The Performance Function owns the diagnostic architecture.
The client relationship, scope, evidence standards, project structure, synthesis, and quality expectations remain with the firm. Specialists may change by project; the standard does not.
About the firm

The Performance Function helps organizations nationwide examine recurring performance problems, understand the conditions behind them, and choose changes they can measure.
Founder · The Performance Function
Matthew Hilley
M.Ed., BCBA
Matthew’s background in behavior analysis and education informs The Performance Function’s approach to organizational performance: examine the conditions surrounding the work before recommending a change.
When delays, rework, or inconsistent execution keep returning, the diagnostic looks at how work is assigned, where handoffs break down, and what information people need to do the job. Findings are tied to observable outcomes so leaders can decide what to change and check whether it helped.
Matthew holds a Master of Education and is a Board Certified Behavior Analyst. Each consulting engagement is matched to the expertise the problem requires.
How the model works 01 · Firm-owned standard 02 · Specialist matching 03 · Quality review
One standard. Project-specific expertise. Independent challenge.
Expertise is matched to the actual problem.
No credential alone qualifies someone for an engagement. Matching considers the problem, industry context, comparable experience, measurement and data competence, client-facing capability, jurisdiction, security requirements, and any relevant licensing or professional restrictions.
Final work is designed to be challenged before it reaches the client.
Independent quality review tests evidentiary support, causal overreach, ignored alternatives, metric connection, scope, competence, and drift into advice outside the engagement’s professional boundaries.
Built to grow carefully
Capability sets the scope of our work.
We would rather decline work than stretch expertise beyond what the engagement requires.
Every project must have the appropriate specialist competence, methodology, insurance, legal authority, and quality-control standards behind it. Our capabilities can expand, but only when the infrastructure to support the work expands with them.
If those conditions are not in place, we do not sell the work.
What we value 01 02 03
Clear claims. Bounded scope. Useful work.
Precision
Say what the evidence supports, not what sounds strongest in a presentation.
Practicality
Recommendations should be implementable in the client’s real operating environment.
Accountability
Connect proposed changes to a metric and a way to verify whether they worked.
Start with the problem you can see.
You do not need to know the cause before reaching out. That is the point of the diagnostic.
