Effective Software Development Life Cycle Methodologies

Software Development Life Cycle Methodologies

Jumping into a software development project without a plan is a recipe for over-budgeting and costly failure. That’s why companies rely on software development life cycle methodologies.

In the planning phase, developers gather input from customers, sales departments and market analysts to define the product requirements. The team then creates multiple designs for the product architecture and selects the most viable one.

Requirements gathering

This phase involves gathering and documenting all the information needed to define a software system. This includes interviewing stakeholders and users to understand their needs and expectations. It also involves evaluating and prioritizing requirements.

Effective requirements gathering can reduce the likelihood of costly changes and rework later in the process. It can also help ensure that the software system meets user needs and expectations and addresses business objectives.

This phase can involve creating functional prototypes that mimic the final product’s appearance and functionality to a degree. It can also include non-functional prototypes that focus on validating requirements such as performance, security, scalability, and usability. This information is then documented as a software requirement specification (SRS) or use case document. This documentation provides a roadmap for the development phase.

Design

The design phase converts the requirements gathered from the previous step into software for the project. This can take many forms, from low-fidelity prototypes to a final software system specification (SRS) or product specification document. This is an important part of the process, since it ensures that the final software will meet business goals, be feasible to create, and address user needs.

Another popular model is the iterative approach, in which development teams implement and test a small set of software requirements and then enhance each version. It’s a good option for projects that require flexibility in their requirements and can handle frequent cycles. In contrast, the Waterfall model has a very rigid progression and is best for projects that have well-defined requirements. It is not a good choice for iterative software development, however, because of the risk of delays and cost overruns.

Development

After gathering requirements, technology professionals move into the design and development phase. If the system is replacing an existing one, they examine that software to identify any deficiencies and then proceed to define what the new software will do.

The developers convert the requirements into a software design plan using their preferred framework. This will include a timeline, team resources, and budget requirements.

A key part of the coding process is making sure the code is correct and follows all the required standards. This will help avoid issues during the testing stage, which can save time and money in the long run. The Lean model encourages project teams to look for opportunities to cut waste by skipping unimportant meetings and reducing documentation. This allows them to focus on creating a better product in less time.

Testing

Technology professionals start the building phase by converting code requirements into software design. They may take existing software into consideration or work from scratch. The goal is to create a clear definition of the software’s end-to-end specifications.

Programmers then convert the design into program code. They can choose between Spiral, Iterative and Waterfall methodologies. The Iterative model allows developers to identify additional requirements as they go. This suits larger projects but requires good management and oversight.

The Spiral method takes a hybrid approach by blending aspects of Agile and Waterfall methodologies. It’s also flexible and adaptable to the unique needs of each project. Finally, the Lean methodology is based on manufacturing production and leans heavily on collaboration between developers and stakeholders. This ensures that every aspect of the project is reviewed and approved by all parties.

Deployment

The software deployment phase involves making the finished product available for users. Thorough testing and quality assurance measures are typically carried out during this stage to ensure that the software solution will perform as intended and meet customer requirements.

Depending on the type of software, the deployment process may use different techniques such as big-bang or rolling releases. For example, the blue-green deployment method uses two identical production environments, where current code is running on the “blue” environment while a new version of the code is deployed to the “green” environment. Traffic is then switched between the two versions, and performance is monitored.

A well-executed software deployment phase minimizes risk and ensures a high-quality end-user experience. It also makes it easier to update the software with bug fixes or other enhancements in the future.

Different Types of Software Applications

4 Main Types of Software

Application software is designed to fulfill specific system purposes. It includes programs like word processors, spreadsheets, and graphics software.

Unlike application and system software, programming software isn’t designed for end-users. It takes high-level computer languages such as JAVA, Python, and C++ and converts them into sets of instructions that a computer can understand.

1. Application software

Application software performs specific functions for end-users on a device like computers or tablets. This category includes everything from word processing programs to music players to search engines. It’s also the type of software that enables businesses/organizations to manage their customers and staff through systems like customer relationship management (CRM).

Application programs can run on hardware platforms with various operating systems. They’re developed in high-level languages like Java and C++. Unlike system software, application software communicates with end-users through user interfaces.

Word processing software helps users input, edit, format and print text content. This type of application software can add a variety of art features to text like colors, fonts and styles. Other examples of application software include spreadsheet programs to make working with numerical data easier and database management systems. Many of these types of application software are bundled together in suites that include word processors, spreadsheets and more. This is a great way for businesses/organizations to get more bang for their buck and streamline processes.

2. Operating system

The operating system is the “master control” software that manages computer hardware and provides common services for application programs. It is the first program loaded when you turn on a computer, and it resides in memory at all times. It shields application programs from the computer hardware specifics that would make them difficult to run, and it performs tasks such as caching frequently used data in memory to reduce disk access, ensuring there is enough memory available for application processes and handling error messages generated by applications.

Other types of application software include productivity and creativity tools like word processors, spreadsheets and graphics and CAD programs; real-time online communication and collaboration software like Skype, Google Hangouts and Web conferencing; multimedia and music player software; and security, maintenance and optimization programs such as antivirus and antimalware. Most of this software is installed according to users’ requirements, while system software is largely pre-installed and handles basic systems functions.

3. Firmware

Software system software makes your hardware function smoothly and securely. Without it, your devices would be little more than a collection of circuits and silicone chips. System software is not end-user oriented like application software but it is the base of everything that your hardware and applications do for you.

Device drivers are one of the system software categories that manages computer input devices, such as keyboards and mice that are physically connected to your computer. They translate the operating system’s input/output instructions into a form that your hardware can understand.

Firmware is a set of basic machine instructions coded into a piece of hardware that enables it to function. It’s sometimes referred to as “software for hardware,” but it’s different from software in that it doesn’t usually have the ability to update itself. Some examples of firmware include the BIOS on a computer and the firmware on storage devices like hard-disk drives and USB sticks.

4. Utility software

Like the mechanics of a machine, these computer software programs work tirelessly to ensure that your system stays in top working condition. By performing various functions including disk clean-up, file compression and system security, utility software contributes greatly to the performance and lifespan of your computer system.

While many of these computer software programs come with your operating system, you can find more advanced versions that offer additional benefits. For example, file management programs help you to navigate through the various files stored on your computer by organising them into neatly organised folders. By using compression techniques, these software programs can also reduce the size of these files, freeing up more storage space.

Other examples of utility software include anti-virus protection programs, disk tools and data backup solutions. They are all part of the wider category of system software that helps to support your computer infrastructure, distinguishing it from application software which is aimed at directly performing tasks that benefit ordinary users.
