Every assumption has an owner, a source and a reason.
A capital result is only as defensible as the assumptions behind it: loss ratios, premium volumes, reinsurance terms, dependency parameters. In most firms those assumptions live in workbooks, and their history lives in someone’s inbox. STEER records each one as a governed entry, so “why is that 62%?” has an answer on screen.
One row per assumption: current value, owner, source, effective date and rationale. Every change creates a new version. Nothing is overwritten.
A proposed change is visible before it is accepted. STEER records who proposed it, who challenged it and who approved it, with the reasoning kept alongside.
See the direction and rough size of a change before it is committed to a full run. The preview stays clearly labelled as indicative until the model confirms it.
Fast when you’re exploring. Rigorous when you’re deciding.
The board asks “what if we grow Cyber by £50m?” Today, the honest answer is “we’ll come back to you next cycle”. STEER gives two answers, and never lets them be confused.
Request a run in one click. STEER records who asked, for which scenario and on which model version. It then tracks the run honestly (requested, running, passed or failed) rather than pretending a long calculation is instant.
Every result carries its evidence: reconciliation checks, convergence and sensitivity diagnostics, the random seed and digital fingerprints of the exact inputs and code used. Any run can be reproduced to the penny.
A run requested at 4pm on a Thursday is held to the same standard as the year-end run. Fast never means informal.
Candidate plans side by side, with the argument attached.
Pick a baseline and a candidate, and STEER lines them up on capital, return and appetite. Every movement is tied to two specific, identified model runs, so you can see exactly where the capital moved: by class, by risk type and by risk driver.
STEER explains movements as well as showing them. When growth in one class adds less capital than expected, the comparison shows why: extra reinsurance recoveries, a shift in diversification, or both.
SCR, diversification benefit, expected result, solvency ratio and return on capital for each candidate plan. Comparisons across different risk measures, units or simulation settings are flagged, not quietly netted off.
The case for each scenario is written where the numbers are, not in a separate memo that drifts out of date.
The comparison becomes the paper the board reads, with every figure linked back to the run that produced it.
A decision becomes a record, not a recollection.
When management lands on a choice, STEER records it as a Decision: the recommendation, the rationale, the owner and the approval. Each Decision is linked to the exact scenario and the exact model run that supported it.
One click from a decision to its scenario, its model run and the data underneath.
Approval is a named action, open only to authorised approvers. It is available only once the supporting run has passed its checks and been reviewed.
Change an approved scenario and STEER creates a new version. The old one is marked superseded, and fresh model evidence is required before the new one can be approved.
STEER sits above the calculation layer. The model your actuaries built and validated stays exactly where it is, and remains the only place capital is calculated.
