80% utilization sounds efficient. The math says otherwise. At 80% utilization, your expected wait time for any work item is 4x longer than at 50% utilization. This isn't opinion, it's Kingman's formula, and it explains why your "efficient" organization moves so slowly. Here's the equation that every executive should have tattooed on their forearm: Expected Wait Time = (% Utilization / (1 - % Utilization)) × Variability Coefficient × Average Process Time Run the numbers: * At 50% utilization: 6.5 minutes expected wait * At 70% utilization: 15.2 minutes expected wait * At 80% utilization: 26 minutes expected wait Double the utilization. Quadruple the wait time. Your CFO sees slack as waste. Your customers experience it as speed. This is why the most adaptive organizations prioritize flow efficiency over resource efficiency. Flow efficiency measures the ratio of value-adding time to total time. Resource efficiency measures how busy your people are. When you optimize for keeping everyone busy, you create queues. Queues create waiting. Waiting creates delays. Delays kill adaptability. The counterintuitive solution? Design for flow first. Then improve interactions to increase resource efficiency while maintaining that flow. Your people looking "underutilized" might be the reason your organization can actually respond to market changes. What would happen to your delivery speed if you stopped treating slack as a problem to solve? #SimplificationOfficers #FlowEfficiency

The paradox of WIP limits contradicts every instinct about productivity. When demand increases, your natural response is taking on more work. Keep everyone busy. Maximize utilization. That's when delivery slows down. Little's Law explains why. Average cycle time equals work in progress divided by throughput. When WIP increases, cycle time increases proportionally. More items in the system means each item takes longer to complete. Context switching increases. Bottlenecks intensify. Quality issues emerge because nothing gets full attention. The solution feels counterintuitive. When pressure builds, lower your WIP limits instead of raising them. Fewer items in progress means each item moves faster. Faster movement means more completions. More completions reduce the backlog. The teams I work with resist this initially. Then they test it for two weeks. Cycle times drop by 30-40%. They never go back to the old way. Less work in progress creates more work completed. That's the paradox that accelerates delivery. #NavigateYourFlow #WIPLimits #LittlesLaw #FlowMetrics #Kanban

Most teams track how fast they finish work. But few pay attention to how much they start—and that’s what really controls flow. This WIP Run Chart shows it clearly: when Work In Progress (WIP) climbs, Lead Time stretches; when WIP stabilizes, delivery becomes predictable. In our Kanban workshops, we use the M E T R I C framework to make each flow metric teachable: Meaning • Example • Tips & Traps • Reflective Questions • Improvement Experiments • Collect & Connect. Here’s the WIP version—a one-page learning guide for making flow visible. 🔹 Lower WIP → Shorter Lead Time 🔹 Stable WIP → Predictable Flow How do you keep your WIP steady without slowing delivery? #Kanban #FlowMetrics #Agile #Lean #ContinuousImprovement PS. My first version of this one. If you see any issues, please let me know.

Yet another reason estimates are ridiculous. One of the silliest things about time estimates is that the vast majority of time it takes for a team to finish something is spent waiting. For the average development team to create something of value, only 10-20% of the total start-to-finish completion time is spent actively working on the item. The majority of the time is spent waiting. 🔵 Waiting for Reviews 🔵 Waiting for team member hand-offs 🔵 Waiting on other teams or departments So much time is spent waiting… instead of asking, “How much time will it take WORKING to complete this?” You’d be better off asking, “How much time will it take WAITING to complete this?” This, of course, is impossible to answer since most teams have zero control (or even awareness) of waiting time. You’re far, far better off ditching time estimates entirely and focusing on reducing wait states instead. But how? 1] Use Flow Efficiency ↳ Few teams are even aware of the most critical flow metric: Flow Efficiency. ↳ Flow Efficiency tells you how much time is spent actively working on increments of value (features, assets, stories, etc.). ↳ Flow Efficiency (%) = Active Time / Total Time X 100 ↳ Any good workflow tool will calculate your Total Time (Cycle Time). 2] Determine Active Time ↳ To figure out Active Time, you need to track your wait states by adding a “Done” state to every existing stage in your workflow. ↳ For Example: Development -> Development Done -> Testing -> Testing Done -> Review -> Review Done -> Released ↳ The “Done” columns are your wait states.  ↳ Now, you can effectively determine Active Time for each item in your flow vs. Wait Time. 3] Improve Flow Efficiency ↳ Once you can visualize and track wait times, you can focus on fixing the worst offenders. ↳ Add team members, reduce work in progress, remove dependencies… there are many ways to minimize wait states. ↳ Any reduction made to any of your wait states will improve Flow Efficiency An average team will have a Flow Efficiency of 20%. Your team should achieve a Flow Efficiency of 40% or greater to be considered high-performing. Will this take some effort? Of course! But far less effort and total team time (and annoyance) than asking for estimates. Plus, the increase in productivity will far outweigh any loss in imagined predictability.

Have you ever heard about "Flow efficiency"? Businesses typically chase "Resource efficiency". It's all about keeping everyone busy, maxing out utilization. But in that obsession, they tank something called "Flow efficiency", the real key to speed and value. Flow efficiency tracks how much of a process’s total time is spent actually working on a task versus waiting around. Think of a support ticket. It's opened on Monday morning and closed on Friday evening, a total of five days. But the team only spent 4 hours actively talking, troubleshooting, resolving, testing etc.. That’s 4 hours of work in 40 hours of elapsed time, a flow efficiency of just 10%. The rest? Waiting on escalations, approvals, or someone to free up. Here’s the catch: Measuring that split (active work vs idle time) is super tricky. It requires being able to track active work time, pinning down delays. Most companies don’t even try. Yet when they do, the numbers shock. Flow efficiency often limps along at 5-15%. That means 85-95% of the time, work is just sitting there, stalled by: - Stakeholder approvals - Handoffs and dependencies - Resource bottlenecks Why do some businesses struggle with this? - Too Many Handoffs → Each pass between teams or departments piles on wait time, especially in sprawling organizations. - WIP Overload → Juggling too many tasks at once drags everything to a crawl. Nothing finishes fast. - Approval Chokepoints → Decision makers, swamped themselves, become the jam in the pipeline. - Misaligned Goals → Success is tied to “busyness” metrics, not how fast value hits the table. - Priority Fog → When everything’s urgent, focus scatters, and momentum dies. How to break through? First → Measure! You can't improve something you don't measure. Next → Cut work in progress. Slash unnecessary handoffs. Speed up approvals. Automate where you can, empower teams to decide where you can’t. Above all, ditch the “busy is best” mindset. Focus on delivering value, not filling hours. Measuring flow efficiency isn’t easy. But mastering it? That’s less friction, faster wins.
