IBP Is Not a Forecasting Process (Despite What Everyone Thinks)

Every time a company decides to “implement IBP,” the conversation usually starts the same way. “We need a better forecast.” And just like that, the entire organization begins a heroic quest to improve forecast accuracy — new software, new models, more meetings, more spreadsheets, more debates about whether next month should be up 3% or down 2%. Meanwhile, leadership is quietly hoping this will somehow fix inventory, service, profitability, growth, capacity constraints, and the general feeling that the business is being run by a series of surprises. Unfortunately, a better forecast will not solve those problems. A forecast is simply…

Why Executive Leadership Wins With Integrated Business Plannin

Every executive I know is drowning in data — dashboards, forecasts, KPIs, scenario models — yet still feels like they are flying blind when it matters most. This isn’t a data problem. It’s a decision problem. Integrated Business Planning (IBP) exists for one reason: to give executive leadership a single, trusted version of the business so they can make the right decisions at the right time, before problems become expensive. IBP quietly becomes one of the most powerful leadership tools in a company because it replaces reaction with foresight. Instead of managing by exception — waiting for something to break…

Truth Beats Stretch: An S&OE Story

On Monday at 8:07 a.m., the war room smelled like dry-erase and coffee. Ravi, the supply planner, clicked his laptop shut with a little flourish. “Good news,” he said. “I bumped the plan eight percent. Bit of a stretch, but it’ll light a fire.” Maria, who ran the bottleneck filler line, raised an eyebrow. “We have one filler,” she said. “It runs at one filler speed.” “Totally,” Ravi said. “But if we aim higher, we’ll get more. People step up.” By noon the “stretch” had turned into schedule musical chairs. To hit Ravi’s number, the plan jammed in two extra…

“You can’t ship to last Tuesday” — Why Past-Due Orders Don’t Belong (and how they drive planners out of the system)

Time travel isn’t a supply strategy. Yet many ERPs carry past-due production, purchase, and transfer orders—ghost promises from yesterday. Keeping them doesn’t make you on time; it breaks your ERP, corrodes behavior, and pushes planners to run the business in spreadsheets. Here’s why those zombies need to go—and what to do instead. Why past-due is poison A past-due order is an open supply order with a due date earlier than today. Every day it remains late, your system pretends yesterday had infinite capacity and suppliers teleported parts. Cute fiction; ugly consequences. What it does to your ERP Lies to Sales…

Supply Plan vs. Demand Plan — What’s the Difference and Why It Matters

Think of the demand plan as the company’s best read on the market—an unconstrained forecast of what customers will buy if nothing gets in the way. It’s built from history, seasonality, price and promo plans, sales pipeline, and a healthy dose of competitive intel. It should be honest about uncertainty and explicit about assumptions, because its job is to preserve a clean market signal and highlight revenue risk and opportunity. The supply plan hears that signal and replies, “Great—here’s the constrained, feasible way we’ll make, buy, and ship it.” Supply translates the demand plan into real-world actions: purchase orders, production…

Navigating the Complexities of S&OP: Beyond Demand Planning

In the realm of Sales and Operations Planning (S&OP), demand planning is often portrayed as the primary culprit when things go awry. It's easy to assume that inaccuracies in forecasting and demand projections are the root causes of S&OP process challenges. However, in reality, demand planning isn't always the problem. This article aims to shed light on why other factors within the S&OP process can also contribute significantly to its success or failure.

Order Control Gone Haywire: A Hilarious Guide to managing orders during a constrained supply situation

One of the challenges in the Integrated business planning (IBP) process is aligning the outcome of the monthly IBP process with the short-term tactical horizon.  It happens like this:  The demand review from the commercial team provides an unconstrained demand plan.  Supply Chain review responds with their known constraints that cannot be overcome, it is decided that the commercial team is then forced to constrain the demand plan and then supply chain is able to develop a supply plan that is both realistic and achievable.  The process works great! Right?  But not so fast, the customer, aware that there is…
