Let’s talk about how value conflicts in requirements get resolved

Here’s the thing about software projects: people bring not only needs, but deeply held values. A client might prioritize speed to market, while a developer might prize maintainability or user privacy. When those priorities clash, the way we resolve the tension matters as much as the decision itself. This isn’t just a test question. It’s a real-world dance between objectives, beliefs, and trade-offs. And yes, you’ll hear several approaches tossed around in the field. Four of them are particularly common: overruling, plus-minus-interesting (PMI), compromise, and the decision matrix. Let me explain how each one works, and why the last one—though valuable in many contexts—often falls short when values are on the line.

A quick tour of the four techniques (in plain language)

• Overruling: This is when someone with formal authority makes the call, effectively saying, “We’re doing it this way.” It can move things forward fast, which is appealing in a tight schedule. But it can leave the other side feeling cut off, ignored, or unheard. When values are in play, the risk is not just a bad decision; it’s damaged trust.

• Plus-minus-interesting (PMI): A lightweight, human-centered approach. People lay out what’s good (plus), what’s bad (minus), and what’s interesting (ideas worth exploring). It invites dialogue, helps surface different perspectives, and keeps the conversation human rather than purely numeric. It’s particularly handy when values are at stake because it creates space to discuss why something matters beyond dollars and hours.

• Compromise: Here, each side concedes a bit to reach a middle ground. It recognizes the emotional layer behind the disagreement and can preserve relationships. The downside is that both sides may walk away with something that doesn’t fully satisfy their core values. Still, it often yields a practical path forward without sinking into stalemate.

• Decision matrix: This tool tries to add objective weight to options by scoring them against criteria. It sounds fair and rigorous, which is why it’s so appealing in many scenarios. But there’s a catch: value conflicts aren’t just about numbers. They’re about ethics, priorities, and what people hold most dear. A matrix tends to quantify what people feel, which can flatten the deeper aspects of the disagreement.

Why the decision matrix tends to be least suitable for value clashes

• Values aren’t easily measurable: A matrix shines when you can pin down concrete, checkable criteria. But when the core issue is a matter of trust, privacy, user dignity, or long-term impact on a community, those aren’t always reducible to numeric scores. The emotional weight behind a choice rarely shows up on a grid.

• Subtlety gets lost: Even if you assign weights and scores, you may miss the nuances that make a value conflict what it is. People don’t just want the best feature; they want alignment with principles. A matrix can look neat on paper while leaving the heart of the matter untouched.

• It can seem cold or impersonal: When you try to “quantify” values, you risk signaling that feelings and beliefs are less important. That can shut down honest dialogue right when it’s most needed.

• It might stall conversation: If every option looks acceptable on paper, teams can end up stuck in analysis rather than moving toward understanding. In value conflicts, the path forward often starts with listening, not scoring.

A little story to ground the point

Imagine a client who prioritizes rapid delivery for a new customer-facing feature. A developer, meanwhile, worries about security and data privacy. If the team tries to settle this with a decision matrix, they might score speed, cost, security, and privacy, assign weights, and end up with a “best” choice that technically satisfies more criteria. But if the client’s core value is market advantage and the developer’s core value is responsible handling of user data, the chosen option may still feel wrong to one side. The matrix gives a clean answer, but it doesn’t necessarily bridge the gap in who those values belong to, or how the decision will be perceived in the future. That gap is where trust either grows or frays.

When to use each approach (a practical lens)

• Overruling can be appropriate in governance contexts or when a decision must be made quickly to protect safety, regulatory compliance, or large-scale risk. It’s not inherently sinister; it’s about making the call when there’s a higher authority or a higher stake. But use it sparingly, and with a transparent rationale, so others understand the why behind the order.

• PMI shines in early-stage conversations where there’s value tension but a willingness to listen. It invites stakeholders to articulate what matters and why. It keeps the discussion human, and it’s a gentle way to surface hidden concerns before a path is chosen.

• Compromise is the bread-and-butter of ongoing collaboration. It recognizes that no one gets everything they want, but everyone gets something workable. It’s especially useful when relationships matter, and when you want to preserve momentum while keeping lines of communication open.

• The decision matrix is best kept for cases where criteria are well-defined, objective, and largely technical. If you’re comparing architecture options, performance benchmarks, or cost implications with clear data, a matrix can be a very helpful compass. Just don’t pretend it captures the entirety of a value debate.

A practical approach you can apply

• Start with listening: In value clashes, the starting move should be to understand. Let the other party explain why a choice matters. Ask clarifying questions and reflect back what you heard. This shows respect and helps surface the real levers behind the positions.

• Bring PMI to the table: After listening, run a quick PMI session. List the pluses, minuses, and interesting ideas. The structure helps people articulate values without turning the discussion into a tug-of-war.

• If a stalemate remains, explore a targeted compromise: Look for a middle ground that preserves core values on both sides. This might mean adjusting scope, timing, or safeguards to honor the most important concerns.

• Keep governance in view: If a decision carries significant risk or policy implications, document the decision, the reasoning, and the values involved. When people feel heard and the rationale is transparent, even difficult outcomes land more smoothly.

A note on the broader picture in IREB knowledge

Foundation-level concepts in conflict resolution are not just about ticking boxes. They’re about understanding how requirements intersect with human factors. The best outcomes come from a blend of empathy, structure, and timing. A disciplined approach to disagreements isn’t about choosing the perfect method every time; it’s about choosing the right mix for the moment, then adjusting as reality evolves.

A few tips to keep the momentum going

• Avoid rushing to a numeric verdict when a value conflict is on the table. Slow down enough to hear what’s at stake.

• Use real-world examples to illuminate values. Concrete stories help people connect with ideas more deeply than abstract criteria.

• Remember that language matters: Frame issues in neutral terms, acknowledge emotions, and avoid blame. The goal is shared understanding, not winning a verbal duel.

• Foster a culture of ongoing dialogue: Value conflicts aren’t one-and-done events. They recur as projects unfold or as requirements evolve. Build processes that invite continual conversation rather than one-time decisions.

Bringing it back to everyday practice

If you’re navigating requirements in a team, you’ll likely encounter moments when numbers aren’t enough. You’ll need the human side—the patience to listen, the courage to talk through values, and the flexibility to find a workable path. In those moments, the decision matrix often takes a back seat to more relational methods like overruling (when necessary), PMI, and true compromise. It’s not about choosing the approach with the flashiest name; it’s about choosing the approach that respects people as much as the project.

Final thoughts

Conflict resolution in requirements is less about picking a single tool and more about choosing the right rhythm for the moment. When clients and developers face a value clash, the decision matrix is the least suitable of the four options because it leans on objective scoring rather than subjective understanding. The other methods—overruling, PMI, and compromise—offer pathways that honor beliefs, priorities, and ethics while keeping the project moving.

If you’re curious to dig deeper into this topic, pay attention to how stakeholders articulate what matters to them, how facilitators guide conversations, and how teams document the outcomes in a way that future decisions can build on. After all, the heart of value-focused requirements work isn’t just about delivering features; it’s about delivering outcomes that everyone can stand behind.

Want to explore more about conflict resolution in a practical way? Look for real-world case studies that show how teams navigated value tensions, the choices they made, and the lessons learned. The more you see these dynamics in action, the sharper your instincts will become for guiding conversations toward thoughtful, humane, and effective results.
