Our Work.
At ALT Solutions, we support federal agencies and partners with independent analytics, model validation, and AI assurance in high-impact, highly scrutinized environments. Our work reflects real-world application of rigorous analytical methods to evaluate models, assess risk, and support defensible decision-making.
The case studies below highlight engagements spanning independent model validation and governance, AI test and evaluation, financial and risk analytics, modeling and decision support, and governance-ready reporting. Each example demonstrates our commitment to technical rigor, transparency, and oversight-aligned delivery—helping organizations make decisions they can stand behind.
01
Independent Model Validation & Governance
Context: A federal housing finance program responsible for a multi-billion-dollar insured loan portfolio relied on production credit risk models to support financial reporting, budget formulation, and portfolio oversight. Independent validation was required to ensure model reliability, transparency, and defensibility under regulatory and audit scrutiny.
Approach: ALT Solutions performed independent model validation activities aligned with established model risk management practices. The work included review of model design and assumptions, evaluation of input data and transformations, performance testing across key segments, sensitivity analysis, and assessment of limitations and model use considerations. Validation findings were documented to support governance and ongoing monitoring.
Governance Focus: Validation deliverables were structured to support audit readiness, clear communication of uncertainty, and appropriate use of model outputs in decision-making. ALT operated independently from model development and implementation for the validation scope.
Outcome:The validation strengthened confidence in production model results, improved governance documentation, and supported defensible financial and risk decisions under oversight.

02
Financial & Risk Analytics
Context: A federal credit program managing a large and diverse portfolio required improved understanding of financial exposure and risk across economic conditions to support long-range planning, budget analysis, and stakeholder reporting.
Approach: ALT Solutions applied financial and risk analytics to interpret portfolio-level model outputs, assess exposure under alternative scenarios, and evaluate sensitivity to key economic drivers. The analysis focused on translating complex model results into clear, decision-relevant risk insights aligned with oversight and reporting needs.
Governance Focus: The work emphasized transparency, traceability of assumptions, and consistency with governance expectations for federal financial programs.
Outcome: The analysis enhanced leadership’s ability to understand material risk drivers, communicate exposure clearly, and support informed financial planning under uncertainty.

03
Modeling & Decision Support
Context: A federal financial program relied on complex forecasting and cash-flow models to evaluate long-term portfolio sustainability and inform policy and program decisions under varying economic conditions.
Approach: ALT Solutions supported modeling and scenario analysis to evaluate sensitivities, alternative assumptions, and potential outcomes across economic environments. The work focused on understanding trade-offs, uncertainty, and key drivers affecting portfolio performance.
Governance Focus: Modeling outputs were structured to support clear interpretation, documentation of assumptions, and appropriate use in decision-making contexts.
Outcome: The analysis improved clarity around potential outcomes and risks, supporting informed planning and program decisions grounded in defensible analytical evidence.

04
Challenger Model Development
Context: A federal credit program required independent benchmarking of production risk models to support validation conclusions and strengthen model governance.
Approach: ALT Solutions developed challenger models using alternative methodologies, variable specifications, and segmentation strategies to independently assess production model behavior. The work included exploratory data analysis, feature evaluation, comparative performance testing, and sensitivity analysis to assess robustness and interpretability across portfolio segments.
Governance Focus: Challenger models were explicitly designed to support validation and governance objectives, including documentation of limitations, model use considerations, and comparison of key risk drivers.
Outcome: The challenger analysis provided an objective reference point for evaluating production model performance, strengthened governance documentation, and supported defensible validation conclusions under audit and oversight.
