The Challenge: Unstructured Onboarding Feedback

Most HR teams invest heavily in onboarding, but the feedback from new hires is fragmented and unstructured. Comments sit in open-ended survey fields, manager notes, onboarding interviews, Slack chats and random emails. Each interaction contains valuable signals about what works and what doesn’t, yet no one has the time to read everything end-to-end. As a result, HR leaders struggle to answer basic questions: Which locations are struggling? Which steps confuse people? Where do new hires feel unsupported?

Traditional approaches rely on quantitative survey scores and manual reading of free-text comments. Score dashboards look neat but hide the nuance behind a simple 1–5 rating. Manually reading hundreds of comments or interview transcripts is time-consuming, inconsistent, and often delegated to whoever has a spare afternoon. By the time someone has synthesized insights, the next onboarding cohort has already passed through the same broken process.

The impact is tangible. Without a clear view of patterns in onboarding feedback, issues repeat across cohorts, time-to-productivity stays higher than it needs to be, and managers burn time answering the same questions for each new hire. New employees experience avoidable friction in their first weeks, which can hurt engagement and even increase early attrition. From a business perspective, this means slower ramp-up, higher hidden onboarding costs, and a weaker employer brand compared to organizations that learn fast from every cohort.

This challenge is very real, but it’s also highly solvable. Modern AI feedback analysis makes it possible to read every comment, every transcript and every chat message at scale—without adding more workload to HR. At Reruption, we’ve helped teams replace manual, anecdote-based improvement loops with data-backed, AI-supported decision-making. In the rest of this page, you’ll see how to use Claude specifically to make sense of unstructured onboarding feedback and turn it into a continuous improvement engine.

Our Assessment

A strategic assessment of the challenge and high-level tips how to tackle it.

From Reruption’s work building AI-first HR workflows, we’ve seen that Claude is particularly strong when you need to analyse long-form, narrative onboarding feedback—think open text survey answers, interview transcripts or Slack conversations with new hires. Instead of just adding another tool, the goal should be to embed Claude into your onboarding feedback process so that HR and people leaders can get structured insights, risk alerts and clear summaries without reading every single line themselves.

Treat Feedback Analysis as a Continuous System, Not a One-Off Project

Many HR teams approach onboarding feedback analysis as a quarterly or annual exercise. With Claude, it’s more powerful to think in terms of a continuous loop: every new comment, survey response or interview feeds into a living knowledge base. Strategically, this shifts your mindset from “reporting” to “learning system” and makes it easier to act on insights while they still matter for active cohorts.

Design the operating model before you design prompts. Decide who will own the AI-generated insights, how often they should be reviewed, and how changes to the onboarding journey will be logged and measured. When Claude is embedded in this cadence—e.g. weekly summaries for HRBPs and monthly pattern reviews for leadership—you build a muscle of data-driven onboarding improvements instead of sporadic clean-ups.

Align HR, IT and Data Privacy Early

Using Claude for HR feedback analysis touches sensitive data: names, performance signals, personal stories. Strategically, that means HR cannot implement it in isolation. Bring IT, data protection, and work councils (where applicable) in early, and co-design guardrails for what data is processed, how it is pseudonymised, and how outputs can be used.

This alignment step is not just about compliance; it’s about trust. New hires and managers are more likely to share honest feedback if they know that AI is being used responsibly. At Reruption we emphasise an AI governance framework from day one: clear retention rules, access control, and transparent communication in your onboarding materials about how feedback is analysed and for what purpose.

Start with One High-Value Feedback Stream

It’s tempting to pour every historical survey, email and chat log into Claude on day one. A more strategic path is to start with a single, high-signal stream—often open-ended onboarding survey responses or structured “first 30 days” interviews. This lets you prove value quickly, refine your prompts, and build internal confidence before connecting additional data sources.

By scoping the initial use case tightly (e.g. “understand the top 5 recurring friction points in the first 2 weeks”), HR gains concrete wins and learns how to work with AI-generated insights. Once this workflow is stable, it’s much easier to extend Claude’s role to chat transcripts, exit interviews or manager notes without overwhelming the team.

Define What ‘Good Insight’ Looks Like for Stakeholders

Claude can generate endless summaries, but not all summaries are equally useful. Strategically, you need to define what good looks like for each stakeholder: HR ops might want root-cause analysis and process gaps, managers may prefer concrete action items, and leadership will care about trends, risks and impact on time-to-productivity.

