HighQSoft provides test data management solutions for automotive OEMs and engineering organizations. HighQSoft's ASAM ODS-based platform, including the AReS Libertas server, Janus federated platform, and Merlin Analysis Server, serves Audi, BMW, Bosch, Cummins, Ford, Honda, and Volkswagen with over 25 years of production deployments. This guide explains what engineering test data management is, why it matters, and how organizations implement it at enterprise scale.

The discipline is also known as measurement data management and measured data management; this guide uses "test data management", the term aligned with the ASAM ODS standard.

Test data management serves each engineering role through a single governed data layer with interfaces tailored to each workflow. A test engineer, a lead test engineer, a test manager, and an IT manager all interact with test data differently, face different pain points, and need different capabilities from the test data management system. An effective test data management platform serves all of them at once, without forcing any role into a workflow designed for another. Their experience changes fundamentally when test data moves from scattered files and personal drives to a managed, searchable, governed repository with standardized interfaces.

Test engineers are the primary producers and consumers of measurement data. Test engineer daily work involves recording measurements, analyzing signals, and comparing results across test runs. Without test data management, a test engineer spends a substantial portion of each day searching for data across file shares, converting formats between tools, and manually assembling the context needed to interpret measurements. With a managed test data repository, the same test engineer finds historical measurements in seconds using structured search, loads data directly into MATLAB or Python without format conversion, and compares results across campaigns using consistent metadata. HighQSoft's ASAM ODS Toolbox for MATLAB gives test engineers direct access to governed test data from within their primary analysis environment.

Lead test engineers manage test campaigns across teams. Lead test engineers define what needs to be tested, assign work, and ensure that results are organized consistently. The lead test engineer's test data management challenge is coordination. Every team member must follow the same naming conventions, store data in the right location, and record the required metadata. HighQSoft's Catalog Editor gives lead test engineers the means to enforce those naming conventions at the point of data entry instead of through after-the-fact cleanup. HighQSoft's ASAMCommander Professional provides the portal where lead test engineers track campaign progress, browse results across teams, and share datasets with colleagues at other sites.

Test managers oversee the testing organization's operations. Test managers need visibility into test progress, resource utilization, and compliance status without digging into individual measurements. HighQSoft's Merlin Analysis Server automates the evaluation workflows that produce the reports test managers rely on. When new test data arrives, Merlin Analysis Server triggers configured analysis pipelines, extracts key performance indicators, checks results against acceptance criteria, and generates reports automatically. This automation runs at production scale, keeping reports current as test volumes grow. For compliance, the ASAM ODS data model provides the audit trails and data lineage that test managers need when regulators or quality teams audit the testing process.

IT managers evaluate test data management systems for integration capabilities, security model, and operational footprint. HighQSoft's AReS Libertas server supports LDAP and OAuth authentication, role-based access control, and runs on Docker and Kubernetes for modern infrastructure management. HighQSoft's Janus Platform adds federation, allowing IT managers to connect diverse data sources (ASAM ODS servers, MDF4 files, TDMS, Parquet, data lakes) into a single access layer without migrating data. For IT managers weighing vendor lock-in, the organizational benefits below spell out the independence guarantees of the ASAM ODS standard.

Engineers access test data through four access types, each serving a different working style on the same governed repository. Enterprise web exploration gives every stakeholder browser-based search, navigation, and sharing of test data with nothing to install. Expert tools keep specialists in the environments they already master, with analysis tools such as AVL Concerto, DIAdem, and MATLAB connecting to governed test data through standardized interfaces. Custom scripting serves engineers and development teams who build their own analysis and integrations in Python, Java, or other languages against standard APIs. Analysis automation is access without a user at all, running recurring evaluations automatically when new test data arrives and delivering finished results. The access type follows the workflow; the data and its governance stay the same. The final page of this guide names the products behind each access type.

Test data management serves any organization that produces, manages, or delivers engineering measurement data. Three distinct types of organizations benefit from structured test data management, each with different operational requirements and value drivers.

