Helicoidal Models

DNA vs. Software Development

1. "Helicoidal” models for DNA dynamics

2. The Helicoidal Life Cycle - Software Development

1. "Helicoidal” models for DNA dynamics
Deoxyribonucleic acid (DNA) is the nucleic acid that contains the hereditary information used in the development and functioning of all living organisms. The total genetic information in a cell is called its genome.

2. The Helicoidal Life Cycle - Software Development

Ref.: The Helicoidal Life Cycle – A Tool for Software Development and Enhancement
by Antonio Carlos Pinto Dias Alves, Unidade Gestão de Riscos

"The Helicoidal Life Cycle allows superposition of different development phases, thus promoting saving time and costs. Although some phases can be completely superposed by others, each one can be tracked independently whereas the whole system development can be tracked by a separate helicoidal life cycle that covers the inner ones in an onion style. So, from the examples of use presented, we saw that reductions in development time and costs cannot be ignored. In some cases, those reductions reached almost 50%. May be, when CASE tools specifically designed for use with the helicoidal cycle be in use, savings can be even bigger."
