The spiral model has two dimensions: _______________ and _______________?
Show answer Hide answer
Answer: C. radial, angular
Explanation
The spiral model uses radial dimensions to represent cumulative costs and angular dimensions for progress. These two geometric coordinates map out cost expenditure against project cycle progression clearly. Visualizing development cycles in polar coordinates helps track both financial investment and milestone completion. Polar coordinate systems plot points using distance from an origin and an angle of rotation. In software spirals, radius growth corresponds directly to increasing project expenses over time. Angular rotation tracks the passage through planning, risk analysis, engineering, and evaluation phases.
Project managers monitor radial cost expansion to ensure development stays within budgetary boundaries. Angular tracking ensures teams complete all necessary engineering phases during each iterative loop. Dual-dimension tracking provides a comprehensive view of project health and financial status simultaneously. Diagonal and angular dimensions do not accurately describe the standard polar coordinate layout of spirals. Radial and perpendicular terms misstate the rotational angle axis used in software process diagrams. Diagonal and perpendicular options fail to capture the standard terminology of spiral model geometry.
