| Stage-aging rule (deterministic) | Flag when stage duration crosses calibrated threshold; HubSpot default is 20% above owner closed-won average for that stage. | Teams need transparent alert logic and can keep stage definitions stable. | Owner baselines with sparse history can over-flag enterprise motions or under-flag outlier segments. | HubSpot deal properties 2026-01-11 |
| Activity-aging rule | Flag deals after configured inactivity days from the last meaningful deal activity. | Teams need lightweight stagnation surveillance without ML infrastructure. | Hidden activities can reset rotting timers, and future activities can prevent a deal from rotting. | Pipedrive rotting feature 2026-04-15 |
| Predictive opportunity scoring (ML) | Build scores from historical won/lost patterns with minimum 40 won + 40 lost opportunities across two years. | Teams have enough closed-history volume, stable labels, and data governance resources. | Cold-start teams cannot initialize robust models; monthly scoring capacity can constrain broad experiments. | Dynamics 365 lead and opportunity scoring 2026-02-27 |
| Predictive refresh cadence boundary | Opportunity score updates use no more than the previous 24 hours of changes and do not support instant same-hour recalculation. | Teams run daily or weekly intervention cycles, not minute-level rescue workflows. | If your process requires intraday rescue reactions, score refresh cadence can lag operational needs. | Dynamics 365 prioritize opportunities 2025-08-21 |
| Regulatory boundary (EU AI Act) | Risk obligations depend on deployment context and risk tier; prohibited practices and high-risk obligations follow staged deadlines. | Cross-region rollout needs policy alignment before expansion into adjacent use-cases. | A workflow that starts as low-risk can move into high-risk duties when repurposed for regulated decisions. | European Commission AI Act framework Reviewed 2026-04-23 |
| Solely automated decision boundary (UK GDPR/ICO) | Restrictions apply when decisions are solely automated and produce legal or similarly significant effects on individuals. | Teams keep meaningful human review and a documented challenge path for affected individuals. | If human review is superficial, organizations can still face automated-decisioning compliance risk. | ICO guidance on automated decision-making and profiling Under review note dated 2025-06-19 |
