Understanding the SDLC: Software Development Lifecycle Explained

Learn about the software development lifecycle (SDLC) and gain valuable insights into its essential phases, methodologies, and best practices. Enhance your understanding of this crucial process to drive successful software development projects.

Building great software is a big challenge, and development teams rely on the software development lifecycle (SDLC) to help them succeed. By providing a structured approach to software development, an effective SDLC helps teams:

Clarify and understand stakeholder requirements.

Estimate project costs and timeframes.

Identify and minimize risks early in the process.

Measure progress and keep projects on track.

Enhance transparency and improve client relations.

Control costs and accelerate time to market.

What is SDLC?

The software development lifecycle (SDLC) is a step-by-step process that helps development teams efficiently build the highest quality software at the lowest cost. Teams follow the SDLC to help them plan, analyze, design, test, deploy, and maintain software. The SDLC also helps teams ensure that the software meets stakeholder requirements and adheres to their organization’s standards for quality, security, and compliance.

The SDLC includes different phases, and each phase has a specific process and deliverables. Although SDLC meaning might vary for each development team, the most common phases include:

Requirements gathering and analysis: Business analysts work with stakeholders to determine and document the software requirements.

System design: Software architects translate the requirements into a software solution and create a high-level design.

Coding: Developers build the software based on the system design.

Testing: The software is tested for bugs and defects and to make sure that it meets the requirements. Any issues are fixed until the software is ready for deployment.

Deployment: The software is released to the production environment where it is installed on the target systems and made available to users.

Maintenance and support: This ongoing process includes training and supporting users, enhancing the software, monitoring performance, and fixing any bugs or security issues.

SDLC phases and how they work

Each phase of the SDLC has key activities designed to drive efficiently, quality, and customer satisfaction.

Requirements gathering and analysis

Accurate, complete, and measurable user requirements are the foundation for any successful SDLC project—to ensure that the software meets user expectations and to avoid costly rework and project delays. The IT business analyst:

Gathers requirements by conducting interviews, holding workshops or focus groups, preparing surveys or questionnaires, and observing how stakeholders work.

Evaluates the requirements as they relate to system feasibility, and software design and testing.

Models the requirements and records them in a document, such as a user story, software requirements specification, use case document, or process specification.

System design

Effective system design properly accounts for all documented requirements. In this phase, software architects use tools to visualize information about the application’s behavior and structure, including:

The unified modeling language (UML) to illustrate the software’s architectural blueprints in a diagram.

Data flow diagrams to visualize system requirements.

Decision trees and decision tables to help explain complex relationships.

Simulations to predict how the software will perform.

To support the distinct layers within a software application, software architects use a design principle called separation of concerns. A software program that’s designed to align with the separation of concerns principle is called a modular program.

Modular software design separates program functionality into interchangeable, independent modules, so that each module contains everything it needs to execute one aspect of the software’s functionality. This approach makes it easier to understand, test, maintain, reuse, scale, and refactor code.

In the coding phase, developers translate the system design specifications into actual code. It’s critical that developers follow best practices for writing clean, maintainable, and efficient code, including:

Writing code that’s easy to understand and read.

Using comments to explain what the code does.

Using version control to track any changes to the codebase.

Refactoring the code if needed.

Conducting a code review when coding is completed to get a second opinion on the code.

Providing code documentation that explains how the code works.

Before it’s released to production, the software is thoroughly tested for defects and errors.

The software test plan provides critical information about the testing process, including the strategy, objectives, required resources, deliverables, and criteria for exit or suspension.

Test case design establishes the criteria for determining if the software is working correctly or not.

Test execution is the process of running the test to identify any bugs or software defects.

Developers and quality assurance teams use automated testing tools to quickly test software, prepare defect reports, and compare testing results with expected outcomes. Automated testing saves time and money, provides immediate feedback, and helps improve software quality. Automated testing can be used for:

Unit testing: Developers test the individual software modules to validate that each one is working correctly.

Integration testing: Developers test how the different modules interact with each other to verify that they work together correctly.

System testing : Developers test the software to verify that it meets the requirements and works correctly in the production environment.

User acceptance testing: Stakeholders and users test the software to verify and accept it before it’s deployed to production.

There are three main phases to deploying software in a production environment:

The development team commits the code to a software repository.

