Making cross functional working work and why it matters

Poor communication and collaboration have measurable operational costs. PMI reported that ineffective communications contribute to project failure, and that clear, audience-appropriate communication is strongly associated with more projects meeting their goals, finishing on time and staying within budget. In organisations where work and projects increasingly cut across teams and specialisms, getting communication and collaboration right first time matters.

What do we mean by cross functional working?

Cross functional working is about people from different teams, professions or parts of the organisation working together to achieve shared outcomes.

It is not just about:

• attending more meetings
• copying more people into emails
• or being ‘nicer’ to other teams.

At its best, cross functional working is intentional. It involves shared understanding, clear ownership and the ability to work productively with difference – whether that difference is in priorities, pressures or ways of thinking.

The benefits of working well across teams

When organisations invest in effective cross functional working, the benefits are tangible.

Teams make better decisions because problems are viewed from multiple perspectives, rather than through a single functional lens. Work moves faster because dependencies are understood earlier and issues are resolved before they escalate. Relationships improve, making it easier to collaborate when things are under pressure.

When teams understand each other’s roles, pressures and priorities, they are also more likely to make changes in ways that add value for others, not just their own team. This reduces the risk of solving one problem while unintentionally creating another further up or down the line and helps improvements stick across the whole system.

There is also a clear performance case. Research consistently shows that teams that communicate well can increase productivity by up to 25%, driven by better alignment and fewer misunderstandings. In practice, this means less duplication, less rework and more time spent on work that genuinely adds value.

Cross functional working helps organisations move away from fragmented effort towards coordinated action; something that is essential in today’s operating environments.

What happens when collaboration breaks down?

When cross functional working doesn’t function well, the impact is often immediate.

Common symptoms include:

• siloed decision making
• duplicated or conflicting work
• delays caused by unclear ownership
• frustration between teams who feel they are working at cross purposes.

Over time, these issues erode trust and accountability. People become more cautious about raising issues, less willing to challenge assumptions and more focused on protecting their own area of work. The organisation slows down – often without fully understanding why.

The hidden cost of poor communication

One of the biggest barriers to effective cross functional working is not a lack of effort, but a lack of clarity.

When teams build shared understanding of one another’s priorities, pressures and expertise, collaboration becomes faster and more effective. CIPD research on cross-functional collaboration highlights shared purpose, openness and expertise-sharing as key enablers of effective work across boundaries.

Poor communication increases stress, fuels misunderstanding and contributes to disengagement. People may be working hard, but without shared understanding, progress stalls.

UK engagement data reinforces this. Only a small proportion of UK employees report being truly engaged at work, and communication quality is consistently identified as a key driver of engagement and trust. Where people feel informed and listened to, motivation and performance improve; where they do not, they decline.

Why cross functional working is harder than it looks

Most people want to work collaboratively, so why does it so often feel difficult?

In reality, cross functional working is challenging because:

• teams operate under different pressures and success measures
• people use different language to describe the same issues
• roles and decision‑making authority are not always clear.

Too often, organisations expect collaboration without explicitly developing the skills required to do it well. People are left to navigate difficult conversations, competing priorities and conflict through trial and error.

From good intentions to real capability

Effective cross functional working does not happen by accident. It needs to be built deliberately.

This includes:

• clarity of purpose and shared outcomes
• intentional communication, not just more communication
• making time to invest in relationships: introducing teams early, understanding each other’s priorities, and recognising the value different functions contribute to the organisation
• psychological safety, so people can raise concerns and challenge constructively
• practical skills in influencing, listening and managing difference.

When these capabilities are in place, collaboration becomes more than a value statement. It becomes a way of working that supports better outcomes for people, teams and the organisation as a whole.

A final thought

In a world where challenges rarely sit neatly within one team, the ability to work well across boundaries is no longer optional. Organisations that treat cross functional working as a core capability – rather than a hope – are better equipped to deliver, adapt and sustain performance over time.

A recent case study from a cross‑functional working programme we ran with a client illustrates what this looks like in practice, and the difference it can make when collaboration is treated as a capability, not a hope.
