A time-bound project is constrained by hard deadlines. Since most time-bound projects start with more requirements than developers can handle within the imposed time constraints, requirements often must be slashed halfway through the project, resulting in missed deadlines, customer frustration, and wasted effort. Statistically Planned Incremental Deliveries offer an approach that addresses these problems by combining ideas from critical chain planning, incremental development, and rate monitoring into a practical method for planning and executing time-bound projects.
