Keysight Technologies (KEYS) shares moved higher on Thursday after the company joined the Siemens Digital Industries Software Technology Partner Program.KEYS rose 1.64% to $329.30 and held near session highs. The move followed a volatile morning, while the stock consolidated around the $329 level.
Keysight Technologies, Inc., KEYS
The partnership gives Siemens customers access to Keysight Eggplant Test, an AI-driven test automation solution. The tool helps validate digital engineering systems and product lifecycle management environments. It also supports testing across enterprise applications before companies move updates into production.
Keysight said the collaboration targets manufacturers that rely on complex software systems. These companies use digital platforms to manage design, engineering, and production workflows. However, manual testing can slow upgrades, integrations, and system checks across large PLM environments.
Keysight Stock Gains After Siemens Program Entry
Keysight joined the Siemens Digital Industries Software Technology Partner Program to expand access to Eggplant Test. The solution uses AI-driven test design and generation for enterprise software validation. Through the program, Siemens customers can use it with Teamcenter software.
Teamcenter supports product lifecycle management across engineering and manufacturing operations. Therefore, the partnership connects Keysight’s test automation tools with a major industrial software platform. It also gives manufacturers another way to reduce software risk before deployment.
Siemens Partnership Targets PLM Testing Pressure
Manufacturers face rising pressure to shorten product development cycles. At the same time, software-driven products have become more complex and harder to validate. This creates pressure on engineering teams that rely on PLM platforms.
Manual testing can miss workflow issues and integration problems. It can also delay software upgrades when teams handle large enterprise systems. As a result, automated testing has become more relevant for manufacturers managing digital operations.
Keysight Eggplant Test helps validate workflows, integrations, and system performance. The tool supports test design and generation across enterprise applications. Siemens customers can use it to check PLM environments before production releases.
Keysight Expands Software Testing Role
Keysight has built its business around design, emulation, and test solutions. The company serves customers in communications, industrial automation, aerospace, defense, automotive, semiconductors, and general electronics. Its tools help engineers develop and deploy products with lower operational risk.
The Siemens partnership extends Keysight’s role in software quality testing. It places Eggplant Test inside a broader digital engineering ecosystem. In addition, it connects Keysight with manufacturers already using Siemens software tools.
Keysight said PLM environments require reliable validation as complexity increases. Gareth Smith, Software Quality Engineering General Manager at Keysight, said engineers can reduce undetected issues during upgrades and integrations. He added that the solution helps maintain performance and reliability through the product lifecycle.
The collaboration gives customers a structured path to test PLM processes at scale. It also addresses bottlenecks linked to manual testing and complex enterprise workflows. For Keysight, the program adds another channel for its AI-driven test automation offering.
