Software Development Life Cycle SDLC: Definition, Benefits

It then creates the software through the stages of analysis, planning, design, development, testing, and deployment. By anticipating costly mistakes like failing to ask the end-user or client for feedback, SLDC can eliminate redundant rework and after-the-fact fixes. Quality assurance is of crucial importance in software development projects. Running tests helps companies to carry out a thorough evaluation of the way the software functions and its important features. Thanks to this evaluation, it is possible to make estimations, if the product meets all the customer desires and pre-set goals. After detailed testing, the conclusive product is released in phases as per the organization’s strategy.

Additionally, the tools can provide for configuration management and error checking in the design and code generation. Powerful tools, when used properly to create a complete design, can generate thousands of lines of code, often creating gains in productivity. However, it is also common for the generated code to require alteration before it can operate properly. Some programmers feel it is easier to code a system by hand than to debug and recode soft ware generated by a case tool. Several architectural conformance approaches exist in the literature (Murphy et al., 2001; Ali et al.; Koschke and Simon, 2003). These check whether software conform to the architectural specifications (or models).

Software Design

The SDLC is a framework for assessing and improving development processes. As processing power grows, the demand for software and developers grows as well. These processes deal with planning, assessment, and control of software and other projects during the life cycle, ensuring quality along the way. In the spiral development model, the development process is driven by the unique risk patterns of a project. The development team evaluates the project and determines which elements of the other process models to incorporate.

To perform these activities, strong collaborative relationships between various teams are mandatory during the whole development life cycle. Business development specialists, marketers, programmers, and other professionals from specific spheres work together with this aim. In conclusion, we now know that Software Development Life Cycle (SDLC) software engineering is an important framework for the better and more structured development of optimized software programs.


The scope of this document is the same as ISO/IEC/IEEE 15288, which addresses more than systems engineering activities. This document provides general guidance for each ISO/IEC/IEEE process and process outcome in the context of SoS, but it does not address specific activities, tasks, methods, or procedures. Additional processes and process outcomes unique to SoS can still be needed and are not covered by this document.

The developers should thoroughly follow this document and also should be reviewed by the customer for future reference. Once the required function is done, an analysis is complete with auditing the feasibility of the growth of a product. Baselines[clarification needed] are established after four of the five phases of the SDLC, and are critical to the iterative nature of the model.[21] Baselines become milestones.

They continuously evaluate requirements, plans, and results so that they can respond quickly to change. The agile model is both iterative and incremental, making it more efficient than other process models. The development team combines automation and manual testing to check the software for bugs.

The deliverable from the engineering organization is frequently in the form of a golden master media used for duplication or to produce the image for the web. The term release to manufacturing (RTM), also known as “going gold”, is a term used when a software product is ready to be delivered. This build may be digitally signed, allowing the end user to verify the integrity and authenticity of the software purchase. A copy of the RTM build known as the “gold master” or GM[13] is sent for mass duplication or disc replication if applicable. The terminology is taken from the audio record-making industry, specifically the process of mastering. RTM precedes general availability (GA) when the product is released to the public.

Life cycle

Architectural Styles or Patterns describe the structure and interaction between collections of components affecting positively to a set of quality attributes but also negatively to others. For example, ADD and ATAM follow a recursive process based on quality attributes that a system needs to fulfill. At each stage, tactics and architectural patterns (or styles) are chosen to satisfy some qualities. A software life cycle model describes entry and exit criteria for each phase. So without a software life cycle model, the entry and exit criteria for a stage cannot be recognized. Without software life cycle models, it becomes tough for software project managers to monitor the progress of the project.

Planning is a crucial step in everything, just as in software development. In this same stage, requirement analysis is also performed by the developers of the organization. This is attained from customer inputs, and sales department/market surveys. Each function should be thoroughly checked to ensure that it functions correctly.

Stage 3: Designing the Product Architecture

It works perfectly with any application, regardless of framework, and has plugins. Atatus is a Full Stack Observability Platform that lets you review problems as if they happened in your application. Instead of guessing why errors happen or asking users for screenshots and log dumps, Atatus lets you replay the session to quickly understand what went wrong. This might be as simple as a payment portal and download link on the company’s website. Companies must cut costs, deploy software more quickly, and meet or exceed the expectations of their customers. SDLC helps in the achievement of these objectives by detecting inefficiencies and increased costs and resolving them so that everything runs smoothly.

software life cycle definition

ISO/IEC/IEEE provides unified and consolidated guidance on the life cycle management of systems and software. The software development lifecycle (SDLC) is the cost-effective and time-efficient process that development teams use to design and build high-quality software. The goal of SDLC is to minimize project risks through forward planning so software life cycle definition that software meets customer expectations during production and beyond. This methodology outlines a series of steps that divide the software development process into tasks you can assign, complete, and measure. The software development life cycle (SDLC) is a structured process that is used to design, develop, and test good-quality software.

Stage-2: Defining Requirements

During a sprint, user stories are taken off the product backlog according to the priority of the item and implemented by the team [19]. The goal of Scrum is to create a potentially shippable increment with every sprint, which is a new release of the system that can be presented to the business user and potentially put into production [20] (Figure 3.7). Towards solving this issue Bachmann et al. (2003), Babar et al. (2004) describe steps for deriving architectural tactics. However, this requires that architects need to be familiar with formal specifications that are specific to quality models. It has also been reported by Koschke and Simon (2003) that some quality attributes do not have a reasoning framework.

  • Software development is a huge undertaking and requires thorough planning, regardless of the model.
  • The answer lies in thorough planning each step of the software development life cycle.
  • However, no matter how complex the software is, it needs to be flexible, easy to maintain, and enhance.
  • This International Standard also establishes definitions for the various types of maintenance.
  • These requirements get approval from customers, market analysts, and stakeholders.
  • The many stages of system development in the domains of software engineering, system engineering, and information systems are referred to as the software development life cycle (SDLC).
