A Project Sponsor is vital to ensure a major infrastructure project is successfully delivered. Project Sponsors focus on benefits and strategic outcomes so that investments become money well spent. Key responsibilities include managing the expectations of all stakeholders and keeping the organization and the project team focused on realizing the project’s intended benefits.

What is a Project Sponsor?

A Project Sponsor is a person accountable for the success of a project. They are the guiding mind and project champion who aligns the project with strategic objectives, funding and stakeholder needs.

Project Sponsors advocate for the project outcomes, manage stakeholders, promote the benefits, and often manage internal and external politics. They hold commercial, governance, and assurance accountabilities alongside business case and ownership of the project’s benefits.

It’s good to distinguish Project Sponsors or Project Sponsorship from Project Management.

Organizations may think of a Project Sponsor as a senior executive in charge. While executives often have a role in mobilizing people, resources, and making decisions, they usually do not at their level have the time to effectively do what a true Project Sponsor needs to do, or is good at.

Why should major projects have a project sponsor?

Infrastructure projects perform better with Project Sponsors. They help projects run smoothly and ensure benefits are realized by performing the following essential roles:

Key responsibilities of a Project Sponsor:

Navigate the politics for infrastructure development
Understand external and internal stakeholders
Manage expectations
Maintain transparent communication
Lead a strategic vision for the project
Manage and mitigate risks
Mitigate negative social and environmental impacts
Ensure timely project delivery

1. Navigate the politics of infrastructure development

Infrastructure projects are political, particularly major projects and megaprojects. Whether you need consent to take land, property, or to carry out work in public spaces, permission is generally required to undertake disruptive activities.

Project Sponsors interface with the public either through public realm, or by the services they provide upon completion of the projects (in sectors like water supply, energy, health, education and transport).

Projects involve complex commercial agreements to fund or finance infrastructure. Economic and geopolitical politics can play an influential role in securing funding and influencing the availability and cost of financing. Project Sponsors often make the business case, secure the funding and the terms on which it is offered. Knowing the political context, socio-economic conditions and key stakeholders is as crucial as understanding the need for the project and benefits which will be delivered.

2. Understand internal and external stakeholders

External stakeholders

The success of a project hinges on effective collaboration among various stakeholders, including government bodies, local communities, private businesses, and advocacy groups. Project Sponsors excel in fostering these collaborations, acting as intermediaries between differing interests.

Through comprehensive stakeholder mapping, Project Sponsors identify the right people and groups, understand their concerns, and develop communication strategies to address and incorporate their input. This proactive approach helps build consensus, ensuring that the project aligns with the broader societal and economic goals.

Internal stakeholders

Operational staff and teams have at times been let down by previous handovers of incomplete or poor-quality projects. These are the maintainers and operators, who often work under pressure, and might have been able to prevent those issues if they had been consulted and had the time to answer.

Project Sponsors play a crucial role in understanding their needs and factoring them into the project scope, business case, and plans. Operations must be a key facet of project planning and design. Making Project Sponsors accountable for that helps improve project outcomes

3. Manage expectations

Stakeholders have high expectations of what projects can do for them, often paired with a low tolerance for disruptions caused by project delivery. With limited knowledge or experience with change management in a regulated environment, an expectations management crisis could result.

Project Sponsors help explain the art of the possible and balance it against the art of the sensible.

4. Maintain transparent communication

Communication is a cornerstone of successful stakeholder engagement and management. Project Sponsors facilitate transparent and consistent communication through various channels, keeping people and groups informed about project developments, timelines, and potential disruptions.

This ensures that concerns are addressed promptly to foster a sense of trust among stakeholders. Project Sponsors ensure that there are no surprises resulting from failure of reporting or a culture of denial.

5. Lead a strategic vision for the project

Project Sponsors act as visionary leaders who define a project’s objectives, scope, and long-term impact. By keeping focus on the strategic vision and reminding everyone of the benefits, Project Sponsors keep the bigger purpose of the project alive.

Equally crucial is their ability to secure funding, a task that demands intricate financial acumen and a deep understanding of the economic landscape. With the financial backing provided by Project Sponsors, projects can overcome budgetary constraints and move forward with confidence.

6. Manage and mitigate risks

Risks are inevitable with large-scale infrastructure development. Project Sponsors specialize in strategic risk management, identifying potential pitfalls and formulating strategies to mitigate them. Their expertise in anticipating and addressing challenges helps create a more resilient project framework, reducing the likelihood of delays and cost overruns. They understand which of the project players is best placed to hold which risks. In a market which is seeing more collaborative and progressive contracting models, this knowledge is vital to securing value.

7. Mitigate negative social and environmental impacts

Infrastructure projects often have a significant impact on local communities and the environment. Project Sponsors take a holistic approach to manage these impacts responsibly. By conducting thorough impact assessments, Project Sponsors can implement mitigation measures and community engagement programs that address concerns and contribute positively to the local landscape.

8. Ensure timely project delivery

The timely delivery of projects is paramount to their success and impact. Project Sponsors focus on establishing realistic timelines, setting milestones, and closely monitoring progress. Their proactive approach to project management and scope control helps prevent delays and ensures that the benefits of the infrastructure are realized sooner rather than later.

Project Sponsors help deliver better projects

Project Sponsors are indispensable for the delivery of successful infrastructure projects. By combining their strategic vision, financial acumen, regulatory expertise, risk management skills, and stakeholder engagement capabilities, they contribute to the seamless execution of these complex undertakings. They focus on benefits and strategic outcomes so that investments in infrastructure become money well spent.
