key outcomes you should research

You'll want to know how the MES you're looking at handles each of the following areas.  Ask pointed questions and see if they can back it up with examples of how they've done this for other companies.  

• real-time visibility: Gain complete oversight of production processes, including work-in -progress (WIP), machine utilization, and labor allocation.

• data-driven decision-making: Leverage advanced analytics and reporting to identify trends, bottlenecks, and improvement opportunities.

• streamlined operations: Optimize production scheduling, inventory management, and quality control processes for maximum efficiency.

• empowered workforce: Provide shop floor workers with intuitive tools and real-time information to enhance productivity.

• flexibility and scalability: Choose software that can adapt to your changing business needs and grow with your organization.

• robust integration capabilities: Ensure seamless connectivity between your MES and ERP.

Many solutions offer a limited set of features based on earlier versions of their product that had an area of expertise (inventory is a great example), forcing manufacturers to rely on multiple systems to manage their operations.  A truly effective platform should address the diverse needs of your manufacturing team.
