Difficult to use, not efficient, but stable

We are using IBM Rational ClearCase in Peru at two large banks for a code repository. However, it is not meant to be used as a repository 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. I have…

Users must go through a lot of steps to properly manipulate this solution, which can interrupt workflows and cause unnecessary downtime

We are required to use this tool by DO-178 guidance. We have to use a configuration management tool and this is the one we have been using. People see this tool more like a constraint than a benefit. Users really have to know how to use this tool and how to set the baseline functionalities for their case. The user must go through a lot of steps to properly manipulate this solution, which can interrupt workflows and cause unnecessary downtime. Synergy requires user training and development. It's not user-friendly. You have to perform a lot of manipulations; it's a bit archaic. Some people are reluctant to use this tool because they are familiar with and proficient in using Windows Explorer to navigate through directories and use WinZip to archive data. It is not a very good tool for document management. I would rate this solution a three out of ten because it's an old tool. It was a good tool 15 years ago. To get a ten out of ten I would need to see a more integrated user-friendly tool and it should be competitively priced as it is it's too expensive. I don't recommend using it because it's obsolete.

Quotes from Members

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

Pros

"The features allowed us to meet requirements for SOX and set a centralized guideline for our development teams."

"IBM Rational ClearCase is a stable solution, and I have not had any difficulty with reliability."

"ClearCase integrates well with other engineering tools and frameworks such as the Eclipse environment."

"Therefore when we started using ClearCase, it was like a miracle."

"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."

"I really appreciate the MultiSite feature; it is important to us due to the global nature of our company, as my team supports developers using ClearCase in at least ten locations worldwide."

"What I like most is that it is very stable."

"Managing source code, tracking modifications, and being able to analyze evolutions of source code are the most valuable features."

Cons

"Customer service is mediocre. Technical support is mediocre."

"This is an expensive product and the price could be reduced."

"Look for a more modern product. Your suppliers and developers will be happier."

"The solution's UI is slow compared to other tools. It is an old tool."

"IBM's support of ClearCase is slipping."

"The protection needs to be improved."

"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."

"I'd like to see more integration with respect to requirement management, though this is not possible with this Synergy solution. I know that PTC enables this feature as well as Polarion. We need to have full trustworthiness and accountability in knowing that the tool will track every modification from specification through to the source code, with Synergy this isn't possible. The solution requires additional tools like rectify, desktop system solutions, to enable trustability between requirements, from one specification to another."

"I don't recommend using it because it's obsolete."

Pricing and Cost Advice

"This is a very expensive product."

"IBM Rational ClearCase, like any other IBM tool, is expensive."
