Five Phases Of The System Development Life Cycle

Five Phases Of The System Development Life Cycle – Creating applications and solutions has become an integral part of business activity. Every industry, from healthcare to gaming, requires a development team to build, manage and test your business’s digital infrastructure. For this reason, it is important to understand the ins and outs of the application development life cycle (ADLC), also known as the software development life cycle (SDLC). To help you understand this concept, we’ll explain what the app development lifecycle is, explain the six phases you need to prepare for, and go over the different development models you can use.

The application development life cycle (ADLC) is the process of creating applications that incorporate user requirements while calculating the risks involved in advance. It includes all phases of the application development process, from requirements gathering to deployment, testing, and maintenance.

The application development lifecycle (ADLC) plays a critical role in how your application provides value to your customers. Following a well-defined structure for building, testing, and launching an application builds trust in the team and helps achieve a successful project outcome. Enforcing ADLC is not just a product manager’s job; It is important that each member of the application team understands and follows the life cycle with discipline.

Organizations typically follow a process to deliver requests on time. You must separate this process into the following phases.

The discovery phase is the most important phase of the life cycle as it establishes the requirements for what to build. During this requirements gathering phase, you collect user feedback, find deficiencies in the application, and establish an action plan to address them. Product managers usually do most of the heavy lifting during this part because this is where they gather important information about the application from stakeholders.

The design phase involves writing up solutions to problems encountered during the discovery phase. UX/UI designers are the most active participants during this phase as they work with the team to create possible solutions from a design point of view. UX/UI designers will use media such as blueprints, wireframes, and mockups to showcase these solutions and alert the team in advance of potential blockers.

At this point, the team should know what they need to do to improve the user experience. During the development phase, the real fun begins. Software developers are the most active participants during this time because they are in charge of making product requirements a reality. It is important to note that sometimes the development team can be divided based on the architecture of the application (monolith vs. microservices).

Once the development team creates the necessary features, the application is ready to be tested. At this point, the team configures one or more environments to reflect the production version of the application so that they can test its functionality (either manually or through automated integration testing pipelines).

Quality control professionals and security engineers participate in this phase, with the sole objective of finding problems that prevent the application from working as it should. Issues found during this phase, such as bugs, security and compliance issues, are reported to the development team so they can fix them. Due to limited time, the team will likely prioritize issues in order of severity and decide whether to fix some or all of them.

The QA team is often the last line of defense because they decide whether certain features are ready for users.

Once the QA team examines the app for accuracy, the app is ready for the customer to use. This step usually involves increasing the version of the app to reflect the latest version and sending updates to users indicating that newer versions of the app are available for download.

You’re not done yet though! After you deliver your application to the customer, it is still essential to update and maintain it to fix bugs, security vulnerabilities, compatibility fixes, and other issues that may arise.

Although most organizations opt for the agile or waterfall approach, you can use many different models (or methodologies) to bring your application to life. Let’s review some examples of the following.

The waterfall model is the most traditional and simplest approach to building an application. The model is named so because it shows the phases as a waterfall. With this model, you must follow each step sequentially and not overlap. The waterfall model is a great option if the requirements are constant and do not change periodically.

The agile model is one of the most popular and used approaches to building applications. The agile methodology states that the value of a product must be delivered in stages. Compared to the waterfall model, where each step is followed one by one without any overlap, the agile model encourages and expects overlapping phases.

The V-shaped model considers testing during each phase of application development. It is very similar to the waterfall method, but includes the corresponding testing stages as additional visual elements.

In an iterative model, the development team typically starts with vague requirements to create the initial version of the application and then improves it after each release.

The spiral model incorporates risk when delivering your application to customers and involves a series of steps that quantify risk analysis, prototyping, experimentation, and evaluation.

Unlike the models mentioned above, the DevOps model is relatively new to the industry. It emphasizes that software delivery is a joint effort between the Development (Dev) and IT Operations (Ops) teams, and its ultimate goal is to improve the speed and quality of the final product.

Although we have provided a detailed overview of what the application development life cycle (ADLC) entails, there are many other resources you can review to better understand the topics related to application development. We recommend exploring the following hubs and blog posts to learn more about how you can help your team. Customer needs are changing at a rapid pace, particularly in software development. Agile development encompasses constant change through an iterative technology design and development approach.

In a world where adaptability is essential, Agile offers a framework that enables rapid changes and customer-centric solutions. According to a comprehensive study on agile software development, this approach is efficient in today’s fast-paced technology landscape.

The agile lifecycle adds structure to a fluid and flexible method of delivering a functional product. Breaking builds into smaller segments delivers a better product faster.

This approach is not just about speed: it is about delivering quality and value at every stage, ensuring that the final product aligns with user needs and market demands.

Five Phases Of The System Development Life Cycle

The agile lifecycle is a dynamic, flexible approach to software development designed to deliver high-quality products that meet customer needs. This cycle is divided into five critical stages, each with its unique focus and set of activities. They are:

The first stage in the agile software development lifecycle is often called the startup or vision phase. During this stage, an agile project charter is prepared during project initiation to discuss the project vision and ROI justification. Here, it is essential to consider the role of DevOps to align with the project vision for a smooth development and deployment process.

This is a high-level feasibility discussion and does not delve into specific details. During this step, you must identify the team members and determine the work time and resources required to complete the project. Taking stock of resources is crucial to decide the economic viability of project approval.

This speculative phase is when the agile lifecycle takes shape for the team. Release planning is where the team meets with their sponsor or product owner and identifies precisely what they are looking for.

They discuss how this will be possible by building the backlog at the story level. You can read about agile sprint planning for a more detailed guide on this.

Value stream management can also be incorporated into planning to make data-driven decisions and prioritize. Below are the key components that are integral to the agile planning phase:

Planning is only complete when the backlog is completed and items have been prioritized based on value and business dependency. The importance of planning in agile methodologies is further emphasized in a review of Agile Methodologies applied to the development of Internet of Things (IoT) based systems.

The development stage begins once the planning phase is complete and the requirements are clearly defined. Agile development thrives on delivering high-quality, functional products through incremental steps known as sprints or iterations.
