The ecosystem implied by the web performance is large

This is not a secret. Web performance is one of the most important goals of every web site whatever their kind : e-commerce, institutional, information… In fact, this is a shared goal by several profiles to satisfy the user :

• Product owner : A web page must be loaded as quick as possible so that the users can start to interact with and turn into customers.
• SEO manager : A lightweight page helps to get better visibility in Search Engines such as Google, Bing…
• User : A web page takes too much time to load ? Well, the user doesn’t wait and visits the other competitors of the market.
• Support service : They really don’t want to receive users emails reporting the web site / app is unusable due to its heaviness.
• CTO : This is him which will be responsible in the sight of the CEO if the web page are too slow and they loose money.
• CEO : I don’t think he’s happy when competitor CEOs make fun of him telling how slow are his web site.
• Web performance actors : They offer tools to measure the perfomance of the web page / app.
• and the Front-End developer : He is the cornerstone between the previous profiles. He must make its best to make everybody happy.
