How to implement ERP in an automotive component manufacturing company

ERP projects in automotive plants rarely fail because of the software. They stall because the data is not ready, the scope keeps growing, or the floor is asked to change how it works without being shown why. This guide sets out an approach that keeps the project small enough to finish and close enough to the floor to be used.

Before you start: decide what the system must do on day one

Write down the records your customers and your own managers ask for most often. For most component suppliers the list is short: what was made against the schedule, the lot trace for a part, the inspection results on a batch, the status of parts at vendors, and the cost of an order. Those define the first scope. Everything else can follow.

• Name an owner from the plant, usually the production or plant head, not IT alone.
• Choose the first line: one with real volume, a willing supervisor, and parts that customers query.
• Agree what will be switched off when the line goes live, such as the production register or the inspection workbook.

What data do you need to prepare?

Rates and setup times do not need to be perfect on day one. A rough figure is enough to start, and the floor's own counts will show the real rate within a few weeks.

The stages of an implementation

1. Configure the plant as it runs

Work centres, shifts, products, BOMs, routings, reason codes and inspection plans are set up in the plant's own terms. Opening stock is loaded by lot, and the accounting sync is connected. By the end of this stage a test order should run from material issue to dispatch on the screens.

2. Run the first line on real orders

Operators, supervisors and QC on the first line are trained at their stations, one short session each, and record real work orders while the rest of the plant carries on as before. Gaps show quickly: a routing that needs splitting, a missing reason code, a wrong permission. Fix them the same day.

3. Switch the first line over

The first line now runs on the system alone, and its register stops. Planning, material and cost read what the floor records.

4. Extend line by line

The remaining lines and departments follow the same pattern. Each goes faster than the last, because the masters and the training approach are already proven.

How long does an automotive ERP implementation take?

It depends on the scope, how ready the data is, and the system. A broad enterprise ERP covering finance, procurement and several plants is a much larger project than putting production, inventory and quality live on one line. FleekERP's implementation plan is built to put the first production line live in 18 days. A plant migrating years of history from another ERP, or with BOMs that need rework first, will take longer.

Common ERP implementation mistakes in automotive manufacturing

1. Configuring software before understanding the process

Setting up screens and fields before anyone has walked the floor produces a system that matches a template, not the plant. Map the real flow for one part first: where material is issued, where checks happen, what goes to vendors. Configure to that, then run the standard process for a few weeks before asking for changes.

2. Poor master-data preparation

Wrong BOM revisions, routings without work centres, opening stock without lots: each one breaks the first traces and the first costs. Clean the masters for the parts you are starting with before go-live. The opposite mistake is as common: migrating every historical transaction. Open orders, current stock by lot and active masters are usually enough, and history can stay in the old system for reference.

3. Ignoring shop-floor users

Operators and QC make most of the records, yet they are often trained last, in a meeting room. Train them at their own station on real orders, and keep their entries to the few they need: count, scrap with a reason, downtime with a cause, inspection values. In FleekERP these are made on shop floor apps on ordinary Android phones. Show supervisors their line's numbers from the first day, so the entries are used and not just collected. The article on why WhatsApp ends up running the production floor covers the habits that have to change.

4. Trying to digitise everything at once

Production, stores, quality, purchasing, dispatch and costing across every line on the same day spreads the team too thin to fix problems as they appear. One line live is worth more than five lines half configured.

5. Unclear BOM and routing ownership

If nobody owns the BOM and the routing, revisions drift: engineering changes a drawing, the routing still shows the old operation, and an order is released against the wrong one. Name an owner for each, usually engineering for the BOM and production or industrial engineering for the routing, and agree how a change is released.

6. No pilot, or a pilot with no end

Going live across the plant without a pilot means every gap appears everywhere at once. A pilot line finds them on a small scale. Set the date the pilot line's register stops, though: a pilot that runs alongside the old register indefinitely becomes a second copy nobody trusts.

7. Measuring software usage instead of operational outcomes

Logins and entry counts show whether people are using the system. They do not show whether the plant runs better. Measure the outcomes the project was meant to change.

After go-live: what to measure

• The time taken to answer a customer trace request.
• Rejection by operation and cause, reviewed weekly, and whether it is falling.
• Delivery against the customer schedule.
• Short returns from plating and heat treatment vendors caught on the order, not at month end.
• Month-end stock compared with the system, by lot.

The share of production recorded at the station is still worth watching in the first weeks, as an early sign that the outcomes will follow.
