# Workshop

### Objectives :

* Understand how to fix technical debt with Code Analysis.

## Connection - 10'

In pair answer to those questions, in your team :

* What is technical debt ?
* What is the difference between technical debt and legacy code ?
* How do you quantify your technical debt ?
* How do you use your Static Code Analysis tools ?
* What could be improved ?

#### Collective debriefing - What are your findings ?

## Conclusion - 10'

There is so much more to do with what we already have.

* Run analysis through :

```bash
sh run-analysis.sh --projectName=<project> --repositoryPath=<path>
```
