Finding 01

The vertical familiarity premium is larger than expected.

Across every firm and engagement type in the dataset, consultants with two or more prior engagements in the client's specific industry vertical outperformed their peers on composite outcome scores by an average of 38%. The effect was consistent across firm size, engagement duration, and project type.

The finding holds even after controlling for seniority level. A junior consultant with strong vertical familiarity outperforms a senior generalist in 61% of comparable engagement configurations.

Finding 02

At-risk signals appear 4 weeks before clients say anything.

The study tracked 387 engagements that resulted in client escalation calls. In 91% of cases, at least one leading signal was present in behavioral data at least 28 days before the escalation. The most reliable signals were billing cadence deviation and client-side meeting attendance patterns.

Of firms surveyed, 78% reported that they were not systematically monitoring these signals at the time — not because they were unaware of their predictive value, but because the data was too dispersed to read in aggregate.

Finding 03

Decision confidence is measurably higher when historical data is present.

Partners and practice leads who had access to historical engagement pattern data before making staffing decisions rated their confidence in fit at 3.2× higher than those making decisions from memory and availability alone. The effect was strongest for staffing decisions involving consultants the practice lead had not personally supervised in a similar engagement.

This finding suggests that the value of pattern data is not primarily in providing new information, but in systematizing information that exists but isn't accessible in the moment the decision is being made.

Methodology note

This report draws on engagement and staffing data from a sample of mid-market consulting firms (30–500 consultants) analyzed with client consent between January 2024 and December 2024. Firm and consultant identities are anonymized. Outcome scores are composite metrics derived from billing completion, client renewal rates, and internal engagement assessment. The sample includes 2,400 engagements across 14 industry verticals.

Findings are descriptive, not prescriptive. They describe patterns present in this dataset; individual firm results will vary based on engagement type, client mix, and organizational context.
