Factory operations

The daily mechanics of running a plant — planning and scheduling work, keeping equipment available, controlling flow, and knowing what the floor actually produced.

• Asset criticality assessment: ranking equipment so maintenance effort lands where it matters

  Scoring plant assets on safety, output, quality and recovery time, then using the ranking to direct maintenance, spares and monitoring.

• Batch records: the contemporaneous account of what happened to a production lot

  Completing a batch record as the work happens, capturing deviations, reviewing before release and retrieving it when a question arises.

• Bottleneck management: finding the resource that sets output and running it properly

  How to locate the real constraint, protect its hours, handle bottlenecks that move with the mix, and decide when to spend money elevating it.

• Breakdown response: what happens in the first hour after a machine stops

  Safe isolation, triage and call-out when equipment fails, deciding between a temporary fix and a proper repair, and capturing what was found.

• Changeover management: running the switch between products without losing the day

  Getting a changeover ready before the machine stops, assigning roles, clearing first-off approval, and sequencing the plan to avoid needless switches.

• Condition monitoring: turning readings into work somebody actually does

  Running a monitoring routine that produces action: coverage decisions, baselines and alarm levels, who reviews findings, and escalation into work orders.

• Cycle time: measuring how long the work really takes at each step

  Measuring machine and operator cycle honestly, treating variation rather than averages, and separating cycle time from lead time in decisions.

• Die and mould management: looking after the assets that make the part

  Maintaining dies and moulds on a usage cycle, handling customer-owned tooling, storing and transferring them safely, and planning for tool failure.

• Downtime management: recording stoppages in a way that leads to action

  Capturing stoppages accurately, designing reason codes people can use, settling attribution arguments, and turning the record into a ranked improvement list.

• Energy management in manufacturing: turning a utility bill into a controllable production cost

  Separating baseload from production-linked energy, metering at the process, normalising consumption per unit and controlling peak demand.

• Engineering change on the shop floor: executing a change without producing mixed builds

  Implementing an engineering change in production: setting effectivity, running out old stock, updating everything at once, verifying it happened.

• Equipment replacement: choosing between keeping, rebuilding and replacing a machine

  Judging when production equipment should be rebuilt or replaced: repair spend, control obsolescence, capability gaps and timing the swap.

• Equipment total cost of ownership: what a production machine costs after the invoice is paid

  Costing a machine across its working life: installation, tooling, spares, energy, labour, support risk, downtime and eventual removal.

• Finite capacity scheduling: planning against limits the plant actually has

  When to schedule against real capacity limits, the master data quality it demands, which resources to model finite, and what to do when it says late.

• Industrial housekeeping: keeping a working floor clean enough to run safely

  The daily discipline of a clean shop floor: spills, swarf and dust, cleaning ownership by shift, clear routes and audits that mean something.

• Jigs and fixtures: controlling the devices that hold accuracy in place

  Proving a fixture before production, checking it for wear, storing and identifying it properly, and keeping it aligned with engineering changes.

• Kitting for production: when a pre-picked part set is worth the extra handling

  Deciding when to kit parts for a job, how to keep kits accurate, and what a short or wrong kit costs on the line.

• Labour planning in manufacturing: matching people to the build plan

  Converting a production plan into people by skill and shift, handling absence and agency cover, and deciding between hiring, overtime and flexibility.

• Line balancing: sharing work content so no station sets the pace alone

  Splitting work content across stations, finding and fixing the slowest one, handling mixed-model lines, and knowing when to rebalance.

• Line-side material supply: feeding the station without burying it in stock

  Replenishing parts at the point of use: presentation, trigger signals, contested floor space and what a station stockout really costs.

• Machine utilisation: what the figure means and how it misleads people

  Defining machine utilisation honestly, choosing a denominator, and why pushing it up away from the constraint destroys more than it earns.

• Maintenance management: running the function that keeps the plant available

  Choosing the mix of maintenance strategies, controlling the work order backlog, funding the function properly, and measuring it on plant availability.

• Maintenance outsourcing: deciding which work leaves the in-house crew

  Choosing which maintenance work to contract out, how to shape the contract, and how to keep asset knowledge inside the plant.

• Maintenance planning: turning a work request into a job the crew can execute

  How maintenance planning converts requests into ready job packages, grooms the backlog and protects weekly schedule compliance.

• Material handling inside the factory: moving parts between operations without damage or delay

  Internal material flow between operations — unit loads, transport routes, handling damage, double handling and who owns the moves.

• Multi-skilling on the line: buying flexibility without losing competence

  Deciding which cross-skills to fund, running a skills matrix that means something, handling pay and grading friction, and keeping rarely used skills current.

• New product introduction on the line: getting a design into serial production without wrecking the schedule

  Taking a new product from pilot builds into serial production: line readiness, ramp planning, operator learning and the cutover.

• Order release: the gate between a plan and work actually starting

  When a works order should be allowed onto the floor: release checks, holding a pre-release pool, and the harm caused by releasing early.

• Predictive maintenance: acting on a warning before the machine stops

  Turning an early warning into a decision: setting intervention thresholds, replanning production around it, ordering parts, and living with false alarms.

