Make-or-Buy in Recruiting: Which HR Processes Should Stay In-House –
and Where External Partners Add Value
Recruiting has become significantly more demanding for many companies. Labor markets are tighter, candidates are more selective, departments expect faster hiring and internal HR teams are often already operating at full capacity.
This turns the question “Should recruiting stay in-house or be outsourced?” into a strategic make-or-buy decision. Companies need to understand which recruiting and HR processes they should control internally – and where external staffing partners can provide faster, more scalable and more cost-effective support.
The key point: Outsourcing recruiting does not mean giving up control. It means keeping strategic responsibilities in-house while assigning operational, time-consuming or fluctuating tasks to external experts.
What Does Make-or-Buy Mean in Recruiting?
Make-or-buy in recruiting means that companies consciously decide which recruiting tasks they handle internally and which they assign to external partners. This may include active sourcing, applicant management, candidate pre-screening, permanent placement, temporary staffing, flexible workforce models or entire recruiting processes.
The goal is not to outsource as much as possible. The goal is to create an economically sensible division of responsibilities. The company keeps control over strategy, culture and final hiring decisions. External partners support areas where speed, reach, market knowledge or scalability are decisive.
Why Make-or-Buy in Recruiting Is Becoming More Important
Many HR departments are still responsible for traditional core tasks such as contract management, payroll, HR administration, employee data and employment law topics. At the same time, they are expected to recruit more actively, strengthen employer branding, approach candidates directly and advise departments strategically.
In daily operations, this often creates bottlenecks. Vacancies remain open longer, managers spend more time on recruiting, operational teams come under pressure and selection processes become inconsistent.
This is especially relevant for mid-sized companies, industrial businesses, logistics providers, production sites, administrative teams and customer service organizations. They increasingly need to ask: Which recruiting tasks do we really need to manage ourselves – and which can external staffing partners handle more efficiently?
Outsourcing Recruiting Without Losing Control
A common concern is that companies lose influence over hiring decisions when they involve external partners.
This does not have to be the case. Successful recruiting outsourcing clearly separates strategic control from operational relief.
Companies should continue to define which profiles they need, which requirements are essential, what kind of culture candidates need to fit into and who is ultimately hired.
External staffing partners can support tasks that are especially time-consuming or require specific market access: candidate acquisition, direct search, applicant management, pre-screening, administration or flexible staffing models.
This keeps decision-making authority inside the company while reducing workload for HR teams and departments.
Which Recruiting Processes Should Stay In-House?
Not every HR task is suitable for outsourcing. Some areas are closely linked to strategy, culture and leadership and should therefore remain under internal control.
Strategic Workforce Planning
The question of which skills a company will need in the next 12, 24 or 36 months is a strategic leadership responsibility. It depends on growth plans, digitalization, production planning, location strategy and market development.
External partners can provide market insights, salary indications and candidate availability data. However, the decision about which roles will be business-critical in the future must remain internal.
Employer Branding and Employer Positioning
A company can receive support with communication, campaigns and candidate messaging. But its true employer identity cannot be fully outsourced.
What makes the company attractive as an employer? Which values are genuinely lived? Which promises can credibly be made to candidates? These answers must come from within the organization.
Final Hiring Decision
The final hiring decision should always remain with the company. Only internal managers and teams can fully assess whether a person is the right professional, cultural and organizational fit.
External partners can identify, approach and pre-screen suitable candidates. The final decision remains internal.
Onboarding and Employee Retention
Even if an external partner supports the search process, integrating new employees remains an internal responsibility. Onboarding, leadership, team integration and long-term retention cannot be fully delegated.
Where External Staffing Partners Provide Measurable Relief
External support is especially valuable when recruiting tasks are operationally demanding, time-critical or difficult to scale.
Candidate Acquisition and Active Sourcing
Actively approaching suitable candidates requires time, experience, tools and networks. For many companies, it is not economically sensible to build dedicated sourcing structures for every occupational group.
Especially for skilled trades, shift workers, logistics roles, commercial specialists and technical functions, external staffing partners can often provide faster access to suitable candidates.
