Methods and scheduling: defining how things are made and in what order, with a schedule that keeps up with reality.
Methods write the routings, standard times and instructions; scheduling turns requirements into production orders and a shop-floor schedule. Both spend a large share of their time copying: recorded times into the ERP, priorities into a scheduling spreadsheet, changes into production records. Automation keeps that data accurate and recalculates the schedule when the day does not go as planned.
The role
Between the engineering office, the supply chain, the workshop and quality.
Methods industrialise the product: manufacturing bills of materials, routings, work centres, standard times, tooling, work instructions. Scheduling releases production orders, sequences them on the work centres and holds the schedule against disruptions: breakdowns, late materials, absences, customer emergencies. In a mid-sized company, both roles are often held by the same small team, which links what the ERP plans with what the workshop can really do.
Day to day
A typical day.
- MorningCheck the progress of the previous day’s production orders and the variances against the schedule.
- MorningCheck component and tooling availability before releasing the day’s orders.
- MiddayReschedule after a disruption: breakdown, late material, absence, urgent order to insert.
- AfternoonUpdate a routing or a bill of materials after an engineering change.
- AfternoonAnalyse variances between standard and actual times, and prepare improvement actions.
- End of dayFreeze the next day’s schedule and send it to the team leaders.
The objectives
What the role is measured on.
- Schedule adherence
- Reliability of standard times
- Load and capacity by work centre
- Late production orders
- Changeover time
- Work in progress
Indicators are named, never quantified: levels depend on each company, and the diagnostic measures them.
Day to day
The problems that come up most.
A schedule that lives in a spreadsheet
The ERP calculates requirements, but the real sequence is built alongside it, by hand, and stops being updated at the first disruption.
Standard times that never move
Routings carry times set at industrialisation, far from actual times, which distort load and costs.
Orders released without all their components
A shortage discovered at the workstation stops the order midway and disrupts the sequence.
Engineering changes poorly propagated
A bill of materials changes in the engineering office, but orders already released and workstation instructions keep the old version.
Work instructions that take long to maintain
Each item has its documents, photos and settings; updating them takes longer than changing the process.
Disruptions absorbed by hand
A breakdown or an emergency means resequencing everything by phone, without seeing the effect on other orders.
By sector
One role, several realities.
- Fashion and luxury
Leather goods, couture or jewellery workshops, craft routings and rare skills, small runs and special pieces, work split between in-house workshops and contract makers.
- Cosmetics and beauty
Bulk manufacturing then filling, campaigns by shade, fragrance and format, cleaning between products, bulk shelf-life constraints and fixed-date launches.
- Industry
Machining, assembly or processing workshops, multi-operation routings and work centres, subcontracted operations, small and medium runs to pace on shared capacity.
- Pharma and healthcare
Scheduling under GMP, validated campaigns and cleaning, dedicated or shared equipment, batch records to prepare, in-process controls and release lead times to build into the schedule.
What changes
Automate the task, keep the judgement.
What gets automated
- Production schedule recalculated from the ERP, real capacities and sequencing constraints, with a new calculation at each disruption.
- Automatic check of components, tooling and authorisations before each production order is released.
- Actual times recorded at the workstation and compared with standard times, with a proposed routing update.
- Propagation of engineering changes to routings, bills of materials, open orders and workstation instructions.
- Work instructions generated from the routing and photos, with an AI agent drafting the first versions.
What stays human
- Priority calls between orders, and the choice of what to push back.
- The definition of the process, the work centres and the reference times.
- Approval of work instructions and changes with quality and the workshop.
Use cases
How to automate, case by case.
Each case starts from a question leadership teams ask. The starting point, what gets automated, the tools involved, and what stays in the teams’ hands.
How do you automate the production schedule?
- Today
- The ERP calculates requirements and proposes production orders, but the scheduler builds the real sequence in a spreadsheet, work centre by work centre, based on what they know about the machines and the teams. The schedule is distributed on paper, and becomes wrong at the first disruption.
- What gets automated
- Orders, routings, capacities by work centre and sequencing constraints are taken from the ERP into a scheduling tool that calculates a feasible sequence. The schedule is published at the workstations and updates with the workshop’s declarations. Each order shows its planned finish date, compared with the date promised to the customer.
- What stays human
- The scheduler approves the sequence and settles priorities between orders.

How do you automate creating and updating manufacturing routings?
- Today
- Routings are entered by hand in the ERP at industrialisation, often by copying a similar item. Operations, work centres and times are then corrected as comments come in from the workshop, with no record of what changed or why.
- What gets automated
- A new routing starts from a product family and approved operation templates, completed by methods. Variances recorded at the workstation, times, work centres actually used, operations added, are grouped and proposed as an update. Each routing version is traced with its author, date and reason.
- What stays human
- Methods define the process and approve each routing version.

- PLM
- MES
How do you automate the release of production orders?
- Today
- Before releasing an order, the scheduler checks component stock in the ERP, calls the stores, makes sure the tooling is available, then prints the file. A shortage discovered once the order is released blocks the workstation.
- What gets automated
- For each order to release, the tool checks available stock, expected receipts, reservations, tooling and authorised operators. Complete orders are proposed for release, with the picking request sent to the stores; incomplete orders are flagged with what is missing and the expected availability date. The production file is generated at the right version.
- What stays human
- The scheduler decides whether to release an incomplete order, push it back or split it.

How do you automate updating standard times from actual times?
- Today
- Standard times were set at industrialisation and rarely reviewed. Actual times are declared on paper or not at all, and the gap distorts both the load calculation and the cost price.
- What gets automated
- Operators declare the start, finish and stoppage of each operation on a tablet, or the PLCs do it. The tool compares actual times with standards, sets aside outliers and flags operations where the variance persists. A proposed new time is submitted to methods, with the history that supports it.
- What stays human
- Methods approve the new reference time and look for the cause when the variance comes from the process.

