Rapid Application Development (RAD) is an agile software development methodology that emphasizes iterative development, user involvement, and rapid prototyping. It comprises four main phases: requirements planning, user design, construction, and cutover. RAD aims to significantly reduce development time compared to traditional models by encouraging continuous user feedback and integration from the beginning. However, it also requires highly skilled developers and designers as well as strong modeling capabilities.
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.

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.
These PPT presentation help to understand waterfall model in SDLC. The Waterfall model is the earliest SDLC approach that was used for software development. There are five steps in the waterfall model.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

RAD
• Rapid Application Development is a lightweight
approach to development. It is divided into four
phases:
– 1. Requirements Planning Phase
– 2. User Design Phase
– 3. Construction Phase
– 4. Cutover Phase
15. 15
RAD
• 1. Requirements Planning Phase
– Also called “Joint Requirements Planning (JRP) Phase”
– Combines the Planning and Analysis phases from the
Waterfall Model
– End-users and IT staff agree on business needs, project
scope, constraints, and system requirements
– This phase ends when the team agree on the key issues
and obtain management authorization to continue
16. 16
RAD
• 2. User Design Phase
– End-users and IT staff jointly develop the system
processes, inputs, and outputs.
– They use a combination of Joint Application Design (JAD)
and CASE tools.
– This needs to be a continuous interactive process that
allows End-users to understand, modify, and eventually
approve a working model of the system that meets their
needs.
17. 17
RAD
• 3. Construction Phase
– Similar to the Development phase in the Waterfall model,
but End-users continue to participate and can still suggest
changes or improvements as actual screens or reports are
developed.
– The key tasks in this phase are programming and
application development, coding, unit-integration and
system testing.
18. 18
RAD
• 4. Cutover Phase
– Similar to the Installation, Testing and Maintenance phases
of the Waterfall model, including data conversion, testing,
changeover to the new system, and user training.
– Compared with traditional methods, the entire process is
compressed, and as a result, the new system is built,
delivered, and placed in operation much sooner
20. 20
RAD
• Tools
– Using CASE tools provides automation support for systems
development through features such as code generation
and automatic consistency checking.
– CASE tools that generate prototypes can be used to
support the iterative development approach, allowing end
users to see the application evolve as it is being built.
21. 21
RAD
• Methodology
– The most effective family of techniques must be
formalised and used to deliver the system.
– A complete list of tasks is provided to ensure that no
essential activity is overlooked, while techniques are fully
documented to ensure that a task is performed in the
proper way.
22. 22
RAD
• People
– The best people must be well-trained in both the
methodology and the tools.
– Small teams that work consistently well together should be
grouped together on assignments.
23. 23
RAD
• Management
– The project must be managed for speed through the use of
techniques such as facilitated Joint Requirements Planning
(JRP) and Joint Application Design (JAD) workshops to
extract users' requirements quickly.
– Timebox Management is used in Rapid Construction to
iteratively deliver the system to the users.
39. 39
Interesting
• RAD should be used when there is a need to create a
system that can be modularized in 2-3 months of
time.
40. 40
Interesting
• RAD should only be used be used:
– if there’s high availability of designers for
modelling
– if the budget is high enough to afford their cost
along with the cost of automated code generating
tools.
– if resources with high business knowledge are
available and there is a need to produce the
system in a short span of time (2-3 months).
