Quality definition

Two points of view:

● quality for the client

● quality of the code

But what's really matter

quality of design

Quality for the client

● change anything on the site without developer efforts

● create page, add link, upload image or file

● change title or meta description on any page

● change translations (multilingual sites)

Or, just change anythingalmost

Quality for developer

● conventions and standards○ Python code

■ PEP8■ Pyflakes checks■ PyLint etc.

○ JavaScript code■ Jshint■ Well organized code, naming convention

○ HTML W3C

● Tests: acceptance, unit, integration, UI

● We have tons of useful third-party apps to achieve quality for the client

● You should follow standards if you consider yourself as good developer

● If you're lead dev, convince your team members to follow standards

It's impossible hard but

If code clean it's easier to solve

real-world design issues

Also,

If you don't have backups of your database then probably

your code will suck in the future. For the client.

Performance

Thoughts

● Most of developers like to play with performance

● Typically performance bottleneck is not related to what they play with

If possible to improve performance by additional hardware

do it,

hardware is much cheaper than dev's time

How to improve performance

Development strategy

Business-critical/UX: registration, authentication, purchase process etc.

Business-critical data validation and consistency

Metrics and visibility

Enhancements