Pre-Screening and Applicant Management
A large part of recruiting effort happens before the final interview: reviewing applications, contacting candidates, checking availability, completing documents, matching requirements and coordinating appointments.
These tasks require a lot of time but are not always strategic. External partners can reduce workload by presenting only suitable and pre-qualified profiles.
Short-Term or Fluctuating Staffing Needs
Internal HR teams are usually designed for an average hiring demand. Bottlenecks occur when many positions need to be filled at the same time and at short notice.
Typical triggers include new orders, seasonal peaks, production ramp-ups, site expansions, project launches or sickness-related absences. External staffing partners can add speed and flexibility in these situations.
Temporary Staffing and Flexible Workforce Models
Temporary staffing, employee leasing and project-based staffing models involve administrative and legal requirements. These include workforce planning, contract documentation, deadlines, equal-pay regulations, working time issues and compliance.
Experienced staffing partners have established processes and routines to implement flexible staffing models efficiently and in line with legal requirements.
Specialized Search in Tight Labor Markets
Some profiles are difficult to reach through traditional job ads. This applies, for example, to maintenance, quality management, production, logistics, technical professions or technical sales roles.
In these cases, simply publishing a job ad is often not enough. Direct approach, market knowledge and existing candidate pools are needed.
Common Mistakes in Make-or-Buy Recruiting Decisions
Many companies only consider external support once pressure is already high. This often creates avoidable costs.
One common mistake is comparing only direct costs. External provider fees are visible, while internal effort is often underestimated. But internal recruiting also consumes time from HR, managers and departments.
Vacancy costs must also be considered: production delays, overtime, postponed projects, lower service quality or additional pressure on existing teams.
Another mistake is trying to fill all roles with the same recruiting model. Production workers, commercial profiles, specialists, technical experts and executives differ significantly in search channels, availability and selection processes.
A sound make-or-buy decision therefore considers role type, urgency, hiring volume, qualification level, labor market availability and internal capacity.
When Is It Worth Outsourcing Recruiting?
Recruiting outsourcing or external staffing support can be particularly useful when several of the following points apply:
Vacancies regularly remain open for more than six weeks.
The HR team is permanently working at capacity.
Managers spend a lot of time on recruiting tasks.
Traditional job ads do not generate enough suitable applications.
Several roles need to be filled at short notice.
Staffing needs fluctuate due to orders, projects or seasonality.
Certain profiles are difficult to find in the regional market.
Time-to-hire affects production, service, projects or delivery capability.
Flexible staffing models create legal or administrative uncertainty.
Hiring quality is inconsistent or early turnover is too high.
The more points apply, the more likely it is that external recruiting support will be economically worthwhile.
Which External Recruiting Models Are Available?
Permanent Placement
Permanent placement is suitable when companies are looking for direct hires but lack internal sourcing capacity or face a difficult candidate market. The staffing partner identifies suitable candidates, checks their fit and supports the process. The employment contract is concluded directly between the candidate and the company.
Temporary Staffing
Temporary staffing is useful for short-term, seasonal or fluctuating staffing needs. Companies gain flexibility without immediately entering into long-term employment commitments. This model is particularly relevant in production, logistics, warehousing, industry and service areas.
Recruitment Process Outsourcing
Recruitment Process Outsourcing, or RPO, is suitable for companies with high hiring volumes or standardized recruiting processes. An external partner takes over defined parts of recruiting or the entire process.
Managed Services and Process Outsourcing
Managed services go beyond filling individual positions. They support operational sub-processes or entire functional areas, for example in warehousing, assembly, quality checks, administration or workforce management.
How Companies Can Make a Sound Make-or-Buy Decision
A strong decision is based on transparency rather than gut feeling.
First, companies should map which recruiting tasks are currently handled internally and how much time they actually require. Next, staffing needs should be structured: Which roles are needed regularly? Where do short-term peaks occur? Which profiles are particularly difficult to find?
