them—not hiding behind a Google Doc.

My Wake-Up Call Came in a Retro

I’ll never forget this.

\ In a retro, one of the devs (very kindly) said:

\

“We appreciate the effort, but the spec is too much. We’d rather walk through the story with you and get clarity directly.”

\ That one line shifted everything for me.

\ I realized I wasn’t writing specs for them—I was writing them for me. To feel prepared. To feel useful. To prove I was doing my job.

\ But in an Agile world, usefulness doesn’t come from a polished doc. It comes from creating shared understanding.

I Burned the Spec—and Found Something Better

After that retro, I tried something radical.

\ I replaced a full-blown spec with:

  • Three user stories
  • A sketchy whiteboard diagram
  • One 30-min conversation with the team

\ That was it.

\ It felt risky. Like showing up underdressed to a formal party.

\ But the team got it. They asked questions. They suggested ideas. QA chimed in with edge cases I hadn’t thought of.

\ And the feature shipped—faster, better, and with less friction than ever before.

What I Use Now (Instead of Specs)

🧩 User Story Mapping— For seeing the flow, not just the features \n 🧠Personas— To anchor decisions in user goals \n ✅Lean acceptance criteria— So “done” is clear, but not rigid \n 🎤Team conversations — Because no spec beats a 15-min talk

\ And sometimes… \n

I still write things down. But not as a crutch. As a compass.

The Hard Truth: Specs Made Me Feel in Control. But They Weren’t Saving Me.

Specs gave me the illusion of safety.

\ I thought they would shield me from mistakes, misunderstandings, and scope changes. But all they really did was delay reality.

\ What works now is different:

  • I talk more. I listen harder.
  • I stay involved through delivery, not just at kickoff.
  • I let go of perfect. I aim for progress.

Final Thoughts: You Don’t Need a Spec. You Need a Seat at the Table.

If you’re a BA struggling to let go of “the way it used to be,” I get it. I was you.

\ But Agile doesn’t need scribes. It needs connectors.

\ People who create alignment, not attachments.

\ People who know how to lead in a room full of change.

\ So write if you must. But don’t hide behind it.

\ Be the reason the team builds the right thing.
