Study Notes
Software Life Cycle Phases
- Planning: The initial phase where activities before software development are defined. IT management determines requirements, financial plans, procurement, and sets the stage for future phases.
- Development: The core phase where software is created, focusing on design, coding, testing, and documentation.
- Testing: Validating the developed software to ensure it meets requirements, identify defects, and improve quality.
- Deployment: The process of installing the application into the production environment, making it accessible to users.
- Operation: The ongoing phase where the software is actively used and maintained, monitoring performance, addressing issues, and providing support.
- Maintenance: This phase focuses on keeping the software functioning properly and adapting to changes. It encompasses updates, bug fixes, and adding new features.
- Shutdown (Disposal): The final phase where the software is taken out of service. IT management decides when and if to shut down an application, based on factors like cost, obsolescence, and new software needs.
###Â Maintenance
- Maintenance includes upkeep and evolution of software systems.
- Upkeep: Addresses detected errors, optimizes runtime behavior, and improves resource efficiency.
- Evolution: Involves adding new features, adapting existing ones, and responding to user change requests.
- The effort for maintenance throughout a software's lifecycle often surpasses the initial development effort by a considerable margin.
Reasons for Software Replacement (Legacy Systems)
- Aging IT systems have a limited lifespan, requiring replacement to avoid high maintenance costs.
- Maintenance costs can become disproportional to the value of an outdated system.
- A lack of knowledge about older systems, due to technology obsolescence or staff turnover, can make maintenance difficult.
- New system functionalities or improvements in technology can necessitate a system upgrade.
Transition to a New System
- All technical interfaces of existing systems must be converted to the new system.
- For web applications, the new system must be accessible via the correct URL.
- The new system needs to be integrated with technical monitoring systems for security and resource usage tracking.
- IT security must include the new application in the list of monitored applications.
Planning Phase Considerations
- Determination of needs drives the decision to introduce a new software system.
- Need arises from factors like replacing legacy systems, accommodating business growth, or adapting to technological advances.
- IT management plays a crucial role in defining the project scope, requirements, and budget.
