Business workflows
Critical journeys, operational deadlines, manual workarounds, exceptions, pain points and accountable owners.
Legacy System Assessment
Turn an ageing system into a practical modernization roadmap.
We assess business-critical workflows, architecture, data, integrations, infrastructure and delivery constraints—then identify immediate risk, sensible modernization options and a phased route forward.
Assessment scope
See the whole operating system, not only the code.
Legacy constraints usually cross product, process, data and infrastructure. We examine the relationships that affect continuity and change.
Application architecture
Components, dependencies, releases, supportability, test coverage and the boundaries available for staged change.
Data & integrations
Systems of record, data quality, access, interfaces, failure handling, migration constraints and reconciliation needs.
Infrastructure & DevOps
Environments, deployment, observability, capacity, backups, recovery, access and material cost signals.
Security & continuity
Unsupported dependencies, permissions, sensitive data, auditability and risks that require immediate control.
Team & delivery model
Knowledge concentration, decision ownership, vendor constraints and the organisation's ability to operate change.
What you receive
A decision package your team can use.
The exact depth follows the system and available evidence. We agree scope before beginning and distinguish verified facts from assumptions that still need testing.
- Current-state findings across workflow, application, data and infrastructure
- Risk map separating urgent controls from longer-term constraints
- Modernization options: stabilise, encapsulate, replatform, replace, buy or retire
- Prioritised roadmap with dependencies, quick wins and phased outcomes
- Migration and coexistence considerations for critical data and integrations
- Implementation outline, assumptions and next-stage estimation inputs
How it works
Evidence before architecture decisions.
We keep the work focused on decisions and continuity rather than producing documentation for its own sake.
Frame
Agree outcomes, critical workflows, constraints, stakeholders and accessible evidence.
Investigate
Review the system, data, integrations, delivery and operating history with responsible teams.
Test options
Compare feasible paths, dependencies, risk, reversibility and the evidence still missing.
Roadmap
Present prioritised actions, phased outcomes and the smallest valuable next investment.
Assessment questions
What teams usually want to know.
Does the assessment always recommend a rewrite?
No. The right next step may be stabilisation, observability, an API boundary, selective refactoring, replatforming, replacement of one capability or retirement. A full rewrite should be an evidence-backed conclusion.
Can you assess a system with limited documentation?
Yes. We combine available documentation with stakeholder sessions, source and architecture review, operational evidence and representative workflows. Missing evidence is recorded as risk rather than guessed.
Will we receive a fixed implementation price?
The assessment creates a stronger basis for estimation. Where scope is sufficiently bounded, the next phase can be estimated as milestones; unresolved data or integration uncertainty may require validation first.
Can implementation be phased around live operations?
That is usually the goal. We identify seams, coexistence requirements, migration controls and rollback needs so change can be sequenced without one high-risk cutover.
Prepare before the call
What is the legacy system preventing your business from doing?
Share the system, critical workflows and current symptoms. We’ll respond with the evidence needed to define an assessment.
