Static analysis and dynamic testing: What are the strengths and weaknesses?

Veröffentlicht Veröffentlicht in Englische Blogs, Validation and Verification

Static analysis and dynamic testing: Even after several decades of software engineering, we still far away from guaranteed error-free software. Even for software developed to the highest safety standards, no one can guarantee absolute freedom from errors. All functional safety standards recognize that a guaranteed error-free software (with the current state of the technology) cannot […]

Requirement Engineering 2.0 – Approaches how the method needs to be enhanced!

Veröffentlicht Veröffentlicht in Englische Blogs, Requirements Engineering eng

Many books have been written in the last 30 years on the subject of requirement engineering. The method has been designed and improved. The great success of these efforts lies in the fact that the awareness of the topic has been raised in a broad professional audience. There is hardly anyone today who would fundamentally […]

Risk-based testing: Method for identifying the right test cases

Veröffentlicht Veröffentlicht in Englische Blogs, Validation and Verification

There is no such thing as bug-free software! Nevertheless, software is successfully used even in very critical systems. The software development processes have become so mature that it is possible to reduce the number of errors in the software reliably to such an extent that the number of system errors which have their cause in […]

ISO 26262 Confidence in the use of software tools – A feasible strategy!

Veröffentlicht Schreibe einen KommentarVeröffentlicht in Automotive, Englische Blogs

ISO 26262 Confidence in the use of softwar tools: ISO 26262-8 in chapter 11 defines the requirements for software tools that are used in an ISO 26262 compliant software development process. In the practical usage of chapter 11 of ISO 26262-8 many questions often arise, which partly lead to very creative approaches regarding tool qualification. […]

Comparison and evaluation of different test design techniques

Veröffentlicht Veröffentlicht in Englische Blogs, Validation and Verification

Test design techniques: The complexity of technical systems has been increasing for years and there is no foreseeable end to this. The crucial driver of innovation is software. Very powerful hardware in combination with complex software are the basis for trends such as IOT, autonomous driving, Smart Home and human-robot collaboration, to list just a […]

EN 50129 Safety Case

Veröffentlicht Veröffentlicht in Englische Blogs, Railway

The EN 50129 safety case is the structured and documented safety statement that the conditions for safety acceptance have been fulfilled. The safety case includes all safety-relevant aspects of the product life cycle. When creating the document, the challenge is therefore to present a wide range of information in a clear and comprehensible manner. EN […]

ISO 21448 – Safety of the Intended Functionality (SOTIF) Why is it required?

Veröffentlicht Veröffentlicht in Automotive, Englische Blogs

The ISO 21448 Safety of the Intended Functionality defines methods for failure resulting from the limitation of a functionality. ISO 26262 deals with concepts, procedures and measures for failures resulting from random hardware failures or systematic HW/SW failures. Many experts see the SOTIF standard as a normative support for the realization of autonomous driving. This […]

ISO 25119: Software Development for Tractors and Machinery for agriculture and forestry

Veröffentlicht Veröffentlicht in Englische Blogs, Other FuSaNorms

ISO 25119: The norm describes the safety requirements for tractors and machinery for agriculture and forestry. The standard is a sector specific implementation of IEC 61508 and consists of 4 parts. Like other functional safety standards, ISO 25119 specifies various levels of criticality. The standard defines the Agricultural Performance Level (AgPL) QM, a – e. […]
