In practice, objectives should focus on ensuring operational reliability combined with adherence to Quality Assurance and business processes. Project planning must coordinate multiple workstreams, departments, and parallel activities. In this context, CSA practices, SAP technical capabilities, and appropriate digital tools provide a solid and practical foundation to support this journey.
Faced with these challenges, the concept of Computer Software Assurance (CSA), widely discussed in the market, gains relevance not only as an alternative for creating and managing information, but as a necessary evolution of the system validation process. The central concept introduced, combined with dedicated risk management methodologies (both process and functional), is the application of critical thinking to each CSV step and deliverable.
How Can CSA Support SAP S/4HANA Validation?
With the CSA approach, validation in SAP projects becomes driven by the criticality of business processes and the impact that each functionality may have on product quality, regulatory compliance, and data integrity.
This means focusing testing efforts on truly critical processes such as:
- Batch traceability (from supplier to customer)
- Manufacturing operations
- Quality controls
- Product release
At the same time, lower-risk functionalities can be assessed using less rigorous approaches, while still being mapped, tested, and justified.
Additionally, CSA encourages strong coordination and reuse of documentation provided by the SAP S/4HANA implementation partner, including specifications and tests executed by the vendor and qualified integrators. This approach reduces rework for both project teams and business users, avoiding unnecessary duplication of tests and evidence.
In this context, User Acceptance Testing (UAT) can be leveraged as part of validation activities, provided it is properly assessed and justified within a structured validation strategy. These activities can also be supported by native SAP tools and exportable reports.
Paperless Tools in the CSA Approach
Paperless tools can play a strategic role in executing system validation projects, making processes more agile, traceable, and aligned with the risk-based approach widely accepted by regulatory authorities such as ANVISA, FDA, and EMA.
By replacing manual controls and paper-based documentation with integrated digital workflows, these platforms enable the centralization of the lifecycle of requirements, risk classification, test planning and execution, and deviation management, with simplified report generation supported by native traceability—all within a single controlled environment. The first major impact is related to a new way of structuring regulated information. As a consequence, operational activities are reduced, efforts are redirected toward deeper understanding of processes that are truly critical to product quality and patient safety, while embracing a new reality that ensures data integrity from its origin.
The need to revisit the information management model related to the validation process also brings another significant benefit: the possibility of reviewing and updating only the items effectively impacted by a change—such as requirements, risks, tests, and related evidence—without the need to fully review all system documentation or force the re-execution of entire test protocols. This makes the process of maintaining the validated status more agile, efficient, and sustainable.
Recently, SAP has been encouraging implementation partners to adopt tools such as:
- SAP Cloud ALM (which will mandatorily replace Solution Manager starting in 2027) to map implemented requirements and specifications, as well as to support testing phases and reporting.
- SAP Signavio for process mapping (at multiple levels of detail), including elements external to SAP HANA.
- SAP LeanIX for coordinating multiple workstreams, system landscapes, and project governance.
The application of these tools in SAP implementation projects can certainly create a solid, collaborative environment with high traceability of project activities and data. However, these global-level tools are unfortunately not capable of fully meeting all requirements from a Quality Assurance and regulatory compliance requirements.
Due to this limitation, it is highly necessary to integrate SAP’s technological environment with Quality Assurance systems, such as VLMS (Validation Lifecycle Management Systems) platforms. This integration can be achieved through direct interfaces or by enabling dynamic data exchange. Selecting the platform that best fits the project reality is crucial to strengthening the foundations and methodologies in SAP implementations, as well as in any computerized system.
For an effective implementation of CSA and paperless projects, organizations should promote a digital culture, correctly identify and simplify processes, and review how deliverables expected in Computerized System Validation are structured and managed.
PQE has extensive experience in executing SAP HANA implementation projects, applying various CSA methodologies supported by different digital platforms. If you would like to learn more, we would be pleased to exchange ideas and experiences.
