A Gantt chart in the Enterprise Architecture Workspace is a visual representation of the Technology Portfolio Management (TPM) and Technology Reference Model (TRM) timelines of business applications, and their associated application services like software products and hardware models.  
The TPM and TRM application timelines can be viewed in the following timeline views, in the Gantt chart.

* Day
* Week
* Month
* Quarter
* Year

  For Technology Portfolio Management (TPM), the business applications and their related application services (associated hardware models and software products) are displayed in a hierarchical structure. The corresponding timelines of the application services are displayed as bars on the Gantt chart.

  For Technology Reference Model (TRM), the application services (hardware models and software products) are displayed in a hierarchical structure, similar to the TPM view. The corresponding lifecycle timelines of the application services are displayed as bars on the Gantt chart. It also displays the data for lifecycles with wild card versions. The TRM wildcard version ends with a '\*'.
