Featured Reviews

Amol Dumbre - PeerSpot reviewer
Software Manager at Forvia
Integrated lifecycle management has supported global A‑SPICE projects and custom reporting
I believe the toolchain currently covers all of our requirements. Even for A-SPICE and related requirements, I can add attributes and manage things effectively because the tool is highly customizable. I can continue updating things and managing different processes. The only gap I have identified is in code-level coverage reporting. I have coverage traceability from IBM DOORS through the architecture and design, but I am unable to demonstrate code-level coverage reporting. That reporting capability would be helpful. Testing is covered very well through IBM Test Manager. The traceability to code is something I feel there may be certain gaps in, though I may not be fully aware of all capabilities since my role is different and I primarily receive reports rather than being an end user. Regarding the traceability feature, I am not an end user but rather receive reports from my team, so my perspective is limited.

Intuitive enough and easy to learn, but in terms of folder organization, it could be better
Inflectra SpiraTest is the new kid on the block compared to Jira and Azure. Still, when I started exploring the tool, I realized that it was no different from other tools I've used in the past, but it all boils down to adaptability because the features would always be more or less the same. I found Inflectra SpiraTest intuitive enough. It's also easy to learn, so this is what I like about it.
