The solution was set up internally, most likely. 

It took two weeks for two people to deploy Codebeamer in our organization.

We follow a deployment strategy. Our first rollout happened within a week of trials.

We installed codeBeamer and we just enabled and configured the plugins. We tested it on guest servers and we rolled it out immediately within a week. 

Typically, two to three people are more than enough for deployment. One will be the system administrator, another will be the plugin developer and plugin manager, and the third will be the template configurator.

A little bit of maintenance is required, but not much. Specifically maintaining the databases, maintaining the artifacts, managing the access rules, etc. Typically, the admin activities need to be maintained.

We implemented this solution in-house, alone.
