Software product development phases

Brief of S/w project phases

In briefest explanation involves 4 phases. see diagram

  1. Inititation
  2. Planning
  3. Execution
  4. Closure


Software product development typically involves several phases, including:

  1. Planning: This phase involves identifying the problem or opportunity that the software will address, gathering requirements, and creating a project plan.

  2. Analysis: During this phase, the requirements are analyzed in more detail and a high-level design of the software is created.

  3. Design: In this phase, a more detailed design of the software is created, including the architecture, user interface, and specific features.

  4. Implementation: This phase involves writing code and building the software according to the design. Codes should be standardized as much as possible. It should be well documented for future reference. eg doxygen

  5. Testing: The software is tested to ensure that it meets the requirements and functions correctly.

  6. Deployment: The software is deployed and made available to users.

  7. Maintenance: After deployment, the software is maintained and updated to fix bugs, add new features, and address any issues that arise.

Design Phase

The design phase of software development is when the software's architecture, user interface, and specific features are defined in more detail. The goal of this phase is to create a detailed plan for how the software will be built and how it will function.

During the design phase, the following tasks are typically performed:

  1. Architecture Design: The high-level design created during the analysis phase is refined to create a detailed architecture that defines how the software will be structured and how different components will interact.

  2. User Interface Design: The user interface (UI) is designed and created, which includes the layout of the screens, the buttons, and the overall look and feel of the software.

  3. Feature Design: The specific features that the software will include are defined and designed in more detail. This includes the functionality that the software will provide and the details of how it will work.

  4. Data Model Design: The data model, which defines the data structures and relationships used by the software, is designed and created.

  5. Algorithm Design: The algorithms that the software will use to perform specific tasks are defined and designed.

  6. Pseudocode or flowchart: A high-level representation of the software's logic and flow is created in the form of pseudocode or flowcharts.

The design phase is an iterative process, meaning that the design may be refined multiple times before it is finalized. This is often done through design reviews, where the design is reviewed and evaluated by a team of developers, designers, and stakeholders to ensure that it meets the requirements and is technically feasible.
