About This Tool

The tool analyzes a set of legacy repositories to reveal modernization opportunities and quantify debt. It interprets repository metrics, language breadth, and test coverage to produce a prioritized modernization plan. It translates complex architectural concerns into actionable tasks and timelines for leadership buy-in. By comparing current and target tech stacks, it highlights high-impact domains, such as composable modules, test automation, and dependency resilience, enabling incremental delivery.
Conceptually, the system ingests project metadata, applies risk weighting to metrics like LOC, module count, and dependency graphs, and outputs a roadmap with task names, priorities, and estimated effort. This helps engineers forecast effort, align stakeholders, and make trade-offs between speed and stability. Beneficiaries include engineering managers, platform teams, and consultants who need data-driven justification for modernization choices. Unique value lies in end-to-end planning artifacts, scenario comparisons, and exportable roadmaps that tie technical debt to business outcomes. Core features include debt quantification, risk scoring, modernization delta estimation, task prioritization, and roadmap generation, with optional repo integration and scenario modeling for what-if analyses.
Use cases cover initial modernization scoping, budget iteration, and governance reviews. Outputs support decision-making by translating technical complexity into concrete milestones and cost estimates, enabling transparent conversations with product, finance, and operations partners.

How to Use

Provide inputs for project_name, languages, LOC, modules, current and target tech stacks, and test coverage.
Choose modernization goals (language upgrade, modularization, testing improvements).
Run analysis to generate risk scores, modernization deltas, and a prioritized task list.
Review the actionable roadmap and export reports for stakeholders.
Iterate scenarios to observe how changes affect risk and timelines.

Frequently Asked Questions

Find Quick Answers

What inputs are required to run the analysis?
Required inputs include project_name, languages, LOC, modules, current_tech_stack, and target_tech_stack. Optional inputs such as current_coverage and allow_external_data can refine results. Sample values provided in the examples help calibrate scores.
What outputs does the tool produce?
The tool outputs a risk_score (0-100), modernization_delta (target minus current metrics), a prioritized list of recommended_tasks with estimates, and a roadmap timeline plus a cost estimate in the chosen currency.
How is the risk score calculated?
Risk score is a weighted composite of LOC, module count, dependency complexity, and coverage gaps. Weights reflect typical debt impact patterns; higher scores indicate greater modernization urgency and risk exposure.
Can I export or share the results?
Yes. The analysis supports export of reports in JSON/CSV formats and sharing of the roadmap with stakeholders, enabling alignment across engineering, product, and finance teams.
