Over the last year, I’ve seen many people fall into the same trap: They launch an AI-powered agent (chatbot, assistant, support tool, etc.)… But only track surface-level KPIs — like response time or number of users. That’s not enough. To create AI systems that actually deliver value, we need 𝗵𝗼𝗹𝗶𝘀𝘁𝗶𝗰, 𝗵𝘂𝗺𝗮𝗻-𝗰𝗲𝗻𝘁𝗿𝗶𝗰 𝗺𝗲𝘁𝗿𝗶𝗰𝘀 that reflect: • User trust • Task success • Business impact • Experience quality    This infographic highlights 15 𝘦𝘴𝘴𝘦𝘯𝘵𝘪𝘢𝘭 dimensions to consider: ↳ 𝗥𝗲𝘀𝗽𝗼𝗻𝘀𝗲 𝗔𝗰𝗰𝘂𝗿𝗮𝗰𝘆 — Are your AI answers actually useful and correct? ↳ 𝗧𝗮𝘀𝗸 𝗖𝗼𝗺𝗽𝗹𝗲𝘁𝗶𝗼𝗻 𝗥𝗮𝘁𝗲 — Can the agent complete full workflows, not just answer trivia? ↳ 𝗟𝗮𝘁𝗲𝗻𝗰𝘆 — Response speed still matters, especially in production. ↳ 𝗨𝘀𝗲𝗿 𝗘𝗻𝗴𝗮𝗴𝗲𝗺𝗲𝗻𝘁 — How often are users returning or interacting meaningfully? ↳ 𝗦𝘂𝗰𝗰𝗲𝘀𝘀 𝗥𝗮𝘁𝗲 — Did the user achieve their goal? This is your north star. ↳ 𝗘𝗿𝗿𝗼𝗿 𝗥𝗮𝘁𝗲 — Irrelevant or wrong responses? That’s friction. ↳ 𝗦𝗲𝘀𝘀𝗶𝗼𝗻 𝗗𝘂𝗿𝗮𝘁𝗶𝗼𝗻 — Longer isn’t always better — it depends on the goal. ↳ 𝗨𝘀𝗲𝗿 𝗥𝗲𝘁𝗲𝗻𝘁𝗶𝗼𝗻 — Are users coming back 𝘢𝘧𝘵𝘦𝘳 the first experience? ↳ 𝗖𝗼𝘀𝘁 𝗽𝗲𝗿 𝗜𝗻𝘁𝗲𝗿𝗮𝗰𝘁𝗶𝗼𝗻 — Especially critical at scale. Budget-wise agents win. ↳ 𝗖𝗼𝗻𝘃𝗲𝗿𝘀𝗮𝘁𝗶𝗼𝗻 𝗗𝗲𝗽𝘁𝗵 — Can the agent handle follow-ups and multi-turn dialogue? ↳ 𝗨𝘀𝗲𝗿 𝗦𝗮𝘁𝗶𝘀𝗳𝗮𝗰𝘁𝗶𝗼𝗻 𝗦𝗰𝗼𝗿𝗲 — Feedback from actual users is gold. ↳ 𝗖𝗼𝗻𝘁𝗲𝘅𝘁𝘂𝗮𝗹 𝗨𝗻𝗱𝗲𝗿𝘀𝘁𝗮𝗻𝗱𝗶𝗻𝗴 — Can your AI 𝘳𝘦𝘮𝘦𝘮𝘣𝘦𝘳 𝘢𝘯𝘥 𝘳𝘦𝘧𝘦𝘳 to earlier inputs? ↳ 𝗦𝗰𝗮𝗹𝗮𝗯𝗶𝗹𝗶𝘁𝘆 — Can it handle volume 𝘸𝘪𝘵𝘩𝘰𝘶𝘵 degrading performance? ↳ 𝗞𝗻𝗼𝘄𝗹𝗲𝗱𝗴𝗲 𝗥𝗲𝘁𝗿𝗶𝗲𝘃𝗮𝗹 𝗘𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝗰𝘆 — This is key for RAG-based agents. ↳ 𝗔𝗱𝗮𝗽𝘁𝗮𝗯𝗶𝗹𝗶𝘁𝘆 𝗦𝗰𝗼𝗿𝗲 — Is your AI learning and improving over time? If you're building or managing AI agents — bookmark this. Whether it's a support bot, GenAI assistant, or a multi-agent system — these are the metrics that will shape real-world success.

