Software Development: A Complete Process for Software Creation

Table of Contents

In 1959, when software development processes lacked a clear development algorithm, the first computer program was created. The creators had no idea that program coding would develop over time into an efficient software development lifecycle.

Nowadays, every software development project adheres to a set of guidelines that enable the release of high-quality software. This is particularly true for start-ups in their early stages, where the procedures could appear a little disorganized.

The professionals at allassignmenthelp will discuss the stages of the software development life cycle and the various management approaches currently in use in this blog article.

A Brief Introduction to Software Development Process and Its Inception

The product development lifecycle has significantly changed since the 1950s, it was the time when the first computer program was developed. A uniform artifact was required by marketers, project managers, and developers to record the what, when, and why of each process across the development timeframe. The idea of the software development life cycle was developed in this manner.

The software development lifecycle (SDLC) is a methodical procedure that takes a product’s concept from conception to execution and ultimately to market.

The stages of the software development lifecycle typically include:

Requirement analysis
Planning
Software design i.e. architectural design
Software development
Testing
Deployment

The phrase “systems development lifecycle” was first used in Global Business Information Technology by Geoffrey Elliott.

Since that time, the SDLC has undergone numerous revisions to accommodate the development of complex business systems that called for extensive data processing and analysis. The primary objective of the software development life cycle is to produce high-quality software development within the allocated time and financial constraints. In light of this, different management approaches, such as Waterfall or Agile, have different software development processes.

Are you planning to get into the world of software development and studying software engineering but coding is taking all your night’s sleep? Not to be worried!

Life Cycle of Software Development: Agile Vs Waterfall

The Waterfall framework, a traditional software development algorithm, first appeared in the previous century. The software development life cycle has undergone significant change throughout time. The biggest change occurred in the 1990s when the software development lifecycle switched from the Waterfall to the Agile methodology.

Here are some details about both of these:

Waterfall Model: Reach Out to Perfection

The Waterfall SDLC’s history began in the previous century. The software development process back then was a bit like Archimedes’ law: individuals were aware that an algorithm was at work, but they hardly ever acknowledged or applied it.

When Dr. Winston W. Royce published his book in 1979 and described the Waterfall technique, the situation changed quickly. The concept was described by the author as a natural development of the software life cycle, similar to the cascading steps down an incremental cascade.

Agile Methodology: Change and Adapt

When the Agile technique was introduced in the 1990s, a new era in the software development process was inaugurated. Agile methodology brought a user-centered perspective on software development, much like the Renaissance era did with its human-centered refrain. At present, the entire software development process is focused on meeting users’ expectations in a faster, better, and more flexible way.

The stages of the Waterfall paradigm are carried over into the Agile methodology. The primary distinction is that the entire timeline is divided into a number of sprints, where the steps cycle around and repeat one another.

Steps Involved in the Software Development Phase

The development of software was influenced by the Agile philosophy. However, the linear, logical process that was initially presented in the Waterfall is followed by both approaches to software development.

Both Waterfall and Agile software development follow these five steps:

Step 1 – Prepare Requirements Collection

Gathering all the product’s functional and non-functional requirements is a critical first step. Project managers do this by speaking with stakeholders, doing research, and developing a picture of possible consumers through exploratory work. A software specification document usually compiles the findings of such a study.

Step 2 – Think About UI/UX Design

The team commences the design phase by creating the product’s visual representation. The process phase of user interface design represents how users will view the application.

But there is much more to software design than just pretty pictures. User interface organization, user flow comfort, and all facets of user interaction are addressed by UX design. UX design aligns with the idea of Lean Design in the Agile process. It denotes that the app’s design is user-centered and geared at identifying and meeting the needs of the user.

Step 3 – Focus on Coding

The third phase is where the team actually begins to code the ideas mentioned previously. All models, business logic, and service connectors described in earlier stages are now put into practice by the development team.

Since it forms the basis of the entire process, the coding phase is typically the lengthiest. To create a product that meets stakeholder expectations, the development team adheres to the software requirements. The development stage shouldn’t be problematic if the preceding steps were completed thoroughly and the circumstances are clear.

Alpha, beta, and release candidate phases are followed by the product build stage in the development process. The testing phase begins once the full architecture (DB, API, etc.) and the intended functionality of the solution is constructed.

Step 4 – Review Your Product with QA Stage

The testing experts identify and communicate any issues they find during system use during the QA stage. Depending on the project, different testing frameworks, including automated and/or manual testing, may be used.

Step 5 – Care About Your Product with Operations Stage in Software Development Stage

The program is then finally launched in a real-world setting. To stay current and functional, the system needs to be deployed, supported, and maintained during this phase.

The software development cycle ends here in the Waterfall methodology, however, in Agile, the team would restart the cycle with a new iteration of the product.

Conclusion

The software development cycle is essential for producing high-quality products that satisfy customer needs. The fundamental elements of the development process are the same whether using traditional Waterfall or flexible Agile.

To conclude it can be said that, the way of developing software has changed a lot and the journey of developing these also have become way easier. Still, it needs a lot of patience and understanding regarding the entire procedure.
