How can we help?
Employee retention & turnover
Retention Management Consulting
Harbinger helps executives and HR understand unwanted turnover, identify critical employee groups and measurably improve retention. Workforce metrics, interviews and leadership practice inform a retention strategy that can be implemented and managed in everyday work.
For executives, HR directors and People leaderswho want to understand where commitment is being lost before funding further initiatives.
Experience & trust
Retention strategy takes shape where data meets everyday work
Harbinger works at the intersection of executive leadership, HR, workforce metrics, people management and operational reality. This is where retention is determined: in the data, employees’ daily experiences and the organisation’s ability to translate those insights into effective action.
Harbinger’s retention expertise
Data capability meets leadership expertise
Our analysis goes beyond turnover rates. We connect reasons for leaving, focus groups, leadership, culture and business impact to create a basis for decisions by management and HR.
“Employee retention is a central driver of value and deserves to be managed accordingly.”
— Tim Grove, CEO, Harbinger AG
When turnover becomes a business risk
Turnover costs more than the recruitment budget
When experienced employees leave, the loss extends beyond headcount. Knowledge, customer relationships and stability leave with them, while pressure on recruitment and managers rises. Current figures for Germany illustrate the scale of untapped retention potential.

Where commitment is lost
Unwanted turnover usually follows recognisable patterns
The decisive step is to understand which factors drive resignations in your organisation, and for which employee groups.
Limited development
A lack of opportunities to learn, take responsibility or progress weakens loyalty, particularly among ambitious specialists and high-potential employees.
Weak leadership
Managers can be a reason to stay or leave. Appreciation, clarity and development are experienced through everyday leadership.
Cultural distance
When values, purpose and daily experience do not align, employees often begin to disengage long before they resign.
Pay & recognition
Pay matters. Risks grow when performance, recognition and decisions are perceived as unfair or opaque.
Overload & instability
Persistent stress, uncertainty and a lack of structure increase intentions to leave and undermine commitment and trust.
Why isolated initiatives rarely suffice
Retention management with clear priorities
A benefit can be useful and still miss the underlying problem. Harbinger first distinguishes symptoms, triggers and structural causes and then translates the findings into a prioritised retention strategy.
Analysis & differentiation
We combine turnover data, interviews and employee surveys into a reliable assessment, identifying the causes and groups that need attention first.
Retention Management
The result is a prioritised retention strategy. Leadership, culture, development, pay and work organisation are addressed where they can influence outcomes.
Our principle: Different groups need different responses. We differentiate where data and working realities reveal meaningful differences, such as location, function, tenure, career stage or a critical role.
Making retention manageable
Retention becomes manageable when employee groups and KPIs align
We combine workforce metrics with qualitative findings from interviews, surveys and focus groups to provide an evidence-based view of commitment.
KPI 1
Retention Rate
What proportion of employees stay during the defined period, overall and within business-critical groups?
KPI 2
Turnover rate
Where is voluntary or involuntary turnover increasing, and which areas differ from internal or external benchmarks?
KPI 3
Engagement index
How strong are motivation and emotional commitment, and where are early signs of disengagement emerging?
KPI 4
Additional indicators
Sickness absence, tenure, new-hire retention, internal mobility and productivity measures provide further context.

Harbinger prioritises by: Retention risk × business criticality × scope for influence. Priority goes to issues that matter to the business and can realistically be changed, rather than automatically to the largest group.
What makes people stay
Lasting commitment develops on three levels
An individual benefit rarely resolves a structural retention problem. We consider financial, emotional and cultural factors together and prioritise the strongest opportunities for impact.
Rational commitment
Financial incentives
Fair pay, bonuses and benefits form a foundation. They become effective when pay is transparent, recognises contributions and fits the strategy.
Emotional commitment
Appreciation, development & trust
Feedback, development opportunities, participation and good leadership create commitment that competitors cannot easily outbid.
Cultural commitment
Identification & purpose
Purpose, lived values and belonging influence whether employees are proud of their employer and want to stay for the long term.

