Report on SOFTWARE DEVELOPMENT LIFE CYCLE SDLC Neetu Marwah
The document discusses the software development life cycle (SDLC). It describes SDLC as a process used in software engineering to break down development into distinct phases to better plan and manage projects. The phases include requirements study, design, development, testing, and maintenance. The document outlines each phase in detail and notes the key documents produced and activities involved at each stage of the SDLC process.
The systems development life cycle (SDLC) describes the process of planning, creating, testing, and deploying an information system. It involves several key phases: preliminary analysis, requirements definition, design, development, integration and testing, deployment, maintenance, and disposal. Each phase serves an important purpose in properly analyzing requirements, designing the system, developing and testing code, deploying the final product, and maintaining or replacing the system. Testing occurs at various stages to ensure quality and identify issues. The SDLC process helps information systems meet goals on time and on budget.
The document discusses SDLC (Systems Development Life Cycle) and e-business. It begins by defining key terms like system, information system, and problem identification. It then explains various phases of SDLC like planning, analysis, design, implementation, testing and maintenance. It also discusses different SDLC models like waterfall, iterative and agile. The document also covers topics like requirements analysis, feasibility study, design and testing. Finally, it provides definitions of business, commerce and e-business and discusses how ICT technologies help in integrating business processes and enabling e-business.
Here are the answers to the questions:
1. Implementation is generally considered the most expensive stage of software development. It requires the most resources like programmers, testers etc.
2. Most errors are introduced in the requirements and design phases where misunderstandings between users and developers are common.
3. Project managers say that scope creep and changing requirements are the worst problems in software projects as they lead to cost overruns and missed deadlines.
The document discusses different systems development life cycles (SDLC) including the traditional SDLC model and alternatives like prototyping, Rapid Application Development (RAD), and Joint Application Development (JAD). The traditional SDLC model involves phases like requirements definition, feasibility study, systems analysis, systems design, implementation, and maintenance. However, it has some limitations that newer approaches aim to address, focusing more on user involvement, flexibility, and rapid iterations.

In the realm of software and systems engineering, the System Design Life Cycle (SDLC) stands as a critical framework for ensuring that complex systems are developed in a structured and efficient manner. This comprehensive guide delves into the intricate stages of the SDLC, providing a detailed overview that caters to both novices and experienced professionals seeking to enhance their understanding of system design and implementation.
The SDLC is a multi-phase process, typically encompassing the following stages: Planning, Analysis, Design, Implementation, Testing, Deployment, and Maintenance. Each phase is crucial in its own right, contributing to the overall success and sustainability of the system. This guide breaks down each stage, highlighting key activities, objectives, and best practices.
1. Planning
The planning phase is the cornerstone of the SDLC. It involves identifying the scope and objectives of the project, conducting feasibility studies, and assembling the project team. This stage sets the groundwork for all subsequent phases, ensuring that the project aligns with business goals and stakeholder expectations. Effective planning requires meticulous attention to detail, risk assessment, and resource allocation.
2. Analysis
During the analysis phase, detailed requirements gathering and analysis are conducted. This involves engaging with stakeholders to understand their needs and expectations, and documenting functional and non-functional requirements. Techniques such as interviews, surveys, and use case analysis are employed to ensure a comprehensive understanding of what the system must achieve. The outcome of this phase is a clear and detailed requirements specification document.
3. Design
The design phase translates requirements into a blueprint for the system. This involves architectural design, which outlines the overall structure and components of the system, and detailed design, which specifies the internal workings of each component. Key considerations during this phase include system architecture, data flow diagrams, interface design, and technology selection. The goal is to create a robust and scalable design that meets the specified requirements.
4. Implementation
Implementation, or development, is where the actual coding and construction of the system take place. Using the design documents as a guide, developers write code, create databases, and integrate various system components. Adhering to coding standards, version control practices, and continuous integration are critical for maintaining code quality and ensuring that the system functions as intended.
5. Testing
Testing is a pivotal phase that ensures the system meets all specified requirements and is free of defects. This phase involves various levels of testing, including unit testing, integration testing, system testing, and user acceptance testing. The objective is to identify and rectify any issues before the system is deployed.
Overview Of System Development Life Cycle (SDLC)Nicole Savoie
The document discusses the system development life cycle (SDLC), which is a process used for developing systems from planning through implementation. It contains four main steps: analysis, planning, design, and implementation. During analysis, data flow diagrams are used to model the system's processes. Consistency between context and lower-level data flow diagrams is important for an easy-to-follow process model. SDLC is also used to determine how an information system can support business needs by designing, building, and delivering the system to users through the analysis, design, implementation, and testing phases. Procedure models created during analysis help define requirements graphically. Reliability of the process model is key to improving later SDLC stages.

It describes the purpose and history of SDLC as emerging in the 1960s to address the "software crisis". It also outlines the main steps and activities in each phase of the SDLC process.
The document discusses the system development life cycle (SDLC), which involves 6 main steps: 1) preliminary investigation, 2) requirements analysis, 3) system design, 4) system acquisition and development, 5) system testing, and 6) implementation and maintenance. It describes each step in detail, including gathering user requirements, designing and selecting a software model, testing the system, training users, and evaluating the results. The SDLC aims to efficiently develop high-quality software through a structured process of analysis, design, implementation, and maintenance activities.
