Conway's Law

Any organization that designs a system (defined broadly) will produce a design whose structure is a copy of the organization's communication structure.

Information Architecture

Information architects are the people who organize, structure, and label information.

“If you understand how the web site should be organized to serve your customers, then you know how the company should be organized.”

University 2.0? The „social web‟

“There has been a cultural and pervasive shift in the nature of the internet.”

“The biggest challenge to harnessing the collective intelligence of the world to help solve some of the very serious problems we have around sustainability….has to do with people knowing not only how to use the software, but ideas around critical thinking and collaboration.”

– Howard Rheingold

Learning Theory

“social learning is based on the premise that our understanding of content is socially constructed through conversations about that content and through grounded interactions, especially with others, around problems or actions. The focus is not so much on what we are learning but on how we are learning” (Seely Brown, J. & Adler, R, 2008)

e/m-learning Systems: Applying Intelligent Technologies

There is a need to reconceptualise learning for the mobile age, to recognise the essential role of mobility and communication in the process of learning, and also to indicate the importance of context in establishing meaning.

Нужно е да се преосмисли концепцията за учене в мобилните времена, да се разбере съществената роля на мобилността и комуникациите в процеса на учене, както и да се отбележи значимостта на контекстта в обяснението на смисъла.

Глобализация на изследванията и обучението

Живеем в мобилно общество с постоянно нарастване на глобализацията.

Глобалните ресурси, глобалния пазар и глобалния пазар на труда означава, че работниците и клиентите, които се налага да обучаваме могат да бъдат навсякъде по света.

Мобилните знания и обучение се придвижват напред от движещите сили на мобилния бизнес и обществото.

Среди за онлайн обучение

Разпространение на обучителните дейности и ресурси към всички участници Независимо от това къде се намират участниците и ресурсите

Да позволяват обучение в отворена, динамична, обемна и хетерогенна среда.

Да осигурят формално и неформално обучение обучаемите независимо къде се намират да комуникират помежду си

Мобилното обучение има съществена роля в този контекст чрез използване на всички предимства които мобилните технологии предлагат – обучение навсякъде и по всяко време.

Socio-Technical Ecosystems

A socio-technical ecosystem is a community of managerially and operationally independent organizations interacting with each other and with their environment.

It targets people and technology in the work place, in addition to social and technical aspects that dictate how we do our jobs, interact with one another and incorporate new technologies into our lives.

It also encompasses physical and non-physical technological interactions and dependencies, like the relationships we build.

James Herbsleb is a Professor in the School of Computer Science at Carnegie Mellon University. His research interests focus on collaboration and coordination in software and systems engineering projects. His research iterates over empirical studies, theory development, and design and deployment of technology.

Asking a Different Question

Rather than ask “How can I specify, design, and build the system that my

stakeholders need?”

Maybe we should ask “How can I set up the socio-technical system that will

allow users, consultants, businesses, and everyone else to cooperatively build what all my stakeholders need?”

“Even though those needs are currently unknowable and

evolving . . .”

Software Architecture for Software Intensive Systems

There are many definitions in the literature

November 13, 2012

Slide 25

The software architecture of a

computing system is the set of

structures needed to reason about

the system, which comprise

software elements, relations among

them and properties of both.

Documenting Software Architecture: Views and Beyond, 2nd Ed. Clements et al. 2010.

David Garlan is a Professor in the School of Computer Science at Carnegie Mellon University, where he leads several research projects and is the Director of Professional Software Engineering Programs.

His interests include software architecture, self-adaptive systems, formal methods, and cyber-physical systems.

He is considered to be one of the founders of the field of software architecture, and, in particular, formal representation and analysis of architectural designs In 2005 he received a Stevens Award Citation for fundamental contributions to the development and understanding of software architecture as a discipline in software engineering.

Quality Attributes

Define qualities that a system must have beyond its functionality

Includes things like: •Performance •Security •Availability •Portability •… Sometimes called “non-functional”

Security CIA - Confidentiality, Integrity, and Availability

Confidentiality

• Preserving the confidentiality of information means preventing unauthorized parties from accessing the information or perhaps even being aware of the existence of the information. I.e., secrecy.

Integrity

• Maintaining the integrity of information means that only authorized parties can manipulate the information and do so only in authorized ways.

Availability

• Resources are available if they are accessible by authorized parties on all appropriate occasions.
