What Are the 7 Phases of SDLC (Answered)

The software development life cycle is a process used to create, maintain, and modify software applications. Also, it helps you to develop the best strategies for achieving your primary business goals. But, what are the 7 phases of SDLC?

An Overview of the SDLC Process

The process starts with planning and ends with the maintenance phase. This includes tasks such as requirements analysis and design.

Other parts include coding, testing, and deployment as well as specialized services such as back end development services. Generally, SDLC models assist firms to meet their deadlines and manage their budgets.

It also allows decision-makers to predict if their software continues to be a worthwhile effort.

Therefore, many compare SDLC to the Agile or Waterfall approaches. As a result, a great number of enterprises utilize a hybrid approach.

To finish a development process for a software project you’ll need all of the divergent phases of SDLC. Hence, apply all of the seven SDLC phases in succession.

However, you can insert small alterations depending on the chosen model.

First Phase: Preparation and Analysis Stage

Preparation is the most essential step in the system development process. The organization’s software developers perform the analysis needed to finish this phase of SDLC.

The preparation stage comprises strategic objectives, such as:

  • Assets assignment
  • Scope planning
  • Project scheme
  • Value projections
  • The required equipment

The requirements analysis assesses the features and capabilities of the software. Also, it inspects its users and usability methods.

So, it considers the target audience and the business objectives that the software aims for. Additionally, the analysis typically includes a review of the existing system.

In short, the planning stage includes design projections, fee forecasts, and provisioning.

Project managers and development personnel collude with all project teams when making decisions. Working together, they can ensure all security solutions go live in an effective manner.

Second Phase: Provision Characterization

The first stage should result in a detailed validation of the final product. Then, consumer analysts approve the product’s requirements. For that, they use the Software Requirement Specification document.

The SRS document lists the requirements of the software, hardware, and other necessary components. To that end, it covers all of the system development life cycle phases.

Programmer personnel can:

  • Interpret any example system prerequisite
  • Coke up with substitutes for the existing exemplars
  • Identify customer needs and preferences

Third Phase: Creation of Architecture

This stage houses the process of defining a structured solution. This solution has to meet all the technical and operational requirements. Hence, this architecture is the foundation of any software system.

The software architects utilize advanced techniques at this stage. For example, analysis of the current system, use-case diagrams, and database diagrams.

You can divide the third stage process into several components:

  • User interface: Analysis of how consumers interconnect with the software. Also, analysis of how well the software counters certain inputs
  • Coding: Consideration of all the aspects concerning programming language and all possible customizations
  • Architecture: Consists of business customs, templates, total design, and programming languages
  • Platforms: Configures the platform on which the software system will be built on
  • Connections: An overview of the techniques for interacting with third parties
  • Safety: Detailing the treads made for system security. This process can contain SSL traffic encryption, password protection, and user credentials protection

The next step is creating a prototype version of the software system. The prototype should include the basic features of the app. Also, it should comprise some mock data and interactions.

Prototyping is an important step in the software development process. It allows developers to test the design and functionality of the app. Then, you can resume the final steps.

Additionally, it can also provide potential users with a better notion of the app’s features. This helps reduce the risk when the final product goes live.

Finally, all stakeholders can inspect and review the application. They can provide feedback on how well it meets the desired requirements. Also, they can suggest any changes for boosting its efficacy. Next, the development teams review those points. Once the changes are complete, the application is ready for final testing and launch

Fifth Phase: Software Testing Stage

Testing is the process of evaluating a system or its components. As such, it aims to uncover whether it satisfies the specified requirements. In software engineering, testing is an important component of quality assurance. This represents the ultimate review of specification, design, and coding.

Testing the entire system helps to identify errors. At the same time, it detects gaps or missing links that bog down the product. Plus, it helps to ensure that a system meets its end-user requirements and achieves its goal.

Sixth Phase: Distribution

After the software development is complete, the test and QA process begins. For that, engineers must possess excellent problem-solving and communication skills. More often than not, they’ll need to provide technical support and troubleshoot issues.

Other than that, they’ll need to answer questions about the developed system. They should also help train customers on how to use and optimize the app. Additionally, they need to ensure the software remains up-to-date. Another task will be managing user accounts and performing other administrative tasks.

Thus, this stage involves moving the product from development into a production environment. Hence, you need to verify that the product is working correctly at this point.

Furthermore, the IT team must understand how the APIs in place support the product. On that note, they should know how to monitor and support the APIs. Lastly, IT employees need to be certain that all changes serve to improve the app’s quality.

Seventh Phase: Software Processes and Upkeep

The operation and maintenance phase is the last one in the software development life cycle.

This development life cycle (SDLC) includes regular upkeep. Commonly, the maintenance includes bug fixes, security updates, and other improvements.

Depending on the type of software, users may also need to perform regular backups and optimization.

The goal is to ensure that the system works as expected and meets the user’s requirements. This phase also involves updating the system to make sure it keeps up with an evolving market. This includes making changes to the software code and ensuring that the system is secure and reliable.

Iterative development models are a great way to build products in a way that allows for efficient, continuous improvement.

These models focus on the idea of breaking down a project into several chunks. Hence, iteratively adding new features and improvements over time is one of the model’s goals.

It allows for the product to be developed in a way that it can quickly adapt to customer feedback and other market conditions.
