Chose Apache Subversion
I find Perforce to be a little more cumbersome to use than Subversion. And it is NOT free or open source.
Git is probably the biggest open source rival to Subversion. It's designed for distributed development, an environment I'm not very familiar with. I've only got some experience with it, and only as a user, and even that is limited. I had some trouble wrapping my mind around the …
New users of Perforce Helix can be up and running in less than thirty minutes. It is easy to use, but also very powerful. Bitbucket is slow, prone to outages, and (for large teams) requires a team of dedicated administrators. I've had request for information from Bitbucket that …
It's a relatively simple version control system so it works great for an individual or small team (less than 10 people). But if you have a medium to large team, especially one with members distributed over a large geographic area, or one where individuals need to be able to work "offline" without access to a central server, Apache Subversion will likely not be the best choice.
Also, if you're maintaining an open-source project where outside people will be interacting with your code repository, git is probably a better choice because it's becoming the de-facto standard these days and what most developers are familiar with.
If you are familiar with IBM Rational Suite products, RequisitePro will add up due to the synergy between other components. Beyond that, if your business is not structured to an adequate development methodology or lacks the degree of maturity or necessary resources, probably RequisitePro does not add much value. If you work with developers in the requirements analysis, they probably prefer to use an SVN repository.
While Perforce Helix is the best version control software out there, it can also be used to track your documentation, training videos and materials, and requirements. If you have strict compliance requirements, it can be used to ensure that those requirements are satisfied. Perforce Helix is incredibly flexible and can meet the needs of individual users as well as companies with thousands of users.
The branching mechanisms in Perforce allow for an enormous codebase to be duplicated into release versions weekly with little impact upon things such as the speed of queries against the version control.
Action triggers permit such things as automated builds of software versions, dynamic messaging when issues are identified either within or prior to a build process, and much more.
Locking provides the ability to prevent modifications of stable, tested versions in order to ensure validity when they are released.
Distributed development - I've never worked in an environment where distributed development (developers widely scattered geographically) was a factor, but that's why git exists.
Merging - Merging of code from one branch to another can be painful, especially if it's not done frequently. (On the other hand, doing merges is one of the reasons I get a nice salary, so I can't complain too much!)
Acceptance - Let's face it, git is what "all the cool kids are using." If you've got a bunch of developers fresh out of school, they'll probably know git and not Subversion.
Performance can be an issue. Make certain the server is sized properly
There is a large difference in capability of the Thick Client Version compared with the web based version. Make certain each job function has proper access to be able to do what is required of them.
Learning curve is not too steep, but would suggest having someone with experience setup the repository. Highly suggest getting a contractor to assist to get the repository up and running.
Perforce tends to feel backwards in how it approaches certain tasks, like branching and integrating - even once you figure out how it wants you to perform these tasks, you will likely forget when it comes around to the next time you need to do them again.
Perforce has a higher price tag, comparatively.
Perforce make some tasks very easy, and yet other tasks very difficult - it doesn't always seem to have found its target user's proficiency.
While there are interesting alternatives, such a GIT, Subversion has been a breath of fresh air compared to its predecessors like CVS or Microsoft Source Safe (now called Team Foundation Server). Its ease of use and high adoption rate is going to keep me using this product for years to come.
Most likely as it's one of the powerful tools in the organization. We needed this tool to track all the process related documentation and also to capture signatures.
We are fully committed to our use of Perforce. It works well within our organization and our desire to share our code base with our customers. Their support staff are responsive, inquisitive, and eager to improve their software. I feel like we have a direct line to their design/feature team as they often solicit our feedback.
Please keep in mind that this all has to do with you you customize the user interface. It becomes very easy to house all of your requirements, but it may and can make life difficult for you if you do not think ahead of how you want the app to work and house your data
With Perforce Helix, you can use it via the command line, via P4V, or any of the other APIs included with the product. It is extremely easy for new users to get up and running. Users of Perforce Helix only have to pull in the files of interest to them. Also, Perforce is very easy to script and integrate into your CI/CD pipeline. Streams allows you to have pinpoint control of your workflow, and P4Search is the absolute best--I wish Perforce (the company) would talk more about this. It is absolutely fabulous!
In our large environment, Perforce is rarely "down". We have regular maintenance windows and from time to time Perforce can feel a little slow, but its always available. Tech support has always worked with our engineers and IT department to make sure that any real performance or stability issues are addressed quickly.
IBM has good support and knowledge base. With the wealth of information on their site and the support desk, we were able to quickly resolve issues. It is smart to build up a COE and a group that manages the software otherwise it is quick to be able to lose the knowledge as team members are assigned different duties
I had two representatives from Perforce contact me after downloading it but never responded when I had questions. I also had a difficult time finding good training material for getting started. There is a lot of available support material when running into issues, though, because of how many large companies use it.
This rating is related to setting up an environment from an existing Perforce repository. Initial setup of Perforce as the repository for the company was done by a separate team long prior to my inception.
Git has become the new standard of version control, with its support for distributed design. As a tool to manage and control versions, Subversion does it well, but Git is the future.
IBM clearquest would the BEST option if you are looking for managing change requests, managing project workflows, generating reports on status of requests. The reason being: cost, cost and cost. It almost handles everything that you would need for your project including bug tracking unless you want something really fancy (like HP QC) with a higher cost that supports a wide variety of needs which you might need to evaluate based on your project needs. For example, if you would be really making use of all those additional features provided by HP Quality Center. To be honest it depends on your project size, the skills of team members and of course budget!
Git is great, I love Git. But it's not great for dealing with binary assets, even when using Git LFS. Locking is not as simple as on perforce. Git presents some problems on using for non-tech people it can get overwhelming and tech people have to come by and help.
IBM Rational ClearQuest has provided a workflow that works without unique software methodology. As a result we deliver complete software products to our clients in a 6 to 8 week development time frame.
As a result of our highly customized implementation, we have 8 resources supporting IBM Rational ClearQuest. Three of the resources are full time configuration management staff that administer and support the tool set and the other 5 are from the testing group that handle ClearQuest user support issues in addition to their testing duties.
