Software Development Process Overview

Identifying the goals, requirements, and constraints of a software project.

Developing the actual software, including design, coding, and testing.

Maintaining and evolving the software after its release to fix errors, adapt to changes, or add new features.

Corrective maintenance changes the software to fix defects and bugs.

Adaptive maintenance modifies the software to adapt to changes in its environment, such as new platforms or regulations.

Perfective maintenance enhances the software, adding new features or improving its performance.

Preventive maintenance aims to prevent future problems by improving the software's design, documentation, or testing.

A set of guidelines and practices that define how a software product should be built, deployed, and managed.

A software development model that progresses through distinct phases in a linear, sequential manner, starting with feasibility studies and ending with maintenance.

The first phase in the Classical Waterfall Model that determines the technical and financial viability of developing a software project.

Focuses on understanding and documenting the user's needs and requirements for the software system.

The process of creating the blueprint for the software system, including its architecture, modules, and relationships.

The phase where the software is coded and individual components are tested.

The phase where individual code modules are integrated into a functional system and tested together.

The ongoing process of fixing bugs, enhancing features, and adapting the software to changing requirements.

This phase focuses on the quality of the product, determining how the software will be built. There are two main approaches: traditional and object-oriented.

This approach divides the software design process into two parts: analyzing the problem's structure and then designing the software's structure.

This part of the traditional design approach involves examining the detailed structure of the problem, identifying processes, and understanding the data flow between them.

A diagram used in structural analysis to visualize data flow and processes in a system.

During this phase, the results from structural analysis are used to create the actual software design.

This level of design focuses on breaking down the system into modules and defining the relationships between them.

This level of design focuses on the details of individual modules, including their data structures and algorithms.

This approach emphasizes identifying objects and their relationships within the software system. It often leads to faster development.

A software development model where the software is built in stages with incremental delivery of functional versions.

The first version of the software in the incremental model, containing the basic core functionalities.

The process of adding new features and functionalities to existing software versions, enhancing its capabilities over time.

The delivery of a functional version of the software to users for evaluation and feedback, even if it lacks all desired features.

Using the iterative waterfall model techniques to develop each version of the software in the incremental model.

The advantage of the incremental model where each new software version delivers more useful work than the previous one.

The advantage of the incremental model where the initial product is delivered faster, allowing for earlier user feedback.

The advantage of the incremental model where core modules are thoroughly tested, reducing the risk of major errors in the final product.

A software development model that emphasizes rapid development cycles, often using pre-built components to create a functional system quickly.

A software development model that builds complete functional units of a system simultaneously by dividing the project into multiple teams.

A special version of a software application that is released to a limited group of users for testing and feedback.

A software development model that focuses on building a working prototype of the system to get early user feedback and refine requirements before full development.

A disadvantage of the Prototype Model, where the code built for the prototype is often discarded and not reused in the final product.

A drawback of the Prototype Model, where the initial cost of building the prototype can be significant.

A challenge of the Prototype Model, where user dissatisfaction with the initial prototype could dampen their enthusiasm for the final product.

A requirement of the Prototype Model, involving end users in the development process to provide feedback and refine the system.

A software development model proposed by Boehm in 1986, which utilizes iterative cycles with increasing complexity and detail, resembling a spiral shape.

The use of fourth-generation languages (4GLs) and development tools in the Spiral Model, allowing for faster and more efficient development.

A visual representation of the Spiral Model that resembles a spiral with multiple looping cycles, symbolizing the iterative development process.
