Legacy Modernization Assurance

We qualify your software landscape architecture, create your risk-based modernization roadmap to ensure your software is fit for business purposes.

Choose the data-driven path to legacy modernization. 

SIG Legacy Modernization Assurance takes a fact-first approach to assess architectural composition, current system build quality, data stores, and active knowledge of development teams.

Powered by our proprietary architecture quality model, SIG assures modernization for landscapes of any size, breaking down complex legacy architectures, and translates these facts into risk-based scenarios for modernization. 

SIG Legacy Modernization Assurance comprises three phases:

SIG Modernization Assurance

Phase 1: Priority Portfolio Scan

We conduct a risk-based scan of your entire portfolio to determine the systems most in need of modernization and prioritize them for update.

Risk-based system prioritization

Systems are prioritized for migration to a new technology, based on the modernization readiness score as well as your current and future business needs.

Modernization readiness score

Each system is scored using the SIG software quality benchmark, derived from the world's largest software analysis database containing 40 billion lines of code across 280+ technologies.

Phase 2: Modernization Assessment

We dive deep into the core of legacy applications to measure quality and risk, translating our findings into a risk-based roadmap to your target state.

Modernization scenarios & custom roadmap

We advise on the best scenario for each component - determining which to rebuild, refactor, or re-platform - and estimate cost, effort and time for each. Your custom modernization roadmap includes an inventory of the most critical risks and prioritized recommendations, avoiding common renovation pitfalls.

Modernization risks identified & measured

We employ our architecture quality model to measure the key aspects that influence modernization roadmaps: architecture quality, code quality, code version history, and data complexity.

Map of implemented architecture

A complete visualization of your implemented software structure is created, pinpointing where important business domains reside, the dependencies between them, and how they interact with the databases.

Restored critical knowledge

The SIG overview of software architecture enables an accurate understanding of complex existing systems, filling critical knowledge gaps within the organization.

Phase 3: Sigrid Continuous Assurance

We ensure your progress to a foundation for future innovation, monitoring and guiding the build with our intelligent technology and human expertise.

Continuous improvement tracking with Sigrid

Sigrid, the SIG software assurance platform, continuously monitors your modernization roadmap, displaying progress made, code quality changes, and areas for improvement. Sigrid code analysis is based on ISO 25010, the international standard for software quality.

Reduced modernization risk

With clear navigation around common transformation pitfalls and continuous guidance powered by the Sigrid platform and SIG experts, we lead your program to a favorable outcome.

Human expertise

Our expert consultants support your team in making critical design decisions, tracking your progress to the future state, and continually updating the roadmap to account for any deviations.

A single source of truth

Sigrid ensures that all organizational stakeholders are using the same data to collaborate and make decisions, leading to favorable migration outcomes.
