Introduction – Flood of Data vs. Knowledge Gaps

Did you know that medium-sized companies generate immense amounts of unstructured text data per year? This hides crucial facts – but classic business intelligence approaches often only exploit a fraction of the potential of this data.

In this article, we want to provide decision-makers with a clear roadmap for combining Retrieval-Augmented Generation (RAG) and our DeepResearch loop to enable in-depth analysis based solely on 100% internal knowledge – without web search and without data drain.

1 | What does RAG do?

RAG extends large language models with a targeted search step. Before the model responds, it gets text passages from your own sources – project reports, mails or tickets – and embeds them as context. The result is fact-based answers, whose precision can be significantly increased compared to “pure” LLM answers according to studies.

Note: RAG brings the facts into the model, not the model to the facts.

2 | What complements DeepResearch?

RAG answers a question solidly – but remains with a one-time research. However, complex business questions require iterative deepening.

RAG therefore extends our DeepResearch loop with these steps and saved 70% analysis time per use case in the field test Ø:

  • Defining the question – e.g. “Which cost and risk drivers can we find in all projects over the last five years?”
  • First RAG search – Automatic extraction of relevant passages.
  • Synthesis & Reasoning – Pattern recognition (e.g. Ø cost deviation +10%).
  • Deepening issues – focused follow-up questions (“Which projects were +20%? Why?”).
  • Targeted Search (RAG) – only where context is missing, is searched again.
  • Sufficiency check Ends only when ≥ 90% source coverage is reached.
  • Final Report Structured analysis with metrics, causes, recommendations for action

3 | The integrated analysis process at a glance

Question: “Which types of projects cause the highest additional costs?”

Phase Purpose Results
1 Question Sharpening business objectives Clear hypothesis
2 Retrieve Finding relevant internal documents Context snippets
3 Generates Derive trends and patterns Preliminary insights
4 loop Closing knowledge gaps Extended data set
5 Check Sufficiency and plausibility testing Validated basis
6 Report Structuring results Decision-Mature output

4 | Practical example: 100 internal customer projects (2019-2024)

Question: “Which types of projects cause the highest additional costs?”

Project type Ø Actual/target deviation Main drivers
Hardware +12 % Late delivery (37 %), change (*)
Software +7 % Scope Creep (42%), bug fixes
Consulting services +3 % Additional workshops, travel expenses

*Change = short-term change of specifications.

Recommendation for action:

  • Early risk monitoring in hardware projects (supply chain KPIs, buffer times).
  • Change Control Board for software projects to limit scope-creep.

5 | Business Benefits at a Glance

Benefit factor Measurement variable Result (pilot)
Depth instead of surface Identified root cases 5x more than manual
Transparent sources Audit Trail Completeness 100 %
Data protection and compliance External data flows 0 bytes
Efficiency Analysis throughput time -70 %

6 | Conclusion

  • RAG provides reliable facts from your data base.
  • DeepResearch transforms these facts through iterative deepening into action-relevant insights.
  • 100 % internal sources ensure data sovereignty, compliance and trust.