Capture these needs upfront and translate them into different “analysis profiles” in Claude prompts. For example, one prompt template for HR analytics, another for senior leadership reports, and a third for manager-level onboarding retros. This alignment ensures that Claude’s output flows directly into decisions and changes, instead of becoming another report nobody reads.

Invest in Capability Building, Not Just a Tool Rollout

The long-term value of using Claude for unstructured onboarding feedback depends on how well your team can interpret and act on AI insights. Strategically, that means training HR staff to work with AI as a thinking partner: questioning insights, asking for alternative explanations, and combining qualitative AI analysis with quantitative HR metrics.

Plan explicit enablement: short trainings on prompt design, reviewing AI outputs critically, and integrating findings into your onboarding governance. This reduces dependency on external experts and ensures that your HR team can continuously evolve the AI setup as your onboarding process and organisation change.

Using Claude for onboarding feedback analysis is less about fancy dashboards and more about building a reliable, repeatable way to learn from every new hire’s experience. When you combine clear roles, strong data governance and targeted analysis profiles, Claude can turn scattered comments into focused improvements that shorten ramp-up time and strengthen your employer brand. Reruption’s AI engineering and Co-Preneur approach are designed to help HR teams stand up these workflows quickly, test them via an AI PoC, and scale them confidently—if you’d like to explore what this could look like in your environment, we’re happy to discuss specific options with your team.

Real-World Case Studies

From Healthcare to Retail: Learn how companies successfully use Claude.

Duke Health

Healthcare

Sepsis is a leading cause of hospital mortality, affecting over 1.7 million Americans annually with a 20-30% mortality rate when recognized late. At Duke Health, clinicians faced the challenge of early detection amid subtle, non-specific symptoms mimicking other conditions, leading to delayed interventions like antibiotics and fluids. Traditional scoring systems like qSOFA or NEWS suffered from low sensitivity (around 50-60%) and high false alarms, causing alert fatigue in busy wards and EDs. Additionally, integrating AI into real-time clinical workflows posed risks: ensuring model accuracy on diverse patient data, gaining clinician trust, and complying with regulations without disrupting care. Duke needed a custom, explainable model trained on its own EHR data to avoid vendor biases and enable seamless adoption across its three hospitals.

Lösung

Duke's Sepsis Watch is a deep learning model leveraging real-time EHR data (vitals, labs, demographics) to continuously monitor hospitalized patients and predict sepsis onset 6 hours in advance with high precision. Developed by the Duke Institute for Health Innovation (DIHI), it triggers nurse-facing alerts (Best Practice Advisories) only when risk exceeds thresholds, minimizing fatigue. The model was trained on Duke-specific data from 250,000+ encounters, achieving AUROC of 0.935 at 3 hours prior and 88% sensitivity at low false positive rates. Integration via Epic EHR used a human-centered design, involving clinicians in iterations to refine alerts and workflows, ensuring safe deployment without overriding clinical judgment.

Ergebnisse

  • AUROC: 0.935 for sepsis prediction 3 hours prior
  • Sensitivity: 88% at 3 hours early detection
  • Reduced time to antibiotics: 1.2 hours faster
  • Alert override rate: <10% (high clinician trust)
  • Sepsis bundle compliance: Improved by 20%
  • Mortality reduction: Associated with 12% drop in sepsis deaths

NYU Langone Health

Healthcare

NYU Langone Health, a leading academic medical center, faced significant hurdles in leveraging the vast amounts of unstructured clinical notes generated daily across its network. Traditional clinical predictive models relied heavily on structured data like lab results and vitals, but these required complex ETL processes that were time-consuming and limited in scope. Unstructured notes, rich with nuanced physician insights, were underutilized due to challenges in natural language processing, hindering accurate predictions of critical outcomes such as in-hospital mortality, length of stay (LOS), readmissions, and operational events like insurance denials. Clinicians needed real-time, scalable tools to identify at-risk patients early, but existing models struggled with the volume and variability of EHR data—over 4 million notes spanning a decade. This gap led to reactive care, increased costs, and suboptimal patient outcomes, prompting the need for an innovative approach to transform raw text into actionable foresight.

