This webinar provides insights into the use of modules of metrics (MoM) in the California High-Speed Rail System (CHSRS), a multi-billion-dollar program procured in several individual procurement contracts including civil works, track and systems, trainsets, and the train operator. There are currently three active civil works contracts, spanning 119 miles including the Design and construction of over 225 different guide way sections, aerial structures, trenches, roadway overheads, and other structures.
requirements are managed in DOORS, with hundreds of modules and thousands of requirements in each contract. With the progression of design and construction metrics were developed, measuring how the requirements were addressed in several thousand contractor design and construction submittals, eventually evolving into the MoM approach. As the first structures are being readied for acceptance, certification and hand-over to the next track and systems contractor, it is of even more importance to demonstrate that all applicable requirements have been satisfied by each contract.
The CHSRS MoM approach has been successfully implemented as a pilot for one the three civil works contracts and is planned to be rolled out to the remaining civil works and any or the future contracts. This webinar will discuss the MoM objectives, challenges, implementation, and the use of the MoM for both technical and managerial use.

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.
Useprototypingto 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.
Alwaysrespondto 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.
Createa 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.
IBMrequirements 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.
