Operating decisions
We focus on repeated choices that affect margin, cash, capacity, service or growth.
Fable builds software for expensive recurring decisions
We work on choices where the facts sit in several systems, the outcome is uncertain and the organisation controls a specific action.
We start with the decision itself.
For a Decision Engine, we define the operator's choice, reconstruct the evidence available at that moment and model the outcomes that could change the answer.
Operating Systems compose several engines to run a whole function, such as a deal desk, a project commercial team or an underwriting desk.
Traceable software
Source records, models, constraints and value calculations remain linked from forecast to outcome.
Stewardship
After deployment, we monitor the evidence, models, policy, operator use and results.
The team on every engagement.
The same Fable team works with you from the first assessment through to life after go-live.

- AnalystsWork out how the decision is made today, what it costs and, with your finance team, how value will be measured.
- Data engineersConnect your source systems, map the data and keep the combined record reconciled.
- Data scientistsBuild, test and calibrate the models against the agreed baseline.
- Machine learning engineersRun approved models in production, with version control, monitoring and a rules-based fallback.
- Deployment engineerInstalls the engine in your environment, sets up access and approvals, and runs go-live.
- SecurityLooks after access, secrets and deployment controls, and works with your team through security and procurement review.
- StewardshipWatches data, models and outcomes after go-live, and reports results to your finance team.
