What I’m going to talk about?

Deploying a project is more than the deploy process

The project

What do we want to build?

There are different types of projects

Big projects

Small projects

The projects can be really different

But all of them have something in common:

We have to ensure the quality

The materials

Setting up a good structure

What do we use is important

How do we use them, is important too

We have to use the best tools we have

We need to know how to use them

The process

Doing it in the correct way

Even when we have the best materials

And when we use them correctly

A project can end up badly

Doesn’t matter how big the project is

The project fundations

Tools and good practices
