• Business analysts.
• Clients or stakeholders.
• Project managers.
• End-users (for user feedback).

Software Development Process Step 2 - Planning

Once the requirements are clear, the next step is to create a comprehensive project plan. This plan outlines the scope, timeline, and resource allocation for the development project. It serves as a roadmap to guide the team throughout the development process.

Example of Planning steps in Software Development:

In our CRM project, the planning phase involves setting milestones, allocating development resources, and estimating project costs. A Gantt chart is created to visualize the project timeline, making it easier to track progress.

Uses of Planning steps in Software Development:

• Creating a roadmap for the project.
• Defining project scope, timeline, and resources.
• Allocating responsibilities and setting milestones.

Significance of Planning steps in Software Development:

• Ensures project goals are met.
• Provides a clear timeline for stakeholders.
• Helps manage risks and resources efficiently.

Advantages of Planning steps in Software Development:

• Facilitates efficient resource allocation.
• Prevents scope creep and project delays.
• Helps in risk management.

Disadvantages of Planning steps in Software Development:

• Plans may need adjustment as the project progresses.
• Excessive planning can lead to project paralysis.
• Uncertainties can make it challenging to create precise plans.

People Involved in Planning steps in Software Development:

• Project managers.
• Development team leads.
• Business analysts.
• Stakeholders.

Software Development Process Step 3 - Design

In the design phase, the software's architecture and user interface are developed. This step defines how the software will work and how users will interact with it. Design includes creating wireframes, prototypes, and system architecture diagrams.

Example of Design steps in Software Development:

For the CRM project, the design phase focuses on creating wireframes for the user interface. It involves designing the layout, navigation, and functionality of the CRM system. The development team may also design the database schema that will store customer data.

Uses of Design steps in Software Development:

• Creating a blueprint for the software's architecture.
• Defining user interfaces and user experience.
• Outlining database structures and system components.

Significance of Design steps in Software Development:

• Guides development by providing a clear structure.
• Enhances user experience and usability.
• Reduces the likelihood of rework during development.

Advantages of Design steps in Software Development:

• Promotes efficient and organized development.
• Reduces the likelihood of errors and oversights.
• Improves user satisfaction through thoughtful design.

Disadvantages of Design steps in Software Development:

• May lead to extended project timelines.
• Client feedback may necessitate design changes.
• Can be resource-intensive.

People Involved in Design steps in Software Development:

• System architects.
• UI/UX designers.
• Database designers.
• Development team members.

Step 4: Development

Development is where the actual coding of the software takes place. Developers write the source code based on the design and requirements. This phase can be time-consuming and requires careful attention to detail.

Example of Development steps in Software Development:

In our CRM project, the development team uses programming languages like Python, Java, JavaScript, or the programming language according to project goal to write the code for the CRM system. They create the various features, such as adding new contacts, updating customer information, and generating reports.

Uses of Development steps in Software Development:

• Writing source code based on design and requirements.
• Building the functional core of the software.
• Implementing features and functionalities.

Significance of Development steps in Software Development:

• Transforms design and requirements into a working product.
• Requires in-depth technical expertise.
• Demands attention to detail.

Advantages of Development steps in Software Development:

• Creates the software's functional core.
• Allows for customization and feature implementation.
• Facilitates a tangible product for testing.

Disadvantages of Development steps in Software Development:

• Can be time-consuming.
• Debugging and issue resolution may extend timelines.
• May require significant development resources.

People Involved in Development steps in Software Development:

• Software developers.
• Programmers.
• Quality assurance testers.
• Project managers.

Step 5: Testing and Deployment

After the development phase, thorough testing is crucial to ensure the software functions as intended. Testing includes unit testing, integration testing, and user acceptance testing. Once the software passes all tests and is free of critical issues, it is ready for deployment.

Example of Testing and Deployment steps in Software Development:

The CRM system is subjected to rigorous testing, including testing different user scenarios, data validation, and performance testing. Any identified issues are addressed by the development team. Once the software is deemed stable and reliable, it is deployed to the client's servers or the cloud, making it accessible to users.

Uses of Testing and Deployment steps in Software Development:

• Ensuring the software functions as intended.
• Identifying and addressing defects and issues.
