HR operating model / role clarity
Ulrich HR Model (Four Roles)
Dave Ulrich's model organizes HR's work into four roles along two axes: strategic versus operational focus, and process versus people.
It is the default lens for diagnosing what an HR function actually spends its time on, and what it neglects.

Theory & origin
David Ulrich introduced the four-role model in Human Resource Champions (1997) to answer a question boards kept asking: what is HR actually for? He argued HR creates value along two tensions: a focus that runs from day-to-day operations to long-term strategy, and an orientation that runs from process to people. A healthy function delivers on all four roles instead of defaulting to administration. Later revisions folded these roles into the shared-services, business-partner and center-of-expertise operating model most large organizations run today.

How a consultant runs it
- 01 Pull activity or time-allocation data and map where HR effort actually lands across the four roles. Most functions cluster heavily in Administrative Expert.
- 02 Run a target-mix workshop with leadership: given the business context, what should the four-role balance be in 18 months?
- 03 Quantify the shift you want (for example, move 25 points of capacity from admin to strategic partner) and name the concrete activities that move.
- 04 Turn it into an operating-model design: what gets automated, outsourced or centralized to free up the capacity.
- 05 Set two or three role-mix metrics and revisit them quarterly, so the shift is actually managed, not just aspirational.
When to use
- 01 Diagnosing an HR function's current role mix versus its desired one, in HR transformation projects
- 02 Structuring an HR operating model or HR org design conversation
- 03 Explaining to non-HR executives what "strategic HR" concretely means
When not to use
- 01 As a literal org chart. The roles are lenses, not departments.
- 02 For assessing individual HR practitioners. Use a competency model instead.
- 03 When the client needs process-level detail. The model is deliberately high-altitude.
Worked example
A 2,000-person manufacturer complains that HR is "too administrative." Mapping activity data onto the four roles shows 70% of HR time going to Administrative Expert, 20% to Employee Champion, and under 10% combined to Strategic Partner and Change Agent. The transformation case: automate or outsource admin work to shift 30 points of capacity toward the strategic roles, with named activities for each one.
Common pitfalls
- 01 Treating all four roles as equally weighted for every company. The right mix depends on business context.
- 02 Declaring "we are all strategic partners now" while nobody owns admin excellence. The operational roles are load-bearing.
- 03 Using the 1997 model without acknowledging Ulrich's later revisions, like shared services, HRBPs, and the center-of-expertise operating model