📊 What’s the right KPI to measure an AI agent’s performance? Here’s the trap: most companies still measure the wrong thing. They track activity (tasks completed, chats answered) instead of impact. Based on my experience, effective measurement is multi-dimensional. Think of it as six lenses: 1️⃣ Accuracy – Is the agent correct? Response accuracy (right answers) Intent recognition accuracy (did it understand the ask?) 2️⃣ Efficiency – Is it fast and smooth? Response time Task completion rate (fully autonomous vs guided vs human takeover) 3️⃣ Reliability – Is it stable over time? Uptime & availability Error rate 4️⃣ User Experience & Engagement – Do people trust and return? CSAT (outcome + interaction + confidence) Repeat usage rate Friction metrics (repeats, clarifying questions, misunderstandings) 5️⃣ Learning & Adaptability – Does it get better? Improvement over time Adaptation speed to new data/conditions Retraining frequency & impact 6️⃣ Business Outcomes – Does it move the needle? Conversion & revenue impact Cost per interaction & ROI Strategic goal contribution (retention, compliance, expansion) Gartner predicts that by 2027, 60% of business leaders will rely on AI agents to make critical decisions. If that’s true, then measuring them right is existential. So, here’s the debate: Should AI agents be held to the same KPIs as humans (outcomes, growth, value) — or do they need an entirely new framework? 👉 If you had to pick ONE metric tomorrow, what would you measure first? #AI #Agents #KPIs #FutureOfWork #BusinessValue #Productivity #DecisionMaking

CSAT measurement must be more than just a score. Many companies prioritize their Net Promoter Score (NPS) as a measure of Customer Satisfaction (CSAT). But do these methods truly give us a complete understanding? In reality, surveys are not always accurate. Bias can influence the results, ratings may be misinterpreted, and there's a chance that we didn't even ask the right questions. While a basic survey can indicate problems, the true value lies in comprehending the reasons behind those scores and identifying effective solutions to improve them. Here’s a better way to look at CSAT: 1. Start with Actions, Not Just Scores: Observable behaviors like repeat purchases, referrals, and product usage often tell a more accurate story than a survey score alone. 2. Analyze Digital Signals & Employee Feedback: Look for objective measures that consumers are happy with what you offer (website micro-conversions like page depth, time on site, product views and cart adds). And don’t forget your team! Happy employees = Happy customers. 3. Understand the Voice of the Customer (VoC): Utilize AI tools to examine customer feedback, interactions with customer support, and comments on social media platforms in order to stay updated on the current attitudes towards your brand. 4. Make It a Closed Loop: Gathering feedback is only the beginning. Use it to drive change. Your customers need to know you’re listening — and *acting*. Think of your CSAT score as a signal that something happened in your customer relationships. But to truly improve your business, you must pinpoint the reasons behind those scores and use that information to guide improvements. Don’t settle for simply knowing that something happened, find an answer for why it happened.

