Waterfall Model PPT in Software Engineering
What is Waterfall Model? History of waterfall model, Advantages, Disadvantages and much more realted to waterfall model.
The waterfall model is the basic and simple software development life cycle model. But idealistic. Earlier the waterfall model was very popular but these days it is not used while software development. And the model was divided into phases and all the phases are organized in linear order. This model was first introduced by Dr. Winston in 1970.
This model is very popular and very important because all the models in software development life cycle models are based on it. So, we can call it, It is the base of all software development life cycle models or it is known as Classical Waterfall Model.
Feature driven development (FDD)
FDD is a software development process that is client-centric, architecture-centric, and pragmatic. It focuses on developing features, which are small client-valued functions. Key aspects of FDD include developing an overall model, building a prioritized feature list, planning by feature, designing by feature, and building by feature in an iterative process. FDD was created by Jeff DeLuca in 1997 for a banking project and combines techniques like modeling, domain-driven design, and agile practices like XP.
Software Engineering Process Models
The document discusses various aspects of the software process including software process models, generic process models like waterfall model and evolutionary development, process iteration, and system requirements specification. It provides details on each topic with definitions, characteristics, advantages and diagrams. The key steps in software process are specified as software specifications, design and implementation, validation, and evolution. Generic process models and specific models like waterfall, evolutionary development, and incremental delivery are explained.
Unified process Model
The Unified Process (UP) is a software development process that provides guidance on team activities and work integration. It originated from issues with traditional processes being too diverse and outdated. Key aspects of UP include being use-case driven, architecture-centric, and iterative/incremental. UP follows a lifecycle of inception, elaboration, construction, and transition phases within iterative development cycles. While UP addressed issues with prior methods, its weaknesses include not covering the full software process and tools-focus not suiting complex systems.

A Water Fall Model is easy to flow.
It can be implemented for any size of project.
Every stage has to be done separately at the right time so you cannot jump stages.
Documentation is produced at every stage of a waterfall model allowing people to understand what has been done.
Testing is done at every stage.
This model was not the first model to discuss iterative development.
As originally envisioned, the iterations were typically 6 months to 2 years long.
Each phase starts with a design goal and ends with the client (who may be internal) reviewing the progress thus far.
Analysis and engineering efforts are applied at each phase of the project, with an eye toward the end goal of the project.

