IBM Rational ClearQuest is a change management software that improves developer productivity without ignoring developer processes, methodologies, and tools.
Therefore, IBM Clear Quest is a database workflow and production system used in the software development lifecycle (SDL) that can be customized. Recent versions have adopted a new consumption model that accounts for how developers use DevOps in the SDL. In addition, Rational ClearQuest is more easily integrated with other IBM tools offering better documentation.
IBM ClearCase allows developers to use two configurations and management models. These are unified Change Management (UCM) and the base ClearCase model. While UCM can be described as using an out-of-the-box model, base ClearCase gives a basic infrastructure. However, both approaches allow a developer to meet a wide variety of professional tools during SDL.
For instance, ClearCase accommodates big binary files and big repository sizes. Furthermore, a developer can branch, label, and version directories. All this is possible because ClearCase is based on a Multiversion File System (MVFS) that has the advantage of being a virtual file system. Therefore, ClearCase allows a developer to identify and display specific versions of the stored data with which they work. Furthermore, ClearCase allows dynamic views that expose arbitrary links between local and remote files.
In conclusion, due to changing business needs, IBM Rational ClearQuest is preferred due to its workflow and change management. It is comparatively easier to use, install, and manage compared to IBM ClearCase. As an organization grows, it can take advantage of ClearQuest’s scalable and multiplatform support system.
Being a fully customizable model, ClearQuest offers better traceability and defect visibility, making it the most appropriate plan for today’s business needs.
