Chapter 10 - http://www.slideshare.net/jcabot/mdse-bookslideschapter10managingmodels
This book discusses how approaches based on modeling can improve the daily practice of software professionals. This is known as Model-Driven Software Engineering (MDSE) or, simply, Model-Driven Engineering (MDE).
MDSE practices have proved to increase efficiency and effectiveness in software development. MDSE adoption in the software industry is foreseen to grow exponentially in the near future, e.g., due to the convergence of software development and business analysis.
This book is an agile and flexible tool to introduce you to the MDE and MDSE world, thus allowing you to quickly understand its basic principles and techniques and to choose the right set of MDE instruments for your needs so that you can start to benefit from MDE right away.
The first part discusses the foundations of MDSE in terms of basic concepts (i.e., models and transformations), driving principles, application scenarios and current standards, like the wellknown MDA initiative proposed by OMG (Object Management Group) as well as the practices on how to integrate MDE in existing development processes.
The second part deals with the technical aspects of MDSE, spanning from the basics on when and how to build a domain-specific modeling language, to the description of Model-to-Text and Model-to-Model transformations, and the tools that support the management of MDE projects.
The book covers the MD* world, metamodeling, domain specific languages, model transformations, reverse engineering, OMG's MDA, UML, OCL, ATL, QVT, MOF, Eclipse, EMF, GMF, TCS, xText.

Abstract: As software becomes more ubiquitous and pervasive in today’s interconnected and instrumented world, software engineering—as a practice and as a research topic—is having a hard time keeping up. In this panel, we invite FSE 2016’s participants to engage with five prominent software engineering researchers as they reflect on the state of current software engineering research and share how they each believe our work impacts (or should impact) science, society and industry. Our panelists will discuss whether our community as a whole is achieving the right balance of science, engineering and design in its combined research efforts. This lively and interactive panel discussion will also highlight new areas of research that our community should pay more attention to, as well as suggest new ways of conducting research that could improve the impact of software engineering research in the near and distant future.

The software development life cycle (SDLC) is a framework defining tasks performed at each step in the software development process. SDLC is a structure followed by a development team within the software organization. It consists of a detailed plan describing how to develop, maintain and replace specific software.
Software development process models
Rapid Application Development (RAD) Model
Evolutionary Process Models
Spiral Model
THE FORMAL METHODS MODEL
Specialized Process Models
The Concurrent Development Model
Agile software development is a group of software development methods in which requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development, early delivery, continuous improvement, and encourages rapid and flexible response to change.
The Agile development model is also a type of Incremental model. Software is developed in incremental, rapid cycles. This results in small incremental releases with each release building on previous functionality. Each release is thoroughly tested to ensure software quality is maintained. It is used for time critical applications.

We describe the deployment and use of Globus Compute for remote computation. This content is aimed at researchers who wish to compute on remote resources using a unified programming interface, as well as system administrators who will deploy and operate Globus Compute services on their research computing infrastructure.
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.
Why React Native as a Strategic Advantage for Startup Innovation.pdfayushiqss
Do you know that React Native is being increasingly adopted by startups as well as big companies in the mobile app development industry? Big names like Facebook, Instagram, and Pinterest have already integrated this robust open-source framework.
In fact, according to a report by Statista, the number of React Native developers has been steadily increasing over the years, reaching an estimated 1.9 million by the end of 2024. This means that the demand for this framework in the job market has been growing making it a valuable skill.
But what makes React Native so popular for mobile application development? It offers excellent cross-platform capabilities among other benefits. This way, with React Native, developers can write code once and run it on both iOS and Android devices thus saving time and resources leading to shorter development cycles hence faster time-to-market for your app.
Let’s take the example of a startup, which wanted to release their app on both iOS and Android at once. Through the use of React Native they managed to create an app and bring it into the market within a very short period. This helped them gain an advantage over their competitors because they had access to a large user base who were able to generate revenue quickly for them.

3. What is Engineering?
What is Software?