The deployment automation tool triggers a series of tests.

The software is deployed to production and made available to users.

Effective software installation requires a consistent deployment mechanism and a simple installation structure with minimal file distribution. The team must also make sure that the correct configuration file is copied to the production environment and that the correct network protocols are in place. Before migrating data to the new system, the team also needs to audit the source data and resolve any issues.

Release management makes software deployment smooth and stable. This process is used to plan, design, schedule, test, and deploy the release. Versioning helps ensure the integrity of the production environment when upgrades are deployed.

Maintenance and support

After the software is deployed, the software maintenance lifecycle begins. Software requires ongoing maintenance to ensure that it operates at peak performance. Developers periodically issue software patches to fix bugs in the software and resolve any security issues.

Maintenance activities also include performance monitoring of both the software’s technical performance and how users perceive its performance. Providing training and documentation to users, along with addressing user issues and upgrading their systems to make sure they’re compatible with the new software, are also key components of the software maintenance lifecycle.

What are the SDLC methodologies?

In the world of software development, different methodologies serve as structured approaches to guide the process of creating and delivering software. These methodologies shape how teams plan, execute, and manage their projects, impacting factors such as flexibility, collaboration, and efficiency. Let's take a look at some of the more prominent SDLC methodologies.

Waterfall model

Introduced in 1970, the first SDLC approach to be widely used by development teams is called the waterfall model. This method divides the software development process into sequential phases. Work flows down from one phase to another, like a waterfall, with the outcome of one phase serving as the input for the next phase. The next phase can’t begin until the previous one is completed.

The waterfall model works best for small projects where the requirements are well-defined, and the development team understands the technology. Updating existing software and migrating software to a new platform are examples of scenarios that are well-suited for the waterfall model.

Waterfall model advantages

The straightforward process is easy to understand and follow.

An output is delivered at the end of each phase.

Project milestones and deadlines are clearly defined.

Waterfall model disadvantages

Lack of flexibility makes it difficult for development teams to adapt when stakeholder requirements change.

Once a phase is completed, any changes can be costly to implement and might delay the project schedule.

Testing does not take place until the end of the SDLC.

Agile methodology

The term “agile” describes an approach to software development that emphasizes incremental delivery, team collaboration, and continual planning and learning. Unlike the waterfall model’s sequential process, the agile methodology takes an iterative approach to software development.

Iterative software development speeds the SDLC by completing work in sprints, which are fixed project cycles that typically last between two and four weeks. Key terms include:

User stories: User stories are short descriptions of product requirements from the customer’s point of view. The most critical user stories are prioritized at the top of each sprint’s backlog of work.

Increment: The sprint’s output is called the increment. Each increment should be of potentially shippable quality, with all coding, testing, and quality verification completed.

Retrospectives: At the end of each sprint, the agile team conducts a retrospective meeting to evaluate the process and the tools, discuss what did and didn’t go well, and determine what to improve in future sprints.

The agile methodology is well-suited for projects that require flexibility and the ability to quickly adapt to changing requirements. Because it encourages collaboration, agile is also well-suited for complex projects where many teams work together.

Agile methodology advantages

Stakeholders and users can provide feedback throughout the SDLC, making it easier for developers to build software that meets their needs.

Incremental delivery helps development teams identify and fix issues early in the project before they become major problems.

Cost savings might be realized by reducing the amount of rework required to fix issues.

Retrospectives provide an opportunity for teams to continuously improve the process.

Agile methodology disadvantages

Requirements must be clearly defined in the user story. If not, the project can quickly derail.

Too much user feedback might change the scope of the project, cause delays, or make it difficult to manage.

Incremental deliverables can make it difficult to determine how long it will take to finish the entire project.

Agile frameworks

Agile methods are often called frameworks and the most common agile framework is called “scrum.” There are the three key roles on the scrum team:

The scrum master ensures that the team follows the scrum process and is continuously looking for ways that the team can improve while resolving issues that arise during the sprint.

The product owner takes responsibility for what the team builds and why they build it, along with keeping the backlog of work in priority order and up to date.

The scrum team members build the product and are responsible for engineering and quality.

The scrum team decides how to manage its own workload for each sprint based on the backlog shown on a task board. Team members participate in a daily scrum (or daily standup) meeting where each person reports on their individual progress. At the end of the sprint, the team demonstrates their potentially shippable increment to stakeholders, conducts a retrospective, and determines actions for the next sprint.

