Performing analysis before development is important because it helps understand requirements, minimize errors, optimize cost and time, align with stakeholder expectations, improve design and architecture, and mitigate risks.

Designing architecture is important because it organizes the system, enables scalability and flexibility, optimizes performance, promotes modularity and reusability, enhances maintainability and extensibility, and ensures security and resilience.

Choosing the right technical stack is important because it ensures compatibility, enhances developer productivity, improves system performance, supports scalability, provides community support, and enables long-term maintenance and upgrades.

The main aspects of high-quality development include robust functionality, clean code, performance optimization, scalability, testing and quality assurance, security considerations, user experience, and documentation.

The main aspects of testing include test planning, test design, test execution, defect management, regression testing, performance testing, security testing, test documentation, test automation, and continuous improvement

The main aspects of launching an application include deployment planning, release management, data migration, performance testing, monitoring and support, user training, marketing, feedback collection, and post-launch maintenance.

The main aspects of maintaining an application include bug fixes, performance optimization, security updates, compatibility, user support, version control, testing, documentation updates, performance monitoring, regular maintenance, and feedback incorporation.
