When developing software, the project’s life cycle must adhere to particular guidelines, which are outlined in the ten phases of software product development. Each of these processes necessitates the development of software architecture and system design.
Software developers prepare a document called a Software Requirement Specification (SRS) that serves as a guideline throughout the development process and comprises various product requirements. The final SRS includes software specifications, structure, and features. This document acts as a contract between the software developers and the clients.
What is the Life Cycle of Software Development?
The Software Development Life Cycle (SDLC) outlines the steps involved in creating software using standard business techniques. The process is commonly broken down into eight or ten phases, each of which includes one or more of the following: planning, requirements, design, construction, documentation, testing, deployment, and maintenance. Many project managers may integrate, split, or skip certain stages based on the project’s nature, scope, and size.
SDLC is a recursive process in which each step has an effect on the activities of the next stage and provides direction for what will happen in the future. The SDLC is a way to track and analyze the progress of a project so that the result is more efficient business processes at every level.
The demand for software and programmers grows as the amount of processing power increases. Consumer expectations must be met and even surpassed while cutting down costs and speeding up software deployment. By identifying and fixing inefficiencies and unnecessary expenses, the SDLC makes it possible to achieve these goals. The SDLC, hence, makes up the building blocks of every software development project.
The Importance of Software Product Development Life Cycle
The software development life cycle provides benefits to software development in some of the ways mentioned in this article. First of all, it offers an efficient structure and mechanism for developing software applications. Secondly, it aids in good planning before beginning real construction. SDLC also enables developers to examine requirements. It further aids in the reduction of superfluous expenses during development. During the early stages, developers can estimate expenses and avoid costly blunders.
It helps developers to design and construct high-quality software solutions. This is because they follow a methodical approach that enables them to evaluate the program before it is released. It serves as a foundation for measuring the software’s efficacy, which improves the program even more. When designing a new software product using this methodology, the following are some of the most important actions that need to be taken in the development process.
The Ten Steps of the Software Product Development Life Cycle
As mentioned earlier, the software product development life cycle comprises a few crucial steps.
1. Market Research
The software product development life cycle is an ongoing process that consists of ten major stages. The first step is market research. Market research is the process of analyzing a market to determine how customers want a product to work and whether it is feasible. The next step is product development. Product development focuses on launching a Proof of Concept or a working software product. This process is often the most uncertain because it involves working on an entirely new idea.
Product development requires market research to identify the needs of the customer and determine the appropriate marketing mix to reach the target market. The market research also helps to understand the risks and opportunities of a particular idea. The goal of this process is to create the best possible solution for a target market so that the product is appealing to the right people. This step forces product developers to step outside of their bubble and evaluate the needs of their target market.
2. Concept Creation
The concept creation phase of the software product development life cycle is a fundamental stage in developing a software product. It requires the organization of ideas, identifying which ones are viable, and determining which are not. During this step, some ideas are eliminated, for various reasons, such as economic, legal, and efficiency. However, many of these ideas end up becoming a part of the final product.
First, it is necessary to understand how the concept works. For example, how does the software system work? How do users interact with it? What is the target audience of the product? How do you plan to monetize it? What are the business goals of the product? These are all important questions that need to be answered by the software development team. During the design stage, the software development team can gather information to develop a prototype.
Next, the software development team must gather customer input. The project manager and business analyst are responsible for gathering the required information. The core understanding of the product is essential before it can be built. The project team can then create an appropriate roadmap to meet the requirements.
The next stage is product planning. This phase is critical because it establishes the product’s features, usability, and business viability. Successful product managers make use of the entire development team during the planning phase.
The planning stage involves drafting the SDLC process and meeting different groups to determine the scope of the project. This phase will provide time targets for each development stage, as well as the resources needed to complete the project. This stage also specifies the desired production environment for the developers. Once the planning phase is completed, the project will move to the development stage.
The planning phase of the software product development life cycle involves sharing key learning outcomes, such as customer demand, technical requirements, and market fit. It is also important to break the planned release into small and manageable steps. To do so, you should document the user stories for each feature and rank them according to importance, difficulty, and priority. Then, you can set a timeline for the completion of each of the steps involved. All software product development life cycle phases should work in tandem.
4. Creating an SRS
As mentioned already, an SRS is a document that states the functions and constraints that software must fulfill. It is the foundation for the entire project and provides critical information to the development team. It is also known as the “parent” document because all subsequent project management documents are based on it.
The SRS should be accessible to the development team. It should contain all the requirements and be consistent. However, it must be detailed enough to do the job without limiting the development process.
