Visual Management: send in the geeks!

"Visual Management": plain paper on the wall, with hand-built charts. For up to about 100 items a day, its ok to work with a pencil (provided the chart can be seen by the whole team).
You can "visualy manage" your daily activities, and follow their evolution. Very usefull (and sometimes disturbing)

Six Sigma: a method from the industry (and very popular nowadays in the IT Production) to eliminate defects. Works well with laaaarges figures (beatifull gauss curves with 1 million entries)...
