Quality Engineering & AI Evaluation Services - IGS Global

Frequently Asked Questions

What does IGS Global do?

IGS Global is a specialist quality engineering and AI evaluation company founded in 2016. We help organisations build, release, and run digital products with confidence, guiding 1,700+ production releases across OTT, BFSI, Healthcare, and Enterprise SaaS with an 8.8/10 sponsor satisfaction score.

What is AI Evaluation testing, and why does it matter?

AI Evaluation is the systematic process of assessing how well an AI model performs - measuring accuracy, robustness, fairness, and risk across real-world scenarios. Unlike traditional software, AI models can drift, hallucinate, or behave inconsistently under edge cases. At IGS Global, our AI Evaluation service goes beyond benchmark scores. We design adversarial test suites, fairness audits, and confidence calibration checks so you can release AI-powered features with the same certainty you'd expect from any production release.

How is testing an AI model different from testing traditional software?

Traditional software has deterministic outputs - given input A, you always get output B. AI models are probabilistic, meaning the same input can yield different outputs depending on context, temperature, or model version. This means standard pass/fail test cases are not sufficient. AI testing requires distributional evaluation (testing across thousands of inputs), behavioural consistency checks, bias and fairness analysis, and ongoing monitoring post-deployment. IGS Global's Gen 2.0 AI Assist Framework is purpose-built for exactly this challenge.

What types of QA testing does IGS Global provide?

IGS Global covers the full testing spectrum: functional testing, integration testing, regression testing, performance and load testing, UAT (user acceptance testing), exploratory testing, and release validation. We also offer specialised testing for OTT streaming, healthcare systems, banking platforms, and enterprise SaaS. Our testing is not siloed - it's embedded into your SDLC through a shift-left approach, catching defects earlier where they're cheapest to fix. On average, our clients see a 57% reduction in UAT defects within the first engagement cycle.

How quickly can IGS Global increase our test automation coverage?

Our AI-driven automation frameworks are designed for rapid deployment. Most clients achieve a 60% increase in automation coverage within 90 days using our QualiZen platform, which combines intelligent test generation with self-healing capabilities that adapt to UI changes automatically. The exact timeline depends on your codebase maturity, existing test assets, and technology stack - but we always begin with a rapid assessment to give you a concrete coverage roadmap in week one.

What does a 'shift-left' quality engineering approach mean in practice?

Shift-left means embedding quality thinking from the very start of the development lifecycle - during requirements, design, and architecture - rather than treating it as a gate at the end of a sprint. Defects found in production cost up to 100x more to fix than those caught in requirements. In practice this means our QE engineers participate in story refinement, write acceptance criteria, build test harnesses alongside feature code, and provide continuous feedback loops rather than waiting for a handoff. The result: faster releases with fewer surprises.

What industries and platforms does IGS Global specialise in?

IGS Global has deep domain expertise across OTT and streaming media (including clients like AMC Networks and JioHotstar), healthcare and digital health platforms, banking and fintech, enterprise SaaS, and e-learning. We've supported over 150 products and platforms across 14 client locations globally. Domain expertise matters in quality - a QE team that understands OTT video pipelines or healthcare compliance (HIPAA, HL7) writes meaningfully better tests than a generalist team would.

What engagement models does IGS Global offer?

We offer four flexible models: Managed Squads (autonomous QE squads owning delivery risk), TaaS / Flex Capacity (scalable capacity for releases), Outcome-Based (contracts tied to measurable metrics like defect removal efficiency), and Staff Augmentation (embedded specialists backed by IGS leadership and IP). Most clients start with a discovery engagement to identify the best fit before committing to a model.

How does IGS Global measure and report quality outcomes?

We believe quality should be quantified. Every engagement is tracked against agreed KPIs - typically including defect escape rate, automation coverage percentage, regression cycle duration, and UAT defect density. Our AssesQ platform provides organisations with a continuous quality maturity score benchmarked against industry standards. Sponsors receive regular quality dashboards and quarterly business reviews.

What is QualiZen, and how is it different from other test automation tools?

QualiZen is IGS Global's proprietary AI-powered test automation platform. Unlike conventional tools that require manual test script maintenance, QualiZen uses self-healing test capabilities - automatically adapting tests when elements shift. It also includes intelligent test generation from user stories, predictive analytics to identify high-risk areas, and CI/CD integration out of the box.