𝑯𝒐𝒘 𝑻𝒐𝒅𝒂𝒚’𝒔 𝑻𝒐𝒑 𝑪𝒐𝒏𝒔𝒖𝒎𝒆𝒓 𝑩𝒓𝒂𝒏𝒅𝒔 𝑺𝒖𝒄𝒉 𝒂𝒔 𝑵𝒆𝒕𝒇𝒍𝒊𝒙, 𝑨𝒎𝒂𝒛𝒐𝒏, 𝒂𝒏𝒅 𝑨𝒊𝒓𝒃𝒏𝒃 𝑴𝒆𝒂𝒔𝒖𝒓𝒆 𝑴𝒂𝒓𝒌𝒆𝒕𝒊𝒏𝒈’𝒔 𝑰𝒎𝒑𝒂𝒄𝒕 (65+ 𝑪𝒂𝒔𝒆 𝑺𝒕𝒖𝒅𝒊𝒆𝒔) I had a client for whom we simultaneously ran an offline PR campaign and a Facebook marketing campaign. They spent £50k on the former and afterwards, we ran some experiments to test effectiveness. Here are the results: → PR campaign CAC: ~£450 → Facebook CAC: £18 It shows the importance of measuring impact in both traditional marketing and growth hacking. Michael Kaminsky (Co-founder of marketing analytics firm, Recast) and Mike Taylor (founder of training platform, Vexpower) recently guested on Lenny’s Newsletter, explaining how today’s top brands measure marketing attribution and incrementality through 65+ case studies. Links to Lenny’s Newsletter and the database are in the comments. Understanding these 3 techniques will help you avoid the costly mistake made by my client: 🔸 Digital Tracking/Multi-touch Attribution (MTA) Benefits: > Leverage the data you’re accumulating daily > Easy to implement Drawbacks: Attribution can lead to a bun fight over resources when one channel appears better than another. Airbnb reminds us that MTA shows what your customer journey looks like today – indicating the touchpoints for improvement, so you can adjust your marketing mix. 🔸 Marketing Mix Modelling (MMM) Benefits: > Uses aggregated data, so no privacy concerns > Facilitates measurement of offline/traditional marketing campaigns Drawbacks: Historically, MMM is expensive to implement and slow to produce results, but Uber is just one of the companies returning to MMM in light of the impending cookie switch-off and Apple IDFA changes. 🔸 Testing/Conversion Lift Studies (CLS) Benefits: > More accurate measurement than click-through rates > Can be tailored to specific campaigns, making it ideal to measure growth hacking experiments Drawbacks: CLS can be impractical or cost-prohibitive to set up. Geography is quite often the go-to, allowing brands like Netflix to test the impact of their billboard campaigns, for example. I’ve said it before, “no amount of data is enough data”, which is why these measurement techniques should be used in combination. I’m pleased to see that Kaminsky and Taylor and 40% of their sample population are in agreement, including Mcdonald's, who used CLS to validate their MMM model. Measurement is only part of the equation. You need to interpret the results for them to have any utility. I recommend a weekly sprint approach for monitoring experimentation results, which can be adapted to impact measurement: → Review performance against your benchmark/hypothesis → Are the results and benchmarks aligned? If not, why not? → Action any lessons learned and repeat How do you measure impact? 👇 #marketing #growthhacking #impact 

