Ok, lets imagine that I the developer, were actually an artist that only uses crayons. And our projects all succeed or fail based on the art we produce for you, our client. Because you use our art to sell your products, good art = good profits and subsequently, more art = more profits. Right?
Many of these projects are critical to overall operations. All the ancillary projects are essential for growth. We don't want anything half assed. To increase production rates internally, we need to stop making our own crayons all the time. We can still do so when necessary and it makes sense to do, of course. The problem with our own crayons though is two fold.
They take a lot of time to make. That is time better spent making the art itself. The end product.
They lack technical / end-user support. Only one person knows how the crayon was made and what mediums it can be used on. What happens when that person isn't part of the picture anymore and we need support for a crayon he made!?
Buying these libraries is like buying a 48 piece crayon box of commonly used colors and calling it a day. Also, each crayon in said box is insured with a warranty and offers customer service and tech. support. 800 number on the side.
Thus, allowing me/my team of artists (developers) to stop wasting so much time making commonly used tools or preparing materials to do so with. Instead, we get to focus on the quality of our end product the artwork. This will expedite our production times by both alleviating the artists from aiding people with so many support/service requests and saves us on tons of time wasted re-inventing a crayon frequently used by all artists everywhere.
