Planning production today: excel or dedicated software?

Digitalization starts with a concrete choice

The digitalization of the manufacturing world is not a linear path. Unlike administrative and management areas — where the adoption of software and ERPs has occurred gradually — production requires a more targeted approach. Every change directly impacts the heart of the business, and the margin for error is reduced to a minimum.

Yet even today, a great many manufacturing companies still plan their production with Excel. Not because it is the best choice, but because it is the familiar one. And this familiarity comes at a cost — often invisible, but very real.

Excel: powerful but not built for production

Excel is an extraordinary tool. Flexible, accessible, and familiar to everyone. That is why it has become the most widely used “planning software” in the world — even in environments where it should not be.

However, using Excel to plan production means running up against structural limits, sooner or later:

• Isolated, non-real-time data. Every file is an island. Information on orders, inventory, machine availability, and processing times lives in separate documents, manually updated and often not aligned.
• No visibility into production capacity. Excel does not know how many machine hours you have available, which resources are already committed, or where a bottleneck is. All of this has to be calculated by hand.
• Fragile by design. A shared file that three people work on generates conflicts, duplicate versions, and formula errors. Planning becomes an exercise in trust rather than in control.
• No reliable simulation. What happens if a supplier is late? If an urgent order enters production? With Excel, every scenario requires hours of manual rework.
• Zero scalability. When complexity grows — more SKUs, more customers, more variables — Excel does not grow with you. What grows is only the number of sheets, the size of the files, and the errors.

The result? Decisions made with incomplete data, late deliveries, oversized inventories or, on the contrary, production stoppages due to missing materials.

Dedicated software: planning with awareness

A production management software system is not simply “a bigger Excel.” It is a tool designed from the ground up to address the complexity of the production floor, with logic, algorithms, and data flows that Excel cannot replicate.

The difference is not only technological. Above all, it is a matter of decision-making: with dedicated software, every planning choice is supported by real, up-to-date, and integrated data.

The NET@PRO modules: from planning to optimization

The NET@PRO suite offers an integrated ecosystem of tools designed to respond in a scalable way to different planning needs.

APS Planner and MRP II — Calculating what you need, when you need it

The APS Planner module with MRP II (Manufacturing Resource Planning) turns sales forecasts into concrete production plans. Unlike an Excel spreadsheet, this module:

• automatically calculates requirements for raw materials, semi-finished goods, and components
• estimates the required production capacity and compares it with the capacity available
• coordinates material availability with actual production times
• plans procurement and in-house production in a consistent way

The continuous dialogue with the logistics modules eliminates the misalignments typical of a system based on separate files.

APS and Sequencer — When complexity grows

When the variables multiply — more machines, more shifts, more constraints — APS (Advanced Planning and Scheduling) and the Sequencer come into play.

With Excel, simulating an alternative scenario takes hours. With APS, that time is drastically reduced: it becomes possible to verify the impact of a change in real time, commit delivery dates with reliability, balance loads and resources with optimized algorithms, and respond promptly to variations in demand or operational issues.

The Sequencer handles short-term scheduling — daily activities, shifts, micro-variations — through an interactive graphical interface that definitively replaces grids of colored cells.

DDMRP — Agile, demand-driven production

For companies operating in highly variable markets — make-to-order production, variable lot sizes, short response times — NET@PRO integrates the DDMRP (Demand Driven Material Requirements Planning) module.

While Excel has no way to react autonomously to changes in demand, DDMRP synchronizes production with actual demand, defines dynamic material buffers to absorb fluctuations, and reduces the “bullwhip” effect along the entire supply chain.

MRP II, APS, DDMRP: which one to choose?

There is no one-size-fits-all solution — and this is precisely one of the strengths of NET@PRO. Each module can be adopted progressively, based on the company’s digital maturity:

Many companies choose a complementary approach: MRP II for operational planning, APS for strategic scheduling, and DDMRP for reactive demand management.

The real cost of Excel in production

Before deciding to “stick with Excel a little longer,” it is worth asking: what is the real cost of a late delivery? Of a miscalculated requirement? Of a production stoppage due to unavailable materials?

These are not software problems. They are business problems — and they often arise precisely from the lack of adequate tools.

Switching to dedicated software does not mean turning processes upside down overnight. It means starting to plan with real data, integrating information that is scattered today, and making decisions with more control and less guesswork.

Plan well to produce better

The digitalization of production is not a leap into the void, but a process that requires concrete tools, in-house skills, and a clear vision of the objectives. The Planner, Sequencer, MRP II, and DDMRP modules of NET@PRO offer an integrated ecosystem to plan, simulate, and optimize every phase of the production process — in a progressive and measurable way.

Today, the ability to plan well is one of the main competitive factors for manufacturers. And equipping yourself with solutions designed for production — not adapted from other contexts, much less from a spreadsheet — is the first step toward producing better, with less waste, fewer delays, and greater control.
