Accountability Diffusion Trap

Most mistakes in Scrum aren’t because people don’t understand the framework—they come from applying reasonable thinking in the wrong context. Cognitive traps happen when decisions favor efficiency, control, or comfort over transparency, inspection, and adaptation. Here is one of ten cognitive traps, Accountability Diffusion. Sharing accountability across multiple people slows decisions and removes the clarity needed for Scrum accountabilities.

Simulated Assessment Question

A product is very complex with multiple technical layers, political ramifications, and demanding customers.  Multiple people share Product Owner responsibilities since it seems no one person can manage the whole responsibility. What is the best assessment?

A.   This encourages corporate collaboration

B.    Acceptable since the product is layered

C.    Reduces accountability for Product Owner role

D.   Improves decisions because one Product Owner isn’t enough

Answer: C

Why this is correct

At first glance, sharing Product Owner responsibilities sounds like a good idea. More people involved should mean better decisions, broader perspective, and stronger alignment across stakeholders. That’s usually the intent. But in practice, it doesn’t work that way.

Scrum is very deliberate about having a single Product Owner, and it’s not because one person is expected to have all the answers. It’s because someone needs to make decisions clearly and without hesitation. Product ownership is not about collecting input—it’s about deciding what gets built and in what order, and doing so in a way that keeps the team moving.

Once that accountability is shared, decision-making changes. What used to be a decision becomes a discussion. What used to be clear direction becomes something that needs alignment. Even when everyone involved is capable and well-intentioned, there’s a natural tendency to defer, to check, to make sure others agree before committing.

That slows things down. More importantly, it creates ambiguity. The team no longer has a clear sense of who owns the Product Backlog. If priorities shift or something doesn’t land well, it’s not obvious who is accountable. Responsibility spreads out, and when that happens, it effectively disappears.

Collaboration is still essential. Stakeholders, customers, and team members should absolutely contribute ideas and input. But input and accountability are not the same thing. Scrum separates those on purpose. Many people can contribute to the decision, but one person needs to make it.

The trap

This is diffusion of responsibility, and it often emerges in larger organizations. In practice, it looks like:

·       committees making product decisions

·       multiple stakeholders acting as Product Owner

·       shared ownership of prioritization

It usually starts with a reasonable concern. The product is complex, there are multiple stakeholders, and no single person feels comfortable owning all of it. So responsibility gets shared in an attempt to reflect that complexity. On paper, this looks like maturity—more voices, more alignment, more shared ownership.

But what actually happens is that decision-making becomes slower and less clear. Instead of one person making a call, decisions move through conversations, side discussions, and informal approvals. Priorities get negotiated instead of set. Work gets added because someone important asked for it, not because it fits a clear product direction. Over time, the Product Backlog stops representing a strategy and starts reflecting a collection of competing interests.

You also start to see hesitation. People hold back from making decisions because they don’t want to override someone else. Or they make decisions tentatively, expecting them to be revisited. That leads to churn—priorities shift, direction changes, and the team ends up reworking things that were already “decided.”

From the team’s perspective, this creates constant friction. They’re no longer working from a clear, stable set of priorities. They’re interpreting signals, trying to reconcile different inputs, and second-guessing what really matters. That slows execution and erodes confidence.

And when something goes wrong, accountability is unclear. Because multiple people were involved, no one person is fully responsible. Issues get explained instead of owned. Decisions get justified instead of improved.

That’s the deeper problem. Scrum isn’t trying to reduce collaboration—it’s trying to make it effective. The Product Owner doesn’t have to know it all but should absolutely engage others, gather input, and consider multiple perspectives. But at the end of that process, someone has to decide and stand behind that decision.

That clarity is what allows the team to move quickly and stay aligned. Without it, you don’t get better decisions—you just get slower ones with less accountability.

If this required thought—or felt even slightly uncertain—that’s the point. Cognitive traps don’t get resolved through reading; they are discovered and avoided through deliberate practice. The most effective way to discover cognitive traps is through classes. If you want to identify and eliminate these patterns, take one of my classes or run through a simulation assessment.
