Now, let's look at the practical essentials 2
2
of everyone's favorite subject, estimating. 3
3
First, let's try an exercise 4
4
that demonstrates that an estimate with any analysis 5
5
behind it at all can come surprisingly close. 6
6
For example, your mission is to estimate 7
7
the number of piano tuners in the city you live in. 8
8
You have no input information at all, 9
9
no consulting the internet. 10
10
How can you break down the analysis? 11
11
What is the estimate based on? 12
12
Pause the video, and give it a shot. 13
13
Now that you have structured the estimate, 14
14
how close do you think it actually is? 15
15
Imagine if you were able to research the estimate 16
16
and base it on some hard data, 17
17
can you see that estimates with any analysis 18
18
behind them can get very close?
