5. Software development life cycle (SDLC)

The SDLC standardizes how software goes from an idea to a full product. Each stage has clear tasks to ensure consistency and quality. In larger teams, each step may involve different stakeholders, from business analysts to DevOps.

Planning & analysis in paragraph

During planning and analysis, teams define the project’s scope, check feasibility, and set goals. In Singapore, they also consider data laws like PDPA to avoid legal issues [1]. Budgets, timelines, and success metrics are established, and stakeholders such as clients or end-users provide input on essential features.

Requirements management in paragraph

Requirements management involves gathering user stories, performance targets, technical constraints, and budgets. The final outcome is a documented list of “must-haves” for developers. Some companies create detailed requirement specifications, including functional and non-functional aspects, ensuring compliance with local or industry-specific rules.

Design in paragraph

The design phase includes making blueprints like UI/UX prototypes, architecture diagrams, and database structures. Teams decide how external or internal APIs will connect with the application [2][8]. Designers produce wireframes to show user flows, while architects choose modules, frameworks, or patterns such as MVC or microservices.

Model building (prototyping) in paragraph

Model building involves creating early versions (prototypes) to test big ideas. Some teams use Generative AI to speed up basic layout or code creation [2][8]. Prototypes help gather quick feedback and reduce major changes later. They might be clickable front-end mockups or a minimal back-end feature for early testing.

Constructing code in paragraph

Constructing code turns designs into a working product. Developers follow coding standards, use version control like Git to track revisions, and perform peer reviews to spot errors. This phase transforms static designs into functional software, with an emphasis on security, performance, and code style.

Testing in paragraph

Testing uses both automated and manual methods to find bugs, security gaps, or performance problems. CI/CD pipelines catch issues whenever new code is merged. Testers handle unit tests, integration tests, and user acceptance checks. They may also do security scans or penetration tests, ensuring the software meets Singapore’s compliance standards.

Deployment in paragraph

Deployment moves the finished software to live servers or cloud environments. IaC scripts automate server setup on platforms like AWS or Azure [12][19]. Large teams often create a staging environment for final checks, and DevOps practices help shorten downtime during rollouts. Once deployed, the software is accessible to end-users.

9 common software development models

Different models outline how teams follow the SDLC. Your choice depends on project size, complexity, and flexibility. Many companies blend these models to fit specific needs. Below, each model is explained first, then followed by additional details.

Waterfall

Waterfall is a linear process that flows in stages: planning, design, coding, testing, and maintenance. It works best for projects where requirements are stable and unlikely to change mid-project. Once you finish one phase, you move to the next, which reduces overlap but makes it costly to revisit earlier phases if new insights emerge.

V-Shaped

V-Shaped development pairs each step of coding with a corresponding test phase. While it ensures thorough verification and validation, it’s not ideal if needs shift often. This model is common in strict fields like healthcare or defense, where each step must pass certain checks before moving on.

Iterative

Iterative development builds software in repeated loops, adding features or refining parts each time. It catches issues sooner than a fully linear approach. Teams learn from each cycle and gradually reach a final product that’s shaped by ongoing feedback and incremental improvements.

Agile

Agile uses short sprints, frequent feedback, and welcomes changing requirements. Popular frameworks include Scrum and Kanban. This model suits Singapore’s startup world, where time-to-market is critical [8]. Each sprint delivers a functioning piece, and teams rapidly adjust plans based on user input.

DevOps

DevOps merges development with IT operations to automate releases and ensure stable code. It uses continuous integration (CI) and continuous delivery (CD) to catch errors fast. This culture breaks down silos so developers and ops teams collaborate, speeding up deployment and lowering downtime.

Rapid application development (RAD)

RAD focuses on quick prototypes and user feedback. It’s fast and flexible but can require rework if early assumptions are wrong. This model often suits GUI-based apps or in-house tools. Users see results quickly, guiding immediate changes without lengthy planning.

Spiral

Spiral is a hybrid that combines Waterfall’s structured steps with iterative loops. It’s good for large or high-risk projects where constant risk analysis is crucial. Each loop includes planning, risk assessment, and prototyping. This approach helps tackle complex systems needing multiple revisions.

Lean

Lean aims to remove waste and deliver value swiftly, taking cues from manufacturing. Teams rely on data-driven decisions and continuous improvement. They cut overhead, ditch unused features, and zero in on what users actually need.

Big Bang

Big Bang involves minimal planning before coding starts. It’s risky because projects can veer off if the scope isn’t well defined. This approach might be fine for small demos or experimental work, but it’s hard to maintain or scale for full production.

Types of software development specializations

Cloud-native development

Cloud-native development focuses on designing apps for cloud environments, using microservices, containers, or serverless architectures. Many Singapore firms choose hybrid or multi cloud setups [2][12]. This approach scales quickly and cuts infrastructure costs, but requires skills like Docker, Kubernetes, or AWS.

Low-code/no-code development

Low-code or no-code platforms let non-technical people build apps with simple, drag-and-drop interfaces. This solves some of the developer shortage [7]. Tools like OutSystems or Microsoft Power Apps can handle many basic tasks, but very complex apps still need full-code solutions.

Front-end development

Front-end development centers on how websites and apps look and feel. It uses HTML, CSS, and JavaScript frameworks like React, Angular, or Vue. A bad front-end can scare users away, so good UI/UX is crucial. Devs here also track user behavior to improve site flow.

Back-end development

Back-end dev handles server logic, data management, and security. It’s essential for apps that handle heavy traffic or sensitive data. Common languages include Java, Python, Node.js, and Ruby. This role ensures data flows well, often tying front-end features to microservices or APIs.

Full-stack development

Full-stack devs cover both front and back-end, bridging any gaps. They can reduce delays by handling tasks across the stack. However, being good at all parts is challenging. Still, full-stack devs often lead small teams where flexibility is an asset.

AI-powered software development

AI-powered development adds machine learning or data analysis features to software [2][8]. Singapore’s Enterprise Compute Initiative invests SGD 150 million in AI [4][5][14]. This helps developers create chatbots, predictive models, or recommendation engines. AI dev often overlaps with data science, focusing on algorithms and data pipelines.

AI and software development

Code generation & autocompletion

AI can help generate or suggest code snippets. This saves time on routine tasks and lets devs focus on bigger problems. Tools like GitHub Copilot or Tabnine can offer workable prototypes for basic features.

• AI speeds up code writing.

• Developers still check and refine the AI’s output.

AI in testing & debugging

AI-based scripts can create tests, spot performance gaps, or find security flaws. This leads to faster fixes and more stable apps. Some solutions scan code for vulnerabilities or inefficiencies.

• Less manual testing is needed.

• Fewer hidden issues slip through.

Deployment optimization

AI also manages releases, analyzing each code update for issues. Monitoring tools with AI can catch unusual server loads or memory leaks. Automated scaling can handle sudden user spikes.

• Reduced downtime during updates.

• Real-time alerts for quick responses.
