Research in the software industry on the cone of uncertainty stated that in the beginning of the project life cycle (i.e. before gathering of requirements) estimates have in general an uncertainty of factor 4 on both the high side and the low side. [3] This means that the actual effort or scope can be 4 times or 1/4 of the first estimates.

Cone of depression occurs in an aquifer when groundwater is pumped from a well; Cone of uncertainty, used in project management to describe the evolution of the amount of best case uncertainty during a project. Hertzian cone, the cone of force that propagates through a brittle, amorphous or cryptocrystalline solid material from a point of impact
The cone graphic shows the areas that will potentially be affected by Hurricane Ian. What does a ‘cone of uncertainty’ mean? What to know about a Hurricane Ian descriptor
Condition 2 means that X is a non-branching simplicial complex. [4]Condition 3 means that X is a strongly connected simplicial complex. [4]If we require Condition 2 to hold only for (n−1)-simplexes in sequences of n-simplexes in Condition 3, we obtain an equivalent definition only for n=2.
The cone over a closed interval I of the real line is a filled-in triangle (with one of the edges being I), otherwise known as a 2-simplex (see the final example). The cone over a polygon P is a pyramid with base P. The cone over a disk is the solid cone of classical geometry (hence the concept's name). The cone over a circle given by
The cone of uncertainty used by the National Hurricane Center has shrunk dramatically since 2003 as forecasting science improves. Every year, it’s recalculated based on tracking errors from the ...
