About
Plex Systems is a cloud-based manufacturing ERP (Enterprise Resource Planning) and manufacturing execution system (MES) platform designed specifically for discrete and process manufacturers — providing production management, quality control, supply chain visibility, inventory management, and shop floor operations tracking in a single cloud platform. Founded in 1995 and headquartered in Troy, Michigan, Plex was acquired by Rockwell Automation in 2021 for $2.2 billion, becoming the software cornerstone of Rockwell's "The Connected Enterprise" smart manufacturing strategy.\n\nPlex's manufacturing cloud platform connects the production floor to the front office — tracking work orders, machine performance, quality inspections, lot traceability, and labor hours in real time. The MES capabilities provide production supervisors with live visibility into each workstation's throughput, scrap rates, and downtime, while the ERP layer handles procurement, inventory, shipping, and financial integration. The platform is used heavily in automotive supply chain manufacturing, food and beverage processing, and industrial manufacturing.\n\nIn 2025, Plex operates within Rockwell Automation (NYSE: ROK) as part of the Software and Control segment, integrating with Rockwell's industrial automation hardware (PLCs, drives, HMIs) and Factorytalk analytics platform. The manufacturing ERP market competes with SAP S/4HANA (manufacturing modules), Oracle Manufacturing Cloud, Infor CloudSuite Industrial, and specialized MES vendors. Plex's 2025 strategy emphasizes its integration with Rockwell's Logix control systems for closed-loop quality management, expanding in the food and beverage vertical, and growing its analytics capabilities for OEE (Overall Equipment Effectiveness) optimization.

About
International Business Machines Corporation (IBM) is an Armonk, New York-based global technology and consulting company — publicly traded on the New York Stock Exchange (NYSE: IBM) as an S&P 500 component — providing hybrid cloud infrastructure, artificial intelligence software, and enterprise IT consulting through approximately 270,300 employees in 170 countries with $62.8 billion in annual revenue. Founded on June 16, 1911, as Computing-Tabulating-Recording Company through a merger orchestrated by financier Charles Ranlett Flint, renamed IBM in 1924 under Thomas Watson Sr., IBM has undergone multiple strategic transformations over its 110+ year history: building the System/360 mainframe platform (1964), launching the IBM PC (1981), selling the PC division to Lenovo (2005, $1.75B), and completing the $34 billion Red Hat acquisition (2019) that repositioned IBM as a hybrid cloud platform company. CEO Arvind Krishna (appointed April 2020) has focused IBM's strategy on three areas: hybrid cloud (powered by Red Hat OpenShift, the enterprise Kubernetes platform), AI (the watsonx platform for enterprise AI model development and deployment), and enterprise consulting. Under Krishna, IBM recorded $12.7 billion in free cash flow in 2024 (a company record), surpassed $6 billion in generative AI bookings since June 2023, and saw the stock price double — trading at all-time highs through 2024-2025. IBM announced the DataStax acquisition in 2025 to deepen watsonx's data layer with AstraDB (vector database for AI applications), DataStax Enterprise (Apache Cassandra), and Langflow (low-code AI agent development).
