Backlogs can occur due to multiple reasons: - Resource Constraints: Limited resources, whether financial, human, or technological, can lead to the accumulation of unfinished tasks. - Poor Planning: Inadequate business planning and unrealistic timelines can cause delays and build up backlogs. - High Demand: A sudden surge in customer demand can overwhelm the company's capacity to deliver, resulting in a backlog. - Operational Inefficiencies: Ineffective processes and lack of automation can slow down workflow, causing tasks to pile up.
