For product and engineering teams

Argue the design before you build it.

The expensive mistakes ship months before anyone sees them, in the decisions. Wavn is where the design argument happens on the record, while changing course is still cheap.

Every engineering organization already knows the truth Wavn is built on: the costly failures were decided, not coded. The architecture chosen for the team you had, the feature cut that removed the point, the migration timed by optimism. Teams that write design docs know the cure is the argued, recorded decision; they also know the doc goes stale the day it merges. Wavn keeps the argument alive: locked calls with kept dissent, revisits that fire when assumptions expire, and the trade-off history the next engineer actually needs.

The decisions you live with

Where the cost of getting it wrong is real.

The architecture you live with

Chosen in a fortnight, lived with for five years. The strongest case against deserves a named advocate.

The feature you cut

Scope cuts are strategy decisions at code speed. The reasoning should outlive the sprint board.

The migration you time

Too early burns the roadmap, too late burns the team. The bet deserves an argument and a revisit.

The debt you accept on purpose

Deliberate debt is fine; undocumented debt is a trap for whoever comes next. Lock it with its reason.

How Wavn fits the work

Your workflow, with the thinking kept.

The voices

The design review that always happens

No calendar tetris. The Believer, the Skeptic and the Operator take the design at full strength on demand.

Lock

ADRs that write themselves

The call, the context and the consequences, locked in the shape architecture decision records always wanted to be.

Revisit

Assumptions with expiry dates

The build-versus-buy call returns when the vendor changes pricing, with the old reasoning on screen.

The record

Why the system is the way it is

The new engineer reads the decisions, not the tribal memory of whoever is left.

Built

The spec and the comparison, finished

Design docs, vendor comparisons and migration plans as real files, ready for the review.

One call, walked

Said, argued, decided, built. Then it comes back.

The difference

No single voice is trusted alone.

In your field, confident and wrong is expensive. Wavn shows the case for, the case against, and what nobody raised. Then the call is yours, on the record.

Illustrative scenario

A platform team

A platform team · Build versus buy · Auth system

A platform team must decide whether to keep building its own auth or move to a vendor. Half the team has scars from each direction, and the debate has eaten three planning sessions.

  1. The question is put once, properly. The voices argue it: control and cost against speed and surface.
  2. The converge map separates fact from preference: two agreed, one contested, one honestly open.
  3. Buy locks, scoped, with the exit strategy named in the decision and the build case kept as dissent.
  4. The vendor comparison and migration plan land as finished files. A revisit is set against the vendor’s next pricing change.
The outcome: Eighteen months later the vendor triples its price. The revisit fires with the original exit strategy on screen, and what would have been a crisis is a Tuesday.
This scenario is illustrative, a composite of how teams in this field work, not a named client.

Wavn will not design your system. What it does is make sure the design was argued by its strongest opponents before the first line was written, and that the why survives the team.