A well-written SRS should include general information, functional and non-functional requirements, security specifications, performance, use cases, and feedback. Besides, it should be scalable and easily modifiable. The developer should also be able to modify the requirements if necessary. An SRS should contain information that can be used in the future and will not be outdated. In addition to the above-mentioned advantages, SRSs should be flexible enough to accommodate future changes.
5. Design Development
The software product development life cycle has a logical structure. Each phase produces deliverables required by the next step. While the requirements phase includes defining the software requirements, gathering and documenting the client’s requirements, and allocating resources for each phase, the design phase involves decisions regarding the design and architecture of the software solution. Design documents, coding guidelines, and discussions on frameworks and runtimes can all be part of the process.
The design phase is one of the earliest phases of the software development process. Once the development team has gathered requirements, the software team will create a quick prototype. The customer will review the prototype and give feedback. If the customer is satisfied with the prototype, the team will move into the production phase. The developers will then continue testing and maintenance until the software is ready for go-live.
6. Developing the Software
The software product development life cycle begins with the creation of specifications, or requirements for the software. This phase is critical for determining whether the process for developing the software product is feasible and how much work is required to overcome any roadblocks that may occur. The next step in the process is testing to determine if the initial requirements of the software product are met. During the development stage, software architecture (the organized flow of software code) is created.
The final step in the software development process is release. This phase involves testing, implementation, and maintenance. It may be a straight release for simple projects, or staggered releases for complex ones. During this phase, the team will address requests for bug fixes, enhancements, and new features. This stage helps in reducing project costs while increasing the quality of the software produced. In addition to that, the software development life cycle also helps in making the team aware of any problems early on and preventing them from becoming complicated later.
In the ten steps of the software product development life cycle, testing plays a major role. Developers are responsible for ensuring that a product meets the requirements and is compatible with the business goals. It also involves research and development of automated test scripts, which can then be used to validate the quality of the product. In the case of errors, developers can go back to the previous step and fix them before moving on to the next step.
The pre-alpha stage is the first step in software launch. This stage is used to identify the functionality of the software application and ensure stable transitions between phases of the software release life cycle. Beta testing is often conducted at the client’s site and helps to ensure the software is fully functional before it is released. Before the release of the product, the developer must make sure that the product will meet its goals and meet the requirements of the client.
During the low-level design phase, the developer performs unit testing to test the functionality of a particular module. Later, he performs integration testing. This stage checks the functionality of an entire system and is associated with the final validation stage. In both phases, the customer must sign off for the software before it is ready for go-live. Afterward, regression testing will be performed in the actual production environment.
8. Creating a Marketing Strategy
Software product development involves several stages, including defining the product’s needs and creating a marketing strategy. Throughout the process of the software product development life cycle, the team communicates with stakeholders to identify market needs and key areas of differentiation. During this step, the team can gather information about the product’s users and customers so that it can respond quickly to changing needs and improve its features.
9. Preparing Launch
The software product development life cycle starts with a list of features that define a product. It then describes the stimulus and response sequences and launches the product. It also describes external interface requirements and product interfaces.
During the viability phase, the software prototype is tested to make sure it can solve the desired problems. Once this step is complete, the software product is ready for marketing and deployment. Once the software has successfully been tested, it is ready for the market.
After acceptance testing, the next phase of the SDLC is the integration of the various modules into the final product. Unit testing will ensure that the different modules are properly integrated and work together. After the product has been launched, SDLC continues with continuous monitoring to ensure that there are no problems or challenges that could hamper the process.
10. Post-Launch Maintenance
The post-launch maintenance of the software development life cycle involves addressing issues identified during the initial phases of the project. Post-launch maintenance is vital for the continued functionality and performance of a product. After the product is developed, it must be tested and maintained, and the process of implementing new modules and systems requires thorough testing and analysis.
During this phase, developers perform whole-system and module testing, as well as acceptance testing. Acceptance testing involves a series of activities for customers to evaluate the software modifications and identify any ongoing issues. The testing of the modified software also helps in identifying potential issues and generating recommendations for more efficient implementation.
During the post-launch maintenance, the team must begin marketing the product to ensure that it meets customer needs and meets user expectations.
They must also analyze user feedback to make any necessary changes, and gather information on overall satisfaction. Additionally, the developers should start working on any issues that have been reported by users. In addition, they should keep in mind that the software will most likely require updates and changes throughout its lifespan.
There are several stages to the SDLC process. Each of them focuses on different aspects of the software development life cycle. The length of the SDLC process is dependent on the complexity of the software and the requirements of the application.
