Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I find GitHub very user friendly."
"The features that I have found most valuable are that it can support you for most of the road map and it can automate some tasks which works really well with collaboration with the teams. They are really interested in how they organize the history of the code itself which is good."
"GitHub is pure or open-source; you can access it anywhere. You can have a lot of collateral information. You can make the changes and do the reviews from one place."
"Even if I'm not in the office, I can access and work on my code from anywhere with my account credentials."
"GitHub has improved the productivity of my team by simplifying code merging and enabling effective branching strategies."
"I find GitHub's pull request strategies and GitHub Actions to be very valuable."
"I use this solution to store my code in a repository so we can manage version control which is useful."
"The solution is scalable."
"IBM Rational ClearCase is a stable solution. I have not had any difficulty with reliability."
"The tool had features similar to Git for version control. It offered branching and merging capabilities, providing better control over code management. Integration was possible with other tools, including some change management tools. The overall process was normal."
"ClearCase integrates well with other engineering tools and frameworks such as the Eclipse environment."
 

Cons

"The product must document the CI/CD process more."
"The initial setup requires heavy documentation which can be challenging for new developers."
"If something has to be moved into approvals, and if they don't approve it in a few hours, then they should move the approval request to some other user, or they should have a way to escalate it."
"We face issues with synchronization while working with teams."
"It would be useful to have tutorial videos within the GitHub dashboard."
"There is a bit of a learning curve."
"From the recruiting standpoint, I would like to see email IDs and phone numbers and a brief introduction about their profile."
"The ticketing system is not working."
"I have found it very difficult to understand many functionalities in IBM Rational ClearCase. We have had many problems and it is not user-friendly."
"The solution's UI is slow compared to other tools. It is an old tool."
"The protection needs to be improved."
 

Pricing and Cost Advice

"We pay a licensing fee for GitHub, which could be cheaper."
"There are no licensing fees for the features that we use."
"Regarding pricing, I'd rate it eight out of ten. It's decent and not too expensive, and small businesses can also afford it. With AWS taking CodeCommit out of the market, I don't see many competitors for small companies in terms of GitHub."
"We pay a subscription-based yearly licensing fee for the solution."
"The product is reasonably priced."
"GitHub is an open-source product, but when using the free-to-use version, anyone can see the code we're working on."
"The private repositories are free, which is very good."
"The price of this solution is reasonable."
"This is a very expensive product."
"IBM Rational ClearCase, like any other IBM tool, is expensive."