How do you automate writing workstation work instructions?
- Today
- Each item has its instructions, written in a word processor with photos. Updating them after a change takes time, and operators sometimes work from an old printed version.
- What gets automated
- Instructions are built from the routing, the settings and photos taken at the workstation; an AI agent drafts a clear first version, step by step, which methods rework. After approval, the instruction is displayed at the right version on the workstation tablet, linked to the order in progress. A routing change flags the instructions to review.
- What stays human
- Methods and quality approve the content of each instruction before release.

- Document management software
- MES

How do you automate load and capacity calculation by work centre?
- Today
- To know whether the workshop can absorb an order, the scheduler adds up the times of planned orders in a spreadsheet and compares them with a theoretical capacity. Absences, planned maintenance and real yields are not included.
- What gets automated
- Load is calculated from firm and planned orders in the ERP and routing times. Capacity takes into account scheduled shifts, leave, preventive maintenance planned in the CMMS and observed yields. Overloaded work centres are flagged by week, with the orders concerned.
- What stays human
- Production and scheduling decide on overtime, subcontracting or pushing orders back.

How do you automate the sequencing of production campaigns?
- Today
- On a shared line, the order of production runs determines cleaning and format changes: moving from a light shade to a dark one, from one product to another, from one format to another. The scheduler composes campaigns from memory and the rules are written down nowhere.
- What gets automated
- Changeover rules between products are described once with production and quality: required cleaning, changeover times, forbidden sequences. The scheduling tool groups orders into campaigns and proposes the sequence that respects these rules and customer dates. The required cleaning steps are added to the schedule and the production records.
- What stays human
- Scheduling approves the sequence; quality remains in charge of the cleaning rules, validated on site.

- ERP
- MES
How do you automate the calculation of standard manufacturing cost?
- Today
- The standard cost of each item is calculated in a spreadsheet from the bill of materials, the routing and hourly rates updated once a year. When a component or a time changes, the cost is not recalculated and selling prices rest on an outdated figure.
- What gets automated
- The cost price is recalculated automatically from the bill of materials, the latest purchase prices, routing times and cost-centre rates. Any change to a component, time or rate triggers the recalculation of the items concerned. Variances between standard cost and the actual cost of closed orders are tracked by item.
- What stays human
- Management control approves the rates and the method, and management decides how prices are affected.

- Business intelligence (BI) tool

How do you automate engineering changes to bills of materials?
- Today
- The engineering office changes a component and sends an e-mail. Methods update the bill of materials in the ERP, but orders already released, the old component’s stock and workstation instructions follow late.
- What gets automated
- Each change goes through a request stating what changes, the effective date and how old stock is handled. Once approved, the bill of materials, routing and instructions concerned are updated together, and open orders are listed for decision. The version history remains available by item.
- What stays human
- The engineering office, methods and quality approve the change and decide what happens to stock and orders in progress.
- PLM
- ERP
- Document management software
How do you automate rescheduling after a production disruption?
- Today
- A machine breaks down, a material does not arrive, a team is short-staffed. The scheduler resequences by phone, moves orders in their spreadsheet and only then finds out which customer orders have slipped.
- What gets automated
- The declared disruption, a breakdown in the CMMS, a late receipt in the ERP, an absence in the staff schedule, is picked up automatically by the scheduling tool. A new sequence is proposed with its effects: orders pushed back, customer orders affected, work centres freed up. Once approved, it is published at the workstations and the dates are updated for sales administration.
- What stays human
- The scheduler chooses between the proposed scenarios and warns sensitive customers with sales administration.

Questions from the teams
What teams look to improve.
- How do you automate workshop scheduling?
- By starting from the data the ERP already holds: production orders, routings, bills of materials, work centres. Add the real capacities, the sequencing constraints and component availability. A scheduling tool calculates a feasible sequence, recalculates it at each disruption and shows the effect on customer dates. The scheduler keeps the trade-offs.
- Do you need advanced planning software on top of the ERP?
- Not always. When constraints are simple, the ERP and a connected tool are enough. When sequences depend on changeovers, cleaning or shared resources, a dedicated scheduling tool is justified. The diagnosis tells, based on the real constraints.
- How do you make standard times reliable?
- By recording actual times at the workstation, order by order, without heavy data entry: start and finish on a tablet, or through the PLCs. Recurring variances between actual and standard times are flagged, and a routing update is proposed to methods, who approve it.
- Can AI build the production schedule?
- It helps build and correct it: propose a sequence, spot a resource conflict, explain the effect of a disruption. The calculation rests on reliable rules and data, and priority choices remain with scheduling and production.
- How do you avoid releasing a production order without its components?
- Through an automatic check before release: available stock, expected receipts, existing reservations, tooling and authorised operators. Incomplete orders are flagged with what is missing, and the scheduler chooses to push them back or release them in part.
- How do you connect the schedule to the workshop in real time?
- By displaying the schedule at workstations or on tablets and picking up start, finish and stoppage declarations. The schedule updates with reality, and the scheduler sees delays as they arise.
- How do you manage bill of materials changes without errors?
- Through a change workflow that states what changes, from when, and what happens to stock and orders in progress. Once the change is approved, the routings, bills of materials and instructions concerned are updated together, and open orders are flagged.
- Can methods work be automated in a GMP environment?
- Yes, by respecting change control and system validation: any change to a process or a batch record goes through the site’s quality workflow. Automation prepares and traces, quality assurance approves.
