Modern Data Reliability in the Age of AI: Why Trust by Design Has Become Non-Negotiable
AI gets the headlines. Data determines outcomes. That was the core argument Sanjeev Mohan made at Signals, Sifflet's reliability conference, hosted by Salma Bakouk. As barriers to data access drop and business users can query data directly without SQL, any underlying weakness propagates faster and hits harder. When AI learns from flawed data, the impact is immediate and exponential. Reliability stops being a technical hygiene topic and becomes a trust problem.
From detection to decision
Many organizations have quietly lived with inconsistent metrics and messy pipelines for years. The cost was manageable: slower decisions, friction between teams. AI changes that tolerance. Sanjeev described what he sees in first meetings with prospects: internal trust has eroded completely. Data teams feel like the last to know and first to be blamed. That dynamic does not just create unpleasant team dynamics; it prevents the business from knowing where to look. Incident response optimization and analytics trust and reliability are no longer optional improvements. They are operational leverage.
Why context-aware observability is the missing piece
Schema-level contracts and traditional monitoring help, but they fall short when teams cannot connect a broken table to a business outcome. A late table is not just a late table. What matters is which KPI it affects, which operation it supports, and how much revenue it touches. Without that context, data quality monitoring becomes impossible to prioritize at scale. The answer is business-aware observability: enriching every anomaly with lineage, ownership, and downstream BI impact so engineers know exactly what to fix first, and why.
Ownership is everyone's problem
Sanjeev was direct: nobody actually owns trust. Engineering owns pipelines. Platforms own infrastructure. Business owns KPIs. Governance writes policies. Trust was expected to emerge naturally from that combination. It rarely does. Making data quality everyone's business requires meeting each persona where they already work: CI/CD for engineers, natural language interfaces for analysts, dashboards for business users. A cross-functional approach built for data leaders, data engineers, data users, and governance teams alike.
Metadata as the glue
As compute disaggregates into multiple engines working against open table formats, a strong metadata layer becomes the substrate that holds everything together. It maintains lineage across disparate systems, applies policies consistently, handles schema evolution, and supports downstream use cases from data integration to feature engineering. Without it, a unified view of quality is impossible.
ROI becomes defensible when context is real
Common operational metrics like mean time to resolution often fail to resonate with finance because they lack business context. Contextual observability changes that: detecting an incident tied to a critical business process before it cascades downstream, preventing a wrong dashboard from reaching a product team before a key decision, avoiding incorrect regulatory reporting that could trigger fines. When monitoring is tied to business criticality, prioritization becomes confident and ROI arguments hold up. The Data Observability Buyer's Guide explores exactly this kind of framework in detail.
The agentic future raises the stakes further
Every software vendor in the data space is introducing agents. That autonomy creates new trust questions: can an ETL agent be trusted to build pipelines? Must observability be built into the agent itself, or does something need to watch what agents do? Sanjeev's conclusion was consistent throughout: trust has to be omnipresent and by design. If autonomous AI agents are not fed reliable data, they can corrupt an entire downstream workflow. Reliability does not become less important as systems become more autonomous. It becomes more central.
