What changed in the business, and what it did to the outlook.
Not an event feed and not a notification centre. Each signal says what happened, what it changed versus the previous forecast, how certain the figure is, and whether anyone needs to act. Routine activity stays out of the way.

2 material changes

Impact, confidence, urgency
Ordered by what matters, not by when it happened.
Sebastian scores every change on financial impact, confidence in the calculation and decision urgency. A $200K cost increase with metered evidence outranks a $300K one that rests on a guess. Thresholds are yours, by account and by amount.
- Impact is measured against the previous forecast, not against plan alone
- Confidence comes from the evidence: metered, signed, posted, or inferred
- Urgency reflects whether a decision window is closing
A signal tells you what happened. Work tells you what needs doing.
Most changes update the outlook and stop there. When a change crosses a policy threshold or needs a judgement, Sebastian creates the right piece of work, assigns it, and links it back to the signal so the two never drift apart.
- The hiring delay updated the outlook and created nothing
- The contract amendment created a revenue treatment review for Daniel
- The cloud increase opened an investigation shared by finance and engineering

What stops happening
Finding out at the close
A signed amendment, a usage spike or a slipped start date reaches finance the day it happens, with its financial effect already calculated.
Reading every alert
Fourteen routine changes this week were folded into the outlook without raising anything. Four were worth your time.
Trusting a number without knowing how firm it is
Every signal carries its confidence and the evidence behind it. Low confidence is shown as a question, not hidden in a total.
Knowing what changed, before and after Sebastian

| Noise | Alerts from every connected tool, each with its own idea of important. | Material changes raised, routine changes folded into the outlook and listed. |
| Follow-through | An email thread that may or may not end in a decision. | A piece of work with an owner, a due date and a link back to the signal. |
