4 Phases of the Project Management Lifecycle Explained
Phase 4 represents the real beginning of software production and hardware installation (if necessary). 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.
In the fifth phase, systems integration and testing are carried out by Quality Assurance (QA) professionals. They will be responsible for determining if the proposed design reaches the initial business goals set by the company. It’s possible for testing to be repeated, specifically to check for bugs, interoperability, and errors. The second SDLC phase is where teams will work on the root of their problem or need for a change.
System Development Life Cycle:
The Agile model prioritizes collaboration and the implementation of small changes based on regular feedback. The Agile model accounts for shifting project requirements, which may become apparent over the course of SDLC. This process involves detecting the possible bugs, defects, and errors, searching for vulnerabilities, etc., and can sometimes take up even more time compared to the app-building stage.
Phase 6 of the initial development state of the systems development life cycle puts the software into production and runs as needed. If it performs the tasks correctly and represents the system, the developer moves on to the next phase of maintenance within the system development stages of system development life cycle life cycle. The systems development life cycle (SDLC, also called the software development life cycle or simply the system life cycle) is a system development model. SDLC is used across the IT industry, but SDLC focuses on security when used in context of the exam.
If the initiation phase is assembling your troops, the planning phase is deciding what to do with them. The project management lifecycle is a step-by-step framework of best practices used to shepherd a project from its beginning to its end. It provides project managers a structured way to create, execute, and finish a project. One is a reliable methodology; second is a detailed process from getting from point A to point B. Are you getting your feet wet in the extensive world of software development for the first time?
- The team produces a new software version at the end of each iteration.
- This ensures that the objective of the system is met and that it is fit for purpose.
- It is important to dispose of system information discreetly and securely, as much of the information can be of a personal nature.
- Phase 3 of the systems development life cycle describes the desired features and operations of the system.

It is important that you have contingencies in place when the product is first released to market should any unforeseen issues arise. Microservices architecture, for example, makes it easy to toggle features on and off. A canary release (to a limited number of users) may be utilized if necessary. This method results in several release cycles, during which each iteration is tested, bugs are resolved, and input from stakeholders is gathered.
Stage 5: Implement
Often the systems to be designed are based on software or IT infrastructure. This means that the systems development designers will likely be IT specialists or software developers. This phase often requires extensive programming skills and knowledge of databases.
From then on, suppose the team representative is allowed the freedom to develop the roles assigned to them in whatever way they like. The systems development life cycle originally consisted of five stages instead of seven. These included planning, creating, developing, testing, and deploying.
Extreme Programming (XP) explained
After completion of maintenance period, the contract may be extended depend on mutual agreement between both parties. The maintenance phase ensure that the system is functional, improving the software/hardware, and updating the system. Software developers will monitor the overall system and add the latest security technologies to protect from cyber security threats. Another key reason why teams need to leverage an SDLC is, it’s important that they plan ahead of time and examine the structured goals and stages of a specific project.
Structured Analysis and Design Technique (SADT) – helps people describe and understand systems through a diagrammatic notation. SADT can be used as a functional analysis tool of a given process, using successive levels of detail. Requirements Gathering – provides alternative means to illustrate, explain, and specify exactly what must be delivered to meet business goals. Describe the stages involved in the System Development Life Cycle (SDLC) and their significance in system design.
I.A.2. Systems Development Life Cycle
DevSecOps, an extension of DevOps, is a methodology that emphasizes the integration of security assessments throughout the entire SDLC. It ensures that the software is secure from initial design to final delivery and can withstand any potential threat. However, unlike traditional software development that addresses security as a separate stage, SDLC addresses security every step of the way through DevSecOps practices.
Application performance monitoring (APM) tools can be used in a development, QA, and production environment. This keeps everyone using the same toolset across the entire development lifecycle. At this stage, the goal is to deploy the software to the production environment so users can start using the product. However, many organizations choose to move the product through different deployment environments such as a testing or staging environment. Popular SDLC models include the waterfall model, spiral model, and Agile model. Security is critical – especially when the purpose of the system development life cycle is to create software.
Systems development life cycle: The different stages
This makes it possible for developers to find and fix flaws at the most cost-efficient point in the development process and deliver more secure software, faster. In order to understand the concept of system development life cycle, we must first define a system. A system is any information technology component – hardware, software, or a combination of the two.
