WHEN IS AN ASSESSMENT USEFUL?

When technical questions become the basis for decisions.

With long-established software, it is often not immediately clear whether a problem is caused by a technical defect, a changed requirement, missing documentation or the system structure that has evolved over many years. A structured technical investigation creates a traceable basis for further decisions.

Delivered functionality

Which functions are actually available, and how do they compare with documented or agreed requirements?

Documentation

Are structure, functions, interfaces and technical relationships sufficiently understandable to a qualified third party?

Maintainability

Which technical dependencies, outdated components or critical areas make changes and reliable operation more difficult?

Effort

Are development, remediation or modernization efforts technically plausible, and which risks affect the estimate?

EXPERT SERVICES

From technical investigation to a clear assessment.

01

Technical software analysis

Investigation of the current software state.

  • Source code and architecture
  • Databases and data access
  • Interfaces and dependencies
  • Technology and operational risks
Result: documented technical findings
02

Target / actual comparison

Traceable comparison of requirements and delivered functionality.

  • Functional scope
  • Requirements documentation
  • Identifiable deviations
  • Technical classification
Result: transparent comparison
03

Documentation review

Assessment of existing technical documentation in the context of the system under review.

  • System and program description
  • Schnittstellen
  • Data structures
  • Traceability
Result: reasoned assessment
04

Technical opinion

Structured presentation of the evidence basis, findings and professional assessment.

  • Private expert report
  • Technical second opinion
  • Plausibility review
  • Modernization assessment
Result: clear basis for decision-making

APPROACH

Technical findings. Meaning. Assessment. Recommendation.

Technical details are not presented in isolation. What matters is what a finding means for operations, contractual performance, maintainability or an upcoming investment decision.

01

Question

Clearly define the subject of the review and the technical questions to be answered.

02

Evidence basis

Record the software state, source code, documentation and other evidence.

03

Investigation

Examine relevant functions, structures, dependencies and technical facts.

04

Assessment

Clearly separate findings from assumptions and professional assessment.

05

Report

Document results in a traceable way that non-technical decision-makers can understand.

06

Discussion

Explain results and answer outstanding technical questions in a structured manner.

PRACTICAL EXPERIENCE

Long-established software from a developer and leadership perspective.

I have been developing and taking responsibility for software solutions since 1987. A significant part of my career has involved specialized POS and industry systems that had to be continuously developed and kept reliable in day-to-day operations over many years. This experience forms the basis of my current specialization in legacy and custom software.

Transparency regarding expert status

Services are provided as an independent IT expert. I am currently not publicly appointed and sworn by a German Chamber of Industry and Commerce (IHK).

INITIAL ASSESSMENT

Which technical question needs to be answered?

In an initial conversation, we clarify the subject of the review, available documentation and whether an independent technical investigation can be carried out meaningfully.
