Re:Invent Work for the Asynchronous Era
Execution is already fast.
Decisions are what is slow.
AI made the doing of work parallel. Organizations still are not faster, because decision-making stayed synchronous — meetings, waiting for replies, approvals, confirmations. UTSUROI is infrastructure for lowering that synchronous share so decisions can scale.
01 — Amdahl's law
Your ceiling is set by the synchronous share.
No matter how much execution you parallelize, total performance is governed by the part that cannot be parallelized — Amdahl's law. In an organization that part is the synchronous region: meetings, waiting for replies, approvals that live in one person's head, confirmations. Now that execution is effectively free, this is the only thing setting your speed.
Maximum organizational performance ≒ 1 / synchronous share
UTSUROI aims to take that share from 40% down to 1%. Not working faster — building a structure that scales correctly.
02 — The bottleneck
"Stuck" comes from not being able to see.
Decisions pile up unmade not because people are lazy, but because the state of the work is invisible.
- Nobody knows whose ball it is right now.
- Nobody knows whether it is awaiting review or not started.
- No deadline was ever set.
- A decision is stalled inside someone's head.
UTSUROI extracts the state of work from everyday communication and task movement, and gives it structure. Not structure for the sake of oversight — structure that detects a stall and gets the work moving again.
03 — Built into the flow
Remove the drops instead of blaming them.
A flow that depends on human memory and attention accumulates a small error at every step. Turn the request itself into the task — swap that one mechanism and the odds change by an order of magnitude.
The usual flow
- A makes a request5% B never reads it
- B copies it into a task tracker5% never entered · 15% no due date
- B checks their tasks10% missed
- B does the workIt falls through before it gets here
The UTSUROI flow
- A makes a request — it becomes a task0% unread
- The copying step disappears0% never entered · 0% no due date
- The due date is announced in the open1% missed
- B does the workWork arrives without stalling
Stop treating a dropped request as an individual failing and make it something the process detects and handles. Because the mechanism catches them, a team can move to asynchronous work without anxiety.
04 — The screens
The state shows up on two screens.
The work that gets picked up comes back in two views: a Kanban board for whose ball it is right now, and a Timeline for when it lands. The same tasks, asked two different questions.
05 — Product
Work as usual; the machinery runs underneath.
UTSUROI asks nothing special of you. Chat as you always do, move tasks as you always do, and underneath it structures the work, estimates it, reconciles it and makes it visible.
From chat straight to tasks
The Slack integration spots requests and neglected threads in everyday conversation and structures them into tasks that carry an owner and a due date.

Velocity is a record, not a target. Estimates grounded in what actually happened give you a timeline you can defend.
Learn more →Bottlenecks made visible
Which task, whose decision, how long. "We are stuck" becomes data rather than a feeling.
Learn more →MCP and AI integration
Let AI draft project timelines and break down tasks. With MCP support you can drive UTSUROI straight from the AI tools you already use.
Learn more →Skills — your team's know-how
Register the way your team works as a Skill. Similar past tasks, estimates and outcomes accumulate and become reusable by other teams.
It reaches everywhere
Slack is only the first doorway. With public webhooks, UTSUROI connects to email, GitHub and whatever else you run on.
06 — Design principles
Assume people are imperfect.
People take time off.
People prioritize something else.
— and the work keeps flowing anyway.
We do not rely on the fantasy that everyone follows every notification and never misses a mention. Task management that does not depend on notifications. Accountability that does not depend on anyone's memory. Miss a mention, skim past Slack, and your task list still tells you everything you owe. That is the state UTSUROI is built for.
End the era of managing people.
In a world of AI and portfolio careers, organizations need a structural change to release the potential they already have. UTSUROI is the infrastructure for shifting into that new shape.
UTSUROI — 移ろい. To keep changing without ever stagnating.
