The Hague & Partners Convention Bureau’s research highlights lack of robust event legacy measurement

In a recently published white paper, exploring event legacy, it was revealed that choice of legacy and its subsequent measurement can be a challenging task for associations and not-for-profit organisations looking to leave a positive impact on society.


Recent research (https://bit.ly/42PtNPL) on event legacy showed that legacy goals are high-impact and far-reaching, and they should be driven by the associations and not-for-profits organising the events rather than being an add-on by the destination. However, measuring such legacy can be a significant challenge since it is long-lasting, and the time frame for success can vary from weeks to decades or even centuries.


“According to the research, 40% of the respondents working to achieve a legacy don't currently measure the impact, and 33% use surveys of event attendees, while 14% base success on event attendance levels. These measurements are valuable, but they are not focused on legacy,” comments Bas Schot, Head of Convention Bureau.


During the research, attendees debated and answered questions on the difference between outcome and legacy, and it was clear that legacy is not just about event activation but long-term communication and advocacy from associations and not-for-profits across all of their activities. Legacy goals can be challenging, far-reaching, and take a long time to achieve. Therefore, when it comes to events and a desire for legacy, there should be a focus on measurable outcomes that can add incremental value to an organisation’s overarching strategic goals.


Bas Schot continues: “The research highlighted the limitations of current measurement tools, and it was clear that measurement is only possible if clear goals are set in the first place. Key performance indicators and long-term strategic plans should be created at an organisational level rather than looking at an event in isolation. These, should feed into an event’s strategy and any event legacy program, which can be reflected on over time.”


“The research also showed that even with overarching strategic goals in place, long-term measurement can be a challenge, especially when legacy is focused on the education of individuals. Success in this area might only be achieved through incremental changes that can be too small to measure, but over years, they add value and knowledge to not just one person but a whole sector - and that, in time, creates a global impact,” concludes Bas Schot.


The research was conducted in two stages – quantitative research via a workshop with 11 leading international association conference professionals and quantitative survey data gathered from 70* event professionals from around the world.
