In a sector increasingly defined by complexity, whether that’s the NDIS, aged care reform, or integrated health models, traditional evaluation approaches are starting to show their limits.
Many organisations are still relying on evaluation methodsdesigned for stable, predictable programs. But what happens when your model isevolving, your outcomes are still emerging, and the environment keeps shiftingbeneath your feet?
This is where developmental evaluation comes into itsown.
Developmental evaluation (DE), originally coined by MichaelQuinn Patton, is designed for innovation in complex, dynamic environments where the path to outcomes is not yet fully understood.[1]
Rather than judging success at the end (summative evaluation) or improving a known model (formative evaluation), developmental evaluation works alongside your program as it evolves. It provides real-time feedback, helping teams adapt, test, and refine their approach as they go[2].
It is, in essence, an evaluation approach built for learning, adaptation, and forward momentum.
And importantly … it assumes something many organisations already know but rarely design for:
You don’t always know what “good” looks like until you’ve started building it
From a consulting perspective, the real question isn’t what developmental evaluation is, it’s why it consistently leads to better results.
Traditional evaluation often happens at the end, when it’s too late to change course. Developmental evaluation flips this model by creating continuous feedback loops, allowing organisations to adjust in real time.
This means:
In practice, this reduces waste and increases the likelihood of achieving meaningful outcomes.
Many social and health programs operate in non-linear, unpredictable environments where cause-and-effect is difficult to isolate. Developmental evaluation is specifically designed for this context.
Rather than forcing a rigid evaluation framework onto a fluid system, it works with complexity—recognising that:
This adaptability is a major reason why DE is increasingly used in large-scale reform and system transformation.
At its core, developmental evaluation is about better decisions, sooner.
Evaluators work closely with program teams, analysing data as it emerges and translating insights into practical changes.
Instead of producing reports that sit on a shelf, DE produces:
This leads to more confident and responsive leadership.
Developmental evaluation is inherently co-creative. Evaluators don’t sit on the sidelines, they work alongside teams.
This has two powerful effects:
In other words, evaluation becomes part of the organisation’s culture, not just a compliance exercise.
Many organisations are under pressure to innovate, but their evaluation frameworks still penalise risk-taking.
Developmental evaluation changes that dynamic by:
It is particularly valuable when programs are:
Not all evaluators are equipped to deliver developmental evaluation well. In fact, it requires a different mindset, and a broader skillset, than traditional evaluation.
If you are commissioning an evaluation, here are some critical things to look for:
DE requires evaluators who are comfortable with uncertainty and able to adapt their approach as the program evolves.
Effective evaluation depends on meaningful engagement with staff, participants, and partners. Strong evaluators bring people into the process, not just extract data.
Developmental evaluators typically work closely with program teams, often “inside” the initiative rather than externally observing it.
While technically rigorous, DE is not rigid. Evaluators should be able to tailor methods (qualitative, quantitative, mixed) to suit the evolving context.
A good evaluation partner doesn’t just produce reports, they provide clear, practical recommendations that improve program delivery and outcomes.
The best evaluators combine analytical skills with strategic insight, helping organisations interpret findings and make confident decisions.
Across sectors, including disability, aged care, and health, organisations are facing:
These are not stable environments. They are evolving systems.
Developmental evaluation is increasingly recognised as a fit-for-purpose approach for pilots and new programs in these contexts, because it allows organisations to:
Put simply, it helps organisations stay adaptive while staying accountable.
If your program is:
Then traditional evaluation alone may not be enough.
Developmental evaluation provides a way to learn faster, adapt smarter, and ultimately deliver better outcomes.
As trusted and experience program evaluation experts, we work with organisations across the NDIS, aged care, and health sectors to design evaluations that do more than measure outcomes, they actively shape them.
If you’re:
we can help you embed a developmental evaluation approachthat drives real-time learning and better results.
