General Stages of Software Development

Feasibility

• The assessment of whether a project or system is practical and achievable within given constraints, such as time, cost, technology, and resources.

Requirements

• The needs, capabilities, and constraints that a project or system must satisfy to achieve its objectives.

Analysis 

• Evaluating a project’s practicality and likelihood of success based on stakeholders’ requirements and expectations.

Design 

• Creating a detailed plan or solution that meets the project requirements and achieves the objectives.

• Including defining structure, components, and processes needed for implementation.

Design Aspects

• Inputs

• Outputs

• Security features

• Hardware compatibility

• User interface

Implementation

• Turning a conceptual software design into a working program by developing and coding said program.

Testing

• The process of checking a program to ensure it works as intended and meets the requirements.

• Involves finding and fixing errors or bugs before release.

Deployment

• The process of making a software available for its intended users.

Evaluation

• Assessing the software to determine if it achieves its objectives, fulfills requirements, and satisfies end-user needs.

Criteria of Evaluation to consider

• Robustness

• Reliability

• Portability

• Maintainability

Maintenance

• The process of modifying, updating, and improving software after deployment to fix bugs, enhance performance, or meet changing user needs.
