If you've done any sort of formal training, or first year university IT or business classes, you may be familiar with the quality triangle. The quality of a product depends on your ability to balance the factors at each point of the triangle - Time, Scope, Budget.
For us UX designers we work in a different triangle which I'd like to introduce - the triangle of needs.
UXers need to balance the business needs, the user needs and the tech needs. The inside of the triangle is the "needs", or the requirements / stories for the Product to be built.
