ALM (Application Lifecycle Management)
Application Lifecycle Management (ALM) is the discipline and toolset for managing the full lifecycle of a software application — requirements capture, development, testing, release, and maintenance. In the context of PLM, ALM becomes relevant as modern engineered products (vehicles, medical devices, industrial equipment) contain increasing amounts of embedded software. ALM tools like PTC Codebeamer, Siemens Polarion, and IBM Engineering Lifecycle Management bridge software development practices (agile, CI/CD) with hardware-oriented PLM processes (change orders, configurations, regulatory traceability).
Why it matters
Modern products are software-intensive. A car, a pacemaker, a robot, a wind turbine all carry embedded software whose lifecycle does not align with the physical lifecycle — the firmware updates monthly, the part it runs on updates yearly. PLM owns the physical configuration; ALM owns the software configuration; the bridge between them determines whether the as-shipped state of any unit is recoverable end-to-end or whether it stops at the metal.
