Objectives:
1. To understand the different processes in the realm of ‘Requirements Engineering’.
2. To see the challenges in requirements development and the importance of getting requirements right in an IT project.
3. To understand the different techniques used in different phases and processes of requirements development and management.
The waterfall model is a sequential (non-iterative) design process, used in software development processes, in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of conception, initiation, analysis, design, construction, testing, production/implementation and maintenance.

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.

This approach carries less risk than a traditional Waterfall approach but is still far more risky and less efficient than a more Agile approaches.
In Iterative model, iterative process starts with a simple implementation of a small set of the software requirements and iteratively enhances the evolving versions until the complete system is implemented and ready to be deployed.

The first formal description of the waterfall model is often cited as a 1970 article by Winston W. Royce
Royce did not use the term "waterfall" in this article.
Royce presented this model as an example of a flawed, non-working model.
Conceived in the 1980s, rapid application development, or RAD, was the first development methodology to challenge traditional waterfall development practices. Though often mistaken for a specific model, rapid application development is the idea that we benefit by treating our software projects like clay, rather than steel.
Software is a unique engineering structure because it is transient. With traditional engineering projects like bridge construction, engineers cannot begin to build a bridge then change their minds half way through the process—that’s pure chaos. But a bridge built in software? Engineers can change that every day. RAD takes advantage of this by emphasizing rapid prototyping over costly planning.

If you watch this one please rate it and do share this presentation to others so then can easily learn more about the Agile Methodology.
Agile management, or agile process management, or simply agile refers to an iterative, incremental method of managing the design and build activities of engineering, information technology and other business areas that aim to provide new product or service development in a highly flexible and interactive manner; an example is its application in Scrum, an original form of agile software development.
What is Agile Methodology?
AGILE methodology is a practice that promotes continuous iteration of development and testing throughout the software development lifecycle of the project. Both development and testing activities are concurrent unlike the Waterfall model
A software process model is an abstraction of the software development process. The models specify the stages and order of a process. So, think of this as a representation of the order of activities of the process and the sequence in which they are performed
This deck gives an overview on the following key areas.
1) Agile Development Principle
2) Scrum Framework
3) User Story Creation
4) Definition of Done
5) Agile – Retrospective
6) Development – Metrics
7) Agile vs Traditional Development Approach
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

