For production planners at a complex manufacturing site, a typical day is controlled chaos. Their morning starts by doing rounds through each work center that they manage – gathering status updates from the previous day and reviewing the
day’s schedule with their team. Once back to their desk, they synthesize the health of their production and update internal stakeholders. What happens next is a game of roulette – will it be a machine
going down, a supply chain delay, a production quality issue, misplaced documentation, a hot order booked, or another one of a hundred reasons to modify the schedule?
All that is certain is that unplanned events that impact the schedule will happen. A successful production planner must respond to these events to keeping operators productive and communicating the
impact to relevant stakeholders.
Production planning is a vital role for any complex manufacturer. As the nexus of all operations, it provides direction across many functional groups:
As if that isn’t enough, production planners must weigh business objectives in every decision they make to produce the best possible outcome for the business given the circumstances and constraints.
For an activity as mission-critical as production planning, surely there’s a market for great tools. There are niche solutions for niche industries and there are underwhelming offerings bundled with ERPs. In our experience, most complex
manufacturers can’t find a tool that fits their needs. Often, they resort to building an internal solution with either Excel or an Access database disconnected from other business systems. These solutions are often serviceable for planning
but far from ideal – specifically for distribution to the floor and visibility for the many stakeholders dependent on it.
When changes need to be made, new copies of the schedule are printed and redistributed to operators on the floor, and an update email is sent to relevant stakeholders with the latest revision. It creates clutter and introduces an opportunity
for an operator to reference an outdated schedule and throw production out of sync.
Though there are many limitations to current solutions, the root problem with production planning today is relying on humans to compute the optimal schedule and constantly recompute when something doesn’t go as expected. When things rarely
go as expected, it takes a lot of brainpower and perseverance to do this day in and day out. For many, this problem seems very familiar, and the solution seems obvious – just throw a computer at it and auto-schedule.
Sure, that sounds great, but it only addresses half of the problem.
The approach of scheduling altogether is the most critical part of the problem. Complex manufacturing is full of noise. Unlike an assembly line where cycle time is effectively fixed, the time to complete each operation varies widely. To
build a this-then-that schedule based on assumptions about upstream tasks across dozens of orders guarantees either error, production inefficiency, or both. It puts humans and computers, alike, in a can’t-win situation of projecting when the
previous task will be complete and when the order will be ready for the next work center.
Everyone knows going off-schedule is inevitable. So why don't scheduling systems account for it? Instead, it treats the unknown as the exception and requires a reaction from the production planner when an unplanned event occurs. It’s the
best a human can do, but for a computer with access to real-time progress data, the ideal solution looks much different.
Production planning in the smart factory era requires a fundamental shift in approach. Complex manufacturers don’t need auto-scheduling – they need a production planning system that allows them to do some high-level capacity planning and add
some order timeline constraints but doesn’t require the time and energy that systems do today. That system must then take those inputs and any other relevant order data to automatically implement their unique business logic and prioritize
work for the operators on the floor. That’s what we at FactoryFour intend to provide with our all-new Production Planning application.
In addition to the fundamental change in approach, there are also many limitations in the implementation of current planning solutions that need to be addressed for a fully functional application. Many of these limitations are things
FactoryFour has been specifically built to address from Day 1. The next blog in the series will review the existing FactoryFour infrastructure and functionality that makes the new application possible.
