1. Make a plan
Project leaders review the project’s terms during the planning phase. Calculating labour and material expenses, developing a schedule with specific deadlines, and forming the project’s teams and leadership structure are all part of this process.
Stakeholder feedback can be integrated into the planning process. Anyone who stands to benefit from the application is referred to as a stakeholder. Obtain feedback from prospective consumers, developers, subject matter experts, and sales representatives.
The scope and objective of the application should be clearly defined during planning. It charts a course and equips the team to produce software efficiently. It also establishes limits to prevent the project from expanding or diverging from its initial goal.
2. Define Requirements
Defining requirements is part of the planning process to figure out what the application is supposed to perform and what it needs. A social media program, for example, would necessitate the ability to connect with a buddy. A search feature may be required by an inventory program.
The resources required to complete the project are also defined in the requirements. A group might, for example, create software to control custom manufacturing equipment. The machine is required for the process to work.
3. Prototyping and Design
The Design phase simulates the behavior of a software program. The following are some of the design elements:
- Programming language, industry norms, overall design, and use of any templates or boilerplate are all examples of architecture.
- User Interface (UI) – Defines how customers interact with software and how it responds to input.
- Platforms – These are the operating systems that the software will run on, such as Apple, Android, Windows, Linux, and even game consoles.
- Programming – This term encompasses not only the programming language, but also the methods for solving problems and carrying out duties in the application.
- Communications — Defines how the app can communicate with other assets, such as a central server or other instances of the app.
- Security — Defines the steps used to keep the app safe, such as SSL traffic encryption, password protection, and secure user credential storage.
Prototyping is a step in the design process. In the Iterative software development approach, a prototype is similar to one of the early versions of software. It gives you a general idea of how the app looks and functions. Stakeholders will be able to see this “hands-on” design. Use feedback to help you improve your app. It is less expensive to make changes in the Prototype phase than it is to rewrite code in the Development phase.
4. Development of software
This is where the software is really written. A small project may be created by a single developer, whereas a large project may be divided into numerous teams. During this phase, use an Access Control or Source Code Management solution. Developers can use these tools to keep track of code modifications. They also assist in ensuring that different team initiatives are compatible and that target goal are met.
Many other jobs are included in the coding process. Many developers need to brush up on their abilities or collaborate with others. It’s vital to find and resolve problems and flaws. Waiting for test results or generating code so an application may run are common tasks that slow down the development process. SDLC can foresee these delays, allowing developers to be reassigned to other tasks.
Instructions and explanations are appreciated by software developers. Documentation can be a structured process that includes wiring an application user guide. It can also be more casual, such as comments in source code explaining why a developer adopted a particular approach. Even organizations that seek to build simple and intuitive products might benefit from the documentation.
Documentation can be a quick walkthrough of the app’s basic functionality that appears when it initially starts up. It may be video tutorials for more difficult tasks. User guides, troubleshooting guides, and FAQs are examples of written documentation that can assist users in solving problems or answering technical inquiries.
Before making an application available to users, it’s vital to test it. Much of the testing, such as security testing, can be automated. Another testing can only be done in a specific context; for complex deployments, consider developing a simulated production environment. Each function should be tested to ensure that it functions properly. Different elements of the application should also be evaluated to ensure that they function together seamlessly—performance testing, to eliminate any processing hangs or lags. The testing process assists in reducing the number of faults and glitches seen by consumers. As a result, there is a higher level of user satisfaction and a higher rate of utilization.
The application is made available to users during the deployment phase. Many businesses prefer to have the deployment step automated. This might be as straightforward as a payment portal and download link on the company’s website. It could also be the installation of an app on a smartphone.
Deployment can be difficult as well. One example is migrating a company-wide database to a freshly designed application. Because the database relies on numerous other systems, integrating the upgrade may take extra time and effort.
Maintenance and Operations
The development cycle is practically complete at this stage. The application has been completed and is currently being utilized in the field. However, the period of operation and maintenance is still crucial. Users find flaws that were missed during testing during this phase. These issues must be addressed, which may result in new development cycles.
Models like Iterative development propose extra features in future releases in addition to issue patches. A new Development Cycle can be started for each new release.
