Enterprise Delivery OS

Reference Models. Operating Playbooks. Runbooks & Controls.

Tech-agnostic, enterprise-grade
Controls + Evidence built-in
KPIs & SLOs, not opinions

What this is

This library helps teams build and operate digital systems with predictable outcomes: growth, reliability, and trust.

Each topic is structured as a model (what good looks like), a playbook (how to implement), and a runbook (how to operate safely).

How to navigate

Use Start Here to choose your problem and maturity level.
Use Reference Models to design capabilities and controls.
Use Playbooks to execute change safely.
Use Runbooks when the risk is high and time matters.

Ollama Is Not the Product: Building Production-Ready Open-LLM Applications

Running a local model with Ollama is easy. Building a production-ready Open-LLM application is harder: it requires RAG, access control, provider abstraction, evaluation, logging, deployment discipline and a controlled application layer around the model.

The Next OpenWrt 5G Router: Why Wi-Fi 7, a Stronger CPU and Better Firmware Matter

The ZBT Z8102AX is a useful first sample, but the next step should be stronger: Wi-Fi 7, a more powerful four-core platform, better firmware clarity, improved packaging and a more stable pricing policy. The goal is not just another 5G router, but a better configured OpenWrt-based prosumer device.

Should You Buy a 5G OpenWrt Router with Old Firmware? ZBT Z8102AX as a Practical Example

Buying a 5G OpenWrt router with older firmware can make sense, but only under the right conditions. The ZBT Z8102AX shows both sides clearly: the hardware is useful, the modem works, and the router stayed stable in testing, but OpenWrt 21.02, weak packaging and unclear upgrade paths require a careful buying decision.

ZBT Z8102AX Dual-SIM Failover: What Works, What Is Missing and What Needs Better Firmware

The ZBT Z8102AX is a dual-SIM 5G OpenWrt router, but dual-SIM hardware alone is not the same as intelligent failover. The router recognizes the SIM and connects successfully, but automatic switching, modem recovery, signal-based decisions and clean failover logic still need deeper testing.

ZBT Z8102AX OpenWrt 21.02 Firmware Review: Stable Enough, but Is It Future-Proof?

The ZBT Z8102AX runs a vendor-modified OpenWrt 21.02 build with kernel 5.4.246. In practical testing, the firmware worked successfully and kept the router stable for several days, but the old base raises important questions about security, modem control, upgrade paths and long-term maintainability.

Quectel RM500U-EA in the ZBT Z8102AX: 5G Bands, o2 Germany and Real-World Signal Behavior

The ZBT Z8102AX uses a Quectel RM500U-EA modem for 4G and 5G connectivity. In the first practical test, the router connected successfully to o2 Germany with LTE Band 3 and NR n28. The modem works, but deeper diagnostics such as RSRP, RSRQ, SINR, band locking and cell behavior still need proper testing.

ZBT Z8102AX Hardware and Packaging Review: Strong Router, Weak Box

The ZBT Z8102AX makes a solid first impression as a slim black metal 5G OpenWrt router with multiple antenna connectors, dual-SIM slots, USB, LAN/WAN ports and a practical accessory set. The hardware feels useful and serious, but the packaging is clearly the weak point.
