The answer
HSflow™
A standardised, GDPR-neutral instrument that addresses all four requirements with a single measurement. GDPR architecture verified: Prinz Legal Consulting (May 2026).
Data protection & anonymity

Individual responses remain invisible. Even to us.

Each swipe is immediately converted into a score and discarded. The specific responses of any individual are technically irrecoverable. Only the aggregated group-level result is stored. Finally a tool that works councils can support in good conscience. Nothing is stored that could be attributed to a person. Since § 87 (1) no. 6 BetrVG is triggered by the processing of personal data, no co-determination requirement arises in this respect.

No processing of personal data within the meaning of the GDPR — reviewed and confirmed by legal counsel (Prinz Legal Consulting, May 2026, in relation to the GDPR under German law). The works-constitution conclusion is one we draw from the reviewed facts; it is not itself the subject of the legal opinion.

Regulatory Framework

HSflow addresses CSRD/ESRS S1 and EmpCo across the EU. The applicable local regulations depend on your country of incorporation. For companies with German subsidiaries: §5 ArbSchG covers the psychosocial part of the workplace risk assessment, §1 StaRUG covers psychosocial risks in the crisis early warning system. GDPR-neutrality confirmed by Prinz Legal Consulting (May 2026) for the German legal framework. Since § 87 (1) no. 6 BetrVG is triggered by the processing of personal data, no co-determination requirement arises in this respect — a conclusion we draw from the reviewed facts, not part of the legal opinion itself. The legal classification in other countries is the responsibility of the respective company.

Early warning system

Nerves and money saved.
Ahead through early detection.

Conventional approaches kick in when the problem is already visible. HSflow detects the imbalance two steps earlier, before it becomes a symptom. While others treat symptoms, you are already working with the facts.

Conventional approach
?
Root cause invisible
The underlying imbalance goes undetected. Nobody knows what is really wrong.
?
No early detection
No metrics, no warning signals. The system drifts, invisibly, for weeks.
!
This is where work begins
Symptoms become visible: conflicts, chaos, absenteeism rising. Only now is action taken.
€€
Damage — too late
Sickness rate up. Turnover increased. The damage has already been done.

vs
With HSflow™
✓
Root cause identified
The dashboard shows immediately: where is the imbalance? Missing stability, elevated risk level. Precise and documented.
⚑
Early detection
KPIs show warning signals before symptoms emerge, two steps earlier than conventional approaches.
→
Symptoms understood
When symptoms become visible, the cause is already known. Targeted intervention instead of guessing.
✓
Damage reduced or prevented
Intervention at the root prevents an imbalance from becoming a costly problem — or significantly reduces the damage.
two steps ahead

“While others are guessing at symptoms, with HSflow you see the root cause, two steps earlier.”

The decisive budget argument

A good gut feeling
instead of gut feeling.

Every organisation invests in training, coaching, culture programmes. Until now, effectiveness was gut feeling. HSflow makes it measurable, with the Measure Effect Score (MES) and ColorFlow Balance. Make decisions based on data and see in black and white what the measure achieved.

Before the measure
Targeted instead of broad
Because the cause is known, the intervention, training, coaching, restructuring, hits exactly the right problem. No scattering, no hoping.
Same budget, triple impact, because it is deployed in the right place
→
After the measure
Did it work?
The MES shows in black and white: has the system state changed? For the first time, effectiveness is no longer gut feeling but a number. Did the money make a difference?
Documented, reproducible, methodically transparent
◎
This applies at both levels: for the entire workforce (CSRD/Own Workforce) and for individual managers or teams. For the first time, people development is no longer a matter of faith.
System diagnostics

Always on the right track,
because you know the cause.

HSflow is not a survey tool, but a system diagnostic instrument. Here is an example: Same symptom. Different cause. Different solution.

