HEVD is part of Røkte, TvimenningOld Norse meaning 'two bound together' - one who solves a task shoulder to shoulder with another.'s operations family, and delivers data qualityThe degree of accuracy, completeness and reliability in a dataset - critical for correct billing and balance settlement in the power sector. and data cleansingCorrecting errors in data that already exists - duplicates, gaps, misspellings and inconsistent formats - most often in master data and most often after the fact. as an ongoing managed service - not a one-off project. The name comes from Old Norse hefð, "custom, practice, usage", and lives on in Norwegian law today: hevd is the legal doctrine of acquiring a right - typically to property or a right of use - through long-term, continuous and uncontested use, today governed by the Norwegian Prescription Act (hevdsloven). The legal point is precise: the right does not arise once and for all. Use must continue, without interruption, for the claim to hold - break it, and the right disappears. In farming society, the same principle produced good harvests: land held i hevd yielded results because someone tended it continuously. HEVD applies exactly this double meaning to data: data quality is not something you achieve once and are done with, it is something you must keep i hevd, on an ongoing basis. The service has two phases: first an onboardingStructured startup and integration - either of new developers to a project or of a new vendor with accompanying knowledge transfer. phase where the data foundation is mapped, quality is analysed and root causes are corrected - then ongoing operations where data quality is monitored continuously, deviations are caught early, and someone concrete owns the follow-up. HEVD is not limited to Tvimenning's own products: the service covers third-party systems such as KISCustomer Information System - the core system at power suppliers and grid companies for customer management and billing., NIS, ERPEnterprise Resource Planning - business system integrating finance, HR, logistics and operations., SCADASupervisory Control and Data Acquisition - system for real-time monitoring and control of industrial processes. and CRMCustomer Relationship Management system for managing customer relations, sales processes and support tasks. just as much, since data quality problems cross system boundaries.
