Study Notes
SDLC - Software Development Life Cycle
- SDLC is a structured approach to developing software, encompassing various phases from initial concept to deployment and maintenance. It helps manage complexity, risks, and resources efficiently throughout the entire process.
1. Defining
- This initial phase focuses on understanding the project's goals and objectives.
- It involves identifying the problem the software is intended to solve and defining the desired outcome.
- Key activities include stakeholder analysis, gathering requirements, and defining scope.
- Example: Understanding the need to automate employee timesheet submission, outlining desired features (e.g., online submission, integration with payroll system), and identifying key stakeholders (employees, managers, HR).
2. Planning
- This phase involves creating a detailed project plan, outlining tasks, timelines, resources, and budget allocation.
- Risk assessment and mitigation strategies are crucial elements of this step.
- Example: A project plan defining specific tasks, responsibilities for each team member, timelines for completing each phase (e.g., design, development, testing), estimates for resources and budget, and potential risks like technical issues or delays.
3. Feasibility
- This critical step assesses the practicality and viability of the project.
- It evaluates technical, economic, and operational aspects of the project.
- Analysts study the project to determine whether is realistically possible to develop and manage the proposed project in the planned time schedule and budget and resources.
- Example: Evaluating the technical feasibility of integrating a new software system with existing infrastructure, analyzing the economic justification of the project, and assessing the organizational capacity to manage the implementation.
4. Requirement Engineering
- This phase meticulously defines user needs and system requirements.
- It ensures a clear understanding of what the software should do and how it should perform.
- Gathering data from users to understand their expectations of the software.
- Example: Creating user stories, use cases, and detailed documentation outlining specific functionalities, user interactions, and data requirements for the software, collecting information through surveys, interviews, and workshops with stakeholders.
5. Design
- This phase focuses on creating a blueprint for the software system.
- It involves defining system architecture, database design, and user interface (UI) design.
- It's the process of deciding how the software will be implemented including specific components, data structures, and interface designs.
- Example: Designing the overall architecture of the software, including diagrams, layouts, and system modules. Also, database schema design and user interface mockups are developed. This phase also specifies the specific technology stack to be used (e.g., programming languages, frameworks, databases).
