The Challenge: Why Outputs Alone Aren’t Enough

In Western Australia, public projects are often judged by the traditional measures of success: delivered on time, within budget, and in scope. But project managers know that’s only half the story.
The true challenge is ensuring projects deliver long-term value. Whether it’s a cycling trail, a rail line, or a major road, the question is: How will this investment improve lives and communities well into the future?
That’s where a shift in mindset is needed — from delivering outputs to enabling outcomes, value, and impact.
From Outputs to Outcomes to Impact
A simple framework developed by Zwikael and Huemann (2024) helps: Outputs → Outcomes → Value → Impact.
- Outputs: What the project delivers (a new road, a trail network, a rail extension).
- Outcomes: What changes when people use those outputs (safer journeys, shorter commutes, more visitors).
- Value: The net benefit of those outcomes, positive or negative, for stakeholders (e.g., reduced costs, new jobs, improved health).
- Impact: The enduring difference at a community or societal level (regional growth, stronger social cohesion, environmental gains).
For projects to deliver lasting public value, every link in that chain must hold. Without clear outcomes and a plan to turn them into value, even a well-delivered output risks underperforming.
Setting Benefits Early — and Getting Them Right
Research and practice show that early benefit definition is critical. Effective benefit targets should be:
- Specific – Clear, measurable, and linked to outcomes.
Example: “Reduce truck travel time between Esperance and Ravensthorpe by 10% within two years” instead of “improve connectivity.”
- Attainable – Ambitious but realistic.
Overpromising undermines credibility; benefits must be backed by practical strategies.
- Comprehensive – Covering financial, social, and environmental dimensions.
Projects like Collie’s transition from coal show how economic, community, and environmental benefits can be built in together
Keeping Delivery Aligned to Benefits
Defining benefits is only the start. Sustaining alignment through delivery requires:
- Governance: Clear oversight that regularly tests whether outcomes are still on track.
- Ownership: Named accountability for each benefit so they don’t “fall through the cracks.”
- Benefits reviews: Ongoing measurement and adjustment, not just at project closure.
This “golden thread” — from outputs to outcomes to impact — keeps the project’s purpose in view even when delivery pressures mount.
WA Examples: Public Value in Action
- Collie Adventure Trails: A $10m investment in mountain bike and bushwalking trails defined early goals — attract tourists, create jobs, support transition away from coal. The result: increased visitors, new businesses, stronger community identity.
- WA Bicycle Network Expansion: Active transport infrastructure is delivering safer journeys, healthier communities, and reduced emissions. A reminder that social and environmental benefits matter alongside economic ones.
- METRONET: Perth’s largest transport investment was framed explicitly around long-term outcomes like urban renewal and congestion reduction. That clarity built political and community support through disruption.
- Tonkin Highway Extension: A billion-dollar road project balancing freight efficiency with local amenity, community safety, and thousands of local jobs — proving that diverse benefits can be aligned from the outset.
The “So What?” for Project Leaders
If you’re leading or sponsoring projects in government, not-for-profit, or regulated sectors, here are three practical steps to strengthen long-term public value:
- Start with clear benefits
- Define specific, measurable, attainable, and comprehensive benefits at project initiation.
- Engage stakeholders early to capture multiple perspectives.
- Embed benefits in delivery
- Treat benefits as a live reference point, not a static document.
- Build regular reviews into governance processes.
- Assign accountability beyond delivery
- Make sure someone owns benefit realisation after the ribbon is cut.
- Track and report on outcomes for years, not just months, after completion.
Conclusion: A Mindset of Long-Term Value
Expanding the definition of project success means asking not only “Was it delivered?” but “Does it endure?”.
By setting the right benefits, aligning delivery, and staying accountable for outcomes, WA projects can achieve more than outputs — they can deliver lasting public value that strengthens communities, economies, and environments for generations.
That’s the impact worth striving for.
