Complexity
Complex situations involve predictable events that are challenging to manage due to numerous interactions. Examples include building a house, assembling an airplane, or developing an inventory management system. These projects involve many stakeholders, leading to coordination challenges and mismatched skill sets.
The best way to handle complexity is to simplify. Although this may seem obvious, it is the most effective strategy. If it’s unclear who is responsible for specific tasks, break the process into smaller tasks and define clear areas of responsibility. For large development estimates of crucial components, break them into smaller sections or set milestones to improve certainty. In my experience, the less defined a task or scope, the higher the estimate. Identifying areas with the highest estimates and examining their scope clarity is a good place to start.
