The Wendrzycki Formula

Todd O. Cronkhite Maine Native, Presently Away

>Had a phone conversation with Ray Wendrzycki the pother day, and we got talking about time estimation for remodelling projects. He said that his wife had come up with a formula that has proved to be quite accurate. It works like this:

Estimated Time To Complete 6 months

Now TRIPLE that estimation =18 months

Now move the months to the next higer level, which of coarse would be Years.

So in the above example the Time Required to finish a 6 month project works out to 18 YEARS!

So, just to reinforce the Wendrzycki Formula a one week estimation would be:

1 week, x 3= 3 weeks, take 3 weeks, move weeks to next higher level = 3 months!

Boy, does this answer a lot of questions!, and without knowing it I belive that I have proven this formula to be in fact quite accurate. :~(

Now, I also believe that this formula can be applied to Costs as well, tho I haven't got conclusive evidence of it yet.

Cost is much simpler...

>Actual cost always seems to end up being the bid price, leaving no profit!

That applies to contractor cost estimation

>but for the weekend warrior, cost is roughly the cost estimated at the beginning of the project, cubed.

Must use Post-It notepad when figuring out Formula

John Aniano, in central NJ...

>Todd,

As per Raymond's explicit instructions, you MUST use a Post-It note on which to do your mathematical figuring for the "Wendrzycki Formula", otherwise, the numbers won't work out correctly.

If you doubt me, you should ask Raymond directly. Trust me on this one. Really.
