What Is the Software Development Life Cycle? SDLC Explained
Approaching their introduction without strategy or planning will likely result in failure and disaster, sometimes causing harm to patients. In this chapter, we describe the system development life cycle (SDLC), a common framework for the introduction for new information systems in organizations. The SDLC is used by clinical organizations to systematically approach the introduction of new information systems.
This stage includes the development of detailed designs that brings initial design work into a completed form of specifications. This work includes the specification of interfaces between the system and its intended environment, and a comprehensive evaluation of the systems logistical, maintenance and support requirements. The detail design and development is responsible for producing the product, process and material specifications and may result in substantial changes to the development specification. Systems analysis and design (SAD) can be considered a meta-development activity, which serves to set the stage and bound the problem. SAD interacts with distributed enterprise architecture, enterprise I.T. Architecture, and business architecture, and relies heavily on concepts such as partitioning, interfaces, personae and roles, and deployment/operational modeling to arrive at a high-level system description.
Development Phase
This generic SDLC model, designed by the National Computing Center of the United Kingdom in the late 1960s, was described in 1971 by A. You needn’t worry any longer as the search for answers to the latest security issues is over. Learn how embracing the benefits of single delivery platform will help protect your business. SDLCs can also be more specifically used by systems analysts as they develop and later implement a new information system. By developing an effective outline for the upcoming development cycle, they’ll theoretically catch problems before they affect development. This allows any stakeholders to safely play with the product before releasing it to the market.
Each phase has its own mini-plan and each phase “waterfalls” into the next. The biggest drawback of this model is that small details left incomplete can hold up the entire process. Becoming a software developer requires learning the key skills, programming languages, and concepts needed to build software products. These days, many people are successfully pivoting or switching their careers from education, the service industry, and more to coding and development. They may complete bootcamps or earn professional certificates online such as IBM’s Full Stack Cloud Developer.
The SDLC Phases
One big disadvantage here is that it can eat up resources fast if left unchecked. The Agile SDLC model separates the product into cycles and delivers a working product very quickly. Testing of each release feeds back info that’s incorporated into the next version. According to Robert Half, the drawback of this model is that the heavy emphasis on customer interaction can lead the project in the wrong direction in some cases.
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. SDLC provides a number of advantages to development teams that implement it correctly. Developers systems development life cycle process must now move into a maintenance mode and begin practicing any activities required to handle issues reported by end-users. Once complete, development managers will prepare a design document to be referenced throughout the next phases of the SDLC.
What is the software development life cycle (SDLC)?
The agile model is relatively well-known, particularly in the software development industry. Their output may be closer or farther from what the client eventually realizes they desire. It’s mostly used for smaller projects and experimental life cycles designed to inform other projects in the same company. But in theory, it illuminates the shortcomings of the main waterfall model by preventing larger bugs from spiraling out of control.
In other words, the team should determine the feasibility of the project and how they can implement the project successfully with the lowest risk in mind. This article will explain how SDLC works, dive deeper in each of the phases, and provide you with examples to get a better understanding of each phase. When teams have clarity into the work getting done, there’s no telling how much more they can accomplish in the same amount of time.
Advanced methodologies
Application lifecycle management (ALM) is the creation and maintenance of software applications until they are no longer required. It involves multiple processes, tools, and people working together to manage every lifecycle aspect, such as ideation, design and development, testing, production, support, and eventual redundancy. The Development stage involves the actual coding and programming of the system. Based on the design specifications, developers write code, create database structures, and implement necessary functionalities. Rigorous testing and quality assurance are performed to ensure the system’s accuracy, performance, and adherence to the design requirements. Introducing a new clinical information system or component, including electronic health record systems, is a major undertaking for healthcare organizations.
- The final phase of the SDLC is to measure the effectiveness of the system and evaluate potential enhancements.
- In addition, governance and regulations have found their way into technology, and stringent requirements for data integrity impact the team developing technology systems.
- It’s when you gather the team to brainstorm, set goals, and identify risks.
- Below you will find sequential steps to SDLC, but each company will vary in their process.
- Developers will follow any coding guidelines as defined by the organization and utilize different tools such as compilers, debuggers, and interpreters.
System Design is a crucial stage in the SDLC as it bridges the gap between requirements analysis and system development. It transforms user needs and functional specifications into a detailed technical plan that guides the development team. Proper system design ensures that the developed system aligns with the desired functionality, performance, and scalability requirements. In the information systems domain, the terms SDLC and system life cycle are often used interchangeably. It has been suggested that information SDLC should not be confused with system (the delivered product) life cycle.
Organizational project-enabling processes
The system life cycle begins when the SDLC delivers the final product, that is, when the implementation phase begins. The objective of this activity is to extend as long as possible the life cycle of an existing system. When this is not longer feasible or efficient, the system life cycle terminates and a new SDLC commences. Hence, the Agile SDLC model has recently become increasingly popular and in demand.
A configuration management system shall be implemented during development and implementation. The Forensic Laboratory configuration management process is defined in Chapter 7, Section 7.4.5. Each of the testing steps in the development/configuration phase is tested against a step in the design phase. This ensures that the objective of the system is met and that it is fit for purpose. The execution component is responsible for the final deliverable of the project and is built around pure code development, system configuration, or a combination of both. The second theme includes ways to determine the data necessary to produce the logical requirements specified by the organization.

Software developers use this as a guide to ensure software is produced with the lowest cost and highest possible quality in the shortest amount of time. Today, most teams recognize that security is an integral part of the software development lifecycle. You can address security in SDLC following DevSecOps practices and conducting security assessments during the entire SDLC process.
