The risks can include the following: * Security risks: The software might be exposed to security issues. * Delivery risks: There might not be sufficient knowledge on how to support the software. * Legal risks: A business application might use the software in illegal ways. {#eaw-managing-the-technology-portfolio__ul_ovt_2nr_dcc} You must define the standards for the software that is to be used and the software versions that are permitted for use in your organization. Also, you need a way to explore when a non-permitted software is being used within the organization and in which business applications. You can use the TRM module in the Enterprise Architecture Workspace to perform the following: * View a list of all available TRM products. You can also view the list of TRM products grouped by product category. * Request a TRM product * Request a TRM product lifecycle * Create a TRM product * Create a TRM product lifecycle * Approve or reject TRM product and product lifecycle requests. {#eaw-managing-the-technology-portfolio__ul_jcm_3nr_dcc} Using the TRM module, you can manage the standards of the technology and set the right guardrail for technology usage. Setting the standards can improve the technical debt, security posture and save costs for the organization. You can also assign an owner to a TRM category, to ensure clear accountability and improved governance standards. The owner is responsible for maintaining consistent technology compliance standards for that TRM category. ## TRM Product Lifecycle {#eaw-managing-the-technology-portfolio__section_okg_rxq_dcc} Each product in the TRM library is associated with a set of life-cycle phases with a start and end date. The life-cycle phases could be approved, unapproved, approved with constraints, Divest, and evaluation. The TPM home page fetches all the business applications that are being used in your organization. It helps to review the status of the software that is being used. You can understand if any business application is using the software that is not part of the TRM or a software version that is not approved for production. For more information, see [TRM lifecycle timelines on Gantt chart](https://servicenow-prod.fluidtopics.net/pdLeuK8cDHYHPh0YB3M_DA "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 ‘*’."). The TRM module uses a similar module to TPM to search in the TRM library. You can view the software that is part of the TRM library, and initiate a request to add the software or software version to the TRM library. You can also use the TRM with the Software Asset Management (SAM) plugin. This plugin helps you to fetch or select the products and versions for the TRM library. You can also define your own software products when the Software Asset Management integration module isn't available for your instance.
