Understanding the Software Development Process

Understanding the software development process is key to executing software projects successfully. Formally addressed in software engineering as software development life cycle (SDLC), it acts as the backbone for building software applications. It is a software development value chain with well-structured phases, where each phase contributes to the final product.

Yes, the process matters because it lays down a clear roadmap, and helps the team avoid pitfalls and stay on track. Without it, software projects can quickly go off the rails, and lead to delays and cost overruns.

Starting with the phases of software development, we’ll walk through each step, highlighting its importance and role in building high quality software efficiently. Afterward, we look at the best practices you can adapt in your software development process. Let’s jump right into the nuts and bolts of the software development process.

Software Development Process

Software Development Process is a procedural way to build and maintain a software product. The whole software development process includes planning, information gathering, feasibility check, system analysis, design, code, test, integration, deployment and maintenance.

Planning

Start by setting a clear roadmap, to allocate resources effectively and allow your team to anticipate challenges. Build a plan to best manage expectations and ensure that the final software product delivers tangible business value. In planning process, you will

1. Define project scope to establish boundaries and deliverables.
2. Set project objectives aligned with strategic goals.
3. Identify and allocate necessary resources, including personnel and budget.
4. Develop a detailed project plan with timelines and task assignments.
5. Create a risk management strategy to identify and mitigate potential issues.
6. Establish a communication plan to keep everyone informed and engaged.
7. Define milestones and deliverables by establishing KPIs to track progress.

Requirement Gathering

Requirement analysis is dedicated to understanding and documenting the needs of users. You need to employ various techniques such as interviews, surveys, and workshops to collect both functional and non-functional requirements and derive a comprehensive requirement specification document that will serve as a blueprint for the entire project. By thoroughly validating these requirements, this phase reduces the risk of misunderstandings and scope creep during later stages of development. For that

1. Conduct interviews to gather detailed insights into user needs.
2. Facilitate requirement workshops for collaborative requirement definition.
3. Distribute surveys and questionnaires to capture a wide range of inputs.
4. Create use cases and user stories to detail specific functionalities and user interactions.
5. Document functional requirements to specify desired system behaviors.
6. Capture non-functional requirements such as performance, security, and usability.
7. Review and validate requirements with clients to ensure alignment and completeness.

Feasibility Study

Evaluating the practicality of the proposed project across technical, economic, and operational dimensions is one key step that must not be missed. Analyze whether the technology stack is suitable, the project is economically viable, and the organization can operationally support it. Based on these findings, generate a feasibility report providing a detailed assessment of risks, benefits, and potential constraints, and aid decision-makers in determining whether to proceed. Carry out these steps for successfully feasibility analysis:

1. Analyze technical feasibility to determine if the proposed technology is suitable.
2. Conduct a cost-benefit analysis to evaluate financial viability and benefits.
3. Evaluate operational feasibility to assess the organization’s capability to support the project.
4. Identify potential risks and constraints that could impact project success.
5. Prepare and share amongst shareholders a detailed feasibility report with findings and recommendations.
6. Review the feasibility report before making any decision.
7. Make go/no-go decisions based on feasibility findings and inputs.

System Analysis

Here, you break down the system requirements to create detailed specifications and models. These models are validated to check if they accurately reflect requirements. System analysis plays its part by providing a clear and detailed blueprint, and allowing a smooth transition to the design phase and helps the team fully understand what needs to be built. For system analysis, you will need to

1. Create data flow diagrams (DFDs) to visualize data movement within the system.
2. Develop entity-relationship diagrams (ERDs) to represent data structures and relationships.
3. Perform system modeling and simulation to explore and validate system behavior.
4. Write detailed system specifications to provide a precise description of the system.
5. Validate models and specifications for accuracy and completeness.
6. Review requirements to identify and address any gaps or inconsistencies.
