Manufacturing Execution System (MES) Development

Introduction

What Does a Manufacturing Execution System Do?

A Manufacturing Execution System, or MES, is the operational layer between ERP and the shop floor. It receives production orders, sequences and dispatches work, tracks execution in real time, records output, scrap, downtime and quality events, and returns accurate production data to ERP. Tech4LYF develops modular MES solutions for Indian manufacturers, allowing plants to begin with their highest-priority workflow and expand without replacing existing systems.

ERP tells the organisation what should be produced, in what quantity and by when. MES controls how that plan is executed across work centres, machines, operators, tools and materials. It replaces disconnected spreadsheets, paper travellers and delayed shift reports with a shared view of what is running, what is waiting, what has stopped and what requires attention.

Following the ISA-95 manufacturing architecture, MES operates between business-planning systems such as ERP and shop-floor systems such as PLCs, SCADA, sensors and machines. This creates a controlled information flow: approved production orders move downward for execution, while actual production, material consumption, quality and downtime information moves upward for planning and reporting.

Tech4LYF can integrate MES with Odoo, SAP, Oracle, Tally-connected systems or a custom ERP. On the shop-floor side, information can be captured through PLCs, OPC UA, Modbus, machine APIs, IoT gateways, barcode scanners, operator terminals or manual forms. Plants with older machines can start with operator-assisted tracking and add automated data capture where the operational value justifies it.

Our modular approach avoids forcing every MES function into the first release. A plant may begin with production dispatch and tracking, quality traceability, downtime capture or digital work instructions. Additional modules can then be introduced after users and production data have stabilised.

What Your Manufacturing Team Gains from MES

MES gives production, quality and management teams a shared source of operational truth. Instead of waiting for end-of-shift reports, they can identify delays, quality risks and production losses while corrective action is still possible.

Live Production Visibility

See order progress, output, cycle variance, downtime, scrap and work-in-progress by line, work centre, shift and product.

Faster Production Response

Highlight stopped operations, delayed orders, missing materials and quality holds so the responsible team can act sooner.

End-to-End Traceability

Maintain batch, lot or serial-level genealogy across materials, machines, operators, process parameters and quality results.

Quality at the Source

Embed inspection plans, specifications, approvals and non-conformance workflows directly into production execution.

Reliable ERP Feedback

Return actual quantities, scrap, material consumption, labour and completion status to ERP without repeated manual entry.

Modular, Scalable Rollout

Start with one line or one operational problem and expand across modules, plants and integrations as adoption grows.

Core MES Capabilities

Tech4LYF configures the MES around your production model, data availability and operating priorities. Modules can be introduced independently and connected as the deployment expands.

Production Order Dispatch Receive approved production orders from ERP, release them to the correct work centres and communicate priorities, quantities and due dates to production teams.
Work-Centre Scheduling Sequence jobs by shift, machine, line, product, tool or available capacity while giving supervisors controlled options to respond to shop-floor changes.
Real-Time Production Tracking Track planned quantity, actual output, work-in-progress, cycle progress and order completion using machine data, barcode scans or operator input.
Machine and PLC Integration Capture status, counts, process values and operating events using OPC UA, Modbus, machine APIs, PLC tags, gateways or retrofit sensors.
Downtime and Scrap Capture Record automatic and operator-confirmed downtime, reason codes, scrap quantities and production losses for shift-level and historical analysis.
In-Process Quality Control Present inspection requirements at the correct operation, capture results and manage holds, deviations, rework and non-conformance approvals.
Batch, Lot and Serial Traceability Build product genealogy connecting incoming materials, process steps, machines, operators, inspection results and finished products.
Digital Work Instructions Deliver the correct drawing, SOP, checklist or work instruction according to product, process, machine and revision.
OEE and Production Analytics Analyse availability, performance, quality, output, downtime and changeover losses using consistently captured production events.
ERP, QMS, WMS and CMMS Integration Exchange production orders, material requirements, quality status, maintenance events and confirmed output with the systems already used by your business.

Our Development Process

01
MES Scoping Workshop

Map production workflows, systems, machines, data sources, reporting gaps and the operational problem that the first release must solve. Indicative duration: one to two weeks.

02
Solution and Integration Blueprint

Define module boundaries, ERP ownership, MES responsibilities, machine connectivity, master data, user roles and measurable acceptance criteria. Indicative duration: one to two weeks.

03
Data and Connectivity Layer

Configure ERP interfaces, PLC or machine connections, gateways, barcode devices and secure data flows. Read-only collection can be introduced before automated write-back. Indicative duration: two to four weeks.

04
MES Module Configuration

Build dispatch, tracking, quality, traceability, downtime, work-instruction and dashboard workflows based on the agreed scope. Indicative duration: three to six weeks.

05
Pilot Line and User Acceptance

Run the system on a representative line, reconcile MES results with existing records, test exception cases and collect operator and supervisor feedback. Indicative duration: two to four weeks.

06
Rollout, Training and Support

Deploy the validated configuration to additional lines, train users by role, monitor adoption and add modules or integrations according to the rollout roadmap.

Basic information

Frequently asked questions.

ERP manages business planning, purchasing, inventory, finance and high-level production orders. MES manages real-time execution on the shop floor. ERP defines what must be produced; MES dispatches the work, records what actually happened and sends confirmed output, material, quality and downtime information back to ERP.

ERP is essential for business planning but usually does not capture execution at machine, operation or event level. MES becomes useful when production teams depend on paper, spreadsheets or delayed manual updates to understand work-in-progress, downtime, quality and traceability.

Yes. A modular rollout is usually more manageable than attempting every MES function in the first release. A plant can begin with production tracking, dispatch, traceability, quality or downtime capture and add further modules once users and data have stabilised.

MES can record product genealogy, material batches, machines, operators, process parameters, inspection results, deviations and approvals. These records can support traceability and audit requirements, but the system alone does not guarantee certification. Processes, controls and evidence must be configured according to the organisation’s quality system.

Duration depends on the number of modules, production lines, machine connections and ERP integrations. A focused pilot can normally be completed faster than a plant-wide rollout. Tech4LYF establishes the pilot and rollout schedule after the scoping and integration assessment.

MES cost depends on the modules selected, number of work centres, machine connectivity, ERP integration, hardware, data migration, validation and support requirements. Tech4LYF provides an itemised estimate separating software, integration, devices, implementation, training and ongoing support after the scoping workshop.

Yes. Older machines can be connected through PLC tags, retrofit sensors, digital inputs, gateways or operator-assisted data entry. The appropriate method depends on the data required, machine condition, available signals and expected operational value.

MES can be deployed on-premise, in a private cloud or through a hybrid architecture. Plants with limited or unreliable internet connectivity can keep critical execution services on site while synchronising selected information with cloud or enterprise systems.

SCADA primarily supervises machines and industrial processes through live signals, alarms and controls. MES manages production execution across orders, materials, operators, quality and traceability. The two systems can work together, with SCADA or PLC data feeding production events into MES.

Yes. MES can exchange production orders, product and routing information, material requirements, completion status and actual consumption with Odoo, SAP, Oracle or a custom ERP through APIs, database interfaces, files or middleware.
