MES study plan

Define MES and map its functional scope against ERP, SCADA, PLC, and LIMS layers, writing a one-paragraph boundary statement for each interface

Diagram the ISA-95 hierarchy levels 0 through 4 and label where MES sits, listing the data exchanged at each boundary

Trace a work order from creation through release, execution, and closure, annotating the state transitions and the system of record at each step

Explain core production operations objects (work order, operation, routing, BOM, resource) and how they relate in an MES data model

Compare dispatch, scheduling, and sequencing strategies and select the appropriate one for three described shop-floor scenarios

Calculate OEE from shift data including availability, performance, and quality factors, and identify the top loss category

Describe how WIP tracking, operation confirmation, and labor/equipment time capture feed production reporting

Explain how production order changes (split, merge, rework, scrap) are handled and what audit trail each requires

Design a sampling and inspection plan for an in-process and a final inspection point, specifying sample size rationale, specification limits, and disposition rules

Map the nonconformance workflow from detection through hold, disposition, CAPA linkage, and closure, listing required data fields at each stage

Describe how MES enforces material genealogy and traceability for lot, serial, and component consumption, including forward and backward trace queries

Explain inventory transactions (receipt, issue, transfer, cycle count, adjustment) and how they reconcile to production consumption

Configure a material master and location hierarchy exercise covering lot control, shelf life, and status management

Differentiate preventive, predictive, and corrective maintenance strategies and identify which MES data triggers each

Describe how equipment states, downtime reason codes, and mean time between failures are captured and used

Explain tooling and spare parts tracking and how maintenance work orders interact with production scheduling

Classify data collection methods (manual entry, barcode, RFID, OPC UA, PLC tags, machine vision) by latency, accuracy, and cost, and justify a choice for four described use cases

Design an integration map between MES, ERP, historian, and shop-floor devices, naming the protocol and the master system for each data entity

Explain message patterns (request/reply, publish/subscribe, queuing) and how to handle duplicate, late, and out-of-order events

Describe MES architecture options (on-premise, hybrid, cloud) and the configuration objects that differ across environments

Explain user role, permission, and electronic signature configuration and how segregation of duties is enforced

Compare GMP validation lifecycle requirements (URS, IQ, OQ, PQ, traceability matrix) with a lighter non-regulated rollout and state which deliverables each needs

Identify 21 CFR Part 11 and EU Annex 11 themes including audit trails, data integrity ALCOA+ principles, and record retention

Describe change control for MES configuration and the evidence needed to demonstrate a validated state after change

Select KPIs for throughput, yield, cycle time, and quality, and define each with formula, data source, and review cadence

Design a shift and trend report layout that supports a daily tier meeting and an improvement review

Apply a structured problem-solving method (DMAIC or A3) to one OEE or quality loss and state the data the MES must supply

Explain how reporting access, data retention, and audit trail review are governed under compliance requirements

Reconstruct the full domain map from memory and rate confidence per domain to target remaining weak areas

Complete a timed 100-question mixed practice set and analyze every miss by domain and error type

Review flagged weak topics and rewrite personal summary notes for each

Simulate explaining the end-to-end MES data flow from sensor to report to a non-technical stakeholder