Agile software development and extreme Programming
This document discusses Agile development and eXtreme Programming (XP). It describes XP as an Agile methodology that focuses on frequent delivery of working software through practices like test-driven development, pair programming, and continuous integration. The document outlines the 12 key practices of XP like planning games, simple design, refactoring, and on-site customers. It notes advantages of XP like increased customer focus and quality, and disadvantages like potential issues with certain team members or inflexible requirements.
Software development life cycle (SDLC)
The document defines the software development life cycle (SDLC) and its phases. It discusses several SDLC models including waterfall, prototype, iterative enhancement, and spiral. The waterfall model follows sequential phases from requirements to maintenance with no overlap. The prototype model involves building prototypes for user feedback. The iterative enhancement model develops software incrementally. The spiral model is divided into risk analysis, engineering, construction, and evaluation cycles. The document also covers software requirements, elicitation through interviews and use cases, analysis through data, behavioral and functional modeling, and documentation in a software requirements specification.
Software process
The software process involves specification, design and implementation, validation, and evolution activities. It can be modeled using plan-driven approaches like the waterfall model or agile approaches. The waterfall model involves separate sequential phases while incremental development interleaves activities. Reuse-oriented processes focus on assembling systems from existing components. Real processes combine elements of different models. Specification defines system requirements through requirements engineering. Design translates requirements into a software structure and implementation creates an executable program. Validation verifies the system meets requirements through testing. Evolution maintains and changes the system in response to changing needs.
Agile Software Development Overview
The document introduces agile software development methods. It discusses the goals of being able to speak confidently about agile and provide solutions to problems teams face. The agenda covers introductions to agile principles, roles, planning, reporting, retrospectives, and estimating. Popular agile methods like Scrum and XP are explained. The roles of product managers and product owners are compared.
Software Process Models
The document discusses various software process models including prescriptive models like waterfall model and incremental process model. It also covers evolutionary models like prototyping and spiral process model. Specialized models covered are component based development, formal methods model, aspect oriented development and unified process model. The key highlights are that different models are suited for different situations based on project needs and each model has advantages and disadvantages to consider.
Software Development Life Cycle-SDLC
The document discusses the software development life cycle (SDLC) process. It includes 6 main steps: 1) requirement gathering, 2) software analysis, 3) software design, 4) coding, 5) testing, and 6) implementation. For each step, the document provides details on the objectives and activities involved. It also lists advantages of following the SDLC process such as increased quality, improved tracking, and decreased risks. Finally, it provides a coding example for a basic calculator application to illustrate one step of the process.
Requirements engineering for agile methods
In systems engineering and software engineering, requirements analysis encompasses those tasks that go into determining the needs or conditions to meet for a new or altered product or project, taking account of the possibly conflicting requirements of the various stakeholders, analyzing, documenting, validating and managing software or system requirements.
The Software Development Process
The document discusses the software development process and defines key terms. It states that a software process organizes development activities and includes roles, workflows, procedures and standards. Following a defined process makes software development more orderly, predictable and repeatable. However, some view following a process as unnecessary overhead. The reality is that not following a process can lead to more rework that outweighs any initial time savings. The document also discusses software life cycle models, such as waterfall and iterative models, and how a good process is repeatable, predictable, adaptable, learnable and measurable.
Spiral model of SDLC
The document describes the spiral model of the software development life cycle (SDLC). It discusses the phases of the spiral model including planning, risk analysis, engineering, and evaluation. The spiral model is an iterative approach that combines elements of both design and prototyping-based development. It allows for incremental adjustments to requirements through repeated cycles. The model helps manage risk on large, complex projects that experience changing requirements over time.
Software Development Process
The document provides an overview of various software development processes and models, including traditional waterfall and iterative models as well as agile methods like Scrum and Extreme Programming (XP). It discusses key aspects of each approach such as phases, roles, meetings, practices, and values. The document aims to introduce different process options and considerations for developing software.
Software Engg. process models
This document outlines and compares five software development models: waterfall, iterative, V-shaped, spiral, and extreme programming. Each model is described in terms of its phases or activities, advantages, and disadvantages. The waterfall model involves sequential non-overlapping phases from requirements to maintenance. Iterative development divides a project into smaller parts with feedback between phases. The V-shaped model emphasizes testing at each stage. The spiral model performs risk analysis and prototypes in iterative loops. Extreme programming focuses on small incremental releases and pair programming. In conclusion, the author states that different models suit different projects and each tries to improve on previous limitations.
The Waterfall Model
The document describes the Waterfall Model of software development. It consists of sequential phases: requirements, design, implementation, testing, and deployment. While easy to understand, it has disadvantages like inability to change requirements later in the process and lack of early working software. The document also discusses improving the model by adding design phases, documentation, testing planning, and customer involvement.
PRESCRIPTIVE PROCESS MODEL(SOFTWARE ENGINEERING)
A prescriptive process model is a model that describes "how to do" according to a certain software process system. ... Prescriptive models are used as guidelines or frameworks to organize and structure how software development activities should be performed, and in what order.
Prototyping model advantages and disadvantages
The prototype model involves building a throwaway prototype early in the development process to help understand requirements rather than freezing them upfront. This allows clients to get hands-on experience with the system and provide better feedback. Prototypes are incomplete but provide overall functionality. The prototype model is best for complex systems where requirements are unclear and user interaction and feedback is important, such as web and online systems. It enables errors and missing requirements to be identified early. However, it risks requirements changing too much and the system becoming more complex than originally intended.
Iterative model
The iterative model breaks a project into small modules that can be delivered incrementally. A working version is produced in the first module, with each subsequent release adding additional functionality until the full system is complete. It allows for quick releases during development and makes it easier to develop and test in smaller iterations while incorporating customer feedback at each stage. However, it requires more resources than traditional models and skilled management to avoid increased costs over time.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

FOCUS GROUP meeting Customers and developers meet to review product together, refine requirements, generate change requests. Developers listen. Customers talk. Requirements and change requests are "time boxed". Changes that cannot be accommodated within existing time boxes are eliminated. If necessary to stay "in the box," secondary requirements are dropped.
- 9. • Iterative and Incremental development is at the heart of a cyclic software development process developed in response to the weaknesses of the waterfall model.
- 10. This type of lifecycle is a risk mitigation driven process. Technical risks are assessed and prioritized early in the lifecycle and are revised during the development of each iteration. Risks are attached to each iteration so that successful completion of the iteration mitigates the risks attached to it. The releases are scheduled to ensure that the highest risks are tackled first

Validation problems Without a specification, what is the system being tested against? Maintenance problems Continual change tends to corrupt software structure making it more expensive to change and evolve to meet new requirements. Because during the development process needs to be adapted and refined, it may be that the original purpose fades. It can happen that it continues to change and it never finished. This is called Scope Creep. Project managers who are accustomed to linear development can be confused by the strong dynamics.(-may be problems because of the lack of understand about The rapid development has the potential to draw a bill on the organization and resources of the great dynamics.
