PLM (Product Lifecyle Management)

PLM, also referred to as ALM, serves to manage all information concerning a facility, across its whole life cycle. This approach enables to...


A complex infrastructure such as a nuclear power plant represents over 50,000 documents, 100,000 requirements, 500,000 elementary components and a huge amount of data. Managing all these data is the purpose of PLM, especially for facilities with a lifetime that can exceed 50 years. This approach ensures vertical continuity (between engineering teams, supply chain etc.) and horizontal continuity (between design, construction and operation phases) throughout the lifecycle of an infrastructure. The PLM is a digital engineering tool and is part of the system engineering. 

PLM (Product Lifecycle Management), or ALM (Asset Lifecycle Management) brings together a set of concepts, methods and collaborative software solutions, enabling to manage all the information concerning a facility throughout its lifetime.

To ensure the uniformity and quality of data, made complex by the existence of multiple stakeholders inside and outside the company, PLM enables to switch from a "document-centric" operation to a "data-centric" operation in collaborative mode. This approach enables therefore to prevent risks of inconsistency for better project management in terms of deadlines, risks and costs.

PLM has been used in sectors such as Defence & Aerospace, Aviation, Automotive, mechanical and electronic engineering for over 15 years. It has largely demonstrated its usefulness in product management. It was more recently adopted in complex infrastructures such as nuclear but is widespread today and tending to be deployed alongside BIM.

Our approach for PLM

In terms of new constructions and the management of existing facilities, Assystem firstly tries to clearly define user requirements and the associated use cases. This approach is carried out consistently with Systems engineering processes. We guarantee the convergence of PLM and BIM processes, through the consistency of data models.

As Assystem is not limited to a specific brand of software solutions, we can implement PLM solutions progressively through Agile methods in three phases: Scoping workshops, Development and Use.

We deploy these solutions for our own needs, especially on projects where we deliver project supervision.

Assystem also supports clients in their implementation of PLM solutions, whether in the scoping phases or implementation, with special focus on suitable change management.
