I believe the scope of requirements changes in Waterfall model is less than that in Spiral Model. In Waterfall model, you progress to the next stage only when the requirements of the stage above it are finalized and signed off. So litteraly we dont have any scope of changing the requirements once we move down the phases in this model.
However, Spiral model gives us flexibility to change the requirements and scope anytime during the life cycle.
In this model we implement the individual requirements following all the standard phases of Software Life Cycle. So if any new change is there, we can implement it in next version of the software.
The Hicks substitution effect keep utility constant rather than keeping pur- chasing power constant.
For original estimate approach it does not take into account for past cost performance for forecasting of future performance and only take original cost of work. Whereas revised estimate approach takes past cost performance as a good forecast indicator for future performance.
1. Cardinal Approach refers that you can calculate or Measure the utility (degree of satisfaction) Numerically, while According to ordinal approach you can not measure the utility numerically. 2. Cardinal Approach follow the Law of Diminishing Marginal Utility while Ordinal Approach follow the Indifference Curve. 3.Cardinal Approach Emphasis on units while ordinal approach is based on rank.

It matters by the approach you take. In the expenditure approach (C+I+G+NX) C or consumption is the largest part In the income approach, it is income given to labor In the value added approach, it is the difference between input price and output. note:all final GDP calculations arrive at the same value.
A difference is that with ordinal utility approaches, you cannot numerically measure the level of consumer satisfaction. With cardinal utility approaches, you can to an extent.

Waterfall
the difference is that a waterfall continues to move while a puddle stays still. the similarities are that they are both water. from:cecilia36

manoeuvre war fare and manoeuvrist approach
vitoria is a waterfall but the others are not.
Simple, It will be more oxygenated.

database approach
Revolution is for changing the whole; movement is for changing a part.
An approach = dealing with something Method = a particular way of doing something:
The RAD model, also known as the Rapid Application Development, is a linear software for creating prototypes. The Waterfall model is a sequential software.