A few weeks ago, I was in a conversation with a VP at a major fintech in India. We were talking about an incident which lead to downtime and impacted few thousands of dollars in a matter of minutes. As we discussed how to handle these situations better, we kept coming back to one question: What’s the story of that incident, and how can data help us uncover it? At DevDynamics, this question is at the core of what we do. Engineering visibility doesnt end at metrics, infact it begins from them to tell the right story, the kind that leads to real solutions. Here is what we came up with. Imagine an outage hits your platform. Everyone’s asking what went wrong. Where do you start? You begin by gathering the pieces of the story: 1️⃣ 𝐓𝐡𝐞 𝐎𝐩𝐞𝐧𝐢𝐧𝐠 𝐂𝐡𝐚𝐩𝐭𝐞𝐫: 𝐇𝐨𝐰 𝐐𝐮𝐢𝐜𝐤𝐥𝐲 𝐃𝐢𝐝 𝐖𝐞 𝐀𝐜𝐭? - 𝐌𝐞𝐚𝐧 𝐓𝐢𝐦𝐞 𝐭𝐨 𝐑𝐞𝐜𝐨𝐯𝐞𝐫𝐲 (𝐌𝐓𝐓𝐑): This tells how fast your team resolved the issue. If it took too long, what slowed you down? - 𝐓𝐢𝐦𝐞 𝐭𝐨 𝐃𝐞𝐭𝐞𝐜𝐭 (𝐓𝐓𝐃): Did you spot the problem quickly, or was there a gap in monitoring? 2️⃣ 𝐓𝐡𝐞 𝐂𝐨𝐧𝐟𝐥𝐢𝐜𝐭: 𝐖𝐡𝐚𝐭 𝐂𝐚𝐮𝐬𝐞𝐝 𝐭𝐡𝐞 𝐈𝐧𝐜𝐢𝐝𝐞𝐧𝐭? - 𝐂𝐡𝐚𝐧𝐠𝐞 𝐅𝐚𝐢𝐥𝐮𝐫𝐞 𝐑𝐚𝐭𝐞 (𝐂𝐅𝐑): Was this the result of a bad deployment? - 𝐂𝐨𝐝𝐞 𝐐𝐮𝐚𝐥𝐢𝐭𝐲 𝐌𝐞𝐭𝐫𝐢𝐜𝐬: Were there bugs, vulnerabilities, or technical debt that contributed to the failure? 3️⃣ 𝐓𝐡𝐞 𝐏𝐚𝐭𝐭𝐞𝐫𝐧𝐬: 𝐈𝐬 𝐓𝐡𝐢𝐬 𝐏𝐚𝐫𝐭 𝐨𝐟 𝐚 𝐁𝐢𝐠𝐠𝐞𝐫 𝐏𝐥𝐨𝐭? - 𝐃𝐞𝐩𝐥𝐨𝐲𝐦𝐞𝐧𝐭 𝐅𝐫𝐞𝐪𝐮𝐞𝐧𝐜𝐲: Are you shipping too fast without enough safeguards? - 𝐈𝐧𝐜𝐢𝐝𝐞𝐧𝐭 𝐑𝐞𝐜𝐮𝐫𝐫𝐞𝐧𝐜𝐞 𝐑𝐚𝐭𝐞: Has this happened before, and if so, why wasn’t it addressed? 4️⃣ 𝐓𝐡𝐞 𝐑𝐞𝐬𝐨𝐥𝐮𝐭𝐢𝐨𝐧: 𝐇𝐨𝐰 𝐃𝐢𝐝 𝐖𝐞 𝐇𝐚𝐧𝐝𝐥𝐞 𝐈𝐭? - 𝐄𝐬𝐜𝐚𝐥𝐚𝐭𝐢𝐨𝐧 𝐓𝐢𝐦𝐞: Did the issue reach the right people quickly? Or were there delays in ownership? - 𝐈𝐧𝐜𝐢𝐝𝐞𝐧𝐭 𝐋𝐨𝐠𝐬: Was the root cause and response process documented clearly, ensuring future teams can learn from it? 5️⃣ 𝐓𝐡𝐞 𝐈𝐦𝐩𝐚𝐜𝐭: 𝐖𝐡𝐨 𝐅𝐞𝐥𝐭 𝐭𝐡𝐞 𝐄𝐟𝐟𝐞𝐜𝐭𝐬? - 𝐂𝐮𝐬𝐭𝐨𝐦𝐞𝐫 𝐈𝐦𝐩𝐚𝐜𝐭: How many users were affected, and how severely? When we piece together these metrics, a clearer story emerges. We understand, where things went wrong, how the team responded, and what needs to change to prevent a repeat. “Every incident,” he said, “is like a detective story. And these metrics? They’re the clues.” I couldn’t agree more.  

