This document discusses different software process models including waterfall, prototyping, incremental development, spiral, RAD, and V-models. It explains the key stages and benefits and limitations of each model. The document emphasizes that each model tries to provide a framework for software development but that borrowing from multiple models may be necessary. Real-life examples like Windows development are given to illustrate using the spiral model.

Agile Requirements Engineering by Abdulkerim CorboBosnia Agile
Requirements engineering (RE) is a defined and systematic approach to the process of finding, documenting, validating and managing requirements in order to deliver successful and customer-oriented software. Specifically, it is an activity of finding the needs and wishes of stakeholders and transforming them into useful data for future use.
This presentation provides answers to the questions: What is RE? Who works on RE? When is RE needed? What are the main activities of RE? Is Agile RE possible?
This presentation provides useful and beneficial information related to software development companies. It defines Software development methodology and elaborates various methodologies adopted by software application development companies, web application development companies, custom software development services in India.

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
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

7. Why have a model
• A model recognize that Software Engineering is more than
just programming
• Recognize product life cycles
– Various requirements specification phases
– Design phases
– Coding and testing phases
– Maintenance phase (bug fixes and revisions)
8. More reasons to have a model
• A model helps recognize and define the division of labor
– Individual responsibilities (program managers, software design
engineers, UI designers, testers, product support,
internationalization, marketing, etc.)
– How big should a team be
– Parallel work efforts
– Does a one person team need a model
• Provide a common means of communication between all
involved parties
• Documentation is vital
– Comments in the code is not sufficient documentation
9. Goals of a good model
• The obvious “Provide a framework for building a solidly
engineered product”
• A paradigm that adds discipline and order to software
development
• Provides a formal mechanism to clarify, track, and modify
the product requirements throughout the product life cycle
• Provide a guideline for engineers to use in the product life
cycle
• Provide feedback into the development cycle
10. More goals of a good model
• Compel engineers to want to use it
– Doesn’t get in the way
– Convinces them that they will build a better product
– Be easy to understand and use
• Keep everyone organized
• Many more “common sense” reasons
13. More on the waterfall model
• What it is
– Each phase is carried out completely (for all requirements) before
proceeding to the next
– The process is strictly sequential - no backing up or repeating
phases
• What it tried to accomplish
– Account for more than programming
– Feedback between phases
– A requirement change can have a major cost downstream
14. More on the waterfall model
• Benefits
– Simple, easy to understand and follow
– Highly structured, therefore good for beginners
– After specification is complete, low customer involvement
required
• Limitations
– Limited feedback increases risk
– Inflexible - can't adapt to changes in requirements
– A requirement change can have a major cost downstream
16. More on prototyping model
• A variation of the waterfall that adds a new phase,
prototyping
• Prototypes intend to reduce risk by building a quick and
dirty replica or mockup of the intended system.
• Demonstrate technical feasibility when the technical risk is
high.
• Used to better understand and elicit user requirements.
• Goal: reduce risk and limit costs by increasing
understanding of proposed solutions before committing
more resources.
18. More on incremental
development
• developing an initial implementation
• exposing this to user feedback
• evolving it through several versions until an
acceptable system has been developed.
19. Incremental Vs Waterfall Model
• cost of accommodating changing
• customer feedback
• rapid delivery
21. More on the spiral model
• What it is
– An iterative approach where multiple passes are made through
each phase
– During each iteration the system is explored at greater depth and
more detail is added
• What it tried to accomplish
– Recognize that Software Engineering is a process of iterative
refinement
– Allow for alternate designs and implementations
22. More on the spiral model
• Benefits
– The iterative natures allows for knowledge gained during early
passes to inform subsequent passes
– Requires low up-front commitment
– Manages uncertainty inherent in exploratory projects
– Strong approval and documentation control
– Additional Functionality can be added at a later date
– Software is produced early in the software life cycle
23. More on the spiral model
• Limitations
– Difficult to establish stable documents
– Things keep getting modified during each iteration
– Too much dependable on Risk Analysis and requires highly
specific expertise
– Spiral may go on indefinitely
– End of the project may not be known early
– May be hard to define objective, verifiable milestones
– Large numbers of intermediate stages require excessive
documentation
24. When to use Spiral model
• When costs and risk evaluation is important
• For medium to high-risk projects
• Users are unsure of their needs
• Requirements are complex
• New product line
• Significant changes are expected (research and
exploration)
25. Real Life Examples of software
using spiral model
• Evolution of Microsoft Windows operating
system
27. Assignments
• RAD model (Odd Roll Numbers)
• V-Model (Even Roll Numbers)
• Instructions:
– Explain its distinction with others
– Benefits & Limitations
– Where to use
– Real life examples
29. Lessons from the models
• Each trying to capture or dictate how a project should be
run
• Even a good properly applied model cannot fix a flawed
design
• Not any model offers the 100% solution
• Often borrowing from one or more model is necessary
• Just as Software Engineering is full of compromises so is
using a Software Engineering model
• So take these models with a grain of salt and use only
those parts that apply to your situation