After that, costs should be compared realistically. This includes internal working time, opportunity costs, vacancy costs, job advertising costs, tool costs and potential provider fees.
A practical starting point is often a pilot project – for example for one occupational group, one location or one clearly defined staffing need. Useful KPIs include time-to-fill, candidate quality, process workload, cost per hire and department satisfaction.
Conclusion: More Efficient Recruiting Without Giving Up Control
Make-or-buy in recruiting is rarely an either-or decision. The best solution is often a hybrid model: companies keep strategy, culture and final hiring decisions in-house while assigning operational, time-consuming or fluctuating tasks to external partners.
This keeps control within the company while reducing workload for HR teams and departments.
We support companies in assessing staffing needs, choosing suitable recruiting models and making HR processes more efficient – from permanent placement and temporary staffing to comprehensive process support.

Total Cost of Vacancy
What unfilled roles really cost – and how companies can take action
Unfilled roles are more than just an organisational problem. They have a direct impact on productivity, turnover and team dynamics – often more so than is immediately apparent. Nevertheless, the actual costs of unfilled roles are underestimated in many companies.
The so-called Total Cost of Vacancy (TCV) reveals precisely these hidden effects. Understanding it enables you to make more informed recruitment decisions – and take targeted action.
What does Total Cost of Vacancy mean?
The Total Cost of Vacancy describes the total costs incurred by a vacant position – ranging from direct financial losses to indirect effects within the company.
These include, amongst others:
lost revenue or delayed projects
productivity losses within the team
additional workload for existing staff
opportunity costs due to missed market opportunities
additional costs due to prolonged recruitment processes
The longer a position remains unfilled, the more these factors add up.
Why vacant positions are often more expensive than expected
Many companies focus primarily on the costs of a new hire – such as salary, recruitment expenses or onboarding. The costs of a vacant position, on the other hand, are often not systematically recorded.
Yet they can quickly turn out to be significantly higher.
Example:
If a sales-related position remains unfilled, not only is there a lack of operational capacity – potential revenue is also lost. In project-based areas, delays can lead to contractual penalties or follow-up orders that cannot be fulfilled.
Internal costs also arise: teams have to take on extra tasks, shift priorities or work overtime. In the long term, this can affect motivation and performance.
How to calculate the Total Cost of Vacancy
An exact calculation is not always straightforward, but an approximation already provides a valuable basis for decision-making.
Typical calculation methods are:
Revenue-based calculation: Annual revenue per employee ÷ working days = potential daily loss
Productivity-based approach: Proportion of work not performed within the team × average value added
Project-based assessment: Costs arising from delays, lost contracts or inefficient use of resources
What matters is not so much the exact figure as the understanding:
Every day a position remains unfilled has a measurable economic impact.
Where the greatest time losses occur in recruitment
To reduce the Total Cost of Vacancy, it is worth examining typical factors causing delays in recruitment:
unclear or overly complex job profiles
lengthy coordination processes between departments
lack of prioritisation of open positions
limited internal recruitment capacity
lack of access to suitable candidates
Especially when combined, these factors lead to recruitment processes dragging on unnecessarily.
How companies can specifically reduce their time-to-fill
Anyone wishing to reduce the costs of unfilled positions must focus primarily on the time-to-hire. Several levers can help with this:
1. Consistently simplify recruitment processes
Clear responsibilities, fewer coordination loops and structured decision-making processes speed up the entire process – without compromising quality.
2. Make sensible use of technology
Digital solutions can make recruitment processes significantly more efficient – for example, through automated matching, structured data processing or optimised communication.
Modern HR technology solutions help to identify candidates more quickly and speed up administrative processes.
3. Secure access to qualified talent pools
Time is often wasted by having to start each search from scratch. Access to existing networks or qualified candidate pools can significantly shorten this process.
A structured recruitment process helps to identify suitable candidates more quickly and streamline the selection process.
4. Utilise flexible staffing models
Not every vacancy needs to be filled immediately on a long-term basis. Flexible models can help bridge short-term bottlenecks, particularly for time-critical needs.
