Our project charter is a method of project management that encompasses the entirety of the project life cycle of our customers, with a method specifically developed for the business activities of high-risk sites (including nuclear, defence, oil & gas, or industry facilities). The goal is cost control, quality control and adherence to timelines in the very constrained environments that involve the protection of high-risk sites.

Our methodology

Created to bring you the perfect solution
Baumert milestones or "JBx" track the status of each Baumert project.
The establishment of these milestones, from JB1 "Project launch" to JB8 "REX integration" and the performance measurement associated with each of them, lie at the core of the project development charter.
This charter is not only the repository of Baumert's know-how and experience in project management, but also provides a common language throughout the company, facilitating both communication and internal and external correspondence with our customers.
