Weak growth is sharpening investment scrutiny as expanding AI regulation raises expectations for governance and data control, ISG Provider Lens report says
German enterprises are making application development and maintenance (ADM) programs more selective, shifting from adding development capacity to reducing technical debt and using AI within more structured delivery models, according to a new research report published today by Information Services Group (ISG) (Nasdaq: III), a global AI-centered technology research and advisory firm.
The 2026 ISG Provider Lens AI-driven ADM Services report for Germany finds that weak economic conditions are reshaping project priorities rather than causing a broad retreat from technology spending. Application modernization and AI enablement have remained more resilient than generic custom development. Broader regulations under the EU AI Act that took effect in August 2026 are also increasing attention to documentation, auditability and control over sensitive enterprise data.
"AI is expanding what enterprises can automate, but it also makes delivery discipline more important," said Matthias Paletta, director at ISG. "German buyers want productivity gains they can measure without weakening quality or accountability."
As AI-enabled toolchains connect work across the application lifecycle, traditional boundaries among application development projects, managed services and quality assurance are becoming less distinct. Enterprises are responding with build-run-improve models that embed testing and transition-to-run earlier in the process.
German buyers are moving away from buying services as person-days of labor and toward contracts linked to software outcomes. ADM agreements are likely to include clearer baselines for cycle time, defect rates and modernization throughput. Sovereignty is becoming a more important sourcing factor because AI-enabled ADM can involve sensitive source code, proprietary process logic and enterprise data. Buyers are placing greater weight on EU hosting and the use of transparent models, especially in regulated sectors.
Local delivery capabilities remain important as ADM work expands beyond coding into requirements, integration and business change. German buyers often value German-language delivery and local leadership, particularly in highly regulated industries and the Mittelstand. Providers that understand local business practices and decision processes can interpret requirements more accurately and reduce execution friction, ISG says.
"As AI agents move into real delivery workflows, enterprises will need to decide what can be automated and where human accountability must remain," said Oliver Nickels, lead author of the report. "Providers will increasingly need senior professionals who can supervise AI output and translate business requirements into reliable systems."
The report also explores other application trends affecting German enterprises, including AI's effect on traditional effort-based delivery models and growing provider investment in reusable engineering platforms.

The report evaluates the capabilities of 26 providers in one quadrant: Application Development Projects.
It names adesso SE, Allgeier, Coforge, DATAGROUP, Deutsche Telekom MMS, Materna and msg systems as Leaders.
In addition, P3 and Senacor are named as Rising Stars companies with a "promising portfolio" and "high future potential" by ISG's definition in the quadrant.
In the area of customer experience, Altimetrik is named the global ISG CX Star Performer for 2026 among AI-driven ADM service providers. Altimetrik earned the highest customer satisfaction scores in ISG's Voice of the Customer survey, part of the ISG Star of Excellence program, the premier quality recognition for the technology and business services industry.
