Which model is a variation of the waterfall approach where phases overlap instead of occurring sequentially?

Which model is a variation of the waterfall approach where phases overlap instead of occurring sequentially?

• A. Sashimi Model
• B. Ford assembly line
• C. The Phoenix Project philosophy
• D. Max Weber's bureaucracy

Answer: (A)

Overlapping phases in a traditionally sequential process allows pieces of work from different stages to progress at the same time, enabling earlier testing and feedback. The Sashimi model uses this idea by slicing the project into thin, overlapping layers so design, development, and testing can run in parallel to some extent rather than waiting for one complete phase to finish. The name evokes sashimi, where thin slices are served in quick succession rather than waiting for a whole block to be prepared. The Ford assembly line is a mass-production concept focused on a continuous flow of manufacturing steps rather than overlapping software development phases. The Phoenix Project philosophy centers on IT project management and throughput improvements, not a formal phase-overlapping development model. Max Weber's bureaucracy describes organizational structure and authority, not a software lifecycle approach.
