Question 1

What is Manufacturing Execution System (MES) Software?

Accepted Answer

Manufacturing execution system (MES) software helps manufacturers execute production plans by implementing work orders on the shop floor. While enterprise resource planning (ERP) systems help manage production schedules, MES software manages manufacturing operations. Sometimes referred to as manufacturing operations management software, MES allows manufacturers to track production cycles to identify bottlenecks, monitor quality in real time, and measure shop floor performance. 
 MES is a critical component of industry 4.0 which aims to improve digital transformation by automating manufacturing processes. According to research by Manufacturing Enterprise Solutions Association (MESA) International, MES is an essential part of a manufacturer’s software ecosystem. 
 What Does MES Stand For? 
 MES stands for manufacturing execution systems, which describes how this software differs from ERP for manufacturing. MES manages the execution of production orders created in ERP systems. 
 What Types of Manufacturing Execution System (MES) Software Exist? 
 MES types vary depending on how the software is delivered and the industry focus of the solution. 
 Industry-specific or agnostic 
 MES functionality depends on the type of manufacturing the solution is being used for. The main manufacturing categories are discrete (medical devices, process pharmaceuticals, and engineering) to order. Mixed-mode ERP combines two or all of these manufacturing categories. For instance, the aerospace industry requires discrete ERP for parts and ETO ERP to assemble an aircraft.  
 Standalone or part of a suite 
 MES is usually sold and used as a standalone software solution but can also be deployed as part of a more extensive manufacturing suite that generally includes other software such as ERP systems and quality management systems.

Question 2

What are the Common Features of Manufacturing Execution System (MES) Software?

Accepted Answer

The following are some core features within MES software that can help users improve quality and increase productivity: 
 Resource allocation: Production requires raw materials, ingredients, and components to manufacture finished products, as well as labor and equipment. All these resources are allocated to production orders by MES systems based on the quantities required and their availability.  
 Shop floor management: Dispatching employees on the factory floor is essential in any manufacturing process. Using resource planning, MES assigns technicians to equipment and workstations and ensures everyone knows what to do and when by creating clear work instructions. 
 Production scheduling: While the production process is defined in advance, production orders may change either because manufacturers adjust their priorities or because of issues such as defective equipment and lack of inventory.  
 Production monitoring: MES tracks production output and product quality while also focusing on traceability across all production stages. Monitoring should provide real-time data so production and quality managers quickly identify issues that may negatively impact production, equipment, and employees. 
 Data collection and analysis: MES collects production data which is transferred to other information systems such as business intelligence to analyze manufacturing performance, production costs, and equipment efficiency.

Question 3

What are the Benefits of Manufacturing Execution System (MES) Software?

Accepted Answer

The main benefits of MES are: 
 Production visibility: MES provides visibility into all stages of the production process with real-time updates on what is being manufactured, the estimated time to completion, and who is in charge.  
 Reduced costs: Better visibility helps manufacturers avoid costly errors that may compromise an entire production batch if not detected early. It also allows other departments like accounting to track production costs.  
 Increased productivity: By using MES, shop floor employees know precisely what they need to do and how. Also, production managers can optimize equipment use through planning, thus reducing downtimes, which reduces the wait time between production cycles. 
 Improved overall equipment effectiveness (OEE): OEE is a global standard used to measure manufacturing productivity. It is often used as a benchmark to compare a manufacturer's performance with its peers in the same industry. MES helps improve OEE scores, a significant competitive advantage for manufacturers.