Kanban is another agile framework. Kanban is Japanese term that means billboard or signboard. Kanban boards visualize work items as cards in different states to provides at-a-glance insight into the status of each project and make it easy to identify any bottlenecks.

To help them work most effectively, development teams might adopt aspects of both the scrum and kanban agile frameworks.

Other popular SDLC methodologies

The iterative model  emphasizes continuous feedback and incremental progress. It organizes the development process into small cycles where developers make frequent, incremental changes to continuously learn and avoid costly mistakes. The iterative model is well-suited for large projects that can be divided into smaller pieces, and for projects where the requirements are clearly defined from the start.

The spiral model  combines the iterative and waterfall models. It takes an evolutionary approach where developers iteratively develop, test, and refine the software in successive cycles, or spirals. Large, complex, and costly projects are well-suited for this model.

The v-shaped model  emphasizes testing and validation in a sequential process. This model is very useful for projects in industries like healthcare, where thorough testing is critical.

The lean model  focuses on increasing efficiency throughout the development process. This model takes an iterative approach and is well-suited for projects where achieving short-term goals is a priority and when there’s frequent interaction between the development team and users.

SDLC best practices and challenges

The biggest challenges to a successful SDLC often stem from inadequate communication, planning, testing, or documentation. Best practices to address these issues include:

Collaboration between the development team, IT operations, the security team, and stakeholders.

Clearly defining user requirements and project deliverables, timelines, and milestones.

Detailed documentation of resources, schedules, code, and other deliverables.

Daily scrum meetings to identify and resolve issues.

Retrospectives to drive continuous improvement across the SDLC.

SDLC security

Due to increasing cyberattacks and security breaches, development teams are under pressure to improve  application security . SDLC security is a set of processes that incorporate robust security measures and testing into the SDLC. Best practices support the detection and remediation of security issues early in the lifecycle—before the software is deployed to production.

Security that empowers developers

To get ahead of security issues, some teams are using development platforms that build security analysis into their workflow. For example, the  GitHub platform  scans code for security issues as it’s written in the coding phase.

How does DevOps work with the SDLC?

DevOps  is an approach to SDLC that combines development (dev) and operations (ops) to speed the delivery of quality software. The core principles of this approach are automation, security, and  continuous integration and continuous delivery (CI/CD) , which combines the SDLC into one integrated workflow.

DevOps follows the lean and agile SDLC methodologies and emphasizes collaboration. Throughout the entire SDLC, developers, IT operations staff, and security teams regularly communicate and work together to ensure successful project delivery.

A well-structured SDLC helps development teams deliver high-quality software faster and more efficiently. Although SDLC methods vary by organization, most development teams use SDLC to guide their projects.

The SDLC helps development teams build software that meets user requirements and is well-tested, highly secure, and production ready. Popular tools that support the SDLC process include:

GitHub Actions to automate SDLC workflows.

GitHub security tools to help developers ship secure applications.

GitHub Copilot to developers write code faster with AI.

GitHub code review tools to help avoid human error.

Software de­velopment is defined as the process of designing, cre­ating, testing, and maintaining computer programs and applications. This diverse field combines creativity, engineering expertise, and problem-solving abilities to produce software that satisfies particular requirements and goals. Software developers, also known as programmers or coders, use a variety of programming languages and tools to create solutions for end-users or businesses.

Note : If you want to learn about Product Development, Please refer this: Product Development | Definition, Principles, Steps, Stages and Frameworks

Software developers develop the software, which itself is a set of instructions in order to perform a specific task. software have three types.

There are three basic types of Software

1. System Software

System software is software that directly operates computer hardware and provides basic functionality to users as well as other software for it to run smoothly.

2. Application Software

Application software is a software that is designed for end-user to complete a specific task. It is a product or programm that is only intended to meet the needs of end users. It includes word processors, spreadsheets, database management, inventory, and payroll software, among other things.

3. Programming Software

Programming software is a software that is designed for programmers to develop program. It consist of code editor, compiler, interpreter, debugger etc.

Under Software Development, developers develop all the software that comes under these three category.

