Manufacturing execution, explained without the jargon
Most people running a plant have never been told what an MES actually is, only that they need one. These guides start from the problem, not the acronym.
What is an MES? A plain-language guide for manufacturers
A Manufacturing Execution System (MES) connects the production plan in your ERP to what actually happens on the shop floor. Here is what an MES does, what falls outside its scope, and when your plant starts to need one.
Read the guide →Factory digitalisation: a sequence that works, not a list of technologies
Making Indonesia 4.0 puts digitalisation on the national agenda, but most projects stall at the dashboard. Here is the sequence that tends to succeed, why shop-floor data has to come first, and how to assess readiness.
Read the guide →Halal traceability on the shop floor: the evidence you have to be able to produce
A halal certificate covers a product. The claim has to hold for every batch. Here is the chain of evidence an SJPH audit follows, the three points where it usually breaks, and how a production system keeps it intact.
Read the guide →CPOB and computerised systems: what Indonesian GMP asks of digital production records
When batch records move from paper to a system, CPOB demands things paper never had to provide. Here are the ALCOA+ principles, what they mean on the shop floor, and where vendor responsibility ends.
Read the guide →MES vs ERP vs SCADA: what does each one actually do?
ERP holds the plan, SCADA monitors and controls the machines, and MES connects the two through the real production process. Here is how they differ, what each one owns, and why one cannot simply replace another.
Read the guide →MES vs MOM: a real difference, or just newer vocabulary?
MOM is the ISA-95 term for everything at Level 3. MES historically covered production execution alone. Here are the four MOM categories, why the distinction matters when buying, and where the words are now used interchangeably.
Read the guide →How to calculate OEE, with a worked example and the usual mistakes
OEE is Availability times Performance times Quality. Here is the formula, a full worked shift, why manually calculated OEE is almost always too high, and how to read the number properly.
Read the guide →Finite capacity scheduling: why the ERP schedule keeps getting rewritten
ERP builds schedules as though capacity were always free, which is why the sequence gets rebuilt on the shop floor. Here is what finite capacity scheduling means, the four scheduling strategies, and why tanks and pumps need different treatment.
Read the guide →ISA-95 explained: the five levels and where an MES sits
ISA-95 (IEC 62264) divides manufacturing into five levels, from the physical process up to business planning. Here is what each level does, why Level 3 is so often the empty one in a plant, and how the model helps connect IT with operations.
Read the guide →OPC UA vs MQTT: not a choice between two competitors
OPC UA carries meaning. MQTT carries messages efficiently. They solve different halves of the same problem, and most plants end up running both. Here is what each actually does and how to decide per connection.
Read the guide →ISA-88 vs ISA-95: two standards, two different questions
ISA-88 describes how a batch is made. ISA-95 describes how systems exchange information about manufacturing. They overlap in the equipment hierarchy, and that is where the confusion usually starts.
Read the guide →21 CFR Part 11 for manufacturers: what it demands of your systems
What 21 CFR Part 11 requires from electronic records and electronic signatures: attributable, tamper-evident, and independently verifiable. Here is what that looks like concretely in an MES audit trail.
Read the guide →Electronic batch records: what actually changes when the paper goes
An EBR is not a scanned batch record. The value is in refusing bad data at entry and enabling review by exception. Here is what an EBR contains, why review by exception is the real return, and where implementations go wrong.
Read the guide →Choosing MES software: the questions a presentation cannot answer
Every MES vendor can run a smooth demo. What separates them is how the system holds up when your process changes. Here are the questions that have to be proved, the costs that rarely appear in a proposal, and the early signs an implementation will go badly.
Read the guide →Building your own MES vs buying one: an honest comparison
Building an MES in-house starts well and gets expensive in year three. Here is what actually drives the cost, the narrow cases where building genuinely wins, and how to calculate a comparison that survives contact with reality.
Read the guide →Why we built VECHR MES
VECHR was born on real plant floors, from one complaint that kept coming back: existing MES software was too rigid, and every customization turned into a fight against the platform. This is the reasoning behind building an adaptive one instead.
