# Numbers simulation - less is more!

39,268 views

Published on

This is a little simulation that I have run numerous times. It shows in a very direct and apparent way that the less things we do at the same time, the faster each thing runs. In other words: Limit you WIP!

I like this exercise since it can be run by a single person or by many (64 is my record) and still get the message across.

This presentation is a simulation of the simulation, so if you click through the slides fast you get a little animation feature as well as timing.

### Numbers simulation - less is more!

1. 1. Numbers simulation A interactive demonstration Marcus Hammarberg
2. 2. Simulation goals • Three projects – Write letters: A – J, with blue pen – Write roman numbers: I – X, with red pen – Write numbers: 1 – 10, with black pen • Measure two times: – Time to complete each project – Time to complete all project • Run two times: 1. Row by row 2. Column by column
3. 3. ROW BY ROW RUN DOING ALL PROJECT AT ONCE Let’s try it
4. 4. Row by row - run A - J I - X 1 - 10 Time: “Clock”: 00:00