The document discusses several approaches to system development including the waterfall model, prototyping model, incremental model, and spiral model. The waterfall model involves sequential phases from requirements analysis to maintenance. The prototyping model develops initial prototypes to refine user requirements, while the incremental model delivers software in iterations. The spiral model combines elements of waterfall and prototyping, with risk analysis and evaluation at each phase.
Software testing and introduction to qualityDhanashriAmbre
The document provides an overview of software testing and quality assurance. It defines software testing as a process to investigate quality and find defects between expected and actual results. Testing is necessary to ensure software is defect-free per customer specifications and increases reliability. The document then discusses types of errors like ambiguous specifications, misunderstood specifications, and logic/coding errors. It outlines the software development life cycle including phases like planning, analysis, design, coding, testing, implementation, and maintenance. Each phase is described in 1-2 sentences.
The document provides an overview of the Software Development Life Cycle (SDLC), which is a process used to develop software in a logical, structured manner. It consists of six phases - system planning, system analysis, system design, system coding, system testing, and deployment and maintenance. The goal of the SDLC is to produce high-quality software that meets customer expectations with the highest quality, lowest cost, and shortest time. Each phase results in deliverables for the next phase and aims to gradually develop the system from inception of an idea through implementation and delivery.
The document discusses the software development life cycle (SDLC) which includes 8 phases: system conception, requirement gathering, system design, class design, implementation, testing, deployment, and maintenance. It states that requirement gathering focuses on what must be done without how, and involves domain and application analysis. Domain analysis emphasizes real-world objects to understand the problem domain. The implementation phase is the longest as it involves coding the requirements.
This document discusses the software development life cycle (SDLC) model. It defines the SDLC as a detailed plan for creating, developing, implementing, and eventually retiring software. The SDLC involves phases such as concept development, planning, requirements analysis, design, development, testing, implementation, and maintenance. Two common SDLC models are the waterfall model and iterative model. Following an SDLC is important for health IT systems to ensure software meets needs, integrates properly, and has appropriate documentation for maintenance.

Information System Acquisition & Lifecycle: system acquisition process, phases: Initiation, Planning, Procurement, System Development, System Implementation, Maintenance & Operations, and Closeout. development models.
In the realm of software and systems engineering, the System Design Life Cycle (SDLC) stands as a critical framework for ensuring that complex systems are developed in a structured and efficient manner. This comprehensive guide delves into the intricate stages of the SDLC, providing a detailed overview that caters to both novices and experienced professionals seeking to enhance their understanding of system design and implementation.
The SDLC is a multi-phase process, typically encompassing the following stages: Planning, Analysis, Design, Implementation, Testing, Deployment, and Maintenance. Each phase is crucial in its own right, contributing to the overall success and sustainability of the system. This guide breaks down each stage, highlighting key activities, objectives, and best practices.
1. Planning
The planning phase is the cornerstone of the SDLC. It involves identifying the scope and objectives of the project, conducting feasibility studies, and assembling the project team. This stage sets the groundwork for all subsequent phases, ensuring that the project aligns with business goals and stakeholder expectations. Effective planning requires meticulous attention to detail, risk assessment, and resource allocation.
2. Analysis
During the analysis phase, detailed requirements gathering and analysis are conducted. This involves engaging with stakeholders to understand their needs and expectations, and documenting functional and non-functional requirements. Techniques such as interviews, surveys, and use case analysis are employed to ensure a comprehensive understanding of what the system must achieve. The outcome of this phase is a clear and detailed requirements specification document.
3. Design
The design phase translates requirements into a blueprint for the system. This involves architectural design, which outlines the overall structure and components of the system, and detailed design, which specifies the internal workings of each component. Key considerations during this phase include system architecture, data flow diagrams, interface design, and technology selection. The goal is to create a robust and scalable design that meets the specified requirements.
4. Implementation
Implementation, or development, is where the actual coding and construction of the system take place. Using the design documents as a guide, developers write code, create databases, and integrate various system components. Adhering to coding standards, version control practices, and continuous integration are critical for maintaining code quality and ensuring that the system functions as intended.
5. Testing
Testing is a pivotal phase that ensures the system meets all specified requirements and is free of defects. This phase involves various levels of testing, including unit testing, integration testing, system testing, and user acceptance testing. The objective is to identify and rectify any issues before the system is deployed.
Overview Of System Development Life Cycle (SDLC)Nicole Savoie
The document discusses the system development life cycle (SDLC), which is a process used for developing systems from planning through implementation. It contains four main steps: analysis, planning, design, and implementation. During analysis, data flow diagrams are used to model the system's processes. Consistency between context and lower-level data flow diagrams is important for an easy-to-follow process model. SDLC is also used to determine how an information system can support business needs by designing, building, and delivering the system to users through the analysis, design, implementation, and testing phases. Procedure models created during analysis help define requirements graphically. Reliability of the process model is key to improving later SDLC stages.
