Strategically Planning and Quality-Assured Management of External Staffing Needs

Manage staffing needs rather than reacting at the last minute

Peak workloads, unplanned absences, multiple assignment locations, and tight onboarding timelines increase the need for coordination. If requirements are not clarified until shortly before an assignment begins, this leads to delays, mismatched profiles, and the need for additional replacements.

Reliable planning brings together business units, HR, recruiting, operations, and procurement early on. It documents tasks, qualifications, assignment conditions, and responsibilities. This allows you to allocate resources according to need and manage assignments in a transparent manner.

Accurately Assessing Demand

The number of people needed alone is not sufficient for planning. Other critical factors include the nature of the assignment, the expected duration, required skills, locations, working hours, and the time needed for onboarding.

Distinguish between short-term peaks, regularly fluctuating demand, and long-term capacity building.

Additional orders or seasonal fluctuations often require short-term staffing planning. Long-term needs, on the other hand, require a realistic assessment of the labor market, internal recruiting capacities, and desired employment prospects.

For each need, document at least the following points:

• Occasion and time frame: Scope and planned duration of the assignment

• Requirements profile: Tasks as well as mandatory and desirable requirements

• Assignment conditions: Assignment location, working hours, shift schedule, and start date

• Capacity planning: Available internal resources and expected bottlenecks

• Responsibilities: Responsibilities for onboarding, training, and approvals

• Quality criteria: Readiness for the assignment, professional suitability, and feedback

This common framework facilitates approvals and makes changes visible early on.

Deriving Staffing Models from Needs

The appropriate staffing model is determined by the duration, predictability, and qualifications required for the specific need. Also take internal resources and employment prospects into account.

Temporary Staffing for Limited-Term Capacity Needs

Temporary work or staffing services can be used for temporary or fluctuating needs, provided that applicable regulations are met.

Before deployment, review the tasks, duration, work location, working hours, and qualifications. If there are multiple locations, you’ll need separate information regarding training, access regulations, and responsibilities.

Staffing for Long-Term Needs

Staffing may be appropriate for long-term or specialized needs. The decision depends, among other things, on the availability of suitable specialists, the qualification profile, and the internal effort required for selection.

Define early on which steps will be handled internally and where external support makes sense. This ensures the recruiting process remains predictable and the selection process transparent.

RPO for Predictable Recruiting Capacities

Recruitment Process Outsourcing (RPO) involves external support or the outsourcing of agreed-upon recruiting steps. These may include sourcing, pre-screening, scheduling, and reporting.

RPO can relieve the burden on internal teams when recruiting capacities fluctuate. This requires clearly documented requirements, defined interfaces, and a regulated flow of information.

Data-Driven Recruiting for Transparent Decisions

Data-driven recruiting supports decision-making when requirements, processing statuses, and feedback are consistently recorded. A digital workflow can consolidate information and clarify responsibilities.

The data does not replace professional judgment. It helps you identify discrepancies in profiles, approvals, or start dates early on.

Organize compliance and deployment preparation in a binding manner

External staffing requires clear responsibilities, complete documentation, and regulated occupational safety measures.

Before the assignment begins, determine who will review requests for personnel, grant approvals, organize training, and document feedback from the business unit.

Plan for location-specific requirements early on. These include, in particular:

• Access regulations and internal approval processes

• Safety measures and occupational safety

• Work schedules and shift models

• Workplace-specific training

• Documentation Requirements and Responsibilities

Changes to tasks, work locations, or scheduling models must be communicated to the relevant departments.

Measuring Time and Quality Consistently

Clear definitions are essential for robust management. In particular, companies should distinguish between three time-related metrics:

• Time-to-Fill: Typically describes the period from when a position is approved until an offer is accepted.

• Time-to-Hire: Begins when a person enters the recruiting process and also ends with the acceptance of an offer.

• Time to Start of Assignment: Measures the period from the agreed-upon start date to the actual start at the assignment location.

For external staffing, the time until the start of the assignment is particularly relevant. It differs from time-to-fill and time-to-hire because approvals, training, and assignment conditions can also influence the start date.

Define the following measurement criteria for each metric:

• Measurement period: Start and end dates of the measurement

• Time unit: Calendar days or workdays

• Data basis: Data source and responsible department

• Special cases: Handling profile changes, interruptions, and withdrawals

• Evaluation: Differentiation by location, qualification profile, or assignment model

Comparisons are only meaningful if the calculation remains consistent. Therefore, document exceptions, such as delayed approvals or changed assignment conditions.

Derive Staffing Quality from Underlying Causes

Staffing quality is not determined by speed alone. It encompasses professional suitability, availability for the agreed-upon date, retention in the assignment, and feedback from the department.

Use a few, clearly defined metrics to evaluate the quality of external staffing assignments in a transparent manner:

• Staffing rate at the start of the assignment: Shows whether the planned staffing needs are met by the agreed-upon date.

• Retention in the assignment: Assesses whether an assignment continues beyond a specified period.

• Replacements: Indicate which assignments require additional staff.

• Time to assignment start: Illustrates the process from the request for staff to the actual start of the assignment.

Assign each metric to a clear reference variable. People, assignments, and work hours address different questions and should therefore not be mixed together.

Examine Causes Rather Than Just Results

Always evaluate reassignments and absences on a case-by-case basis. Possible causes include:

• changed work schedules or assignment conditions

• vaguely defined tasks and requirements

• missing information prior to the start of the assignment

• incomplete onboarding and training

Only the combination of metrics and feedback reveals what adjustments are necessary.

Implement improvements systematically

A structured improvement process begins with demand planning. Agree on requirements, success criteria, responsibilities, and a reporting schedule before the assignment begins.

When the business unit, HR, recruiting, and operations evaluate the results together, concrete measures can be defined. These include, for example:

• more precise job descriptions

• early planning of training sessions

• adjustments to capacity planning

• clearer coordination between the departments involved

Designate a responsible party and a deadline for feedback for each measure.

When expanding to additional locations, you should re-evaluate local requirements. Working hours, occupational safety, training, and documentation requirements may vary depending on the assignment location.

Conclusion: Manage external staffing needs in a predictable and quality-assured manner

Strategic workforce planning means managing external capacity based on clear requirements and measurable criteria. Documented tasks, qualifications, working conditions, and responsibilities form the basis for reliable decisions.

Classify temporary staffing, recruitment, or RPO based on specific needs. Consider national regulations in Germany and Austria separately.

Consistent metrics and regular feedback help you identify root causes and refine processes in a targeted manner.
