DOORS is not the easiest to set up. It is straightforward if you're a good admin.
Once it is set up, it's very powerful and user-friendly. Just like any tool, you have to get the training in it. Even Excel and PowerPoint can be complex for a person who isn't familiar with them.

The initial setup is medium in complexity. It is not straightforward. The admin console itself is a little tricky to understand within the whole licensing model and user access control.

I would rate the initial setup a four point five out of five.

The product's initial setup phase was not too difficult, so I could say that it was medium when it came to the difficulty level.

The solution is deployed on an on-premises model.

I have to put a client on my computer, and I just have to follow the directions. It's not as easy as just going to a SharePoint site and then just running it. However, it's not too complex. For the first time that you do it, you have to go do some special things with loading a client and all that good stuff. That said, once that's done, it's pretty much just click and play if you want to call it that. That said, the initial setup takes a little bit of time. It does take a few hours to deploy it. 

The initial setup was quite complex. Due to the complexity of the setup, we required the assistance of the IBM partners. 

 The configuration was complex and it took a lot of time to configure and install properly. This was the largest problem we had with this solution.

The deployment method we used was on-premises and took one to two months, but we were resolving some problems four months after the installation. 

We were working with the external partners from IBM and we had two people from the IT department on the project. For the maintenance, we have one employee working full-time, half of the time working on maintaining the system.

For new features and the implementation of the upgrades, it is project-based and we would go through the IBM external partners. 

When everything works well it is just to maintain.

The tool's deployment is easy, but you need some training in it. We require specialized training that lasts about a month to fully understand the platform. The deployment process involved providing and implementing the solution for an American automotive manufacturing company in North America. Our role was to implement the solution as part of the project.

Setting up IBM Rational DOORS Next Generation is complex. You have to set up a Jazz Team Server and you have to set up the database. Depending on which tools you use, which database, which operating system: if it's Windows or Linux, etc., it sometimes requires complicated activities to install. Depending on what you install on the Jazz platform, you need the Jazz Team Server, so on the cloud, it's not really working. It's good to have a HTTP proxy in between.

It's a little bit difficult to install it. Normally, it takes half a day to complete the installation if it's a very simple installation. If it's a complex installation, it could take two to three days.

The initial setup is very straightforward. There is a wizard that installs the requirements and takes care of everything for you. The set up is really simple. However, if you want to deploy it to an enterprise, it could be tricky.

I do not do back-end administration of DNG, so I cannot comment on this except to say, given the amount of problems I have encountered, it must be a complex and error-prone.

It's slightly more complex than a Tomcat configuration due to a WAS and multi-server Jazz application configuration.

The configuration involves customizing attributes and the deployment is not easy.

It was easy.
