In every HR transformation journey, the design phase serves as the foundation that determines long-term success or sets the stage for future complications. One of the most critical, yet frequently overlooked, decisions during this phase is selecting the right employment model: Should your organization implement a Single-Assignment or Multiple-Assignment Structure?
While this may appear to be a minor technical detail, its impact resonates throughout the entire HR landscape. Choosing the wrong model can result in significant rework, user experience challenges after go-live, and scalability issues particularly in multi-phase implementations.
The Role of Implementation Partners
Customers often don’t have full visibility into the downstream impacts of design decisions. Thus, it is critical for implementation partners and system integrators (SIs) to take on the role of trusted advisors. Their responsibility is to lead HR teams toward well-informed, future-ready decisions and not just functional configurations.
Industry Matters: Why One Size Doesn’t Fit All
Certain sectors such as Education, Healthcare, and Public Services inherently demand a multiple-assignment employment model. Here’s why:
- Educational Institutions frequently employ staff who juggle teaching, research, and administrative roles, each requiring distinct compensation and scheduling.
- Healthcare Organizations rely on flexible staffing where professionals often serve across departments, units, or specialties each with different pay structures and costing methods.
For such industries, a one-dimensional model simply doesn’t suffice. Yet, even in organizations with less apparent complexity, considering downstream implications can reveal the need for multi-assignment flexibility.
Key Factors to Guide Your Employment Model Decision
When deciding on the most suitable employment model, it’s important to consider a range of strategic questions.
- Does your workforce often hold multiple roles across departments, and is there a need for concurrent job schedules, varying shifts, or differentiated compensation structures?
- Are your payroll systems equipped to handle assignment-level costing, unique pay structures such as hourly versus salaried, or budget allocations tied to specific roles?
- Do leave entitlements, working hours, or approval processes differ between assignments? Are there licensing requirements or compliance rules—such as union agreements or location-based legal obligations—that vary by job type?
- From an employee experience perspective, can individuals easily manage multiple roles through self-service tools, and is the onboarding and performance management process streamlined or fragmented?
- Looking ahead, will the chosen model scale effectively as you adopt additional modules like Time & Labor, Payroll, or Talent? Finally, what level of administrative overhead will this model place on your HR, Payroll, and IT teams, and do you have the internal capability to manage this complexity?
Why This Decision Matters More Than You Think
Choosing an employment model is not just about today’s HR needs—it’s about setting a resilient foundation for tomorrow’s challenges. Organizations that fail to consider downstream integrations with Payroll, Finance, Compliance, and Talent often find themselves facing expensive system redesigns later.
That’s why implementation partners must engage stakeholders from across the business early in the process. By guiding informed, strategic choices, they don’t just configure systems—they enable long-term transformation and agility.