How your organisation benefits
Retention management improves cost, stability and capability
Business value comes from fewer unwanted departures, more stable teams and better decisions about the factors that make people stay.
Cost
Reduce recruitment and replacement pressure
Fewer critical departures reduce recurring costs for search, selection, onboarding and vacancies.
Stability
Retain knowledge and team performance
Experience, customer relationships and established collaboration stay in the organisation instead of having to be rebuilt repeatedly.
Management control
Target investment in HR initiatives
Understand where retention risks are greatest, which groups matter and which actions have an impact.
From causes to measurable impact
How a retention project with Harbinger works
The approach is modular. We can start with a focused analysis or support the full process through implementation and measurement.
4 phases · from causes to impact
Phase 1Situation & causes
Baseline analysis & focus groups
We bring together KPIs, reasons for leaving, surveys, interviews and benchmarks to reveal critical groups and hotspots.
OutcomePrioritised risk groups and evidence-based hypotheses about causes.
→Phase 2Goals & actions
Strategy & design
Analysis informs clear goals, action areas, work packages, responsibilities and a realistic timeline.
OutcomeA retention strategy tailored to employee groups, with clear priorities.
→Phase 3Pilot & integration
Implement retention actions
We pilot actions, involve managers, prepare communication and then scale successful approaches.
OutcomeActions implemented in practice.
→Phase 4Measurement & adjustment
Monitoring & evaluation
Retention, turnover, engagement and other indicators are reviewed regularly and actions adjusted accordingly.
OutcomeCommitment becomes visible, manageable and measurable.
Tailored to your organisation: Scope, data, priority groups and project duration reflect your needs. A clearly defined area can serve as a pilot before scaling.
Leadership as a retention lever
Leadership determines whether commitment develops in everyday work
HR cannot manage retention alone. Managers shape appreciation, development, communication, workload and team cohesion, all central reasons for staying or leaving.
Relationships & appreciation
Regular feedback, listening and fair decisions create trust and emotional commitment.
Development & opportunity
Managers make career and learning opportunities tangible, helping high performers see a future within the organisation.
Direction & stability
Clear communication, sound priorities and healthy leadership reduce uncertainty and strengthen cohesion.
Harbinger’s approach: Leadership is treated as a strategic lever where the analysis demonstrates that it can influence retention.
When consulting adds value
When external retention advice is useful
Typical starting points
- Turnover remains high despite benefits and training.
- The actual reasons for departures remain unclear.
- KPIs, surveys and focus groups fail to produce a shared picture.
- HR lacks the capacity or methods for a structured programme.
- An objective external view of leadership or culture is needed.
What Harbinger brings
- An objective assessment in place of internal assumptions.
- Benchmarks and clear priorities for management and HR.
- Actions that fit your employee groups and organisation.
- Support from initial assessment through implementation.
- Measurement and ongoing adjustment.
Before the project
What decision-makers should know about retention consulting
Most initial questions can be clarified early. The key is to define the problem, employee groups and decisions clearly; perfect data is not a prerequisite.
When is external retention management consulting useful?
External support is useful when turnover rises in particular functions, locations or employee groups and internal explanations differ. It also helps when benefits, training and surveys already exist but clear priorities are missing. Harbinger combines data, conversations and the business importance of affected roles into a shared assessment, enabling a sound decision about where to start and what can wait.
What data do we need to get started?
A first assessment does not require a perfect HR data landscape. Headcount, joiners, leavers, tenure and meaningful function or location groupings are usually sufficient. Reliable exit reasons, survey results, absence and internal mobility add context. Missing or inconsistent data becomes part of the diagnosis. Together, we determine the level of detail the decision actually needs.
How does Harbinger distinguish symptoms from causes?
A stated reason for leaving is often the final trigger. A better offer may accelerate a decision, while limited development, sustained overload or poor leadership created the willingness to leave earlier. We examine triggers, experienced reasons and structural causes separately. Quantitative patterns show where problems occur; interviews and focus groups help explain why.
How are employee groups and actions prioritised?
We assess potential priority groups by retention risk, business criticality and scope for influence before selecting actions. An easy-to-introduce benefit has little value if it does not address the actual driver of departures. Structural issues do not always require an immediate company-wide response; a clearly defined pilot is often a better starting point.
Who should be involved internally?
An effective project needs a clear sponsor and accountable project lead. Depending on the question, HR or People & Culture, HR Analytics or Controlling, and managers from affected areas should be involved. The works council and data protection specialists should participate early when surveys or personal data are involved. Analysis, decisions and implementation must remain connected.
How long does a project take, and how is success measured?
Scope and duration depend on how clearly the issue is defined, available data and whether Harbinger supports analysis alone or also piloting and implementation. A focused area can serve as a pilot. We agree scope, outputs, responsibilities and review frequency before starting. Measures go beyond overall turnover: depending on the group, they include voluntary departures, new-hire retention, internal mobility, engagement and qualitative leadership and team signals. Early indicators show changes in behaviour and work experience; outcome metrics later reveal whether retention is more stable.
Clarity before action
First, we identify where commitment is being lost
In an initial conversation with no obligation, we assess which departures are business-critical, which groups need attention and what data is available. This establishes whether a focused analysis or broader retention project is appropriate.