SDLC Apresentação - Shift Education of TechnologyRaphaff
The document discusses the software development lifecycle (SDLC) process. It describes the traditional five phases of the SDLC and how it has evolved to seven phases. Each phase is explained in detail, including planning, analysis, design, development, integration and testing, implementation, and operations and maintenance. Different SDLC models like waterfall, iterative, and agile are also summarized. The agile manifesto and scrum framework are introduced as part of the agile methodology. Key terms related to SDLC documentation are defined in a glossary.
The document discusses the system development life cycle (SDLC), which includes preliminary investigation, requirements analysis, system design, software development, system testing, and implementation and maintenance. It describes the purpose and history of SDLC as emerging in the 1960s to address the "software crisis". It also outlines the main steps and activities in each phase of the SDLC process.
The document discusses the system development life cycle (SDLC), which involves 6 main steps: 1) preliminary investigation, 2) requirements analysis, 3) system design, 4) system acquisition and development, 5) system testing, and 6) implementation and maintenance. It describes each step in detail, including gathering user requirements, designing and selecting a software model, testing the system, training users, and evaluating the results. The SDLC aims to efficiently develop high-quality software through a structured process of analysis, design, implementation, and maintenance activities.
The document discusses several approaches to system development including the waterfall model, prototyping model, incremental model, and spiral model. The waterfall model involves sequential phases from requirements analysis to maintenance. The prototyping model develops initial prototypes to refine user requirements, while the incremental model delivers software in iterations. The spiral model combines elements of waterfall and prototyping, with risk analysis and evaluation at each phase.

1. System Development Life Cycle
(SDLC)
Kavindu Chethiya Yakupitiya
BSc (Hons) IT [KDU] , PGD In Cyber Security [SLIIT] , MSc (Hons) in Cyber Security - Reading [SLIIT]
2. What is a SDLC?
❑ The systems development life cycle (SDLC) is the process of
determining how an information system (IS) can support business
needs, designing the system, building it, and delivering it to users.
• The key person in the SDLC is the systems analyst, who analyzes the business
situation, identifies the opportunities for improvements, and designs an IS to
implement the improvements.
• It is also called as Software Development Process.
4. Overview of SDLC.
The SDLC is composed of Six fundamental phases:
• Planning
• Analysis
• Design
• Development/Implementation
• Testing & Integration
• Maintenance.
❑Each of the phases is composed of steps, which rely on techniques that produce
deliverables (specific documents that explain various elements of the system).
5. Step 01 – Planning.
▪ Planning address main two questions?
✓Why?
✓How?
• This phase is the fundamental process of understanding why an information
system should be built, and determining how the project team will go about
building it.
• This is the phase where Business analyst gather all the requirements in order to
build the system. (Requirement Gathering)
• The new system requirements are defined. In particular, the deficiencies in the
existing system must be addressed with specific proposals for improvement.
Other factors defined include needed features, functions and capabilities.
6. Step 02 – Analysis.
• Analysis address four main questions?
✓Who?
✓What?
✓Where?
✓When?
• The analysis phase answers the questions of who will use the system, what the
system will do, and where and when it will be used.
• During this phase the project team investigates any current system(s), identifies
improvement opportunities, and develops a concept for the new system.
7. Step 03 – Design.
• Design phase address one main question?
✓How
• The design phase decides how the system will operate, in terms of the
hardware, software, and network infrastructure; the user interface,
forms, and reports that will be used; and the specific programs,
diagrams, databases, and files that will be needed.
8. Step 04 – Development/Implementation.
• During the implementation phase, the system is either developed or
purchased (in the case of packaged software) and installed.
• This phase is usually the longest and most expensive part of the process.
• The new system is developed. The new components and programs must
be obtained and installed. Users of the system must be trained in its use.
9. Step 05 – Testing & Integration.
• System Integration Testing is defined as a type of software
testing carried out in an integrated hardware and software environment
to verify the behavior of the complete system.
• It also verifies a software system's coexistence with others and tests the
interface between modules of the software application.
• This is the stage where we check our final output/final system is working
error free and developed according to the given requirements.
10. Step 06 – Maintenance.
• The maintenance phase of the SDLC occurs after the product is in full
operation. Maintenance of software can include software upgrades,
repairs, and fixes of the software if it breaks.
• During the maintenance phase, errors or defects may exist, which would
require repairs during additional testing of the software.
11. Advantages of SDLC.
• Gives a defined view of the entire system, resources, timeline, and goals
• Design reviews help to ensure the reliability and quality of the final
product
• Enhanced control over large or complex projects
• Involves comprehensive and explicit steps
• Provide goals and deliverables that meet the standards of each party
involved in the project, requires keeping detailed documentation
throughout the entire process
• Easy evaluation of costs and growth of the developed system
12. Methodologies of SDLC (Types).
• There are only 2 types in SDLC Methodologies.
1. Traditional Methodology.
- Waterfall Model
- Prototyping Model
- Spiral Model
- V Model
- Rapid Application Development
2. Agile Methodology.
- Kanban.
- Scrum.
- Extreme Programming (XP)
- Dynamic Systems Development Method (DSDM)
- Lean Development Method