Temporary staffing, for example, makes it possible to deploy qualified staff quickly whilst gaining time to make a sustainable hiring decision.
A strategic shift in perspective: recruitment as a value driver
The Total Cost of Vacancy clearly shows that recruitment is not merely a cost factor, but a crucial lever for business success.
Companies that optimise their recruitment processes benefit in several ways:
lower financial losses due to vacancy periods
more stable team structures
faster implementation of projects
better utilisation of market opportunities
A fast and efficient recruitment process therefore has a direct impact on competitiveness.
Conclusion: Every vacant role comes at a price
Unfilled positions often incur higher costs than initially assumed. The Total Cost of Vacancy highlights these impacts – and lays the foundation for better recruitment decisions.
Companies that accelerate their processes, access the right resources and respond flexibly can significantly reduce these costs whilst ensuring their ability to act.

Between dedication and burnout
How much flexibility does the modern job really require?
Flexible hours, remote work, self-managed teams, and flat hierarchies: Today’s modern job market promises one thing above all else—freedom. Terms like “New Work,” “agility,” and “personal responsibility” represent work models designed to adapt to life, rather than the other way around.
For many employees, however, this new freedom feels ambivalent. What begins as self-directed work often tips over into constant availability, mounting pressure, and the feeling of having to constantly do more in everyday life. The central question is therefore: How much flexibility makes sense—and at what point does it become overwhelming?
Flexibility needs clear boundaries
Originally, flexibility was intended as a mutual compromise. Companies gain committed employees who work independently and take on responsibility. Employees, in turn, gain more leeway in shaping their lives—for example, regarding working hours or location.
This model becomes problematic when flexibility is tacitly equated with unlimited availability. When meetings regularly take place outside of traditional working hours, messages are expected even in the evenings or on weekends, or the workday in the home office no longer has a clear end, the boundaries between work and private life increasingly blur. Flexibility then loses its positive character and becomes a burden.
A modern job therefore requires not only freedom but, above all, binding framework conditions. Without clear agreements, uncertainty arises—and responsibility shifts unilaterally onto employees.
New Work means responsibility—but not having to bear everything alone
Self-organization and personal responsibility are central elements of modern work models. They can be motivating because they open up creative freedom and signal trust. At the same time, however, they require a high degree of direction, prioritization, and decision-making ability.
Many employees feel internal pressure to handle everything on their own. Support is rarely sought because it does not seem explicitly provided for. Yet even in the context of New Work, personal responsibility does not replace leadership or communication. Employees need clear goals, feedback, and points of contact—especially when hierarchies are deliberately reduced.
When commitment gradually turns into overload
Overwhelm usually doesn’t arise suddenly but develops gradually. Additional tasks are taken on, breaks are shortened, and recovery time is postponed. The motivation to “do a good job” often reinforces this process. Especially in flexible work models, it’s difficult to draw clear boundaries—particularly when performance is measured by results rather than working hours.
In the long run, this leads to the loss of precisely what modern work concepts are actually meant to promote: concentration, creativity, and sustainable performance. Those who consistently push beyond their limits risk burnout and emotional detachment—even from a job they originally started with great enthusiasm.
Setting boundaries is professional—not inflexible
Many employees still worry that setting clear boundaries will make them appear unable to handle stress or uncommitted. Yet the opposite is true. Boundaries show that someone realistically assesses what is achievable, takes responsibility for their own health, and wants to work reliably in the long term.
This can mean communicating fixed availability times, openly discussing the scope of work, or pointing out high workloads early on. Such conversations are not a sign of weakness, but an expression of professionalism—especially in work environments that place a strong emphasis on personal responsibility.
Clarify expectations early on—ideally during the application process
How flexible a company really is usually only becomes apparent in day-to-day work. Nevertheless, many aspects can already be addressed during the job interview. Questions about work schedules, availability policies, or how the company handles workloads help paint a realistic picture.
An employer who takes flexibility seriously will answer these questions transparently and clearly. After all, sustainable performance doesn’t come from constant availability, but from clarity, trust, and realistic expectations on both sides.
