Building on the themes of ELM 7.0, our next release is just around the corner. Since 7.0.1 has come so soon after 7.0, we recommend that anyone planning to upgrade should go straight to 7.0.1. This blog covers releases of all Requirements Management tools including:
- IBM Engineering Requirements Management DOORS Next 7.0.1
- IBM Engineering Requirements Management DOORS 9.7.2
- IBM Engineering Requirements Management Requirements Quality Assistant
DOORS Next 7.0.1
One of the themes of DOORS Next V is to extend the overall scale of data that can be managed using a DOORS Next RM server. Testing has continued in V7.0.1 and we can now support up to 1,000 concurrent users working on a single RM server using an Oracle database.
It is often the case that when using changesets to modify requirements, dependencies between changesets are created when multiple people change the same requirements or are making changes in the same module when there are changes to the structure of the module. DOORS Next V7.0.1 allows for dependencies to be overruled when selecting changesets for delivery.
Trace column information can be tailored to be more succinct in the information that is displayed, including the use of traversable Link Indicators rather than displaying more verbose URLs.
ReqIF has been improved in the way attachments and graphical elements are used as part of Requirements information. Where possible, DOORS Next will now import OLE elements from applications like DOORS directly into attachments in DOORS Next. DOORS Next will export graphical elements such as Diagrams in a format that can be seen, but not edited in other requirement tools, including DOORS.
DOORS V9.7 was introduced to enhance usability while focusing on integrating DOORS more closely with the IBM Engineering (ELM) portfolio as a whole.
- Extending support for collaboration with ELM and Global Configurations, enabling the DOORS user to see and create trace links to ELM (OSLC) data placed under configuration management
- We have made a number of improvements for reporting; most significantly is the ability to report on requirements volatility using the Jazz Reporting System Report Builder.
- ReqIF interaction with IBM Engineering DOORS Next has been improved to allow OLE data from DOORS to be directly sent to DOORS Next as attachments without the need for wrapping elements. It is also possible to see DOORS Next diagrams for review in DOORS.
- The DOORS database explorer shows modules and their baselines to make it easier to open the correct version. Optionally, the module explorer can limit the display to active objects covered by an active filter.
Requirements Quality Assistant
Requirements Quality Assistant is a hosted solution with updates typically released monthly.
- RQA can be added to existing deployments or can now be purchased as part of a dedicated DOORS Next SaaS environment, with the power of AI
- through Requirements Quality Assistant
- Requirement Managers get the full capability of DOORS Next Analyst. to optimize communication & collaboration across teams
- Requirement Authors receive coaching from RQA to improve the quality of a requirement as it is being written
RQA scores requirements against criteria consistent with the INCOSE Guidelines for Writing Good Requirements. The tool is pre-trained to detect 11 quality issues and can be extended with more through the support of IBM services.
After analyzing requirements, see the issues found by RQA in the list of attributes in DOORS Next & DOORS. Use the issue guidance to modify requirements and reduce ambiguity. For more information, see Checking DOORS Next requirements with RQA
In recent releases, we have refined the accuracy and scoring and you can now measure the quality of your project or module and use Dashboard views to provide insights on problem projects.
Thank you for your continued support and stay safe.

Don’t get caught
A trap is a position or situation from which it is difficult or impossible to escape. Getting caught in product or software development requirement traps can be problematic. The traps of bad requirements definition and management result in cost overruns, missed deadlines, poorly designed products, and a failure to deliver what the customer needs.
Unfortunately, requirement traps are common. The State of the IT Union Survey explored the development management practices that teams applied to either stay out of trouble or address problems after they are discovered. The online survey of respondents reveals how often product development teams anticipate that they’ll fall into traps. They pad budgets and schedules. They change initial estimates to match actual results. And they request additional resources. Figure 1 reveals the lengths teams and team leaders will go to deal with these traps.
Poor requirements management results in inconsistent project outcomes.