Software de­velopment is a well-structured process with several key stages. While different methodologies exist, such as Agile and Waterfall, most software development projects include the following steps:

1. Requirement Analysis :

• The first step in software development is understanding the requirements and based on that requirement gathering happen. This stage involves identifying the needs, objectives, and constraints of the project. The goal is to define what the software should do and what problems it will solve.
• In the design phase, the software’s architecture and user interface are developed. This step defines how the software will work and how users will interact with it. Design includes creating wireframes, prototypes, and system architecture diagrams.
• After comple­ting the architectural design phase­, developers move­ on to creating detailed de­signs for each component of the syste­m. This includes designing not only the use­r interface but also encompassing database­s and APIs. The intricate decisions made­ in these detaile­d designs provide valuable guidance­ throughout the coding phase.

3. Implementation

• The most important phase of the Software Development is the implementation phase, which comes after the design phase. This phase will see the implementation of the design phase’s output.
• All of the planning done in the planning phase and the designing done in the designing phase are implemented in this phase. Physical source code is created and deployed in the real world during this phase.

4. Testing:

• De­velopers utilize unit te­sts to evaluate small code compone­nts, such as functions or methods. These te­sts play a crucial role in identifying and resolving bugs within isolate­d elements.
• Integration testing evaluate­s the smooth functioning of various software components. Its purpose­ is to ensure seamle­ss interactions betwee­n modules and efficient data transfe­r among them, resulting in a robust system.
• In order to ensure that the­ software meets all the­ specified require­ments, system testing e­valuates it as a whole. This comprehe­nsive evaluation includes functional, pe­rformance, security, and other ne­cessary types of testing.
• User Acce­ptance Testing (UAT) occurs during the phase­ where end-use­rs or clients validate the software­ to ensure it mee­ts their requireme­nts. Identified issues or discre­pancies are promptly addresse­d before procee­ding with deployment.

5. Deployment:

• Before deployment, the development team configures the target environment, whether it’s on-premises servers, cloud-based infrastructure, or end-user devices. This may involve setting up servers, databases, and configuring software dependencies.
• Developers carefully plan the process of deploying software, which includes aspects such as data migration strategies, software installation procedures, and contingency measures for unexpected issues.
• The software­ is deployed to end-use­rs or production environments. Ongoing monitoring is critical for quickly identifying and addressing any issues that may arise following the deployment.

6. Maintenance and Updates:

• Once­ the software has bee­n deployed, it is common for issues and bugs to arise­. The dedicated te­am of developers active­ly works on identifying, fixing, and thoroughly testing these­ problems. Regular updates are­ provided to address any nece­ssary improvements or changes that may arise­
• Feature­ enhancements are­ made to the software as use­r needs evolve­ or new requireme­nts arise. Develope­rs consistently implement ne­w features and improveme­nts in response to these­ changes.
• Regular security updates are crucial to address vulnerabilities and protect the software from cyber threats.

7. Documentation:

• The software developer provides use­r guides, manuals, and online help docume­ntation to assist end-users effe­ctively navigate its feature­s.
• Deve­lopers are responsible­ for creating technical documentation that outline­s the architecture, code­ structure, and APIs of a system. This documentation is crucial in he­lping future develope­rs comprehend and maintain the software­.
• Collaborative Nature: Software development is a collaborative process that involves a diverse group of professionals, including developers, designers, project managers, and stakeholders. Software project success is heavily dependent on effective communication and seamless teamwork.
• Continuous Learning : In Software Development it’s super important to keep learning because things are always changing. New ways of writing code, tools, and technologies are always popping up. To do well and keep up, programmers need to keep on learning and getting better at what they do. It’s like an ongoing adventure of picking up new skills to stay on top of the game.
• Problem-Solving: Deve­lopers play a crucial role as problem solve­rs. They actively identify and addre­ss issues, craft innovative solutions, and optimize code­ to achieve the de­sired outcomes. Problem-solving skills lie­ at the heart of the software­ development proce­ss.
• Creativity: When Developers making computer programs, it’s not just about following rules . There’s also room for being creative. Coding needs a lot of attention to detail and clear thinking, but it’s also a chance to let developers imagination run wild.
• Quality Assurance : In development, ensuring the­ quality and reliability of the software is a crucial aspe­ct. To ensure exceptional results, the development cycle includes stringent testing and quality assurance procedures.