Lösung

To address these challenges, NYU Langone's Division of Applied AI Technologies at the Center for Healthcare Innovation and Delivery Science developed NYUTron, a proprietary large language model (LLM) specifically trained on internal clinical notes. Unlike off-the-shelf models, NYUTron was fine-tuned on unstructured EHR text from millions of encounters, enabling it to serve as an all-purpose prediction engine for diverse tasks. The solution involved pre-training a 13-billion-parameter LLM on over 10 years of de-identified notes (approximately 4.8 million inpatient notes), followed by task-specific fine-tuning. This allowed seamless integration into clinical workflows, automating risk flagging directly from physician documentation without manual data structuring. Collaborative efforts, including AI 'Prompt-a-Thons,' accelerated adoption by engaging clinicians in model refinement.

Ergebnisse

  • AUROC: 0.961 for 48-hour mortality prediction (vs. 0.938 benchmark)
  • 92% accuracy in identifying high-risk patients from notes
  • LOS prediction AUROC: 0.891 (5.6% improvement over prior models)
  • Readmission prediction: AUROC 0.812, outperforming clinicians in some tasks
  • Operational predictions (e.g., insurance denial): AUROC up to 0.85
  • 24 clinical tasks with superior performance across mortality, LOS, and comorbidities

Best Practices

Successful implementations follow proven patterns. Have a look at our tactical advice to get started.

Consolidate and Pseudonymise Feedback Before Sending It to Claude

Start by bringing your main onboarding feedback sources into one place—this could be a secure HR data store or a simple internal database. Typical sources include open-text survey responses, notes from onboarding check-ins, emails to HR, and relevant Slack/Teams threads. Standardise the format into a simple schema (e.g. date, country, role, source, text) so Claude can analyse consistently.

Before sending any data to Claude, remove or pseudonymise personal identifiers. Replace names with role labels (e.g. “New Hire – Sales, DE”), strip out direct contact details and any sensitive personal health information. This can be done via a small script or internal tool that runs as part of your feedback ingestion pipeline and ensures that privacy-by-design is integrated into your AI workflow.

Use a Baseline Prompt to Cluster Pain Points Across Cohorts

Create a reusable core prompt that tells Claude exactly how to analyse onboarding feedback. The goal is to group similar issues, quantify how often they appear, and capture representative quotes. Here is a practical example you can adapt:

System: You are an HR onboarding analytics assistant.
Task: Analyse the following new-hire onboarding feedback.

1) Identify the 5-10 most frequent pain points and friction areas.
2) For each pain point, provide:
   - A short label
   - Description
   - Estimated frequency (High/Medium/Low)
   - Typical moments when it occurs (e.g. before day 1, week 1, week 4)
   - 2-3 representative anonymised quotes.
3) Highlight any high-risk topics (e.g. compliance, safety, discrimination).
4) Suggest 3-5 concrete improvements to the onboarding process.

Output in concise, structured sections.

Feed Claude a batch of recent feedback (e.g. one month or one cohort) through this prompt. The result should be a clear list of recurring pain points and associated risks that HR can review and prioritise.

Create Role-Specific Summaries for Hiring Managers and HRBPs

Once you have clustered insights, generate targeted summaries for the people who can act on them. For example, hiring managers might want to know what their new joiners in Sales struggle with in the first week, while HRBPs might care about location-specific themes. Use Claude to transform the same analysis into multiple stakeholder views.

Here is an example prompt for managers:

System: You help managers improve onboarding for their teams.

User: Based on the analysis below, create a 1-page summary for hiring managers in <DEPARTMENT>.
Focus on:
- Top 5 friction points specific to this department
- What managers can do differently next time
- 3 questions managers should ask in their next 1:1 with new hires.

Analysis:
<Paste clustered insights from previous step>

This keeps communication actionable and avoids overwhelming managers with full analytic reports.

Integrate Claude into Your Onboarding Retrospective Cadence

Make Claude part of a regular onboarding retrospective, rather than ad-hoc analysis. For example, schedule a monthly or cohort-based routine where HR exports the latest unstructured feedback, runs the standard analysis prompt, and then uses a follow-up prompt to produce a slide or short report for your onboarding steering group.

An example follow-up prompt:

System: You create executive-ready onboarding insight summaries.

User: Turn the following Claude analysis into a short slide outline for the monthly onboarding review.
Include:
- Key trends since last month
- Emerging risks
- 3 prioritised improvement actions (with expected impact)

Analysis:
<Paste Claude's clustered output>

This consistent rhythm ensures that insights feed into decisions about content updates, checklist changes, and stakeholder training.

Use Claude to Cross-Link Qualitative Feedback with Quantitative KPIs

Combine Claude’s qualitative insights with your HR metrics to understand business impact. For each cohort or period, provide Claude with a short table of KPIs—such as time-to-productivity, completion rates for mandatory training, early attrition, or engagement scores—and ask it to relate patterns in feedback to these metrics.

