Management work is often described by function, but execution happens at the boundaries between functions. This report examines which functional interfaces employers explicitly name when they describe collaboration in a frozen sample of 100 US management vacancies from eight employers in the 2026 Fortune 100.

The report is a point-in-time descriptive snapshot. It is not a census of the Fortune 100, a ranking of employers, an estimate of the US management labour market or evidence that an unmentioned interface is absent from a role.

Research question

When a management vacancy in the frozen corpus uses an explicit collaboration cue, which named functional families appear in the same sentence, and how often do vacancies name two or more families?

Scope and sample

The evidence base contains 100 unique public vacancies captured in August 2026 from Amazon, Apple, Alphabet (Google), UnitedHealth Group, McKesson, Microsoft, JPMorgan Chase and CVS Health. These employers were selected from the 2026 Fortune 100. The set was frozen before this analysis and no vacancy was added or removed after results were known.

The sample is purposive. Employer counts range from five to 18, and titles, functions and capture conditions are not evenly distributed. Results describe this corpus only.

Method

We normalized each vacancy body and split it into sentences. A collaboration sentence contained at least one bounded cue such as “partner with,” “collaborate with,” “work closely with,” “coordinate with,” “liaise with,” “interface with,” “cross-functional” or “stakeholders across.” Equal-opportunity and reasonable-accommodation boilerplate was excluded.

Twelve named function families were coded only when a family term appeared in the same sentence as the collaboration cue: Finance; Legal; People/HR; Sales; Marketing; Product; Operations/Supply; Technology/Engineering; Data/Analytics; Risk/Compliance/Audit; Procurement/Contracts; and Customer/Service.

One vacancy could receive multiple function codes. Counts therefore do not sum to 100. The coding is a conservative text rule, not a model of organizational structure. We retained source URL, capture date, code list and a bounded evidence excerpt for review.

Main findings

Eighty-four vacancies contained at least one non-boilerplate collaboration cue. Sixty-seven named at least one of the 12 functional families in the same sentence. Forty-eight named two or more families.

Measure Vacancies Share of sample
At least one collaboration cue 84 84%
At least one named function beside a cue 67 67%
Two or more named functions beside cues 48 48%

The 33 vacancies with no named family are not evidence of isolated work. Some used generic terms such as “stakeholders” or “cross-functional teams”; others may describe interfaces elsewhere without the selected cues.

Functions named at collaboration points

Functional family Vacancies Share of sample
Technology / Engineering 37 37%
Operations / Supply 21 21%
Risk / Compliance / Audit 19 19%
Finance 13 13%
Legal 11 11%
Sales 11 11%
Product 11 11%
Customer / Service 9 9%
Marketing 8 8%
Data / Analytics 8 8%
Procurement / Contracts 5 5%
People / HR 2 2%

Technology/Engineering was the most frequently named family in the sample. That result partly reflects the employer and title mix, including technology companies and technical management roles. It should not be generalized to all management vacancies.

Repeated co-occurrences

When two named families appeared in the same collaboration sentence, the most common pairs were Product with Technology/Engineering (11 vacancies), Operations/Supply with Technology/Engineering (nine), Operations/Supply with Risk/Compliance/Audit (seven), Data/Analytics with Technology/Engineering (six), and Risk/Compliance/Audit with Technology/Engineering (six).

These are text co-occurrences, not validated reporting lines. They identify interfaces worth testing in a role conversation or portfolio exercise.

Employer-level variation

The share with at least one named interface ranged from zero of five CVS Health vacancies to 11 of 12 McKesson vacancies. Small and unequal employer samples make cross-employer comparison unstable. The variation also reflects different page formats, role mixes and writing styles.

Practical application: build an INTERFACE-5 portfolio

Students and managers can translate the findings into five pieces of evidence:

  1. Boundary map: name the two functions, shared decision and handoff point.
  2. Common definition: define the unit that both sides use, such as qualified opportunity, accepted risk or release readiness.
  3. Evidence record: show the source, owner, timestamp and uncertainty behind the decision.
  4. Exception route: state who decides when measures conflict or evidence is incomplete.
  5. Review result: document what changed after the cross-functional review.

For example, a Product-Technology interface portfolio might contain a release-readiness definition, dependency register, test evidence, exception decision and post-release review. A Finance-Legal interface might contain an approved commercial assumption, contract condition, accounting implication, escalation and signed decision record.

Do not manufacture employer-confidential evidence. Use a fictional case, public information or sanitized work that you are authorized to share.

Limitations

  • The purposive sample covers eight Fortune 100 employers, not all 100 companies.
  • Vacancy counts are unequal across employers and functions.
  • Public postings may omit real interfaces or use terms outside the coding dictionary.
  • Sentence boundaries are imperfect in web-extracted text.
  • Co-occurrence does not establish ownership, importance or causality.
  • The August 2026 snapshot should not be treated as a current-vacancy count after the capture period.

Reproducibility and integrity

The archival package contains the report PDF and a supporting workbook with the 100 coded observations, function counts, employer summaries, pair counts, method and source URLs. Raw vacancy text is not redistributed; the workbook preserves bounded evidence excerpts and public links to reduce rights and privacy risk. AI is not an author or evidence source.
