L2/L3 application support

We keep applications useful, stable and maintainable after launch.

We take over existing applications or products delivered by us and organize technical support around incidents, recurring causes, upgrades and changes with controlled risk.

Suitable situations

Support starts by understanding the system, not by selling a generic retainer.

We define components, dependencies, environments, access and operational impact before agreeing response targets or responsibilities.

Incidents

Errors affect users

We triage, reproduce and fix issues while keeping a technical history of decisions.

Takeover

The original supplier is unavailable

We audit code, infrastructure and documentation before accepting operational responsibility.

Maintenance

Dependencies and platforms are ageing

We plan updates and tests so that risk remains visible and controlled.

Evolution

Continuous changes are required

We separate incidents from development requests and prioritize a shared backlog.

Coverage

Operational support and technical maintenance across the application lifecycle.

The exact model depends on business criticality, technology, source access and the required coverage window.

  • technical inventory, application health assessment and takeover plan;
  • L2/L3 incident management and root-cause analysis;
  • monitoring, logs, alerts and availability checks;
  • security remediation and dependency updates;
  • corrective, preventive and adaptive maintenance;
  • change requests and incremental development;
  • technical documentation and intervention history;
  • SLA and reporting aligned with actual application impact.

Delivery process

A clear technical process with reviewable decisions and deliverables.

Stages are adapted to product maturity, risk and objectives without adding unnecessary complexity.

01

Discovery

We inventory code, infrastructure, integrations, known incidents and available access.

02

Definition

We define severity, ownership, channels, support windows and acceptance criteria.

03

Implementation

We introduce monitoring, address urgent risks and gradually take ownership of the request flow.

04

Validation and support

We report interventions, track recurrence and adjust priorities based on impact.

FAQ

Frequently asked questions

Can you take over an application built by another supplier?

Yes, when the audit confirms sufficient access to code, infrastructure and data. We begin with a takeover phase instead of promising an SLA before assessment.

What does L2/L3 support mean?

L2 covers technical analysis and known issue resolution, while L3 involves code, architecture or integration changes. The exact boundary is documented for each application.

Do you provide 24/7 support?

Coverage is agreed according to criticality and required capacity. We do not present 24/7 as the default model for every application.

Does support include new development?

It can, but incidents and maintenance are separated from change requests so priorities, estimates and costs remain transparent.

How does a support engagement start?

With a technical inventory, controlled access, a risk list and a transition period that validates the working model.
