The Practice

A Clearer Picture of What the Numbers Mean

Quantum Lattice works with leadership teams who face decisions too consequential to leave to instinct alone. We bring quantitative rigour and structured analysis to the problems that keep you up at night.

Quantum Lattice started in a rented desk at a co-working space in Edinburgh's New Town in January 2017. Dr. Marcus Hale had left Meridian Capital Partners the previous autumn with a single conviction: that the gap between what organisations know and what they decide was not a data problem. It was a method problem. The first client was a mid-sized infrastructure fund that had been sitting on eighteen months of project performance data and could not agree internally on what it meant. The engagement took nine weeks. By the end of it, the fund had a working model, a documented decision framework, and, perhaps more usefully, a shared vocabulary for disagreeing productively.

The practice grew slowly and deliberately. In 2019, Quantum Lattice moved to a permanent office and brought on a second analyst, Priya Nair, who had come from the Government Statistical Service and brought with her a discipline around data provenance that has shaped every engagement since. That same year, a referral from the infrastructure fund led to a relationship with a regional NHS trust that was trying to model patient flow across three sites. The work was harder than anything done before, partly because the data was messier and partly because the stakes were more visible. It took longer than planned. The model that came out of it is still in use.

Strategic Decision Analysis

Strategic Decision Analysis

From £8,500

A six-to-ten-week engagement built around a single high-stakes decision. We begin with a structured problem-framing session, then build a bespoke quantitative model in Python or R, run scenario and sensitivity analysis, and deliver a written report with full supporting documentation. The final session is a working meeting with your leadership team, not a slide presentation.

Quantitative Risk Model

Quantitative Risk Model

From £6,000

We build a probabilistic risk model calibrated to your data, your sector, and your specific risk horizon. The model produces ranges rather than point estimates, with explicit documentation of every assumption. Delivered with annotated code and a handover session. We have built these for infrastructure funds, NHS trusts, and professional services partnerships.

Data Audit and Diagnostic

Data Audit and Diagnostic

From £3,200

Four weeks. We review your existing data infrastructure, interview the people who maintain it, and produce a prioritised roadmap identifying gaps, inconsistencies, and quick wins. The output is a written report and a working session. Useful before a larger engagement or as a standalone exercise when something feels off but you cannot locate the source.

Organisational Forecast Model

Organisational Forecast Model

From £4,800

A rolling forecast model for revenue, headcount, or operational capacity, built to be maintained by your team after handover. Includes full documentation, annotated code, and a half-day training session. We have built these in Excel, Python, and R depending on what your team is most likely to actually use.

Why Problem Framing Matters More Than the Model

There is a version of quantitative consulting that begins with the data. You receive a file, you build a model, you deliver a report. It is a coherent service. It is also, in our experience, frequently the wrong one. The most consequential work we do at Quantum Lattice happens before a single number is touched, in the sessions where we try to establish what question is actually being asked.

Probabilistic Forecasting: Why Ranges Beat Single Numbers

Every forecast is, at its core, a probability distribution. The question is whether you show the distribution or collapse it into a single number before presenting it. Most organisations choose the single number, for understandable reasons: it is easier to communicate, easier to hold someone accountable to, and easier to put in a slide. It is also, in most cases, a less honest representation of what the analysis actually shows.

When to Commission a Data Audit (and What to Expect)

The most common trigger for a data audit is a specific incident: a report that produced a number nobody believed, a model that gave contradictory outputs on different days, a board question that nobody could answer with confidence. These incidents are useful. They create the organisational will to look carefully at something that is easy to defer. But they are rarely the root cause. They are symptoms.

How We Work

Structured Problem Framing

Before any analysis begins, we spend time mapping the actual decision at stake. Most engagements reveal, within the first week, that the stated problem and the real problem are not the same thing.

Quantitative Modelling

We build bespoke models in Python and R, calibrated to your data and your risk tolerance. No off-the-shelf dashboards. Every model is documented so your team can interrogate it independently.

Scenario and Sensitivity Analysis

We stress-test every recommendation against a range of plausible futures, including the ones your team finds uncomfortable to discuss. The goal is a decision that holds up, not one that looks good in a slide.

Implementation Support

We stay involved through the first phase of execution. Recommendations that sit in a report and gather dust are a failure of the engagement, not a success.