Products today depend on software to deliver their value. A brake sensor on a car, a home appliance, a medical device—all contain software that plays an increasingly important role. The products are becoming smarter, and they involve more people and teams outside the typical value chain. Smarter management of the requirements process— the foundation of effective product and software delivery— is increasingly important for delivering these products.
This article presents 10 common mistakes that project teams make in defining and managing requirements. More importantly, it discusses how to avoid these traps so you can get your requirements right and develop the right product on time and within budget.
Trap 1: scope creep
Scope creep usually involves features being added to previously approved product designs without corresponding increases in resources, schedule, or budget. The potential causes vary, but creep tends to occur when project requirements are not defined and managed properly.
Creep can also occur when development teams create solutions before determining what the business needs. The business requirements of a project are typically seen by development teams as being too high level and vague and not applicable to them. They want to focus on detailed product requirements. However, business requirements are real requirements and they need to be sufficiently detailed to avoid scope creep. By meeting the product requirements and not the business ones, teams fail to develop solutions that provide value and may overcompensate by adding features.
Avoid the trap
- Map detailed, real business requirements to product features that satisfy those requirements and provide value.
- Manage change, be vigilant about focusing on business requirements prioritization.
- Identify and work with stakeholders early and often to understand the business requirements, stakeholder priorities, and the effect on stakeholders when changes occur.
The payoff: Avoiding scope creep makes planning easier, helps keep budgets intact, and helps keep projects on schedule. Most important of all, it helps generate the desired return on investment.
Trap 2: asking customers what they want
This seems counter-intuitive. Teams are supposed to talk to customers and give them what they want in a product. But customers tend to talk about features, not what they truly need. The truth is that people often don’t know what they want. And when customers don’t know what they want and developers don’t understand the problem, poorly conceived solutions— and products— can result.
Avoid the trap
- Ask customers why they need a particular capability. It may lead to a better understanding of their expectations and better discussions about specific requirements.
- Guide the discussion away from focusing on features— ask customers what they want the product/software to do. Create a separate discussion for how the resulting products will be used.
- Identify the right stakeholders. The target audience or end-user may not be the person who is responsible for the project or invested in its success. Find— and listen to— the right mix of users, customers, executives who fund the project, government representatives who impose regulations, project teams, support teams, and others.
The payoff: Asking customers what outcome they are seeking helps you determine the true and realistic product requirements that will deliver value to them.
Trap 3: inability to adapt to change
Setting requirements in stone early in development can be a recipe for disaster that results in an enormous waste in resources and an inability to stay on schedule. As recent changes in the global economy illustrate, outside influences can quickly change project requirements. Organizations have quickly changed their focus to doing more with less. Speculative or experimental pet projects are off the table, replaced by those with strong potential ROI. Yet in any economy, there are always new requirements to contend with as business priorities change, new government regulations are enacted, and new stakeholders are identified. Project teams need to accommodate those changes.
Avoid the trap
- Expect and plan for requirements that change throughout your development process.
- Re-prioritize requirements based on shifting circumstances such as business needs, customer importance, estimated effort, and cost.
- Have a fine-grain plan that you adjust at regular intervals.
- Keep your stakeholders informed as changes occur— get their input for prioritization and the rationale behind it.
The payoff: Accommodating and planning for change in project requirements helps mitigate risk and decreases costly rework.
Trap 4: failure to communicate effectively
Ineffective communication is often a root cause of project failure. The perspective of development teams, customers, end-users, and executives are different for each group, as are their needs for communication. If you don’t express requirements using methods your stakeholders can easily understand, you can’t possibly gain consensus on requirements.
Avoid the trap
- Know your audience and communicate in ways that help them understand the information. Make use of diagrams, user stories, sketching, and storyboards.
- Create glossaries, document templates, and feedback forms that are clear, concise, and easy to use.
- Use prototyping to help stakeholders visualize the solution. This can either augment text or completely replace it depending on the level of detail required.
- Elicit feedback from all of your stakeholder representatives. Remember that one or two people tend to be the most vocal. Don’t make the mistake of overlooking others’ feedback.
