The Software Development Life Cycle (SDLC) is what?
The SDLC is a summary of the steps involved in creating software, to put it simply. You could even refer to it as a progression of stages that software goes through as it develops.
Be aware that any software development, whether it is part of planning or not, follows the same process from planning to launch. The phases of the overall plan are generally referred to as the “Software Development Life cycle” (SDLC).
Another way to express it is that each step creates an output that is subsequently used as an input for the step that follows.
You can relate it to baking a cake when put into casual terms. The first step over here is to mix the flour with the vanilla bean powder, followed by the butter and eggs to make a baking mixture. However, if you don’t follow the correct technique here, your baking will turn out poorly.
Planning for software development is no different. Please take note that the process does not change regardless of the software development methodology you use.
Must Understand the Value of the Software Development Life Cycle.
Though many of us continue to ponder the question, “Why are steps in the software development process important?” Your software will benefit greatly from using a faultless SDLC.
The same answer may be found for the points listed below! Let’s delve right in!
Increase the specific roles and duties assigned to each team member. (Project managers, QA, designers, and software developers, for example)
Enables the entire team to remain on the same page, so preventing any disruption and confusion during the process.
Facilitates open communication between clients & software engineers.
The SDLC enforces the ideal step of “definition of done” to ensure that the project moves forward without any creep. This guarantees that a stage of the development process is finished and prepared to go on to the following stage.
Two advantages of using a software development strategy are quality and on-time delivery.
Regardless of the size of the project, the software development process makes it easier to handle everything. Visualize the complete development process, in other words.
The SDLC method ensures the development of high-quality software. because there is no room for bugs given the synchronous procedures taken.
The Process of Developing Software in 7 Stages
1. Planning and Analysis
Gathering requirements from clients or other project stakeholders is the first phase in the SDLC process. The demands and issues of the client’s project are identified, and these serve as the foundation for determining the requirements.
The gathered provisions are next subjected to a brief study. The best software solutions are developed after conducting market research and competitor analysis.
In addition, the four main aspects of software development to consider are;
Alignment: The kind of software you require to dominate the market and generate the anticipated ROI.
Resource management: Establishing teams to distribute the project phases. For instance, a software project needs four software engineers, two quality assurance specialists, two designers, a project manager, and so forth.
Cost estimation: Researching the typical price of software development is important. Discussion with the software development business is essential.
Check the estimated delivery time to learn how long it takes to develop software.
The first stage of the software development process is when a Proof of Concept is developed.
To sum up, at the end of this phase, you must have a complete understanding of software development and have the data necessary to create a scope of work.
You worked on everything in the first SDLC stage to create a scope of work. It’s time to focus on the technical needs for software development.
In this section of software development planning, you need to receive an answer to a few queries, including;
- What kind of remedy does your software offer?
- What kind of data input and output are required?
- Security of data and software requires planning
- API types that must be integrated
- Tech stack to use when developing software
- Which users are being targeted?
- Number of additional features
There are many more, but these are some of the most important ones that you and your team should ask.
You and your development team must also choose the models of software development processes that will be used for your project. (All of the models are detailed in the article’s later section.)
It’s time to execute the plan after everything is clear.
Come on, Team! Say it aloud!
3. Creation of prototypes
Keep in mind that design is fundamental to the success of software. Let’s get to work on your project’s software architecture. This architecture secures your software development process from beginning to end.
Design Hint: Creating software involves much more than just aesthetics; it also involves overall functionality and user experience.
We’ll start by making a simple prototype of your app. Through design components, this verifies the appearance, feel, and functionality of your software. In other words, it will provide you a preview of what the software deployment will look like. These prototypes are produced with the aid of design software, like Figma, Marvel, InVision, Sketch, and many others.
Software architecture follows after that. The team creates an orderly flow of the components in the software code at this point for quality control, usability, and clarity. Some of us even refer to software architecture as a blueprint for the fundamentals of software development. as a detailed blueprint for how software’s functional modules will operate at the code level.
When the design is finished, you can share it with your team and devoted users to gain insightful comments and make necessary modifications.
You are now ready to write the code for your software idea.
4. Development of software
It’s time to enlist everyone!
Here we move to develop the finished product based on the SOW and requirements with all the suggested designs and functionalities.
Using the predetermined tech stack, the software engineers write and implement KLOCs (thousands of lines of code) to create a profitable solution.
Additionally, here you may perform software development tasks including setting up environments for automation of development and delivery, developing server-side API codes, and much more.
Another thing to do is to create a completely functional GUI from the static user interface mockups. Software developers carry out analysis with respect to unit testing and static code.
Here, the objective is to adhere to the SOW in order to create quality software. As a result, we might even refer to this SDLC level as the most significant and potent.
Note: Depending on the needs communicated by project stakeholders, software development is carried out in a variety of ways.
Recognize that testing is an ongoing part of software development. Parallel to development, it happens.
The two main types of testing are manual testing and automated testing.
To put it briefly, the testing, bug-tracking, and bug-fixing processes are integral to the software development process. Additionally, thorough testing is done after all the features have been completed and the product is ready to use.
