AI in business practice

AI case studies:
What works in practice.

Which use cases create real value? How do data become reliable answers, and prototypes become securely integrated systems? Find concrete examples and informed answers to plan your AI project.

Three application areas

From knowledge and images
to customer service.

A good case study starts with a clear task. These examples show how AI can help employees day to day without promising more than can be reliably verified.

01

Knowledge management · RAG

Make business knowledge reliably accessible

Starting point
Key information is scattered across documents and individual employees' experience.
Solution approach
MemoWerk searches approved sources semantically and provides answers with traceable references.
Impact
Information is found faster, answers can be verified and knowledge becomes usable independently of individuals.
02

Image recognition · Service process

Identify spare parts from a photo

Starting point
Service technicians must identify a component on site and match it to the right catalogue item.
Solution approach
Hauer Lift Lens analyses a photo of a lift part and leads to the appropriate ordering process.
Impact
Visual search shortens the path from identification to ordering and helps staff directly on site.

03

AI agent · Support

Answer specialist and product questions consistently

Starting point
Recurring support questions occupy specialists while relevant knowledge is spread across sources.
Solution approach
A specialised AI agent uses approved expertise and product knowledge, understands the request and prepares an appropriate answer.
Impact
Routine questions are handled faster; complex cases remain with the responsible specialists.

Questions & answers

What decision-makers should know about AI case studies.

Key questions about value, feasibility, data, security and production operations.

What is an AI case study?

An AI case study documents a concrete business challenge, the chosen solution, integration into processes and systems and verifiable results, beyond a model or demo.

It is meaningful when prerequisites, quality criteria and limitations are visible, helping you assess what applies to your business.

Which AI use cases suit SMEs?

Start with clearly bounded, frequent, knowledge-intensive tasks: document search and review, service enquiries, classification, image recognition or preparing steps across systems.

Technology alone is not decisive. Assess expected value, data quality, frequency, error risk and integration effort.

How is AI project success measured?

Metrics come from the process and are set before development. Depending on the application, they may include handling time, accuracy, answer quality, resolution rate, error rate, adoption or the share of correctly prepared cases.

A baseline, representative tests and expert acceptance make assessment reliable. For generative AI, “sounds good” is not enough.

How long does AI implementation take?

It mainly depends on data access, process scope, interfaces and protection needs. A bounded prototype can often demonstrate viability within a few weeks.

Production also needs testing, roles and permissions, robust interfaces, monitoring, documentation and employee involvement. Planning should distinguish prototyping from production rollout.

How does evival protect confidential business data?

Protection is designed for the use case, including data minimisation, controlled access, suitable deployment, encryption, logging and clear retention rules.

We select models and providers by task and protection requirements. Where errors could have serious consequences, we add safeguards and human approvals.

Can AI integrate with existing ERP, CRM and DMS solutions?

Yes. Through APIs and secure interfaces, AI can use system information, return results or prepare defined work steps.

AI receives only necessary permissions. Existing roles, access rules and checks remain authoritative; critical actions can require human confirmation.

What distinguishes a prototype from production AI?

A prototype tests feasibility: does the approach work with realistic data and defined test cases? Its scope may deliberately be limited.

Operations add reliable interfaces, identities, permissions, quality monitoring, error handling, privacy, documentation and clear responsibilities. These unseen elements turn a demo into a dependable system.

When does RAG make sense for business knowledge?

RAG suits answers based on approved, regularly changing company sources. Before answering, the system retrieves relevant content and provides it as context to the language model.

That does not automatically make answers correct. Sources, access controls, good documents and systematic evaluation remain essential.

When do AI agents make sense, and when not?

Agents suit goals requiring several traceable steps, such as finding information, checking a case and preparing an action. Tools, rights and stopping rules must be narrowly defined.

For fixed, fully rule-based workflows, conventional automation is often simpler and more reliable. Combining workflows, software logic and AI may be best.

What role do employees play in an AI case study?

Employees know exceptions, quality standards and real bottlenecks. Their experience helps select use cases, build tests and assess results.

Early involvement improves usability and adoption. The aim is a sensible division of tasks between people and systems.

Use case selection

What makes an AI use case viable?

The best projects combine a real bottleneck with accessible data, measurable quality and manageable risk.

  1. 01

    Relevant problem

    The task regularly consumes time, causes errors or prevents effective use of knowledge.

  2. 02

    Suitable data

    Required documents, images or case data are available, lawfully usable and sufficiently representative.

  3. 03

    Verifiable result

    Quality and business value can be assessed with concrete tests and metrics.

  4. 04

    Manageable risk

    Error consequences are understood and controlled through roles, safeguards and human approvals.

The path to reliable results

Understand. Test. Integrate. Improve.

01

Understand the process

Clarify the problem, participants and goals together.

02

Test feasibility

Evaluate with realistic data and measurable criteria.

03

Integrate securely

Make interfaces, permissions and approvals production-ready.

04

Improve quality

Monitor usage and results and improve continuously.