- Always respond to feedback, preferably with some clear statement of status such as, “will incorporate,” “placed on a wish list” or “unable to accommodate” If you ask for input, acknowledge it.
The payoff: Effective communication makes the most efficient use of everyone’s valuable time and helps avoid misunderstandings that derail projects.
Trap 5: failure to communicate frequently
Failure to communicate with stakeholders early and often leads to one primary problem: rework. Developing a product for customers without consulting them while that product is being developed is just asking for trouble. The biggest reason it happens is that we often think we know what our customers want well enough that we don’t need to consult them. And stakeholders usually have different priorities.
Sometimes teams don’t communicate with stakeholders because they prefer to avoid confrontations. But if you want a positive result and minimum risk and rework, it is important to collaborate with stakeholders not just at the beginning of a project but throughout the entire process, from start to finish.
Avoid the trap
- Identify key stakeholders, including customers. Choose a representative from each group to communicate with regularly.
- For large, in-person stakeholder workshops, consider using skilled facilitators. Good facilitators are worth their weight in gold in keeping everyone on track for attaining the meeting objectives.
- Establish regular checkpoints with your stakeholders. Determine at the beginning of the project how often you need to check-in. Schedule time for keeping stakeholders up to date as unexpected changes occur.
- Make it easy for your stakeholders to provide feedback. When they do, let others see their feedback to generate better discussions.
The payoff: Regular communication reduces risks, increases team productivity, and avoids rework. Ultimately it helps deliver the product the customer wants.
Trap 6: unwieldy documents and too much information
Do you have time to review and give feedback on a 200-page document? Probably not— and most likely, neither do your stakeholders. Doing more work than necessary and adding unnecessary detail to documentation costs both time and money. It is unproductive for the person creating it and a hindrance to the people looking for information they need to get their work done. Two common missteps include adding too much detail to requirements too early in the process and requiring more traceability than is necessary to facilitate effective lifecycle management.
Think quality, not quantity. Better to add just enough detail to your requirements and identify just enough traceability to get the job done— not the entire job, but the next piece or iteration that needs to be completed.
Avoid the trap
- Large, dense documents are not very consumable by stakeholders. Invest in communication tools that efficiently gather and disseminate requirements information.
- Use visual techniques to model business and product requirements. Business process diagrams and use case diagrams, storyboards, and sketches can help cut through text-heavy clutter.
- Provide a glossary of industry terms, acronyms, and domain-specific terms to facilitate communication.
- Create transparency of feedback. When your stakeholders can review each other’s feedback, the discussion is richer, problems come to light, missing requirements are identified and necessary details get filled in.
- Add just enough information to your documents so the rest of your team members can complete their work.
- Remember that requirements management is an ongoing process. There will be other opportunities to add more detail to requirements and to capture more traceability later when it may be more appropriate.
The payoff: Focused documentation and feedback loops increase the efficiency of all stakeholders. Reduction of extraneous details in both requirements and traceability increases quality by focusing on the most important information— while postponing further detail until it’s needed.
Trap 7: hidden project artifacts
Engineers, developers, and testers often aren’t aware of the project vision or can’t locate the documentation for the architecture or the business requirements— that is, if they’re created at all. Without easy access to these foundational documents, how can we possibly expect them to deliver models, code, and tests that solve the right customer problems? We can’t. Transparency to all project artifacts is critical to the success of any software project.
Avoid the trap
- Keep all project artifacts in a central repository that is accessible by project team members. Having to search multiple sources for relevant documents is frustrating and time-consuming.
- Make sure documents are categorized and managed in such a way that they are easy to find.
- Ensure that when changes occur, the team is informed. Automatic notifications can help deliver this information.
The payoff: Accessibility and management of information and transparency of project artifacts reduces rework, diminishes waste, and promote reuse because it makes collaboration and communication easier.
Trap 8: Ambiguous requirements
Ambiguous requirements are the result of unclear or missing information. This leads to confusion and rework. Project teams spend too much time trying to get clarification so they can design, code, and test. It’s very difficult for engineers or architects to develop relevant models, developers to write defect-free code and testers to develop the right test cases without clear requirements. Unfortunately, reworking requirements are so common that it can become an accepted practice— rework is just built into the schedule and budget.
