Now that FIQ AI has launched, my latest newsletter shares a deeper look at the science behind our platform and how it helps professionals close the gap between how they intend to communicate and how they’re actually perceived. From facial micro-expressions and vocal analysis to our 4Cs Framework (Calm, Clear, Concise, and Confident), this article explores how data-driven insights can help leaders strengthen executive presence, build trust, and communicate with greater impact.

What if you could listen to every customer interaction—at scale? For years, contact center leaders have struggled with limited visibility. Most QA teams review only 2-5% of calls, leaving critical insights buried in recordings that never see the light of day. AI-powered Conversation Intelligence changes that. Instead of relying on outdated keyword spotting or manually scoring a fraction of interactions, AI can analyze 100% of your customer conversations, extracting call drivers, sentiment trends, and agent performance insights in real time. Imagine what you could do with that level of clarity. Identify trends before they become problems—spot surges in customer complaints and act before they escalate. Coach agents with precision—understand exactly where improvements are needed, without listening to hours of calls. Optimize automation strategies—pinpoint high-volume, repetitive workflows that are ripe for AI-driven automation. When every conversation becomes a source of insight, your contact center stops flying blind and starts making proactive, data-driven decisions. How would that change your CX strategy?

Conversation analytics. This is my top pick for investment in #AI and #CX right now. Why? Because it holds the keys to improving everything--employee performance, customer satisfaction, company performance, revenue, employee satisfaction, turnover rates, cost reduction, KPIs, and more. Generative AI has made it possible to dig into every conversation at a company. Sales calls, customer service calls, internal meetings. Take your pick. And, conversation analytics gives you all this information at scale, in near real-time. The exciting part is we are just scratching the surface of its value. Sure, it helps in the #contactcenter, but it also should be used in company-wide, strategic decision-making. What insights could be more valuable than those coming directly from customers? More than 90% of IT/CX/business unit leaders say the data contained in these conversations is THE most valuable or AMONG the most valuable data in the company. One concern, though, is that only about 69% of companies who gather this information are actually acting on it. It should be 100%. Are you gathering conversation analytics? Are you acting on it? What value have you seen with it so far? Most CX providers are delving into this area; for others, it's their entire business. Just to name a few on the CX platform side: 8x8, Amazon Web Services (AWS), Calabrio, Inc., Webex, Five9, NICE, RingCentral, Verint, Zoom. Then there are also specialty providers, such as Cresta, Level AI, Observe.AI,Spearfish, Symbl.ai. Conversation analytics (or interaction analytics) is a big area of focus for Metrigy this year.

Leaders paid attention. Budgets got approved. I had a stronger voice in decision-making. IC pros: If you’re not tracking your impact, you’re leaving influence on the table. What’s one IC metric you swear by? Drop it below! 👇🏽 #DataDrivenComms #InternalCommunications #ROI #Leadership #CommsStrategy

Mosquitto is a free, lightweight, open source broker maintained by the Eclipse Foundation. It’s a great tool for learning about and testing MQTT communication in an #IoT network. My latest video covers installing and configuring the Mosquitto MQTT broker, including how to secure it using SSL/TLS. MQTT is widely used in IoT because it provides a lightweight publish/subscribe model that works well on embedded devices, but it’s important to remember that the protocol itself isn’t encrypted. In the tutorial, I walk through setting up Mosquitto with username/password authentication, generating a private certificate authority, signing a server certificate, and enabling secure communications. I also go over some best practices, such as proper key permissions, why self-signed certificates are only suitable for testing, and when you should switch to a trusted certificate authority like Let’s Encrypt. I finish by demonstrating how to validate the setup using both command-line tools and the MQTTX client. For anyone working with IoT devices, embedded systems, or self-hosted infrastructure, this provides a straightforward overview of how to stand up a secure MQTT broker and test it end-to-end.

Hands-on learning is the cornerstone of mastering IoT/IIoT technologies. A few years ago, I dove headfirst into building a home lab focused on MQTT protocols, time series databases, and container management. What started as curiosity has become an incredible learning adventure that has great crossover to IioT My Current Setup A Synology NAS is at the center with containerized applications and a VM. This lab has become a testing ground to put reading into reality: Home Assistant serves as my central automation and visualization platform... I think of it as a lightweight SCADA system for understanding data flow, dashboard creation, and device orchestration. Mosquitto MQTT Broker acts as the communication backbone. While Home Assistant offers direct integrations, implementing MQTT has deepened my understanding of pub/sub architectures critical in smart manufacturing environments. Zigbee2MQTT interfaces with my Zigbee gateway, connecting wireless mesh to the rest of the system using MQTT SDN (Software Defined Networking)with Omada management platform, PoE switches, and enterprise access points provided hands-on experience with software-defined networking concepts increasingly important in smart manufacturing (I hope). Key Learnings with Industrial Applications: * Data architecture fundamentals that scale from home automation to factory floors * Container orchestration skills applicable to edge computing deployments * Network segmentation principles simular to OT/IT convergence * Real-time data visualization and dashboard design * Time series data Why This Matters for Industry 4.0: These technologies, MQTT messaging, containerized applications, wireless mesh networks, and centralized monitoring are the same/similar to what is used in the industrial world for IIoT The best part, it didn't require a major investment (Although the $$ did grow as I got deeper and deeper) To get started, you don't need a factory or a massive budget to begin learning. A Raspberry Pi, small PC, or NAS can run most of these platforms. Many software solutions are free for educational/home use, and devices like Shelly are cost-effective and are an excellent entry point into local IoT networking. What unconventional learning projects have enhanced your industrial automation skills? Anyone else building out home labs to bridge the gap between consumer IoT and industrial applications?