Conclusion: True flexibility requires structure
Modern jobs undoubtedly require adaptability, initiative, and dedication. But flexibility is only a step forward if it is clearly defined and based on reciprocity. Without structure, it quickly becomes overwhelming.
New Work does not mean always being available. It means working mindfully, taking responsibility—while knowing and respecting one’s own limits.

Pay Transparency Directive 2026:
Why Salary Ranges Will Decide Recruiting Success
An uncomfortable truth: Lack of transparency costs time, money and trust
Many companies initially view the Pay Transparency Directive 2026 as a compliance issue.
Another regulation. Another obligation.
In reality, it exposes a structural weakness in many organisations: pay is often decided historically, individually or situationally – not systematically.
The consequences are well known:
long approval loops between HR, line management and executive leadership
candidates withdrawing late in the process due to salary issues
internal pay discrepancies that are hard to explain
From 2026 onwards, this approach will no longer be inefficient only – it becomes risky.
What the Pay Transparency Directive actually changes
The EU Pay Transparency Directive requires companies to make compensation decisions explainable and structured, starting with recruiting.
The three core requirements:
1. Salary ranges in job ads or before interviews
Employers must inform candidates early about:
a specific starting salary or
a realistic salary range for the role
Vague wording such as “competitive salary” or excessively wide ranges do not meet the intention of the regulation.
2. No questions about salary history
Asking candidates about their previous salary will be prohibited.
Compensation must be based on role, responsibility and market value – not negotiation history.
3. Explainability internally and externally
Companies must be able to explain:
why a role sits within a certain salary range
why comparable positions are paid differently
The burden of proof in pay‑gap disputes will increasingly shift to employers.
Why pay transparency is a business issue – not an HR project
For Managing Directors and Production Managers, the key insight is this:
Pay transparency directly impacts operational performance, not just employer branding.
Typical effects of unclear pay structures:
delayed hiring for critical roles
overtime, production delays and productivity losses
higher fluctuation due to internal pay inequity
Transparency forces decisions before job postings go live – and that is exactly what accelerates recruiting.
The biggest misconception: “This means higher salaries”
Pay transparency does not automatically increase personnel costs.
It increases decision discipline.
Prepared organisations experience:
fewer renegotiations
fewer exceptions
fewer salary outliers
The leverage is not budget – it is structure.
A pragmatic model for defining salary ranges
1. Job families instead of individual positions
Group similar roles into job families, such as:
Production
Maintenance
Logistics
Administration
Define 2–4 levels per family. This dramatically reduces special cases.
2. Limit to three objective pay drivers
Proven criteria include:
scope of responsibility (equipment, budget, teams)
required qualifications / skill scarcity
market or location factors
More criteria increase complexity and reduce consistency.
3. Clearly defined exception rules
Exceptions should exist – but be defined, not negotiated:
When can the upper end of a range be used?
When explicitly not?
This prevents internal inequity and uncontrolled salary inflation.
4. Integrate pay ranges into the recruiting process
Pay ranges only work if they are:
fixed during HR–line manager briefings
actively communicated in first candidate conversations
the foundation of the offer – not its outcome
Practical example: Shift‑based manufacturing company
A manufacturing company urgently needs maintenance electricians.
Previously: individual negotiations, long approvals, candidate dropouts.
After implementing transparent salary bands:
HR communicates ranges and shift premiums upfront
line managers assess skills and availability only
offers are made faster – and accepted more often
Not because salaries increased – but because decisions became clear.
The right KPIs to measure transparency and speed
Transparency should be measured operationally, not emotionally:
drop‑out rate due to salary
offer acceptance rate
time‑to‑offer
share of band‑compliant offers
ratio of new hires to internal salaries in similar roles
These KPIs quickly show whether transparency creates impact – or only communication.
Conclusion: 2026 will separate structured from reactive employers
The Pay Transparency Directive is coming — regardless of opinion.
The real question is how companies respond.
Those treating salary transparency as a checkbox risk friction and uncertainty.
