This legacy risk assessment creates an initial shared view of an established application. Answer for the system as it operates today, not for planned improvements. The private result stays on your device and classifies the situation into four practical levels.

Signals that indicate elevated legacy software risk
Legacy software is not automatically poor software. Many long-serving applications contain valuable business rules and operate reliably. Risk appears when necessary change, secure operations, or recovery can no longer be planned with confidence.
Concentrated knowledge is a common warning. If one person alone understands the data model, build process, or exceptional cases, every absence becomes a continuity issue. Written notes are not enough; another person must be able to perform critical procedures in practice.
Unsupported runtimes and libraries also deserve attention. They can block security patches, prevent operating system upgrades, and reduce access to specialist skills. Structured legacy software modernization therefore starts with evidenced dependencies rather than a blanket rewrite decision.
Four perspectives for a dependable assessment
- Knowledge: Are architecture, business rules, ownership, and cover understandable?
- Technology: Are runtimes, frameworks, and external components still supported?
- Operations: Are builds, tests, releases, monitoring, backups, and rollback reproducible?
- Data: Are authoritative sources, interfaces, archives, and recovery resolved?
An overall score must not hide a single critical finding. An untested backup remains urgent even when other areas perform well. Use the result as the start of a review, never as approval for unchanged operation.
Turn a risk picture into controlled modernization
Start with measures that increase room for action. Test recovery, secure access to source code and build tools, document contacts, and create a reproducible application baseline. These steps reduce exposure without immediately rebuilding the business solution.
Next, map frequent changes and incidents. A component with few events but severe outage potential needs different treatment from a module that delays every small requirement. Score business impact, likelihood, dependencies, and feasibility separately before ordering the work.
Some systems benefit from gradual decoupling. Others first need characterization tests around critical business rules. When defects are immediate, focused software rescue and stabilization can create a safe starting point. Only then can teams choose responsibly between upgrades, partial replacement, and redevelopment.
Give every work package a business outcome and fallback. Technical improvements should demonstrably shorten lead times, reduce incidents, make releases safer, or lower dependence on individuals. Modernization then becomes a governable investment rather than an open-ended technology program.

Legacy risk assessment FAQ
What does the legacy risk assessment evaluate?
It examines knowledge concentration, technology lifecycle, changeability, testing, operations, data, and recovery. The result is a structured initial orientation, not a complete software audit.
How is the risk level calculated?
Every answer carries a value from one to four. The average determines the level, while the three weakest topic areas become prioritized recommendations.
Is information about the application stored?
No. Answers and calculations remain locally in the browser. The tool sends no project data, requires no account, and stores no result on a server.
What should happen after the assessment?
Review the result with business, IT, and operations. Contain immediate continuity or knowledge risks first, then build a modernization roadmap with named owners and acceptance criteria.