The testing part of the SDLC is a lengthy procedure, just as the development phase. However, you must take care to avoid providing your real-time consumers with a flawed piece of software. This can leave a lasting impression.
In this stage of software development, risk assessment is done along with testing. Prior to release to the market, the software testers will do a thorough risk analysis of your software.
In conclusion, testing professionals and software engineers work together to ensure that your system development life cycle is bug-free.
Now that your program has undergone planning, designing, development, and testing, it is prepared for use.
The software has all of its issues fixed, and it is now ready for deployment. The production environment phase involves all or a portion of the software. Depending on the models of the software development process used, software deployment varies.
If end users encounter any defects after deployment, the product is returned to the development team.

7. Upkeep and updates
Change is a fact of life, as is often remarked. The software is no different in this regard. New features, technology, and many other things enter the market as time goes on.
To remain competitive, your software must be updated and maintained as necessary. To account for the new software requirements, the software development teams reevaluate the entire software development life cycle.
The two prevalent forms of maintenance include;
Perfective Maintenance: The complete software concept is being reexamined in light of the newest trends and technology in the industry. The software is consequently upgraded to reflect the modifications.
Corrective maintenance: In this process, performance is improved by removing defects from the installed software. The users typically spot the problems and then delete them.
The process of developing software has now come to an end. However, there is still a crucial section of the text to cover: software development approaches.
Without further ado, let’s head in that direction!
Software Development Methodologies: Types
For handling simple to complex projects, a variety of software development process models have entered the market. Here, we’ve listed the top 5 categories of business software development processes.
Depending on the size of your project, your team, and your desired outcomes, you can select any of them. To give you a better sense, we have created images for each model.
also referred to as the traditional lifespan model or the linear sequential model. You should be aware that one of the oldest methods for developing software is waterfall.
The only guideline in this situation is to finish the previous step before going on to the next. And for this reason, some even refer to it as a “plan-drive” model. The order and development deliverables must be known before the project can begin.
Imagine a staircase for the finest illustration in this scenario. While descending, each step must be crossed. The waterfall process is the same.
The Waterfall Model’s phases are;
- Software system design
- Product Release
Scrum and Agile Model
The agile approach and its scrum methodology use a distinctive, iterative, and dynamic approach to development, directly opposing the waterfall technique.
For the purpose of developing and releasing the usable software model to the consumers for their feedback, the cross-functional team works in “Sprints” for 3 weeks to 3 months.
As a result, Agile is a dynamic and quick methodology that relies on customer feedback. It is frequently made public to gauge user reaction. If it conflicts with user feedback, the original strategy actually alters. Examples of this software development process include Scrum, Crystal, Agile Modeling (AM), and Extreme Programming (XP).
Agile is thought to be the most appropriate approach for software development, according to a GoodFirms poll. This methodology aids in the creation of about 61% of projects.
There, a list of requirements and a SOW are not necessary before beginning the designing phase of the agile and scrum software development processes. The steps in this SDLC process are as follows:
- Inventory backlog
- Agile backlog
- Sprint (Design & Develop) (Design & Develop)
- Publish functional software
- feedback and approval (add to backlog)
- Organize the subsequent sprint
Iterative and Incremental Model
This is what is known as a waterfall and agile software development hybrid. Here, the waterfall model’s gradual and iterative processes represent its middle ground, but agile’s flexibility is present.
Let’s examine each phase of this model independently.
Here, the idea is to construct small software components and then get user input. The software component that you develop for every release is one area where it varies. You could even use it as a scale model of a waterfall.
Each iteration adds a new feature or functionality to the software’s finished product. The component is tested and validated before being moved to the next increment.
The steps in an incremental process are as follows:
- Increment Planning
- Repeat for each version
This software development paradigm contains all features and functionalities in the form of versions throughout the full software development process. Say it’s version V1.1. Remember that version 1 has the fewest features and functionalities.
Version V1.1 is subsequently upgraded to V1.2, V1.3, V1.4, and so on. In other words, your software advances toward its final form with each step. It enables you to create user-friendly software and receive greater user feedback.
The steps in an iterative approach are as follows;
Shaped Like A V
The traditional waterfall model has been updated for use in this software development process. Rather than creating the full piece of software and then testing it. After developing software in a V shape, a rigorous validation and verification stage comes next.
Prior to beginning the phase execution, requirements are tested. This model seeks to manage the software’s overall quality. It is appropriate for small-scale software development, nevertheless.
- Development High-level design Low-level design
- Integration testing Unit testing
- system evaluation
- Validation testing
The model is referred to as risk-driven. Instead of moving forward in a sequential manner, this process curls. Additionally, it offers fresh elements for risk assessment in addition to the waterfall model’s greatest characteristics.
The spiral model emphasizes utilizing both top-down and bottom-up strategies. It separates the entire development process into different phases, which enables precise planning at the end.
Additionally, you can include individuals at each stage of the investigation and evaluation of your product.
- Planning Risk Evaluation
- Creation and approval
- Plan the next “loop” after evaluating the results
