Explanation
The mechanism used here for projections is a unit cost and revenue model intended to show an envelope of outcomes for a process in which
money is spent to produce sales in a sequence of steps, each narrowing (or expanding) the number of customers,
encurring unit costs, taking amounts of time, and ultimately producing outcomes. The columns shown are:
| Step | This describes the step in the process. It is assumed that all steps must take place |
| Time (D/H/M/S) | The time (in Days / Hrs / Mins / Sec) to perform the step and total time through completion of this step |
| Min < Quantity > Max | The minimum, expected, and maximum number of customers reaching this point in the process. |
| $/ea | The cost per customer of performing this step (including the time costs). |
| Time/ea | The time spent (in Days / Hours / Mins / Sec) per customer for performing this step. |
| Min < Cash Flow > Max | The range of costs or revenue spent or received at this step. |
| Min < [D/H/M/S] > Max | The range of total time spent (in Days / Hours / Mins / Sec) to this step and total. |
| Success % | The expected rate at which customers at this step go on to the next step. |
| +/- | The likely variation in expected rate of customers going on to the next step. |
| Min < Left > Max | The range of the number of customers left after this step. |
| Note | This is a description of this step, with brief justification for the costs/revenue. |
Output is on the top, followed by the input section. For help, watch the video.
Add step: adds another row to the sieve.
Refresh: recalculates and redisplays updates.
Save: saves the current sieve for later loading.
Load: clears and the loads the last saved sieve.
Clear: empties the sieve so you can start again.

In each input row:
✓ OR ✗: This row is ✓ (or not ✗) shown and calculated in the output area
⛔: Deletes this row never to return, except if you Save it just before and then use Load
↘: Move this row down one (note recalculation of Quantity field becomes new input)
↗: Move this row up one (note recalculation of Quantity field becomes new input)