Observation identical in both cases
“The team does not dare to make decisions.”
Diagnosis A: what HSflow shows
Psychological safety
Critically low
Stability level (HSS)
Critically low
What the system shows
The team is experiencing genuine fear. Making a mistake feels threatening. This is a safety problem, not a competence problem.
Right intervention
Build psychological safety: error culture, trust, leadership behaviour. Not: decision-making training.
≠
Diagnosis B: what HSflow shows
Control & structure drive
Extremely overloaded
Adaptability (TCI)
Strongly reduced
What the system shows
The system is frozen in perfectionism. Decisions fail because there is never enough data. This is a structural problem.
Right intervention
Activate decision courage: legitimise 80% solutions, strengthen execution culture. Not: even more analysis.
✕ Without HSflow
Both receive the same “decision-making workshop”. By chance it helps A, but has no effect on B. Budget wasted, problem remains.
✓ With HSflow
System diagnosis in 48 hours reveals the cause. Targeted intervention. The MES then shows: it worked.
Causal chains

Intervention at the root,
not at the branch.

From confirming the observation to the right intervention. HSflow shows the complete chain.

◎
It is often only small nuances in the system state that determine whether a measure truly takes effect or fizzles out. HSflow makes exactly these nuances visible.
Example · The burnout path
HSflow shows the complete chain
What is observed
Withdrawal, avoidance, passivity. The team becomes invisibly quiet.
↓
What the KPIs show
Psychosocial risk rises into the critical zone. Warning level active before anyone falls sick.
↓
System state · the root
Psychological safety is absent. Mistakes feel threatening.
↓
Right intervention
Do not demand courage. First create the ground on which courage can grow.
Business impact without intervention
Sickness rate rises. Turnover increases. +€400,000 in follow-on costs p.a. for 100 employees.
With targeted intervention
Stability score rises. Sickness rate falls. The MES shows: the measure worked.
Workforce assessment

No more fumbling in the dark
in any department.
Not even the night shift.

Other systems survey managers or take samples. The HSflow Workforce Assessment truly reaches everyone, without questionnaires, without IT effort, without additional translation costs. For finally more response rates, even from areas like the shop floor.

Swipe instead of filling in forms
No long questionnaire. Intuitive swiping, immediately understandable even for people without office experience. Shop-floor ready from day 1.

Multipliers inside the organisation

Two roles decide
whether it starts at all.

An instrument for measuring psychological strain is rarely introduced by the executive board alone. It needs workplace health management to carry it professionally – and the works council to support it. Both have their own questions. We answer them on dedicated pages.

Workplace health · Safety · HR
What HSflow delivers in health management
◉
Objective data instead of self-reporting
Workplace health management mostly works with satisfaction surveys. Those fail to reach precisely the most exhausted. HSflow captures the entire workforce, without self-assessment.
⇆
Evidence that measures work
A second and third measurement show whether a measure has taken effect. An assumption becomes a documented change – also towards the executive board.
§
Fundable and connectable
German health insurers support workplace health promotion under § 20b SGB V. The same data serves § 5 ArbSchG and ESRS S1 – one measurement, several obligations.
↘
Act before return-to-work management
Structured reintegration applies from 42 days of incapacity. Mental health cases average around 40 days. Prevention reduces the case count before that threshold is reached.
Page for workplace health →
Works council · Staff council · Data protection
Why the works council can support it
Anonymity without having to fight for it
Nothing is stored that could be attributed to a person. No key, no raw records, no linkage – so § 87 (1) no. 6 BetrVG never comes into play. The works council loses no right: what it would otherwise have to push for is already built in.
✓
The procedure is co-determined
For the risk assessment under § 5 ArbSchG, § 87 (1) no. 7 BetrVG applies: methods, repetition intervals and documentation are set jointly.
↑
It can even be demanded
Under § 80 (1) no. 1 BetrVG the works council must monitor that employee-protective laws are implemented – and through its right of initiative it can call for a risk assessment itself.
Documentation for the works agreement
Process description, data flow diagram, processing agreement and the data protection assessment are provided in advance – including in direct conversation without the employer side.
