SHRINIVAS ALAGERI - PeerSpot reviewer
Offers a well-refined ASPICE template and satisfying requirement management features
IBM DOORS effectively synchronizes with Polarion. But suppose when Polarion is running on Linux and you want to integrate with IBM DOORS on Windows, that is when compatibility issues arise. For the aforementioned issue we often receive advise in our company to migrate Polarion to Windows before integration. IBM DOORS is a heavy-duty application compared to competitors such as PTC Integrity. Exporting an IBM DOORS module is highly time-consuming for its bulkiness. PTC Integrity is a lighter solution that allows the development of a gateway template. It's crucial to consider the use cases and the other vendors that need to be integrated before using IBM DOORS. Our company is a PTC competence center, so most of our customers are from PTC. The customer integrations our company deals with include modeling tools such as Simulink, MATLAB, and Integrity Modeler to synchronize documents. The digital threat maintenance between IOD and Windchill is also a crucial part of our organization's operations. The solution should be more compatible with thin clients, there should be focus on web-based clients who can be more effective in IBM DOORS. At our company, we don't want every customer to use the thick client format with the solution. I would like to witness the seamless integration of IBM DOORS with Windchill in the future version. The integrations in IBM DOORS should be web-based, I don't prefer to use multiple plug-ins. For example, I want to integrate IBM DOORS with MATLAB, Simulink and Jenkins effortlessly which is possible in Codebeamer. I want every feature of Codebeamer to be present in IBM DOORS in the future releases.

Jason Lopez - PeerSpot reviewer
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.

Quotes from Members

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

Pros

"I really enjoyed the API."
"The most valuable feature for me is the ability to enter data into one table, or context, and link it across modules."
"It helps to manage requirements efficiently, which significantly improves the way requirements are managed."
"It is a mature product that is stable."
"I would say that the best feature of the solution is that since everything is in one place, and if you make any changes, then they are recorded or tracked."
"The next-generation features are good."
"It is a stable solution."
"The traceability matrix in DOORS improved our project outcomes. It helps ensure coverage of requirements at different levels, from user requirements to software requirements to test requirements."
More IBM DOORS pros
"Inflectra SpiraTest has a lot of functionality, which is good."
"The features of this product most valuable to me were the test case management and the visual status, by which it was displayed."
"We were able to add a step-by-step procedure for someone to follow to assist in testing."
"The reporting functionality helps vendors and technical resources identify bugs and issues that need to be addressed. The simple dashboard-style home page makes training end-user testers simple and straightforward. The actual testing UI is VERY straightforward and very intuitive for the end-users that test the system since very often we pull from business and operational users to help test new systems."
"The user-friendly features are the most valuable. For example, migration of requirements and migration of test cases and the creation of traceability. You have various reports that you need. The plug-ins that are available to connect with the other tools."
"The ability to reuse test cases already used across projects is the most valuable feature of this solution. We don't need to create new ones."
"I found Inflectra SpiraTest intuitive enough. It's also easy to learn, so this is what I like about it."
 

Cons

"It could be more user-friendly. It's not a beautiful tool. The user interface is gray. It has only lists inside, and it's horrible when you want to add tables. It's tough to add tables and manage them. It also becomes difficult when you want to add images."
"It would be nice if it could be scaled-down so that it could be installed and implemented without much learning or training."
"They need to provide users with information on what options would be best for their setup."
"There are problems with communicating between DOORS and Microsoft Office."
"The web application DOORS Web Access doesn't have the same functionality as the standard client, so it's not a real substitute. For example, web Access only provides writing requirements, but you can't do much more with it."
"The interface is not very user-friendly and has not evolved in a long time."
"It would be helpful if Microsoft provided a more user-friendly interface for updating and querying updates. Additionally, if there was a way for users to notify developers of any changes in requirements, it would allow for faster and more efficient updates to the solution's architecture. This could be in the form of a notification system that alerts developers of any changes that need to be made. Additionally, the solution is document-driven and it should be more digital."
"The performance could be improved. It doesn't run as smoothly as it could."
More IBM DOORS cons
"The UI for managing test cases, test sets, test runs could be a little more integrated, currently, these feel disjointed at times and confusing. Also, the test steps page needs to display the test steps closer to the top of the UI so as to not have to scroll down to find."
"Migrating is not very easy. It depends on the organization, how efficient and effective the decision-making process is. The plug-ins should be easier and more integrated rather than the user trying to integrate the tools which are more popular, like Jira et al."
"The folder organization in Inflectra SpiraTest could be better, though I cannot comment whether that is structure-related. Most of what I need would probably be in the tool, but as a test manager, I need to be able to create dashboards and reports easily."
"The user interface is slightly complicated and not very consistent. It could be more user friendly."
"Being able to add scripting for testing can and does save a lot of time. When you are able to just ‘run’ a test case rather than manually add it and run it."
"It should develop integration with JIRA. We have some complexities which caused us not to decide to integrate it with our JIRA, like synchronous data."
"Two areas that can stand improvement: integration with third party products and making it more intuitive."
 

Pricing and Cost Advice

"Pricing can vary depending on the size of the organization and how contracts are negotiated."
"IBM DOORS is available at a reasonable price"
"The licensing cost is too high."
"I don't personally know what the numbers are. I just know that one of the reasons we've limited it to three seats is a function of cost."
"I am not sure why it is so expensive, but one license will cost approximately $15,000 in US dollars."
"IBM Rational DOORS is highly expensive."
"We have to pay for a license. I think it's a one-time payment as my company hasn't notified me about more charges. I don't think it's expensive for large corporations, but it will be costly for an average person."
"It's expensive."
More IBM DOORS pricing and cost advice
"I Googled the pricing for Inflectra SpiraTest, and it's about $4,000 annually."
"The pricing was excellent. I would recommend the enterprise solution."

Overview

IBM Engineering Requirements Management DOORS (DOORS) is a Requirements Management (RM) software designed to help organizations manage engineering project requirements throughout the development lifecycle. It provides a central location for capturing, defining, and organizing project requirements, facilitating communication and collaboration among stakeholders like engineers, system designers, and customers. Key features include requirements traceability, version control, and impact analysis, ensuring effective implementation and testing. DOORS improves efficiency, enhances communication, reduces risks, and supports better decision-making through clear visibility into requirements. Compared to its newer, web-based counterpart DOORS Next, the mature DOORS 9 offers a wider range of features with a traditional user interface but lacks web-based functionality and modern integration with IBM Engineering Lifecycle Management (ELM) tools.