Conducting accurate analysis of software defects is the key to boosting software quality and customer satisfaction. Here are the top 5 defect-related metrics that I have been capturing in my projects: 1. Defect Resolution Time: This measures the typical duration to resolve and close identified software bugs. It helps in estimating the completion of defect fixes and testing, facilitating release planning. 2. Defect Open vs Closed Trend: This metric compares the number of newly reported defects to those resolved over time. A decreasing trend in open defects, with more defects being closed over time, indicates progress towards a stable release. 3. Defect Reopen Rate: This represents the percentage of defects that reoccur after being declared as fixed. A high rate suggests potential shortcomings in fix quality or testing processes. 4. Defect Acceptance Rate: This is the ratio of accepted defects to total reported during a period. Low acceptance rates may signal gaps in domain knowledge or requirement understanding among testers. 5. Defect Leakage Rates: This refers to defects discovered post-release as a percentage of total defects found. This metric assesses the quality of testing conducted prior to product launch.

Are you customer-centric or survey-centric? According to Gartner, 80% of companies still rely on NPS as their primary feedback source for VoC Programs. If you are one of them, I have to tell you something: you don't have a Voice of Customer program. 𝗬𝗼𝘂’𝗿𝗲 𝗺𝗲𝗮𝘀𝘂𝗿𝗶𝗻𝗴 𝗿𝗲𝘀𝗽𝗼𝗻𝘀𝗲𝘀, 𝗻𝗼𝘁 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲𝘀. You’re sampling. Selectively. Superficially. And, frankly, dangerously. What most companies think is a VoC program:  • A follow-up survey after specific customer interactions  • A monthly NPS report or dashboard with sentiment scores, word clouds, and topics  • Trying to understand the root causes of these problems to convince other teams to take action What a real VoC program looks like:  • Listening across every customer touchpoint—support tickets, app behavior, product reviews, cancellation reasons, social comments  • Quantifying broken experiences to the root cause and measuring how much they impact the bottom line  • Discussing and prioritizing initiatives that will impact the bottom-line Because here’s the truth: 𝗦𝗶𝗹𝗼𝗲𝗱 𝗳𝗲𝗲𝗱𝗯𝗮𝗰𝗸 𝗴𝗶𝘃𝗲𝘀 𝘆𝗼𝘂 𝘀𝗶𝗹𝗼𝗲𝗱 𝗶𝗻𝘀𝗶𝗴𝗵𝘁𝘀. 𝗔𝗻𝗱 𝘀𝗶𝗹𝗼𝗲𝗱 𝗶𝗻𝘀𝗶𝗴𝗵𝘁 𝗰𝗿𝗲𝗮𝘁𝗲𝘀 𝗲𝘅𝗽𝗲𝗻𝘀𝗶𝘃𝗲 𝗯𝗹𝗶𝗻𝗱 𝘀𝗽𝗼𝘁𝘀—𝗺𝗶𝘀𝘀𝗲𝗱 𝗰𝗵𝘂𝗿𝗻 𝘀𝗶𝗴𝗻𝗮𝗹𝘀, 𝗽𝗿𝗼𝗱𝘂𝗰𝘁 𝗳𝗮𝗶𝗹𝘂𝗿𝗲𝘀, 𝗿𝗲𝗽𝘂𝘁𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗱𝗮𝗺𝗮𝗴𝗲. It's not about the score. It’s about the signal. Time to retire the illusion of feedback and build a real listening strategy. So I’ll ask again: Still calling that your VoC program? #CX #VoiceOfCustomer #CustomerExperience #FeedbackLoops #ProductInsights #NPS #CustomerCentricity

Most teams measure “handling time” wrong. They take the time from ticket creation to closure. Which sounds fine… until you realize 80% of that time is just waiting. Waiting for the customer to reply. Waiting for engineering to check something. Waiting for someone to take ownership. That’s not handling time. That’s calendar time. When we analyzed hundreds of tickets, we found the real signal lives inside the helpdesk logs — the moments when agents actually do something. Here’s how to measure handling time properly: 1️⃣ List every agent action on a ticket (reply, internal note, assignment, status change). 2️⃣ Sort them by time. 3️⃣ Group nearby actions — anything within 30 to 45 minutes of each other counts as one active work block. 4️⃣ Each block starts when an agent acts and ends when there’s no new activity for more than ~45 minutes, or when the ticket is set to “pending” or “on hold.” 5️⃣ Sum the duration of all those blocks. That’s your true handling time. It ignores idle gaps (like overnight waits) and focuses only on the periods when someone was actually working on the issue. It’s obviously not perfect — it won’t capture every nuance or edge case. But it already gives you a far better understanding of where your team’s time really goes than the basic “creation-to-closure” metric ever could. The difference is huge. Two tickets might both be “open” for 3 days. But one had 15 minutes of work total, while the other had 2.5 hours spread across four bursts of activity. Only one of them actually drained your team’s energy. And once you start measuring that way, new questions appear: Why do some tickets need 8 work blocks instead of 2? Why are certain ones constantly reassigned? Why does the same issue take twice as long with another agent? That’s when “handling time” stops being a vanity metric and starts revealing your real bottlenecks. Because improving support efficiency isn’t about closing tickets faster. It’s about removing friction from the work that happens between those timestamps.

