The term 'Progress Impeders' can be summarized as a group of obstacles that prevent progress from being made. The most common impeders are known as 'SNAGS', which are five-letter words that refer to any kind of hindrance or obstruction. SNAGS can range from physical barriers, such as a fallen tree blocking a road, to more abstract issues, such as a lack of resources or a disagreement between stakeholders. In any case, SNAGS can slow down or even halt progress, making them important to identify and address in order to ensure successful outcomes.