• Preventive maintenance: setting intervals and actually keeping them

  Choosing time-based or usage-based intervals, writing task content worth doing, protecting compliance from production pressure, and pruning waste.

• Production batching: choosing how much to run before you change over

  How batch size is really decided on the shop floor: changeover cost, campaign runs, transfer batches and quality exposure per lot.

• Production capacity planning: working out what the plant can really make

  Nameplate versus demonstrated capacity, why mix changes the answer, the ladder of capacity levers, and the lead time cost of running near the ceiling.

• Production control: closing the loop between the plan and what was built

  The control loop from order release to closure: what is monitored, what triggers intervention, who holds authority, and how variance gets attributed.

• Production documentation: the working papers at the station and keeping them current

  The document set an operator needs at the point of use, how revisions stay current there, and how obsolete copies leave circulation.

• Production loss accounting: explaining the gap between the plan and the output

  Building a loss tree that accounts for every unit and minute between theoretical capacity and actual good output, with owners attached.

• Production planning: turning a demand picture into a buildable plan

  How planners convert demand into a buildable plan, set the horizon and the frozen period, and stop plan churn from wrecking the shop floor.

• Production reporting: the daily figures a plant is actually run on

  The reporting rhythm of a factory: what each shift reports, to whom, at what cadence, and how to stop the numbers being negotiated.

• Production scheduling: deciding what runs next on which machine

  Sequencing work across machines and shifts: which dispatch rule to use, what data a schedule needs, and when to reschedule instead of absorbing.

• Production sequencing: choosing the order jobs run on a given machine

  Setting the running order at a work centre: sequence-dependent setup, dispatch rules, sequence stability and who may break it.

• Production waste handling: segregation at source, on-site storage and the record that follows the skip

  Segregating factory waste where it is created, storing it safely, classifying hazardous streams and keeping the transfer records straight.

• Reliability-centred maintenance: choosing a policy for each way a machine fails

  Working failure mode by failure mode to decide the maintenance policy, who belongs in the analysis, where the effort pays, and how to keep the output alive.

• Rework management: deciding what gets fixed, what gets scrapped, and what the fixing costs

  Disposition decisions on nonconforming product, routing and recording rework properly, and why spare rework capacity hides real problems.

• Rough-cut capacity planning: sanity-checking the schedule before it costs money

  Testing a master schedule against a short list of key resources, reading an overload correctly, and deciding before purchase commitments are made.

• Scrap control: measuring, attributing and acting on material lost in production

  Recording scrap where it was generated, coding the cause, valuing it at the right point in the route and acting on the pattern.

• Serial number management: allocating, marking and following individual units through the plant

  Allocating serial numbers, marking units so they survive the process, capturing them at the right steps, and handling rework and scrap.

• Shift handover: transferring control of a running process between crews

  Structuring the transfer between outgoing and incoming crews: what must cross, overlap time, written and verbal record, unfinished work.

• Shift management: choosing a pattern the plant and the people can both sustain

  Selecting a shift pattern, covering absence without permanent overtime, managing fatigue and night working, and costing the pattern honestly.

• Shop floor control: what the supervisor decides between the plan and the product

  The supervisor's execution layer: dispatch priorities, the escalation ladder, controlling the span of attention, and the short interval control routine.

• Shop-floor data capture: what gets recorded, by whom, and what it is for

  Choosing which production events are recorded on the floor, who records them and when, and how to keep the resulting data honest.

• Spare parts management: deciding what to hold before the machine needs it

  Stocking spares by failure consequence and lead time, controlling the storeroom, dealing with obsolescence, and keeping the parts data usable in a breakdown.

• Takt time: setting the pace a line has to keep to meet demand

  Choosing the demand window and net available time behind a takt figure, running below it deliberately, and managing what happens when takt changes.

• The master production schedule: the commitment the whole plant plans against

  What an MPS commits to, where to set it in the bill of material, how time fences work, and how order promising is answered from it.

• Theory of constraints on the factory floor: what it changes in practice

  The focusing sequence, drum-buffer-rope release, buffer management as a daily routine, and the policy constraints that usually block the whole approach.

• Throughput management: protecting the rate of saleable output

  Managing the rate of good product leaving the plant, why local efficiency fights it, and how to run the daily rate check that catches shortfalls early.

• Tooling management: keeping cutting and forming tools where the job needs them

  Controlling tool issue and return, setting tool life policy, presetting and regrind cycles, and preventing missing tooling from stopping the machine.

• Utilities monitoring: compressed air, steam and cooling as production inputs

  Tracking compressed air, steam, chilled water and vacuum so losses are found and utility cost is attributed to the process consuming it.

• Water in production: matching quality grade to use, closing reuse loops and staying inside consent

  Managing process water in a plant: quality grades, a water balance that closes, cascade reuse, and discharge consent as a live constraint.

• Work in progress control: keeping the floor from filling up with unfinished work

  Capping work on the floor, finding where unfinished stock hides, dealing with aged and orphaned jobs, and keeping the physical count believable.

• Works order management: the life of the document that authorises production

  Raising, issuing, booking and closing works orders — revision snapshots, material issues, variances and open-order hygiene.

• Yield management: knowing how much good product a process really gives you

  Defining yield at each step, rolling it across a route, keeping standard yields honest in costing, and catching drift before it normalises.