Ambiguity also tends to push risks into the next phase of the project. Requirements then have to be reworked, and that poses problems to project schedule and cost. This trap is especially damaging to fixed-cost projects.
What causes ambiguity? Poor writing, inaccurate information, and the assumption that the audience understands just as much as you do.
Avoid the trap
- Use a writing reference, such as Elements of Style by William Strunk and E.B. White— which has long been considered the authoritative reference on writing crisp, clear text— before and during requirements creation.
- Create a glossary, and make sure every acronym and technical term is included.
- Pretend you are writing for a student just out of college or someone who recently joined the organization. Don’t assume the audience will know every term and understand every concept.
- Augment text with visuals. It’s a great way to express both simple and complex concepts.
- Step back. After writing any draft document, put it down for a while and read it later. A fresh perspective can reveal ambiguities.
The payoff: Clear, understandable requirements are the foundation of your software project.
Trap 9: failure to measure and assess requirements processes
Defining and managing requirements can be a complex task. Missing and ambiguous requirements can easily result in missed schedules, cost overruns, and decreased productivity and quality as downstream project deliverables fail to provide value to stakeholders. Don’t wait for disaster to strike— assess your project status regularly.
Organizations must have the ability to review, assess, and improve their requirements process. Having accurate insight into data, processes, and practices is a key component of success. Measuring project and process outcomes allow for continual process improvements across the software delivery lifecycle, which reduces project failures and lowers business costs.
Avoid the trap
- As part of your process, conduct a “lessons learned” feedback session at the end of each development iteration or release.
- Also, do a “lessons remembered” session before starting a new project. To encourage continual improvement, you need to not only capture lessons learned at the end of an iteration or release but also reinforce those lessons as you move forward.
- Define and collect metrics that ensure your success. For example, measure the impact of changes to your requirements, test case coverage, priority, cost and effort of business, and product requirements. As you become more experienced with measurement, you’ll find just the right combination of metrics that allows you to continually improve your requirements process.
The payoff: Ongoing measurement of project performance reveals small problems before they become big issues.
Trap 10: Isolating your requirements
Viewing requirements as isolated entities, failing to capture relationships between requirements and other artifacts, and failing to recognize dependencies between requirements leads to increased project risk and rework. Re-prioritizing one requirement without considering its effect on other requirements results in increased project risk and costs.
For example, a risky trap that organizations often succumb to is not capturing the relationship between project requirements, business requirements, and other downstream deliverables such as models, test cases, and defects. When you fall into this trap, you deliver a product that doesn’t satisfy stakeholder needs.
Avoid the trap
- Identify relationships between requirements and then manage them together.
- Create the right level of traceability between requirements and downstream deliverables that balances the traceability needed for effective lifecycle management with support for productivity.
- As you make changes to requirements and re-prioritize them, consider the effect of these changes to related requirements and your downstream deliverables.
- Use tools that allow you to easily visualize the relationships you’ve identified.
The payoff: Identifying and managing relationships between requirements and other artifacts mitigates project risk; helps ensure alignment between your business requirements, product requirements, and downstream deliverables; and results in lower development costs.
IBM requirements solutions can help you avoid common software development traps.
There are many traps in software. Some of the most expensive ones occur in the requirements space because that is where the foundation for your project is laid. Lack of planning, lack of communication, and collaboration with stakeholders, ineffective requirements elicitation, and requirement management techniques all lead to problems. When we don’t measure how we’re doing and continually make improvements, the risk escalates quickly and the project gets out of control— something you may never recover from.
IBM software requirements solutions incorporate many best practices that help you avoid these common traps and enjoy the payoffs.
IBM’s requirements management solution enables you to capture, trace, analyze, and manage changes to requirements in a secure, central, and accessible location. These capabilities strengthen collaboration, increases transparency and traceability, minimizes rework, and expands usability.
