Wherever we find creative people or the best technology we must not forget the thing that surrounds them all or were ideas will emerge, the working area or environment which works due to the space, facilities and comfort. So, enterprises seem to believe that if they've got the best equipment it won't matter were they use it but they are wrong, Pixar has even developed a special building in which the common areas seem to be centered, the place works like a circle in which you will inevitably encounter co-workers increasing relaxation and brain-storming when talking with others. On the other hand, facilities work an important part on creating the perfect environment, if we wan't to make people enjoy what they are doing we have to give them the sensation of being at home, in the Pixar way by providing them with cafeteria service, and other home-facilities needs which would led us to the third environmental factor which are facilities. They (Pixar) would secure you are having conferences in comforting chairs, rooms, even lighting and color's play an important role in creating the right and comfortable environment.
Already having the required environment we need to move on to the people that would be using it but recalling that in the Pixar way they do not call them workers but family due to the process which enables them to do so. Pixar works over the principle that in order to secure workers work and confidentiality camaraderie works ten times better than creating confidentiality restrictions via contract. They would using their environment (which already makes them feel at home) manage to overpass even this camaraderie part by making people bond in a level of respect and friendship in which teams of work would evolved into friendship gatherings in which the best ideas would always raise and even more important than ideas are ways to secure that when the idea is ready people won't feel intimidated to point out which are the parts that need to be improved in the Pixar way by keeping complete confidentiality whenever gatherings are held sending replies via mail and by making everyone feel part of the process, even workers that are not closely related to the part of the process Pixar is working on, they would be able to attend conferences and give out their point of view.
Finally, what Pixar takes mostly in account and what would secure that stories change and keep audiences from all ages keeping attention to what's happening is their creativity view which would form part in every aspect of the movie and not just the principal elements. Creativity would need to be enrolled in the way the movie is promoted or even the extra elements it contains and by assuring a way to make people relate to what they are watching. From a Pixar's view talented people are not those that out stand due to their abilities but rather those who out stand due to their hard work, their ability to transform even the worst idea into something good or come up with a new and better one, the most important quality being letting people think freely and teaching them to stop being afraid of thinking wide, that's why most of the great ideas never come out to see the light, and that's why Pixar creates even "schools" in which new-comers are teach those values and protocols to be able to secure a place in the "family".
In conclusion, Pixar's recipe to success has being able to maintain the star-system alive due to their view of the company as a live organization that would be able to overcome obstacles due to their people's creativity, their relationship record and their comfortable environment making it clear for common studios that the system is not the problem but rather the way we see it or manage it is, and as Ed Catmull says "Pixar does not rules under this operating principles, but rather see them as a way of life".
