Integrated design is a comprehensive holistic approach to design which brings together specialisms usually considered separately. It attempts to take into consideration all the factors and modulations necessary to a decision-making process. A few examples are the following:

The requirement for integrated design comes when the different specialisms are dependent on each other or "coupled". An alternative or complementary approach to integrated design is to consciously reduce the dependencies. In computing and systems design, this approach is known as loose coupling.

Three phenomena are associated with a lack of integrated design:

A committee is sometimes a deliberate attempt to address disparate design, but the phrase "design by committee" is associated with this failing, leading to disparate design. "Design by committee" can also lead to a kind of silent design, as design decisions are not properly considered, for fear of upsetting a hard-won compromise.

The integrated design approach incorporates collaborative methods and tools to encourage and enable the specialists in the different areas to work together to produce an integrated design.

A charrette provides opportunity for all specialists to collaborate and align early in the design process.

Human-Centered Design provides an integrated approach to problem solving, commonly used in design and management frameworks that develops solutions to problems by involving the human perspective in all steps of the problem-solving process.