Software development is critical because it creates the computer program and apps that we use every day, allowing things to run more smoothly and making our lives easier. It’s like the hidden magic that makes technology work for us.

Software Development Assignment : Selection Of System Development Methodologies

Task: To successfully complete the assignment, you should:

Identify factors that may determine the appropriateness of a particular development approach for an organisation or project – for example organisational size, team size and whether the system is mission-critical may be important. Use the unit readings and other literature you identify to do this.

Review the system development methodologies that Innovative Solutions use in terms of their characteristics, benefits and drawbacks:

• Rational Unified Process

Consider when the use of each methodology is appropriate.

Propose guidelines to help assist in the selection of which of these system development methodologies to use.

Create a report based on what you have found out. It should include some information about the factors that determine choice of methodology, some information about the methodologies, and MUST provide well explained guidelines. The report will be used by employees of the Innovative Solutions, so should be written in a style that will be accessible to them (i.e. not as an academic essay).

Introduction: Organizational development is the preparation of systematic transformation in the values & attitude of the work staff for individual as well as corporation growth. There are continuous changes taking place in the current industry irrespective of the field a company belongs to. With OD, employees will be able to respond aptly to those technological advances.

A highly functional framework, the utilization of SDM or Software Development Methodology assists the project teams in controlling & planning the expansion of IT procedures, Services & Products (Saarinen & Saarinen, 1990). The use of SDM in manifold instances enhances quality & productivity of system development. Every SDM will be different based on the nature of IT projects. Each methodology is directed towards particular projects that will position the brand in the highest rank for it to be competitive.

The objective of this particular software development assignment is to apprehend what system development methodologies are & the comparison of two different system development methodologies in context to a company named Innovative Solutions. Also, the software development assignment will review the possible approaches & factors that the employees can consider for the various development projects. This structure of the software development assignment will determine the criterion for assessment of the given two methodologies.

Factors affecting the selection of system development methodologies The creator of finest utility software, Innovative Solutions is a software development firm whose services & products enlarge the prospects & innovation for their users. As the company’s goal to fabricate supreme quality applications, it is imperative for the organization to depend on System Development Methodologies. It is also quite important to have the best tools for forming the reports (TopITSoftware, 2020) However, with each different application or project, the particular development approach also changes that has to be selected correctly so that the clients gain benefits.

Emphasizing on the perspective of the employees holding positions like system personnel, functional managers, external consultants, information systems manager, etc; the factors that affect the implementation of System Development Methodologies are (Roberts, Gibson, Fields & Rainer, 1998):

• Clarification of primary requisites – Every software development has a beginning point which gets represented by the correct definition of the exact requisites from the very commencement of any project. A look on the iterative sessions can also be helpful as the users specify the initial requirements in details over here.
• Estimated development time & costs – The specifics of every project is different which is why the development time can vary as well. Hence it has to be chosen as per the urgency of the user. However, the development costs keep changing that depends on the operations in the execution of the requisites that go through transformation in the development stage.
• Requirement alterations during the entire development stage – Requirement & system changes can be brought along even in delayed life cycle stages as it has to be flexible enough to adapt to client requirements. But the cost becomes high in the later stages.

Reviewing two major system development methodologies Innovative Solutions utilize two system methodologies depending on its characteristics, drawbacks & benefits. The Review of those two System Development Methodologies are as follows:

RUP or Rational Unified Process: A framework for finest project software development, the Rational Unified Process is a library equipped with the best practices in respect to the current industry that assists developers in small & big projects (Powell-Morse, 2017). The development of organization specific software carries out in four phases:

• Elaboration
• Construction

This type of methodology is appropriate for unwavering organizational environment just like Innovative Solutions. It also renders manifold applications for all users.

SCRUM: Organizations when developing technology products require assistance of a responsive software development structure that can be acquired through SCRUM methodology. It is also utilized for manifold complex projects. Client requisites are volatile which is why this flexible methodology is apt in arenas of maintenance & product development. The methodology can also alter software terms based on changing customer requirements.

When is the utilization of RUP appropriate? Firstly, the disciplines whose performance is carried out within Rational Unified Process for Software Development are design & analysis, business modeling, deployment, project management, implementation & a lot more. This methodology can be adapted as per manifold factors like:

• The area of software operation
• Operating system size
• Skills of the development team
• Project organization method.

