|The Dutch government is reintroducing policy for the 20 National Parks. The aim is to develop the National Parks into a strong brand. The reason behind it is the claim that a National Park contributes to the regional economy. There is a clear need from the managers of National Parks to understand how that contribution works. Insights from the external factors, combined with information about its current users and stakeholders and market research data will help the manager, but also local enterprises to choose relevant target markets. There is therefore a need for the development of a tool that brings the benefits of a National Park in a simple, affordable and reliable manner. The tool consists of Key Performance Indicators (KPI). Key Performance Indicators will determine how well the National park is meeting its objectives (Wearing & Schweinsberg, 2016).