Those using it to clarify decisions and standardise processes gain:
faster hiring
higher offer acceptance
lower legal risk
stronger trust on both sides of the labour market
Pay transparency is not a loss of control.
It is a gain in manageability.
If you would like to address these questions in a structured and pragmatic way, we would be happy to talk.
We support companies in designing clear, market‑based recruiting and compensation frameworks.

Leading Without a Management Role
How to Make Your Impact Count Even Without a Title
Not all leadership is reflected in the organizational chart. In the modern workplace, many people take on responsibility without officially holding a leadership position. They coordinate projects, drive initiatives forward, mediate between interests, or provide technical guidance. This often happens quietly—and remains invisible precisely because of that.
Yet leading without a title is more important today than ever before. Specialists and project team members play a key role in shaping companies, even without disciplinary authority. What matters is not the position, but the impact. Those who understand how leadership works beyond formal power can make themselves visible, build trust, and strategically strengthen their own professional development.
Leadership begins with attitude, not hierarchy
Many still associate leadership with the authority to give instructions, decision-making power, or personnel responsibility. In the practice of modern organizations, however, leadership has long been defined more broadly. It manifests itself where people provide direction, take on responsibility, and inspire others.
This starts with one’s own attitude. Those who lead without being managers act proactively, think beyond their own scope of work, and take responsibility for the overall outcome. This inner clarity is the foundation of credibility. Colleagues follow not because they have to, but because they trust.
Visibility comes from reliability and contribution
Many high-performing professionals make an important contribution but remain in the background. Visibility is often mistakenly equated with loudness. In reality, it arises from reliable results, clear communication, and tangible added value for the team.
Those who take responsibility, tackle problems in a structured way, and offer solutions get noticed—regardless of their title. What matters is not just working through tasks, but recognizing connections and actively shaping them. Leadership without a title means not passing on responsibility, but accepting it.
Influence comes from relationships, not from instructions
Without formal power, leadership requires one thing above all else: relational competence. People do not let themselves be led; they choose to follow. Listening, understanding perspectives, and weighing interests are central elements of informal leadership.
This form of influence is particularly evident in project work. Deadlines, priorities, and conflicting goals can rarely be imposed—they must be negotiated. Those who communicate clearly, respectfully, and in a solution-oriented manner are perceived as a unifying force. This builds trust and establishes one’s position at the same time.
Technical expertise translates into leadership influence
For experts in particular, their own professional expertise is a major lever. Those who make complex topics understandable, provide guidance, and share knowledge automatically assume a leadership role. This is not about knowing everything better, but about contextualizing issues and preparing the ground for decisions.
It is important not to withhold expertise, but to contribute it in a targeted manner. Visible leadership here means taking responsibility for quality, standards, and further development—in a fact-based and constructive manner.
Show initiative—without being pushy
A common balancing act for high potentials is to show initiative without appearing dominant or overbearing. Leadership without a title does not mean taking everything upon oneself, but rather providing impetus. Those who make suggestions, point out alternatives, or take on a moderating role actively contribute to shaping the process without overstepping formal roles.
It is precisely this ability to offer responsibility rather than demand it that is highly valued in modern work environments. It signals maturity, self-reflection, and leadership ability.
Strategically shaping perceptions
Becoming visible also means consciously communicating one’s own role. Many professionals accomplish a great deal but speak little about it. Leadership without a title therefore also means contextualizing successes, making progress transparent, and clearly defining areas of responsibility—objectively, not in a self-promoting manner.
It is crucial to place one’s own contribution within the context of the team or project. Those who demonstrate how their work contributes to the larger goal are perceived as a driving force.
Conclusion: Leadership is demonstrated through action
Leadership responsibility does not begin with a title and does not end with personnel responsibility. It manifests itself in everyday life, in interactions with others, in the willingness to take on responsibility, and in providing guidance.
For specialists, high potentials, and project team members, this form of leadership offers a great opportunity: it makes development visible, strengthens one’s own position, and paves the way for the next career step—without any formal authority.
