The Hidden Cost of Poor Stakeholder Engagement in Complex Projects

In complex projects, the biggest risks are often not technical. Organisations can invest heavily in strategy, systems and organisational design, but without effective stakeholder engagement, even the best solutions can fail to deliver their intended outcomes. Research from organisations including the Project Management Institute (PMI), Prosci and the Australian Public Service Commission consistently shows that stakeholder engagement is a critical factor in successful project delivery, organisational change and long-term adoption.

The hidden costs of poor stakeholder engagement

Poor stakeholder engagement often becomes increasingly visible as a project progresses; when decisions need to be revisited, there is a risk that implementation can lose momentum, trust isn’t built or key people will become less engaged. These costs are not visible on a project plan, but they can impact delivery, adoption and long-term success.

For example, a lack of stakeholder engagement strategy can cause organisations to miss critical operational insights. Though the solution may be technically sound, if it’s difficult to implement in practice because it doesn’t reflect how people work, what they need or the constraints they face, it may not be adopted as quickly as planned for. It can lead to additional consultation, delayed approvals and reduced confidence.

It can also increase resistance. When stakeholders feel decisions have been made without them, they are less likely to support the change or advocate for it within their teams. In complex environments, this can slow momentum and place additional pressure on leaders who then need to spend time rebuilding trust, addressing concerns and explaining decisions after the fact.

The cost of poor stakeholder engagement cannot only be measured in budget or time but also by reduced adoption, fragmented communication, missed risks and lost opportunities to build alignment. In many cases, the investment in engaging stakeholders early will be far less than the cost of repairing trust, correcting misunderstandings or redesigning solutions later.

By explaining what the team knows, what it doesn't know, and what comes next, stakeholders become partners in solving challenges rather than observers waiting for updates. – PMI, July 2026

Why early stakeholder engagement matters

At Elysium EPL, we've seen the value of meaningful stakeholder engagement across major transformation programs. When the Royal Australian Navy faced a significant increase in the tonnage and complexity of its fleet, Elysium EPL was brought in to create a new organisational design that would allow for greater efficiency and quicker adaptability. A key part of this process was stakeholder engagement. Stakeholders were identified early, mapped according to their influence and interest, and engaged through workshops, communication planning and co-design activities. By establishing positive and productive relationships with stakeholders early, and keeping them updated, the team was able to quickly develop process maps, responsibility boundaries and enabling systems in a collegiate way.

Similarly, our Transformation, Engagement and communication team supported the Murray-Darling Basin Authority’s (MDBA’s) MD-WERP program in developing a suite of products to ensure MDBA policy makers could use the program’s output for years to come. The project faced two challenges:

1. Limited cross-theme collaboration and integration put the project at risk of not reaching its objectives.

2. Scientific language and research were difficult to access for a broad range of audiences.

To design the final communication products, the team engaged directly with policymakers and end users to understand how research findings would be used in practice. By designing communication products and a knowledge repository around stakeholder needs, valuable research outputs were preserved and made accessible for future decision-makers. Without this engagement, critical knowledge risked being lost as staff moved on from the program.

The common lesson across these projects is simple: people support what they help create. Effective stakeholder engagement is not a communications activity that occurs after decisions are made; it is a strategic capability that informs better decisions from the start to support successful implementation.

Understanding stakeholders

Stakeholder engagement starts with identifying and mapping stakeholders and creating an engagement plan. The plan should:

• identify who is affected, influential or accountable

• understand stakeholder needs, risks and concerns

• involve the right people early enough to shape the solution

• use engagement insights to inform decisions

• maintain communication throughout delivery, not just at launch.

By committing to a strong stakeholder engagement plan and proper stakeholder communication, leaders benefit from faster decision making, transformation adoption and operational readiness.

“Engagement is not a soft skill, but a professional craft that requires continuous learning, reflection, and improvement,” says Laura Redman, Business Unit Lead for Elysium EPL’s Transformation, Engagement and Communication team.

“Organisations often think they are ‘doing engagement’ because the box is being ticked: sending updates, hosting sessions, gathering feedback. But true stakeholder engagement goes deeper. It’s about listening with intent, creating space for diverse voices, and building relationships that can withstand complexity and change.”

Invest in your stakeholders

At Elysium EPL, we believe successful transformation happens when people are placed at the centre of change. Importantly, stakeholder engagement is not treated as a one-off activity or ‘shelfware’; engagement plans are living documents that are regularly reviewed and refined in response to stakeholder feedback and changing project needs. This ensures they remain practical, relevant and aligned to successful delivery. This investment helps reduce risk, strengthen collaboration and create outcomes that are sustainable and supported by the people they impact most.

If you are planning transformation, organisational redesign or a complex project delivery, stakeholder engagement should be considered from the outset. Our experts can help build a structured engagement approach that reduces risk, builds trust and delivers lasting outcomes. Contact us to discuss a tailored stakeholder engagement approach.

Because ultimately, projects don't deliver outcomes - people do.

FAQ

1. What is stakeholder engagement?

Stakeholder engagement is the process of identifying and working with the people who can influence, are affected by, or have an interest in a project. It involves communicating, listening, gathering feedback and building relationships to ensure stakeholders understand and support the project's objectives.

2. What is stakeholder mapping?

Stakeholder mapping is a tool used to identify stakeholders and assess their level of influence, interest and impact on a project. This helps understand who needs to be engaged, their level of interest, when they should be involved and the most effective way to communicate with them.

3. Why is stakeholder engagement important for transformation projects?

Transformation projects often introduce significant change, making stakeholder support critical to success. Effective, early engagement helps organisations understand stakeholder needs, address concerns early, build trust and increase adoption of new ways of working by taking them on a journey that takes their concerns and impacts into account.

4. What are the risks of poor stakeholder communication?

Poor stakeholder communication can lead to confusion, resistance to change, project delays and reduced confidence in the project. It may also result in missed risks, duplicated effort and lower adoption of project outcomes, increasing the cost and complexity of delivery.

5. How does stakeholder engagement support project delivery?

Effective stakeholder engagement helps projects make better decisions, identify risks early and build support for implementation. By ensuring the right people are involved at the right time, organisations can reduce resistance, improve collaboration and increase the likelihood of achieving successful project outcomes.
