Software Development Lifecycle (SDLC)
The process used by the software industry to design, develop, and test high-quality software. It encompasses phases from requirement analysis to deployment and maintenance.
Impact
The SDLC enforces discipline. Without it, coding is just hacking.
Weinto take
The traditional SDLC is linear (Waterfall). We use the DevOps Loop. It's not a line; it's an infinite loop of Plan -> Code -> Build -> Test -> Release -> Deploy -> Operate -> Monitor -> Plan. There is no "end" to the lifecycle until the software is deleted.
