Definition of the term (“What does software validation mean?”)
Software validation is a crucial step in the development process of software applications. It ensures that the software created meets the specified requirements and quality standards.
Why is software validation important?
The software used in various industries plays a crucial role in providing services and ensuring the efficiency of business processes. Validation is intended to answer the question of whether the software is suitable for the intended purpose, whether it provides the required functionalities and whether it is sufficiently reliable and efficient, for example. Computer-aided systems play a central role in the manufacture and verification of medicinal products and medical devices. This explains why the systems must be validated from a GMP perspective.
In addition, validation provides documented proof that reproducibility can be achieved. This means that a company is able to produce an identical end product under the same conditions.
The role of regulatory requirements
In many industries, such as pharmaceuticals or medical technology, software is subject to strict regulatory requirements. Software validation helps to ensure that these requirements are met and that compliance is maintained.
For example, the GMP guidelinesstipulate that computer systems or software that support the development or manufacture of products in these industries must be validated. The software must also always be able to achieve the desired results precisely, continuously and reproducibly.
The FDA mentions the validation of software as a confirmation resulting from checks and the provision of objective proof that the software specification complies with user requirements and the intended use and that the requirements are consistently met.
Your path to digitization — Discover our software
Our digitization solutions primarily address document-based processes in manufacturing, production and quality management. The basis of the dls | eQMS is a holistic ECM/DMS system. The ECM/DMS system can be connected to your existing ERP system (e.g. SAP) and, thus, map almost all document-based processes in the company.
Steps for software validation
Software validation goes through various steps to ensure that the software meets the requirements.
- Requirements analysis: In this phase, the requirements for the software are recorded and documented in detail. This forms the basis for the entire validation process.
- Test planning and development: This is where the test plans are created that define the various test scenarios and cases. The criteria that must be met in order to complete the validation are also defined.
- Implementation of tests: The actual tests are carried out to ensure that the software functions in accordance with the requirements. This includes functional tests, performance tests and safety tests.
- Documentation: The results of the tests and all relevant information are carefully documented. This is crucial to ensure the traceability and transparency of the validation process.
Challenges in software validation
Software validation is not without its challenges. Here are some of the most common problems that can occur:
- Complexity of the software: Modern software applications are often very complex, which makes validation more difficult. It is important to use methods and tools that can deal with this complexity.
- Lack of time and resources: Validation requires time and resources, which are limited in many projects. This can lead to incomplete or insufficient validation.
- Change management: Changes to the software during the validation process can influence the results. Effective change management is therefore crucial.
Conclusion
Software validation is an indispensable process in the IT world to ensure that software applications function reliably and error-free. It also helps to fulfill regulatory requirements and ensure quality.
