What are the main phases in a web application's lifecycle?
A web app moves through four phases — pre-project, development, deployment, and operations — and the cycle repeats as new features are added.
* A web app's lifecycle runs pre-project → development → deployment → operations, then loops back to development whenever new features are added. *
| Phase | Activities |
|---|---|
| Pre-project | Idea, rough concept, requirements |
| Development | Requirements, design, implementation, testing |
| Deployment | Deploy to production environment |
| Operations | Monitoring, maintenance, corrections, upgrades |
After deployment, the cycle often repeats for enhancements and new features. Operations includes log analysis, backups, and scheduled updates.
