Methodology

Support engagements begin with application discovery, documentation review and knowledge transfer. We establish support processes, monitoring, incident classification, escalation paths and reporting. Modernisation follows an assess, plan, execute and validate cycle.

Competence

Our application support engineers have experience across enterprise application stacks, databases, middleware and integration platforms. Modernisation assessments are conducted by architects with migration experience.

Governance & Quality

Support is governed through defined SLAs, incident management processes, change control, problem management and regular service reviews. Every support engagement has a named service manager.

Frequently Asked Questions

What is the difference between L2 and L3 support?

L2 support handles complex incidents requiring application knowledge and configuration. L3 support involves deep technical investigation, code level diagnosis and specialist engineering resolution.

Can you modernise legacy applications without full rewrite?

Yes. We assess each application and recommend the appropriate strategy, from incremental refactoring and API wrapping to selective re platforming, based on business value and technical risk.

How do you handle support transitions?

Transitions follow a structured knowledge transfer process: documentation review, shadowing, parallel running and phased handover with acceptance criteria.
