EPC Group's Tenant AI Readiness standard, TAR-8 is now featured on G2's TechBlend. The eight-surface score, identity, data, content, Teams, Power BI, CRM, Azure

HOUSTON, TX, UNITED STATES, October 9, 2026 /EINPresswire.com/ -- EPC Group, a Houston-based Microsoft consulting firm founded in 1997, today announced that its Tenant AI Readiness standard, TAR-8, has been added to G2's TechBlend, the technology content hub operated by G2, the business software and services review marketplace. The TechBlend listing at g2.com/techblend links readers to the full standard on epcgroup.net | G2 TechBlend URL: https://www.g2.com/techblend/article/90621/read

TAR-8 scores the eight Microsoft 365 surfaces that AI deployments depend on — identity, data, content, Teams, Power BI, CRM, Azure and ownership — from 0 to 3, with evidence recorded for each score. A tenant's TAR-8 profile tells a buyer, before any license is purchased or any agent is built, which surfaces will carry an AI workload and which will leak data, overspend or stall. The standard is published in full, with its scoring rules and the evidence each score requires, so that any organization can apply it to its own tenant before engaging anyone.

The timing is set by Microsoft's calendar. On October 13, 2026, Office LTSC 2021 reaches end of support and the first year of Windows 10 Extended Security Updates expires. On October 19, 2026, usage-based billing becomes the default for new direct Microsoft 365 Copilot purchases, with a default spending limit of 4,000 Copilot Credits per user per month, and on December 1 for purchases through Cloud Solution Provider partners. Both dates favor tenants that know their readiness surface by surface, and both are hard on tenants that discover it in an invoice.

EPC Group's published guidance on each — a three-week triage plan for the October 13 deadline and a twelve-step spending-policy playbook for usage-based billing — starts from a TAR-8 read of the tenant.

One standard, several practices. TAR-8 is the entry point for the work EPC Group does across the Microsoft estate rather than a product on its own. Before a tenant-to-tenant migration — including the M&A Day-1 cutovers the firm runs under its five-gate model — the acquiring and acquired tenants are both scored, so the migration plan moves readiness with the data rather than discovering gaps after cutover.

Before a Microsoft Fabric capacity commitment, the data and Power BI surfaces are scored so capacity is sized to governed workloads, and Power BI semantic models are certified before any AI is allowed to answer from them. For Dataverse and Power Platform estates, the CRM and ownership surfaces determine whether Copilot Studio agents grounded in Dataverse can be deployed with an owner, a register entry and an evidence trail. For AI governance programs, the eight scores become the baseline the governance office reports against every month.

TAR-8 is not limited to Microsoft's own models. It covers Microsoft Copilot, agents built in Copilot Studio and Microsoft Fabric, and external models such as Claude, ChatGPT and Perplexity, Gemini and Grok when they reach a tenant through a governed, logged integration layer.

The firm's Multi-AI Governance architecture is built for organizations running more than one model, and its published multi-model work — on Power BI architectures that use several engines, on an AI gateway with vendor portability, and on why a single AI vendor is not enough at enterprise scale — assumes a tenant that has been scored first.

The standard is also the operating baseline for EPC Group's Virtual Chief AI Officer practice. A Virtual Chief AI Officer provides fractional AI leadership. EPC Group's vCAIO practice runs an Agent Governance Office that maintains an agent register, a decision register, a consumption statement and an evidence pack every month, and a board summary every quarter. Each of those artifacts is organized by the same eight surfaces, so a board sees the tenant's readiness and its AI spend on one page.

"Most AI programs do not fail on the model; they fail on the tenant underneath it," said Errin O'Connor, Founder and Chief AI Architect of EPC Group. "We published TAR-8 so that a buyer can see the evidence before they see a proposal, and so that the same eight numbers follow a tenant through a migration, a Fabric decision, an agent rollout and a board review. Being featured on G2's TechBlend puts the standard in front of the people who are comparing firms, which is exactly where a readiness score belongs."

How a buyer can verify EPC Group's claims: read the verified client reviews on G2, open an engagement record in the Evidence Center, read the methodology page, and ask for a redacted sample of the deliverable being proposed. EPC Group has been named a Leader in seven G2 reports; that history is published as text on the firm's site and is not the basis of the TechBlend listing, which links to the standard itself.

Organizations that want TAR-8 applied to their own tenant can request a scoping conversation through the readiness-assessment page or the contact page linked below.
