|
|
|
- Software industry and overtime
|
|
|
|
- The true purpose of overtime is to improve the quality of work rather than to handle the volume of work.
|
|
|
|
- Clearly avoiding a bad office environment, but no one is doing anything about it
|
|
|
|
|
|
|
|
- Improving the office environment is not an environmental problem, but a human problem
|
|
|
|
- It is possible to approach people who have authority to improve the environment (= "equipment police")
|
|
|
|
- This chapter: Why do we have to face off against the "Equipment Police"?
|
|
|
|
- Next chapter onwards: How to develop an advantage in "Confrontation"

### Programming Contest Experiment
|
|
|
|
|
|
|
|
- Programmers selected from each company competed for coding and testing time and remaining defects
|
|
|
|
- Feature 1: Each team fights in pairs against other teams, and at the same time, team members fight against each other
|
|
|
|
- Feature 2: Each participant uses the same work environment as usual at his work place during normal working hours
|
|
|
|
|
|
|
|
- The variation in the work ability of individual programmers was very large
|
|
|
|
- The measurement value of the best person is about 10 times that of the worst person
|
|
|
|
- The winner measures about 2.5 times more than the average programmer
|
|
|
|
- The mean measurement value of the top half is more than twice the mean of the bottom half
|
|
|
|
- Things that have nothing to do with productivity, things that have little to do with it
|
|
|
|
- programming language
|
|
|
|
- years of experience
|
|
|
|
- Number of remaining defects
|
|
|
|
- annual income
|
|
|
|
|
|
|
|
- **Who you teamed up with** was a factor in improving productivity
|
|
|
|
- Two people working under the same "corporate culture" have almost the same productivity
|
|
|
|
- Rules of thumb for individual variability may not apply
|
|
|
|
|
|
|
|
```
|
|
|
|
I can understand that the programmer's ability difference is 10 times,
|
|
|
|
There is a 10-fold difference in the productivity of the company itself

|
|
- The correlation between office environment and contest performance was quite remarkable

>Precisely, this data alone does not prove that better offices are more productive. ……
|
|
|
|
>If our hypotheses are proven correct, the dereliction of duty in designing and improving the office environment is clearly wrong.
|

|
|
|
|
|
→ If employees work more overtime, we should focus on why overtime work increased rather than reducing overtime work, and pay attention to the relationship between the office environment and productivity.
|
|
|
|
→ This is the reason why we have to "confront" the "equipment police"
