IT Landscape Analysis
Know what you actually have before deciding what to change — a rigorous, independent inventory of your full IT landscape.
Understanding This Service
What We Inventory
We produce a comprehensive, validated inventory of your application portfolio, infrastructure, integration landscape, and data flows — capturing what actually exists, not what documentation says should exist.
ArchiMate Structured Documentation
Landscape findings are documented using ArchiMate notation where appropriate, creating structured, reusable architecture artefacts rather than narrative-only reports.
Technical Debt Quantification
We identify and quantify technical debt across the landscape — obsolete systems, unsupported platforms, redundant applications, and integration complexity — so remediation costs can be planned and prioritised.
Why Clients Request This Service
No accurate, current inventory of applications and infrastructure
Integration dependencies are undocumented or unknown
Technical debt is unquantified and invisible to leadership
Architecture decisions are made on incomplete information
Scope of Testing
Our IT Landscape Analysis covers:
Application Portfolio Inventory
Validated inventory of all applications including vendor, version, lifecycle status, business owner, and user base.
Infrastructure Inventory
Documentation of servers, network components, cloud resources, and hosting arrangements with lifecycle and support status.
Integration Mapping
Mapping of all significant system integrations, data flows, and API dependencies across the application landscape.
Technical Debt Assessment
Identification and classification of technical debt — obsolete systems, unsupported platforms, redundant applications, and integration complexity.
Landscape Report and Heat Map
Comprehensive landscape report with application heat map showing lifecycle status, strategic value, and technical debt concentration.
How We Run This Engagement
Scoping
Define landscape boundaries, data collection approach, and key stakeholders for interviews and data gathering.
Data Collection
Stakeholder interviews, documentation review, system discovery, and configuration data collection across defined scope.
Integration Analysis
Mapping of integration dependencies, data flows, and API connections across the application and infrastructure landscape.
Technical Debt Analysis
Classification of technical debt by type, severity, and business impact with remediation effort estimation.
Reporting
Landscape catalogue, integration map, technical debt register, and executive heat map delivered with structured findings.
What You Walk Away With
Application Portfolio Catalogue
Validated inventory of all applications with lifecycle status, ownership, technical characteristics, and strategic classification.
Infrastructure Inventory
Documented inventory of infrastructure components with lifecycle, support status, and hosting arrangements.
Integration and Dependency Map
Visual and documented map of significant system integrations, data flows, and critical dependencies.
Technical Debt Register
Classified register of technical debt items with severity, business impact, and remediation effort estimates.
Application Heat Map
Visual heat map of the application portfolio showing strategic value, technical health, and investment priority.

What Makes Our Testing Different
IT Landscape Analysis from Portamus gives your organisation the factual, validated inventory of your application portfolio, infrastructure, and integration dependencies that architecture decisions require. Rather than working from outdated documentation, we verify what actually exists, map integration complexity, and quantify technical debt — producing structured ArchiMate-notated artefacts and an executive heat map that makes investment priorities visible. This engagement is the essential starting point for application rationalisation, platform modernisation, and digital transformation programmes.