The projects that carry complex elements can be best apprehended with RUP methodology. The approaches for the adaptation of this methodology are (Lee, 2012):

• Adaptation in one step for every project
• Describing a subset of the structure to the company
• Adapting by taking the project categories into consideration

Project success is guaranteed as this methodology is based on contemporary software engineering practices like:

• Visual modeling
• Iterative development
• Verification of change control
• Requirements management

When is the utilization of SCRUM appropriate? The software development projects that require quick turnaround times and carry tighter schedules must revert to SCRUM methodology. For instance, while fabricating ERP application custom reports, a SCRUM procedure will be required as reports develop over time for greater functionality as per user feedback (Murray, 2018). These are iterative processes. Some of the prescribed elements that make SCRUM lightweight are:

• Three meetings – Retrospective, sprint planning & daily scrum
• Three roles – Product owner, team & scrum master
• Three artifacts – Sprint & product backlog & burndown chart

SCRUM methodology is highly swift & responsive to client needs that makes it agile. It is an amalgamation of concepts & practices around which procedures can be developed.

The assumptions made by this approach regarding practicalities & priorities of the project to be completed depend on these factors:

• Reduction of scope takes place for attaining schedule
• Success is demonstrated with the attainment of planned scope
• Tighter constraint is a possibility depending on schedule
• Schedules are sometimes extended as well for obtaining scope

Guidelines to consider while selecting system development methodologies Rational Unified Process: The aspects related to this methodology depend on a bunch of building blocks that demonstrate what has to be produced, the person in charge of the production, the method of carrying out the production & the time frame for completing the production.

• Workers – The duties of the work staff either as teams or individuals working on a particular project is important for producing artifacts
• Activities – By this it refers to the unit of operations that workers perform
• Artifacts – Tangible solutions that are derived from the procedures that range from code functions to life cycle models
• Workflows – It represents a series of activities for the development of artifacts

SCRUM: Tasks are always prioritized by utilizing the 30-days sprints by SCRUM methodology. A SCRUM master is the one who leads small teams. The teams work no particular activities independently and they are joined by the SCRUM master later for analyzing the progress. Choosing the apt master is vital for the successful completion of all projects. The selection criteria are:

• Servant Leadership personnel – A candidate who will be serving towards all clients is the apt one. He will take care of the fact that the priority of other people are met & served.
• Problem solving talent – This primary criterion in a person states that he has the required experience for helping solve any challenge for the team.
• Commitment – The master has to apprehend commitment so that he can offer the team with a favorable work environment for successful delivery of projects.
• Availability – It is the duty of the master to be available at all times for scheduling and facilitating meetings that incorporates daily standup & release planning meetings

Deciding on the apt systems development methodologies As we know that System Development Methodologies are a bunch of practices utilized by a company for managing projects and meetings goals, Innovative Solutions must consider these factors before deciding on a particular methodology:

• Particular processes must be present for analyzing each methodology for guaranteeing that it fits the requirements
• Methodology selection can also depend on external & internal factors

Factors to be taken into account while selecting methodology:

• Cost & size of the project
• The structure of the company
• Strength, opportunity, weakness & threat in business
• Complexity of the project
• Overlooking if the internal infrastructure supports the specific methodology

Assessing methodologies: The next step includes a process development for discovering the drivers’ specific to the particular projects so that the best choice can be made. The drivers are:

• Stakeholder requirements
• Budget limitations
• Deliverables

Some RUP advantages

• Embedded with the adaptive abilities of managing changing requisites via life cycle development.
• Focuses on the requirement for accurate documentation & correct execution.
• Makes integration occur via development amidst construction phase in which the coding is taking place.

Some SCRUM advantages

• The ability of completing projects 40% faster than any other methodology. This is possible due to the availability of real time updates.
• Offers the team members an opportunity for bringing out their creative side as this development system comes in a self-managed shape (Novoseltseva, 2017).
• SCRUM provides the developers with the correct relevant information as it utilizes relevant metrics.

Conclusion As Innovative Solutions deal with clients having massive in-house IT departments as well as clients having few in-house expertises, both the System Development Methodologies can be selected. In this software development assignment it is observed that the selection will mainly depend on the nature, budget & urgency of the project.