What is software engineering?
What is a software process?
Different types of process models?
Different Models with Strengths and Weaknesses
Agile Software Development
4. Engineering is the application of scientific
and practical knowledge in order to invent,
design, build, maintain, and improve
systems, processes, etc.
5. The software is collection of Integrated programs
Software consists of carefully-organized instructions and
code written by programmers in any of various special
computer languages.
Computer programs and associated documentation such
as requirements, design models and user manuals.
6. Software engineering is an engineering discipline that is
concerned with all aspects of software production.
According to IEEE's definition software engineering can
be defined as the application of a systematic, disciplined,
quantifiable approach to the development, operation, and
maintenance of software, and the study of these
approaches; that is, the application of engineering to
software.
7. A framework that describes the activities performed at each stage of
a software development project.
A set of activities whose goal is the development or evolution of
software.
Generic activities in all software processes are:
Specification - what the system should do and its development
constraints
Development - production of the software system
Validation - checking that the software is what the customer
wants
Evolution - changing the software in response to changing
demands.
10. Easy to understand, easy to use
Provides structure to inexperienced staff
Milestones are well understood
Good for management control (plan, staff, track)
Works well when quality is more important than cost or
schedule
11. All requirements must be known upfront
Deliverables created for each phase are considered frozen
inhibits flexibility
Can give a false impression of progress
Does not reflect problem-solving nature of software
development – iterations of phases
Integration is one big bang at the end
Little opportunity for customer to preview the system
(until it may be too late)
12. Requirements are very well known
Product definition is stable
Technology is understood
New version of an existing product
Porting an existing product to a new platform.
High risk for new systems because of specification
and design problems
13. Whole requirement is divided into various builds
Multiple development cycles take place here, making the
life cycle a “multi-waterfall” cycle.
Cycles are divided up into smaller, more easily managed
modules.
Each module passes through the requirements, design,
implementation and testing phases.
A working version of software is produced during the first
module, so you have working software early on during the
software life cycle.
14.
15. Generates working software quickly and early during the
software life cycle.
More flexible – less costly to change scope and
requirements.
Easier to test and debug during a smaller iteration.
Customer can respond to each built.
Lowers initial delivery cost.
16. Needs good planning and design.
Needs a clear and complete definition of the whole system
before it can be broken down and built incrementally.
Total cost is higher than waterfall.
17. Requirements of the complete system are clearly defined
and understood.
Major requirements must be defined; however, some
details can evolve with time.
There is a need to get a product to the market early.
A new technology is being used
Resources with needed skill set are not available
18. Rapid Application Development model
type of incremental model
In RAD model the components or functions are developed
in parallel as if they were mini projects.
The developments are time boxed, delivered and then
assembled into a working prototype.
This can quickly give the customer something to see and
use and to provide feedback regarding the delivery and
their requirements.
21. Depends on strong team and individual performances for
identifying business requirements.
Only system that can be modularized can be built using
RAD
Requires highly skilled developers/designers.
High dependency on modeling skills
Inapplicable to cheaper projects as cost of modeling and
automated code generation is very high.
22. RAD should be used when there is a need to create a
system that can be modularized in 2-3 months of time.
It should be used if there’s high availability of designers
for modeling and the budget is high enough to afford their
cost along with the cost of automated code generating
tools.
RAD SDLC model should be chosen only 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).
23. The spiral model is similar to the incremental model, with
more emphasis placed on risk analysis.
The spiral model has four phases: Planning, Risk Analysis,
Engineering and Evaluation.
A software project repeatedly passes through these phases
in iterations (called Spirals in this model).
The baseline spiral, starting in the planning phase,
requirements are gathered and risk is assessed.
24.
25. High amount of risk analysis hence, avoidance of Risk is
enhanced.
Good for large and mission-critical projects.
Strong approval and documentation control.
Additional Functionality can be added at a later date.
26. Can be a costly model to use.
Risk analysis requires highly specific expertise.
