You’ve probably been in that sprint planning meeting where someone confidently declares, “We don’t need a full spec, we’ll just figure it out as we go.” Six sprints later, you’re drowning in technical debt, the team is burned out, and the product looks like a Frankenstein monster stitched together from half-baked ideas.
We’ve been sold a lie. Somewhere along the line, the tech industry convinced itself that agility meant abandoning specification. We traded clear requirements for sticky notes and called it progress.
Agility without specification isn’t iteration; it’s just organized chaos with a faster burn rate.
The usual fallacious argument is that agile equals no spec. But agility never asked us to stop writing specs. It asked us to shorten the feedback loop. It showed us a path to work in an iterative fashion to reveal misunderstandings and inadequacies earlier—not after six months of blind execution.
Think about it. How can you iterate on something if nobody knows what the baseline is? How can you give meaningful feedback on a feature if the definition of “done” changes every Tuesday based on who yelled the loudest in Slack?
Specification isn’t a cage to trap developers; it’s the shared language that makes agility actually work.
When you write a spec, you aren’t trying to predict the future. You’re trying to force the hard conversations to happen before you write a single line of code. You’re exposing the vague requirements, the hidden edge cases, and the conflicting stakeholder demands.
If you’ve ever been burned by vague requirements or endless, directionless iterations, it’s time to reframe the debate. The real failure of modern agile adoptions isn’t too much structure—it’s too little. We’ve been cargo-culting the rituals of agility while ignoring the disciplined foundation required to pull it off.
Writing a spec is an act of empathy for your future self and your teammates.
It’s time to reject the fake agility that creates chaos under the guise of flexibility. Embrace the rigid structure of specification, and watch how fast your team can actually move when everyone finally understands what they’re building.
FAQ
Q: Doesn't writing specs just slow down development?
A: No, it speeds it up. Writing a spec prevents you from building the wrong thing for three sprints straight. A few hours of alignment saves weeks of rework.
Q: How much specification is actually enough?
A: Enough to align the team on the 'what' and the 'why' before debating the 'how.' You don't need a 50-page document, just a clear, shared understanding of the current iteration's goals.
Q: Isn't this just a sneaky way to bring back Waterfall?
A: Not at all. Waterfall tries to predict the entire final state upfront. Agile specs define the immediate iteration with full intent to adapt based on what you learn.
