| Author info | Rating | Review Summary |
|---|---|---|
| Operation manager at OpenCage | 5.0 | I value 3SL Cradle's flexibility for managing service project requirements, noting its stability and scalability despite complex setup. I recommend it for specification, but desire better SysML support and full web access in the future. |
| Systems Engineer at a comms service provider with 501-1,000 employees | 4.5 | I find Cradle highly configurable, offering excellent bi-directional traceability and a comprehensive systems engineering suite. However, it lacks crucial SysML and DoDAF modeling notations for my work, despite having no deployment or stability issues. |
| Systems Engineering Specialist at XMobots | 3.5 | 3SL Cradle is user-friendly for small projects, increasing our efficiency by 25%. While global support is consistent, improvements are needed in specific areas. We explored alternatives like Jira but found Cradle met our needs better despite some support limitations. |

I mainly use 3SL Cradle to manage the requirements from service projects.
3SL Cradle's most valuable feature is its flexibility in managing all your needs immediately.
3SL Cradle could be improved with better support for SysML functionalities. In the next release, I would like 3SL Cradle to be 100% accessible in a web browser.
I've been using 3SL Cradle for six months.
3SL Cradle is very stable.
3SL Cradle is scalable.
3SL Cradle's technical support is very fast and helpful.
3SL Cradle is very flexible, so you have a good level of parameters that are necessary to configure first, which is not so easy.
I would recommend 3SL Cradle for users who prioritize a good specification for their project over good SysML support. I would give 3SL Cradle a rating of ten out of ten.
(1) Total configuration over the project's framework/schema to meet my program requirements or business culture.
(2) Bi-directional traceability, with linked cross referenced parameter rules, tailored to my specific views.
(3) Complete systems engineering tool suite (requirements management, modeling, document publishing, configuration management, etc.) in one affordable product.
3SL Cradle enabled my current and former organizations to be champions of requiring and providing bi-directional traceability to all relevant data, from cradle to grave -- the entire project lifecycle -- due to the tool’s ability to be customized with ease and ability to produce products that builds confidence in project stakeholders.
Cradle provides modelling diagrams that can be created and referenced to relevant data in my project databases. In other words, I can create a use case diagram and reference relevant parts of that diagram to relevant data in my project (e.g. system requirements). Cradle provides around 15 mode ling notations (e.g. Data Flow Diagrams, State Transition Diagrams, Use Case Diagram, etc.); however, SysML and DoDAF are not included. In my line of work, I'm requested to use SysML and DoDAF to communicate requirements to my stakeholders. An improvement to Cradle would be to include the SysML and DoDAF modelling notations. I hope I've clarified my feedback review, area of improvements, for Cradle.
No issues with deployment.
No issues with stability.
No issues with scalability.

3SL is very user-friendly for a small project.
The support is consistent globally. However, heavier support is provided in certain locations. Improvement in support is necessary. Assistance is available to acquire information and utilize usernames. Enhancements are required for user information support.
The solution is reliable.
The solution is highly scalable.
The initial setup is complex. If you are not familiar with 3SL Cradle, you need to read the documents. It's important to start with the requirements and proceed to the Cradle tutorial. Pay close attention to details to better understand how to use the tool.
The solution increases our efficiency by 25%.
The price is similar to IBM RATIONAL DOORS.
We evaluated Jira.
If you have time to take some courses about 3SL Cradle, it will give you more time in the project to familiarize yourself with Cradle. I recommend it, but you need to do it within a very short time.
Overall, I rate the solution a seven out of ten.