PRESENTATION ON AGILE SOFTWARE
DEVELOPMENT LIFE CYCLE

2. • Software Development Life Cycle (SDLC) is a process used by the software industry to
design, develop and test high quality software.
• The SDLC aims to produce a high-quality software that meets or exceeds customer
expectations, reaches completion within times and cost estimates.
• The life cycle defines a methodology for improving the quality of software and the overall
development process.
• It is also called as Software Development Process.
• SDLC is a framework defining tasks performed at each step in the software development
process.
• ISO/IEC 12207 is an international standard for software life-cycle processes.
• It aims to be the standard that defines all the tasks required for developing and
maintaining software.
Software Development Life Cycle
3. • Agile model believes that every project needs to be handled differently and the existing
methods need to be tailored to best suit the project requirements.
• In Agile, the tasks are divided to time boxes (small time frames) to deliver specific
features for a release.
• Iterative approach is taken and working software build is delivered after each iteration.
• Each build is incremental in terms of features and the final build holds all the features
required by the customer.
AGILE MODEL
7. • Our highest priority is to satisfy the customer through early and continuous
delivery of valuable software.
• Welcome changing requirements, even late in development. Agile processes
harness change for the customer’s competitive advantage.
• Deliver working software frequently, from a couple of weeks to a couple of
months, with preference to the shorter timescale.
• Business people and developers must work together daily throughout the
project.
PRINCIPLES OF AGILE MODEL
8. • Build projects around motivated individuals. Give them the environment and
support they need and trust them to get the job done.
• The most efficient and effective method of conveying information to and
within a development team is face-to-face conversation.
• Working software is the primary measure of progress.
• Agile processes promote sustainable development. The sponsors, developers,
and users should be able to maintain a constant pace indefinitely.
9. • Continuous attention to technical excellence and good design enhances agility.
• Simplicity -- the art of maximizing the amount of work not done is essential.
• The best architectures, requirements, and designs emerge from self-organizing
teams.
• At regular intervals, the team reflects on how to become more effective, then
tunes and adjusts its behavior accordingly.
10. • Very realistic approach to software development.
• Promotes teamwork and cross training.
• Functionality can be developed rapidly and demonstrated.
• Resource requirements are minimum.
• Suitable for fixed or changing requirements
• Delivers early partial working solutions.
• Good model for environments that change steadily.
• Minimal rules, documentation easily employed.
• Enables concurrent development and delivery within an overall planned context.
• Little or no planning required.
• Easy to manage.
• Gives flexibility to developers.
ADVANTAGES OF AGILE SDLC
11. • Not suitable for handling complex dependencies.
• More risk of sustainability, maintainability and extensibility.
• An overall plan, an agile leader and agile PM practice is a must without which it will
not work.
• Strict delivery management dictates the scope, functionality to be delivered, and
adjustments to meet the deadlines.
• Depends heavily on customer interaction, so if customer is not clear, team can be
driven in the wrong direction.
• There is a very high individual dependency, since there is minimum documentation
generated.
• Transfer of technology to new team members may be quite challenging due to lack
of documentation.
DISADVANTAGES OF AGILE SDLC
12. • In This case study on Women’s Era (WE- A State Level Women Development and
Support). Specify the differences in the development of a project by using the Agile
Methods: Extreme Programming (XP) and Scrum.
• The purpose of this case study was women from different categories of society from
different areas of Andhra Pradesh. They specified a bulk of requirements which they
are in need regularly like Legal issues, Medical issues, Educational issues, Recipes
and Government schemes. For identifying the sources to get the information they
need to spend a lot of time away from home. So, they searched a number of web
Applications which will be providing the information related to these requirements,
but no application is there to serve for all the needs. For this purpose, they develop
the proposed application to satisfy all these requirements.
Agile Software Development: A Case Study
of Web Application
13. • Customer Interest -In this phase we are concentrating on the requirements of
users called stories, consists of the features and functionalities and these will
be placed on index cards. Customers specify the values for these requirements
called Priorities. Depending on the priorities specified by the customers
releases will be done.
• On priorities basis -The cost and time scheduling must be done again for these.
New story can be written at any time. Grouping of the stories will be done for
the releases. The releases for this case study are totally depending on the
priorities specified by the customer.
On The Analysis Part They Categories
This Phase Into Two Forms.
14. • As per the system Architecture the following are the classes
• In Legal issues Complaint registration, Complaint status.
• In Educational Issues courses In Medical issues Home & Health,.
• In Recipes there are two functionalities Add Recipes and Download.
• In Government schemes we are going to post the information related to
government schemes.
• Internal Acceptance Testing.
• External Acceptance Testing
As per the system Architecture the following
are the classes This Phase Into Two Forms.
15. • Requirements
• Analysis
• Design
• Evolution and Delivery Each framework act.
• Scrum process patterns enable a software development team to work successfully in
a world where the elimination of uncertainty is impossible.
SCRUM incorporates the following
framework activities
16. • In agile development process by using XP methodology, the stories can be
divided in two number of small depending on the time factor (if a story exceeds 3
weeks for the development that can be divided into small stories).
• So in XP the changes can be allowed in the middle of the development. For
example, in this case study if we consider the legal issues, adding of another new
requirement related to complaint like cybercrime will cause some change in the
development which is going to have effect on the size of the story which already
have been specified.
Conclusion
17. • These types of changes can be acceptable in XP. In Scrum once the sprints are
identified and allotted to the team members, they must be stable because they
are frozen. No modifications are allowed until the completion of the
development of that sprint.
• Adding of new sprints in the middle of the development is not possible. In XP
team size should not exceed10 members, and it is limited to 7 in scrum. XP
will not support the distributed development, scrum will support.