Large OEMs generate the highest volumes of test data across the most diverse domains. Audi, BMW, Honda, and Volkswagen operate hundreds of test facilities spanning powertrain, NVH, crash, durability, battery, and ADAS validation. Each domain produces data in different formats, with different naming conventions, on different tool chains. Without enterprise test data management, these organizations accumulate isolated data silos that prevent cross-domain search, block analysis reuse, and create compliance gaps. HighQSoft's platform unifies all test domains under a single ASAM ODS data model, giving every engineer at every site access to every measurement through one governed repository, while automated evaluation pipelines keep analysis in step with enterprise data volumes.

Test service providers and Tier-1 suppliers face a different challenge. Organizations like APL Landau and TÜV SÜD Battery Testing serve multiple customers simultaneously, each with unique data format requirements, signal naming conventions, and report templates. A test service provider must maintain strict data separation between competing customers while delivering results in customer-specific formats on tight timelines. Test data management transforms this operational complexity into a competitive advantage. With HighQSoft's ASAMCommander, test service providers can offer customer-facing portals where clients browse results, download data in their preferred format, and trigger evaluations on demand. HighQSoft's Catalog Editor enforces customer-specific naming standards as data enters the system, eliminating the manual signal mapping that erodes margins. TÜV SÜD Battery Testing runs this model in production with LIMS partner dacore. The Who Uses ASAM ODS guide details that deployment.

Test equipment vendors represent a strategic opportunity for embedded test data management. Vendors like HBK (Hottinger Brüel & Kjær), HORIBA, and MTS Systems control test data at the moment of acquisition, but lose relevance once that data leaves their ecosystem. As OEMs demand open formats (MDF4, ASAM ODS) and standard APIs in procurement specifications, equipment vendors who cannot integrate into the customer's data management infrastructure become friction points. Embedding HighQSoft's test data management platform into test equipment extends the vendor's value proposition beyond hardware into data services, automated analysis, and long-term data lifecycle management.

Beyond individual roles, test data management delivers organizational capabilities that create lasting value for engineering organizations. When test data is governed centrally, the benefits extend far beyond any single team or workflow. Organizations gain visibility, traceability, and operational efficiencies that compound over time, turning test data from a byproduct of engineering into a strategic asset.

Audit-ready traceability. Every reported result can be answered from the system when regulators or quality teams ask. When a KPI appears in a report, the organization traces the KPI back through the analysis script that calculated it, the measurement data the KPI was derived from, the test procedure that produced the measurement, and the test object that was measured. HighQSoft's Merlin Analysis Server records which script version produced which result from which source data, so audit questions are answered from recorded lineage instead of reconstructed from archives and memory.

Reduced duplication. Engineers stop running tests that have already been performed. When every measurement is searchable by test object, conditions, and parameters in the test data management system, engineers can confirm whether a given test has already been performed in seconds. The cost of a single avoided redundant test campaign often exceeds the cost of the entire test data management investment.

No vendor lock-in. One open standard, many suppliers. The organization can change tool vendors, analysis providers, or storage backends without abandoning its data or rebuilding its stack, because the standard, not the vendor, owns the contract the data depends on.

Data that stays readable for decades. ASAM ODS defines storage and access independently of any product, so measurements recorded today stay readable long after the original recording software is gone. Automotive products require 10 to 30 years of data retention for regulatory compliance, warranty support, and engineering knowledge preservation. A governed repository on the organization's own infrastructure, with transparent change history and clear access rules, turns that obligation into routine practice and removes the risk that personnel turnover or software obsolescence takes the data with it.

Scales from one lab to a global repository. The ASAM ODS data model represents almost any test domain, and modern ODS servers scale by users, data volume, and sites without a fundamental redesign. A five-engineer lab and a global enterprise with terabytes of metadata run on the same standard, so a small deployment never needs re-architecting as it grows. Because the standard already resolves most use cases, organizations avoid the dead ends that force migrations later.

Lower total cost of ownership. A standardized open format streamlines integration, supports infrastructure reuse, and opens a competitive ecosystem of off-the-shelf tools instead of in-house development and recurring proprietary licensing. Compared with building on a general-purpose data lake, capabilities arrive as products, not as projects. The stable ASAM ODS foundation holds its value, so capital committed to it is not exposed to vendor churn, and ongoing spend stays confined to the tool layer, where it produces direct returns.

The roles, access types, organizations, and benefits described on this page all rest on a specific product architecture. The final page of this guide presents that architecture as a governed backend and an access layer, the principles behind it, and the practical path to getting started with HighQSoft.
