Frameworks are not always the best solution
(The match between library and framework is not yet finished)
When i look back at my career since 2001 where i have done my first commercial website for a company - a video game company based in Paris, Delphine Software International -, to now, i was project manager of 62 professionals projects from any scale, and any timeframe
On top of this 62 projects in 18 years, I have 2 majors big failures on my list and this 2 failures was based on a IT "core" framework used.
