It's usually not enough time for improving comfort of code writing and product monitoring. But this is an important thing for making software products with high quality. IT society even made awesome tools for making our life easier and culture of software engineering continue growing.

1. Software Engineering Culture:
Improve your Code Quality.

That complex whole which includes
knowledge, belief, art, morals, law, custom
and any other capabilities and habits
acquired by man as a member of society.

8. CODE CONVENTIONS
A set of guidelines for a specific programming
language that recommend programming style,
practices and methods for each aspect of a piece
program written in this language.

Spaghetti code is a bad practice.

9. AUTOMATED TESTING
- Unit testing;
- Integrating testing;
- System testing;
- Performance testing;
- Other testing...

Problems we need to solve:
➔ retain few latest versions of our
product;
➔ retain history of changes;
➔ possibility to work in parallel;
➔ possibility to rollback some changes;

16. CODE ANALYSIS
16
Problems we need to solve:
➔ keep code clean;
➔ argumentative measures of our code;
➔ fast and automated code analysis;
➔ track history of our code measures.

18. CODE ANALYSIS - Our Solution
Use SonarQube for Continuous Inspection.
Run code analysis during night builds.
Make KPI for code improvements monthly (metrics
and value that we need to improve during the
month).

26. Problems we need to solve:
➔ monitor health of our application on
different layers and aspects;
➔ collect information about specific
nuances about our functionality;
➔ analyze collected information in
comfortable way.