Project’s success is highly dependent on the risk analysis
phase.
Doesn’t work well for smaller projects.
27. 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)
28. Traditional approach to managing software development
projects was failing far too often, and there had to be a
better way
Agile development is a different way of managing IT
development teams and projects
Came up with the agile manifesto, which describes 4
important values that are as relevant today
29. Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
30. 1. Active user involvement is imperative
2. The team must be empowered to make decisions
3. Requirements evolve but the timescale is fixed
4. Capture requirements at a high level
5. Develop small, incremental releases and iterate
31. 6. Focus on frequent delivery of products
7. Complete each feature before moving on to the next
8. Apply the 80/20 rule
9. Testing is integrated throughout the project lifecycle – test
early and often
10. A collaborative & cooperative approach between all
stakeholders is essential
32. Is also an agile development method, which concentrates
particularly on how to manage tasks within a team-based
development environment.
Scrum is the most popular and widely adopted agile
method
Relatively simple to implement and addresses many of the
management issues that have plagued IT development
teams for decades
33. •A product owner creates a prioritized wish list called a product backlog.
•During sprint planning, the team pulls a small chunk from the top of that
wish list, a sprint backlog, and decides how to implement those pieces.
•The team has a certain amount of time — a sprint (usually two to four
weeks) — to complete its work, but it meets each day to assess its progress
(daily Scrum).
•Along the way, the Scrum Master keeps the team focused on its goal.
•At the end of the sprint, the work should be potentially shippable: ready
to hand to a customer, put on a store shelf, or show to a stakeholder.
•The sprint ends with a sprint review.
•As the next sprint begins, the team chooses another chunk of the product
backlog and begins working again-
34.
35. XP (Extreme Programming) is a more radical agile
methodology,
Focusing more on the software engineering process
Addressing the analysis, development and test phases
with novel approaches that make a substantial difference
to the quality of the end product.
36. 1. You need to improve communication.
2. You need to seek simplicity.
3. You need to get feedback on how well you are doing.
4. You need to always proceed with courage.
37. In XP these four basic activities are implemented by using
practices which are traditional software engineering
practices but elevated to embody and encourage XP
values.
Although practices of Extreme Programing they can be
compacted into twelve simple rules
38. 1. User stories (planning): User stories can be viewed as a smaller version of use case. In this way, the
customer define as briefly as possible the specification of the new application (features, value, priority).
These stories will be the base for the project team to do cost estimation and management of the project.
2. Small releases (building blocks): XP emphasizes on small, simple but frequent versions updates of the
application. Each newly added requirement will instantly incorporated and the system is re-released.
3. Metaphor (standardized naming schemes): Developers and programmers must adhere to standards on
names, class names and methods.
4. Collective ownership: In XP methodology, all code is considered to be owned by the whole team and not
an individual property. Hence, all code is reviewed and updated by everyone.
5. Coding standard: Styles and formats of coding must be the same in order to enable compatibility
between team members. This approach results in more rapid collaboration.
6. Simple design: Always look for system implementation that is as easy as possible implementation of
the system yet meets all required functionality.
39. 7. Refactoring: The application should be continually adjusted and improved by all team
members. This requires extremely good communication between members to avoid work
duplication.
8. Testing: Every small release (called building block) must pass tests before being released.
XP’s uniqueness in this aspect is that tests are created first and then application code is
developed to meet and pass the challenges of those pre-written tests.
9. Pair programming: XP programmers work in pairs. All code is developed by two
programmers who work together at a single machine. The expectation is that pair programming
produces higher quality code at the same or less cost.
10. Continuous integration: Software builds are completed several times a day. In this way all
developers can avoid work fragmentations because they continuously releasing and integrating
code together.
11. 40-hour workweek: Keep mental and physical conditions to be up and running by not
working more than what the bodies can handle.
12. On-site customer: The customer must be viewed as an integral part of the project. The
customer must be arranged to be available at all times in order to ensure that the project is in the
right track.
