This chapter is a collection of concepts that are used in the Lifecycle Twin application.


A portfolio is a collection of sites. A portfolio can have multiple locations (campuses) that have at least one site. The access to at least one portfolio is required to use the Lifecycle Twin application.


A site is a representation of the company with a real address. A site can either be a single building or a campus with multiple buildings. A single company can have multiple sites.


A company is considered the top-level management unit, for example Siemens. Inside the company, all the administrative actions are held. The membership of a user in one or more companies is required to use the Lifecycle Twin application.


A user is a person that is a member of at least one company and has been granted access to at least one portfolio by the Administrator of a company, Siemens, or a Third Party at Customer’s request and authorization. A user needs an Account to access the Lifecycle Twin application.

User group

User groups provide a specific level of permissions inside a company. A user group can only contain multiple user roles.


User roles are a predefined set of permissions for an application. In Lifecycle Twin, two types of roles exist: standard platform roles and company-specific user roles. The two standard platform roles are Administrator and User. To provide specific accesses, the Administrator can create company-specific user roles. User roles cannot be given directly to a user, but are managed by creating user groups for each of the available user roles.