Example prompt:

System: You are an HR analytics assistant.

User: Here is onboarding feedback analysis and key KPIs.
1) Suggest possible relationships between pain points and KPIs.
2) Highlight where improving a specific issue might most reduce time-to-productivity or early attrition.
3) Flag any data limitations or alternative explanations.

Feedback analysis:
<Paste Claude's clustered insights>

KPIs:
- Avg time to first closed ticket (Support): 18 days
- Early attrition (0-90 days): 6.5%
- Mandatory training completion by day 30: 72%

This helps HR make a stronger case for onboarding improvements linked to measurable outcomes.

Automate Risk Alerts from High-Risk Feedback Themes

Configure a workflow where particularly sensitive themes—such as safety issues, discrimination, or compliance gaps—are automatically flagged at a higher priority. Practically, you can ask Claude to tag each feedback entry with risk categories and confidence scores, and then route high-risk items to a secure review queue.

Prompt snippet:

System: Classify onboarding feedback by risk.

User: For each feedback item, output:
- Risk level: High / Medium / Low
- Category: Compliance, Safety, Wellbeing, Manager behaviour, Other
- One-sentence rationale.

Feedback:
1) ...
2) ...
3) ...

Connect this with your existing ticketing or case management systems so that critical issues are handled by HR or Compliance within a defined SLA, while still benefiting from Claude’s ability to scan large volumes of text.

When implemented with these practices, organisations typically see faster detection of onboarding issues, a more targeted improvement backlog, and better alignment between qualitative feedback and HR KPIs. Over a few cohorts, it’s realistic to aim for measurable improvements such as a 10–20% reduction in time-to-productivity for key roles, higher new-hire satisfaction scores for the first 30 days, and fewer repeated issues surfacing across cohorts.

Frequently Asked Questions

Claude can read and synthesise large volumes of free-text onboarding feedback that HR teams don’t have time to manually go through. This includes open survey comments, onboarding interview notes, and chat transcripts from tools like Slack or Teams.

By clustering recurring pain points, highlighting high-risk themes, and proposing concrete improvements, Claude turns scattered qualitative feedback into structured insight that HR can act on. Instead of a pile of comments, you get clear themes, representative quotes, and prioritised recommendations for your onboarding process.

You typically need three ingredients: an HR owner for the onboarding feedback process, basic technical support to connect your feedback sources, and someone who can design and iterate prompts (this can be HR with minimal training). You do not need a large data science team to get started.

A common setup is: HR defines questions and desired outputs, IT ensures secure data access and pseudonymisation, and an AI-savvy HR or analytics person works with Claude and Reruption to refine prompts and workflows. We often help clients stand up a working prototype in a few weeks and then hand over clear playbooks so HR can run it day-to-day.

On the analysis side, results are almost immediate: once your feedback data is consolidated, Claude can produce initial insight reports within days. Many organisations get their first round of clustered pain points, risks and improvement ideas during an initial 2–3 week pilot.

Impact on onboarding metrics like time-to-productivity or new-hire satisfaction naturally takes longer, because you need at least one or two cohorts after changes are implemented to measure improvements. Realistically, you can expect early process fixes within the first month and clearer metric shifts over 3–6 months, depending on your hiring volume and onboarding cycle.

Yes, in most organisations it is. The main cost drivers are Claude usage (API or platform), some light engineering to connect your feedback sources, and internal time for HR to review and act on insights. In return, you reduce manual reading and ad-hoc analysis time and can target improvements where they have the biggest effect on time-to-productivity and early attrition.

For example, if Claude helps you identify and fix a recurring onboarding issue that delays full productivity by a week for dozens of new hires per year, the saved manager time and faster ramp-up can far exceed the operational cost of running the AI workflow. Reruption helps you model this ROI upfront so you can decide how deep to go.

Reruption works with a Co-Preneur approach: we don’t just advise, we embed alongside your HR and IT teams to ship a working solution. Our AI PoC offering (9,900€) is a structured way to prove the value of using Claude on your onboarding feedback before you commit to a broader rollout.

In the PoC, we help you define the use case, connect sample data securely, select and refine Claude prompts, and build a lightweight prototype that produces concrete insights and reports. We then evaluate performance (quality, speed, cost per run) and provide a roadmap for productionising the workflow. If you choose to go further, we support implementation, governance and enablement so your HR team can operate and evolve the solution independently.
