Throughout the entire project lifecycle, various undesirable events may occur, affecting internal and/ or external stakeholders. These events can be categorized for example into process-related and technical product-related ones.

• Process-Related Undesirable Events:
  These refer to disruptions or deviations in project execution and collaboration: Project progress deviates from the planned schedule or effort estimates. Resources, including personnel, are unavailable when needed. Commitments made by development partners are at risk of not being fulfilled.
• Technical Product-Related Undesirable Events:
  These concern the quality and suitability of the delivered product: Defective product is delivered to the customer. Requirements are incomplete or missing and therefore the product does not provide the needed capabilities. Changes in the product lead to unintended impacts on product's behavior.
