Top-down methods were favored in software engineering until the late 1980s, [2] [failed verification] and object-oriented programming assisted in demonstrating the idea that both aspects of top-down and bottom-up programming could be used. Modern software design approaches usually combine top-down and bottom-up approaches. Although an ...
In 1988, Barry Boehm published a formal software system development "spiral model," which combines some key aspects of the waterfall model and rapid prototyping methodologies, in an effort to combine advantages of top-down and bottom-up concepts. It provided emphasis on a key area many felt had been neglected by other methodologies: deliberate ...
While the top-down orientation supports a horizontal team organization, bottom-up approaches try to provide generalized components or services, leading to a better user satisfaction. [4] The collaborative identification of goals introduced by GDP allows combining top-down with bottom-up aspects (“ top-down thinking and bottom-up acting ...
Design thinking is a creative process based on the "building up" of ideas. This style of thinking is one of the advantages of the designer and is the reason why simply employing one of the existing systems approaches into design, like, for example, systems engineering , is not found sufficient by the advocates of SOD.
Top-up Urbanism is the theory and implementation of two techniques in urban design: top-down and bottom-up. Top-down urbanism is when the design is implemented from the top of the hierarchy - normally the government or planning department. Bottom-up or grassroots urbanism begins with the people or the bottom of the hierarchy.

Compared with traditional top-down design approach, generative design can address design problems efficiently, by using a bottom-up paradigm that uses parametric defined rules to generate complex solutions. The solution itself then evolves to a good, if not optimal, solution. [9]