𝗠𝗧𝗕𝗙, 𝗠𝗧𝗧𝗥, 𝗠𝗧𝗧𝗔, 𝗮𝗻𝗱 𝗠𝗧𝗧𝗙 🎯 In the world of reliability engineering and maintenance, metrics like MTBF, MTTR, MTTA, and MTTF play a crucial role in evaluating system performance. Here’s a breakdown of what each term means, how they relate, and their key differences: 1. MTBF (Mean Time Between Failures) • What it is: The average time a system operates before experiencing a failure. • Purpose: Measures reliability. A higher MTBF indicates fewer failures over time. • Example: A generator that runs for 500 hours between breakdowns has a high MTBF, showcasing dependability. 2. MTTR (Mean Time To Repair) • What it is: The average time taken to repair a system or piece of equipment after it fails. • Purpose: Measures maintenance efficiency. A lower MTTR reduces downtime and enhances productivity. • Example: A machine that is repaired in just 2 hours after failing demonstrates a low MTTR. 3. MTTA (Mean Time To Acknowledge) • What it is: The average time it takes to acknowledge an alert or incident after it is reported. • Purpose: Assesses responsiveness. A lower MTTA ensures that issues are addressed promptly. • Example: A monitoring system alerts a team to an issue, and they acknowledge it within 5 minutes, indicating a low MTTA. 4. MTTF (Mean Time To Failure) • What it is: The average time a system operates before its first failure. Unlike MTBF, it applies to non-repairable systems. • Purpose: Used for systems or components that are not designed to be repaired, providing insights into their lifespan. • Example: A disposable battery lasting 1,000 hours has a high MTTF. ➤How They Relate: • MTBF and MTTR: Together, they determine availability. A high MTBF and low MTTR indicate a reliable and maintainable system. • MTTA and MTTR: Combined, they highlight response and repair efficiency, critical for minimizing downtime. • MTTF and MTBF: MTTF applies to non-repairable items, while MTBF applies to repairable systems. ➤Key Differences: Metric Focus                         Repairable Systems                              Non-Repairable Systems MTBF Reliability over time   ✔️                                                       ❌ MTTR Repair efficiency         ✔️                                                       ❌ MTTA Response time              ✔️                                                       ✔️ MTTF Lifespan before failure   ❌                                                       ✔️ ✒️Why It Matters : By tracking and optimizing these metrics, organizations can: • Enhance system reliability. • Minimize downtime. • Improve maintenance strategies. • Drive better overall productivity and availability. 👉WhatsApp Channel for LinkedIn Post Update : https://lnkd.in/dHFC-mT9 l #qualitysystem #qualitycontrol #teamwork #qualityplanning #qualityinspection #problemsolving #skill #improvement #workplace  #iso9001 #qms #tqm #relaibility #maintenance #mttf #mttr #mtbf #mtta
