GitHub vs. OpenText Dimensions CM

GitHub is an easy to go tool when it comes to Version Controlling, CI/CD workflows, Integration with third party softwares. It's effective for any level of CI/CD implementation you would like to. Also the the cost of product is also very competitive and affordable. As of now GitHub lacks capabilities when it comes to detailed project management in comparison to tools like Jira, but overall its value for money.

Serena CM is well suited to highly controlled, audited, and process driven environments. It will allow strict segregation of duties, and change traceability. If implemented correctly it will help you quickly build trusts with your auditors. It is also well suited to environments that require constant branching and merging. Due to the complexity of the product and learning curve for your development and operations team it may be overkill in a small shop with loose rules

• Version control: GitHub provides a powerful and flexible Git-based version control system that allows teams to track changes to their code over time, collaborate on code with others, and maintain a history of their work.
• Code review: GitHub's pull request system enables teams to review code changes, discuss suggestions and merge changes in a central location. This makes it easier to catch bugs and ensure that code quality remains high.
• Collaboration: GitHub provides a variety of collaboration tools to help teams work together effectively, including issue tracking, project management, and wikis.

• Code Promotion: Dimensions CM allows supervisors to control changes to code, in that they delegate requests to developers, and act as a gatekeeper prior to promoting to the next environment. This functionality is configurable so you can set up a workflow that best fits the structure and requirements of your own company.
• Code Repository for changes and versioning: Code can be checked out by item or by synchronizing folders. Code revisions can be compared against other revisions or work files. Item histories show which developers made which modifications, and which supervisor and operations personnel were involved in assigning the request and promoting the code to each environment. Additionally a pedigree will show a stream diagram which graphically displays branches and merges.
• Deployment: Serena Change Management offers help automating deployment including integrations with SVN and Jenkins. Its newer versions also have a powerful graphical deployment automation tool (Serena Deployment Automation- SDA). It comes with a certain amount of licenses built-in. If you have a many nodes to deploy to there will be separate licensing costs for that.

• Not an easy tool for beginners. Prior command-line experience is expected to get started with GitHub efficiently.
• Unlike other source control platforms GitHub is a little confusing. With no proper GUI tool its hard to understand the source code version/history.
• Working with larger files can be tricky. For file sizes above 100MB, GitHub expects the developer to use different commands (lfs).
• While using the web version of GitHub, it has some restrictions on the number of files that can be uploaded at once. Recommended action is to use the command-line utility to add and push files into the repository.

• The only major negative that I have encountered with Serena CM product is that the very power and flexibility of the tool means there is a risk that you will make a mess of things. In other words it gives you plenty of rope to tangle yourself with. I recommend careful, well thought out deployments implementing the built in roles and workflows that can be turned on and configured, using a consistent methodology.
• My experience with the Serena help desk support has not been impressive. Though reasonably polite and diligent, the technicians were well trained, and often gave bad advise and terrible scripts. On several occasions I had to rewrite scripts they have me; if I had run them as provided they would have caused even more difficulties than the problem I was trying to solve. I speak of the support in the past tense because I conditioned myself not to call them, it was usually just easier to solve nay problems my self. They do have a good account management team though, and for any major issues you can go thru them.

GitHub's ease of use and continued investment into the Developer Experience have made it the de facto tool for our engineers to manage software changes. With new features that continue to come out, we have been able to consolidate several other SaaS solutions and reduce the number of tools required for each engineer to perform their job responsibilities.

GitHub is a clean and modern interface. The underlying integrations make it smooth to couple tasks, projects, pull requests and other business functions together. The insights and reporting is really strong and is getting better with every release. GitHub's PR tooling is strong for being web based, i do believe a better code editor would rival having to pull merge conflicts into local IDE.

There are a ton of resources and tutorials for GitHub online. The sheer number of people who use GitHub ensures that someone has the exact answer you are looking for. The docs on GitHub itself are very thorough as well. You will often find an official doc along with the hundreds of independent tutorials that answers your question, which is unusual for most online services.

While I don't have very much experience with these 2 solutions, they're two of the most popular alternatives to GitHub. Bitbucket is from Atlassian, which may make sense for a team that is already using other Atlassian tools like Jira, Confluence, and Trello, as their integration will likely be much tighter. Gitlab on the other hand has a reputation as a very capable GitHub replacement with some features that are not available on GitHub like firewall tools.

Serena CM is superior to Microsoft Team Foundation Server (TFS) in overall functionality, but does not have very good native integration with Microsoft. Therefore in a Microsoft centric shop with no audit needs ,TFS would be better. Otherwise I would choose Serena CM

• Team collaboration significantly improved as everything is clearly logged and maintained.
• Maintaining a good overview of items will be delivered wrt the roadmap for example.
• Knowledge management and tracking. Over time a lot of tickets, issues and comments are logged. GitHub is a great asset to go back and review why x was y.
