Guarantee the performance, security and evolution of your applications over the long term

Once in production, an application requires continuous monitoring to ensure it remains high-performance, secure and adapted to business needs. Without proactive maintenance, software degrades, accumulates vulnerabilities and becomes costly to operate. Third-party application maintenance (TMA) ensures the long-term viability of your solutions, while freeing up your in-house teams.

At IT Systèmes, we take care of the corrective, evolutionary and preventive maintenance of your applications, with a strong commitment to quality, security and responsiveness. Our approach combines supervision, automation and continuous improvement, to guarantee a service that is always aligned with your strategic challenges.

Our TMA (third-party application maintenance) expertise

Corrective maintenance

We quickly correct blocking or disruptive anomalies to ensure business continuity. Our teams intervene according to criticality, with defined SLAs to guarantee short resolution times.

Preventive maintenance

We anticipate incidents by monitoring your applications, applying security patches and updating technical dependencies. This approach reduces downtime and extends software life.

Upgradeable maintenance

We evolve your applications to meet new business needs, regulatory changes (e.g. RGPD, taxation) and technological developments. This allows you to adapt your software without starting from scratch.

Supervision and monitoring

We set up centralized supervision with alerts, dashboards and KPIs to monitor the health of your applications. This visibility enables you to detect and correct problems before they impact your users.

Integration of automation and DevOps

We use automation (scripts, Power Automate, FlexFlow) and DevOps best practices (CI/CD, automated testing) to accelerate incident correction, make updates more reliable and reduce costs.

User support and skills transfer

We support your teams via tickets, hotline or training, and transfer the necessary skills so that your employees can make the most of your applications.

Why work with IT Systèmes?

  • Reduce the risk of service interruption.
  • Guarantee the security and compliance of your applications.
  • Ensure responsive, accessible support for your users.
  • Control maintenance costs through automation.
  • Keep your software up to date with changing needs and regulations.

FAQ TMA (third-party application maintenance)

What is TAM, and how does it differ from outsourcing?

TMA (Third-Party Application Maintenance) focuses exclusively on your applications: fixing, upgrading and optimizing them. Outsourcing, on the other hand, covers the entire infrastructure (servers, networks, workstations). TMA is therefore complementary and dedicated to the long-term future and evolution of your software.

What types of maintenance do you provide for TMA?

We cover three areas: corrective maintenance (troubleshooting), preventive maintenance (patches, updates, supervision) and evolutionary maintenance (new functionalities, regulatory or technical adaptations). This ensures that your application remains high-performance, secure and adapted to your business needs.

How do you guarantee rapid incident resolution?

We define clear SLAs, adapted to the criticality of incidents (blocking, major, minor). Thanks to our monitoring and alerting tools, we detect problems before they impact your users. We mobilize our HNO teams (evenings and weekends) if necessary to guarantee continuity of service.

What is the added value of automation in TMA?

Automation, via FlexFlow and Power Automate, enables recurring incidents to be dealt with rapidly, updates to be made more reliable and processing times to be reduced. For example, a patch or security update can be applied automatically as soon as it is released. This reduces maintenance costs and improves service quality.

How do you support business teams in application maintenance?

We offer accessible support (tickets, hotline, training), clear documentation and skills transfer. Our aim is to ensure that your teams can understand new developments, use new functionalities and benefit from your modernized applications without excessive dependency.

What concrete benefits can my company expect from TMA?

With TMA, you get applications that are more stable, more secure and always adapted to changes in your business. You reduce your operating costs, lower the risk of service interruptions and benefit from complete visibility thanks to monitoring reports. At the same time, your teams can focus on innovation and value creation, rather than on day-to-day incident management.
