System Development Life Cycle SDLC

There is a lot of literature on specific systems development life cycle (SDLC) methodologies, tools, and applications for successful system deployment. Not just limited to purely technical activities, SDLC involves process and procedure development, change management, identifying user experiences, policy/procedure development, user impact, and proper security procedures. Books such as David Avison and Guy Fitzgerald’s Information Systems Development and Alan Daniels and Don Yeates’ Basic Systems Analysis, delve into the intricacies of information systems development lifecycles.

Developers will follow any coding guidelines as defined by the organization and utilize different tools such as compilers, debuggers, and interpreters. The final phase of the SDLC is to measure the effectiveness of the system and evaluate potential enhancements. For example, as the system analyst of Viti Bank, you have been tasked to examine the current information system. Customers in remote rural areas are finding difficulty to access the bank services. It takes them days or even weeks to travel to a location to access the bank services.

System Development Life Cycle (SDLC)

The new seven phases of SDLC include planning, analysis, design, development, testing, implementation, and maintenance. It’s linear and straightforward and requires development teams to finish one phase of the project completely before moving on to the next. The development stage is the part where developers actually write code and build the application according to the earlier design documents and outlined specifications. The System Analyst works on high-level system reviews to assess if systems and infrastructures operate effectively and efficiently. System analysts research problems, find or develop solutions, recommend a course of action, communicate and coordinate with stakeholders, choose resources, and design action plans to reach a goal and meet predefined requirements. They are experts at studying a system, process, or procedure to come up with the best solutions.

The testing stage ensures the application’s features work correctly and coherently and fulfill user objectives and expectations. The next stage of a system development project is design and prototyping. Most of the information generated at this stage will be contained in the SRS.

Basic 6 SDLC Methodologies

Create a timeline with milestones and dependencies to track progress, and set up automated alerts to notify you as anything changes. Share your plan with your team and key stakeholders to provide visibility, and assign tasks to individuals to ensure nothing slips through the cracks. Regardless of the process implemented and the tools used, all require the crucial element of documentation to support findings, close iterative phases, and to analyze success. Today’s increasing demand for data and information security also factor into the overall planning, training, testing, and deployment of a system.

Lean is about only working on what must be worked on at that specific moment. The project team is focused on finding opportunities to eliminate waste, to drop unnecessary things like meetings, and minimising documentation. The difference with the Agile approach in software is the focus on customer satisfaction throughout the entire lifespan of a system. During the fifth phase the system is installed in the production environment. Many organisations opt to have the system tested elsewhere first, in a special testing environment. By adding new steps, developers could define clearer and more effective actions to reach certain goals.

IV. Systems Development Life Cycle

The Iterative model incorporates a series of smaller “waterfalls,” where manageable portions of code are carefully analyzed, tested, and delivered through repeating development cycles. Getting early feedback from an end user enables the elimination of issues and bugs in the early stages of software creation. These are the approaches that can help you to deliver a specific software model with unique characteristics and features. Most developers and project managers opt for one of these 6 approaches. Now that you know the basic SDLC phases and why each of them is important, it’s time to dive into the core methodologies of the system development life cycle. In the development stage of SDLC, the system creation process produces a working solution.

RAD’s development model was first conceived back in the 80s to solve the need of developers looking for a more effective solution than the traditional Waterfall. One of the biggest faults of the Waterfall methodology, and one that most developers complain about, is the complexity to change core functions and software features. In RAD, the development evolution is continuous and flexible to suit changing business needs, which is a must in today’s modern environment. In the design phase, project members define the structure of project components as well as key elements of the system by defining the interfaces that will exchange data within the workflow. It’s very common for the project teams to use UML diagrams in the design phase to design the system’s architecture.


A software development lifecycle (SDLC) model conceptually presents SDLC in an organized fashion to help organizations implement it. Different models arrange the SDLC phases in varying chronological order to optimize the development cycle. Having separate build and production environments ensures that customers can continue to use the software even while it is being changed or upgraded.

With the vision of meeting the customers’ needs, the bank has requested your services to examine the current system and to come up with solutions or recommendations of how the current system can be provided to meet its needs.

9.6 Security Standards for Systems Development

The software development life cycle (SDLC) is the process of planning, writing, modifying, and maintaining software. Developers use the methodology as they design and write modern software for computers, cloud deployment, mobile phones, video games, and more. Various SDLC methodologies have been developed to guide the processes involved, including the original SDLC method, the Waterfall model. Other SDLC models include rapid application development (RAD), joint application development (JAD), the fountain model, the spiral model, build and fix, and synchronize-and-stabilize.

  • This procedure where the care is taken for the developed product is known as maintenance.
  • Around seven or eight steps appear commonly; however, there can be anywhere from five upwards to 12.
  • During this stage of the system lifecycle, subsystems that perform the desired system functions are designed and specified in compliance with the system specification.
  • Also, during the analysis phase, the team defines the inputs and outputs of the data flow in and out of the system by undertaking a thorough system analysis of the business processes that need to be covered and solved by the future system.
  • Many organizations subdivide their SDLC methodologies into a larger number of phases than the five referenced in NIST guidance, potentially offering closer alignment of SDLC phases and corresponding RMF tasks.
  • This stage includes the development of detailed designs that brings initial design work into a completed form of specifications.
  • The Agile model has existed for a long time, and still hasn’t lost its punch.

As a rule, these features help to finalize the SRS document as well as create the first prototype of the software to get the overall idea of how it should look like. All three of these methods are popular since they allow for extensive iteration and bug testing before a product is integrated with greater source code or delivered to market. Developers clearly know the goals they need to meet and the deliverables they must achieve by a set timeline, lowering the risk of time and resources being wasted. T’s important that the software overall ends up meeting the quality standards that were previously defined in the SRS document.

SDLC: 7 Phases or Stages of the System Development Life Cycle, Models, Perks & More

The analysis stage includes gathering all the specific details required for a new system as well as determining the first ideas for prototypes. In systems design, functions and operations are described in detail, including screen layouts, business rules, process diagrams, and other documentation. Modular design reduces complexity and allows the outputs to describe the system as a collection of subsystems. An output artifact does not need to be completely defined to serve as input of object-oriented design; analysis and design may occur in parallel. In practice the results of one activity can feed the other in an iterative process. This may involve training users, deploying hardware, and loading information from the prior system.

Hire Asp Net Developers Hire Asp Net Developer

For projects with a more significant focus on maintainability, testability, and scalability, MVC is the better option. MVC, on the other hand, uses a more lightweight approach and follows a model-view-controller (MVC) pattern. It provides a separation between the application’s data, user interface, and logic, allowing for more flexibility and maintainability. It’s also more testable than Web Forms thanks to this separation of concerns. In .NET and its frameworks, it’s a compiler that devs use to convert intermediate code into native code more easily.
