This document discusses using behavior analysis techniques to improve team programming practices. It identifies three common problems: no preparation which leads to small learning, static typists who do not switch roles, and some programmers not joining the mob programming approach. For each problem, it performs an ABC analysis of the situation, proposes a hypothesis for an intervention, and discusses measuring the results. The conclusion emphasizes that behavior analysis can help identify issues, test interventions to change behaviors, and continuously improve team practices through observation and adjustment.

Behavior Analysis

5. Behavior Analysis
One of the Psychologies, which focus on the behaviors. There
is a methodology to look for the factors which have effect the
behaviors throughout the experiments. In Behavior Analysis,
personalities and characters are not the reason why a person
can not do something.

Reinforcement：stimulus which strengthen the
behavior
Punishment： stimulus which weaken the
behavior
As consequence:
If reinforcement occurs, the behavior is
strengthen
If reinforcement disappear, the behavior is
weaken
If punishment occurs, the behavior is
weaken
If punishment disappear, the behavior is

35. How to use Behavior Analysis for Team
2020/01/08 RSGT2020 - Takuo Doi 35
1.Figure out the current situation using ABC analysis
2.Consider the intervention to change the situation
3.Observe the effect of the intervention
4.Figure out the situation again
NOTE: Some interventions does not work well
for some situations
