"Social
Modeling
for
Requirements
Engineering"
- Hot off the press!
November 15, 2010
From MIT Press: "This
book offers a new approach to the
requirements challenge, based on modeling
and analyzing the relationships among
stakeholders. The i* framework
conceives of software-based information
systems as being situated in environments in
which social actors relate to each other in
terms of goals to be achieved, tasks to be
performed, and resources to be furnished.
The book includes Eric Yu's original
proposal for the i* framework as
well as research that applies, adapts,
extends, or evaluates the social modeling
concepts and approach."
Chapter 2 is a reprint of Eric
Yu's doctoral dissertation from 1995.
It is followed by 18 chapters authored
by researchers from around the world who
have applied, adapted, or extended the i*
framework in various ways, and for diverse
application contexts – from business
processes to knowledge management to air
traffic control, from information security
to software development.

The i*
framework is now part of an international
standard!
November
13, 2008
The User
Requirements Notation (URN) received
final approval as an international standard
today in Geneva, Switzerland, as ITU-T
Recommendation Z.151. URN consists
of the Goal-oriented Requirements Language
(GRL), based on Professor Eric Yu's i*
modelling framework, and Use Case Maps
(UCM), a scenario modelling notation. GRL
provides a notation for modelling goals and
rationales, and strategic relationships among
social actors. It is used to explore and
identify system requirements, including
especially non-functional requirements. Thanks
to the many students, research team members,
colleagues, and international collaborators
who contributed directly or indirectly. ITU is the UN
agency for information and communication
technologies.
Consider these challenges facing the computing profession:
Most software systems are hard to maintain and evolve.
Most software is hard to reuse.
Most software systems are hard to interoperate with other
systems.
Many software systems do not meet user needs, especially as
the needs change.
These issues are being addressed in many different ways in computing
research. My contention is that all these problems have to do
with a missing representational dimension in software. This is
the intentional dimension - the realm of knowledge
representation that deals with intents and motivations, goals and
reasons, alternatives and choices, beliefs and assumptions.
Software development is a knowledge-intensive activity.
Some of the most important knowledge involved in constructing and
maintaining software include:
why is this operation / data structure needed or used?
(intents and motivations)
what am I trying to achieve here? why am I trying to
achieve this? (goals and reasons)
what are the possible designs, and why choose one over
another? (alternatives and choices)
what is the basis for making this design decision? (beliefs
and assumptions)
Current software representations emphasize operations on data
(programming languages) or assertions about properties
(specifications). Requirements describe the relationship between the
system and the environment, usually in terms of activities and
information flows, constraints, and so on. These
representations (modelling schemes and languages) are
non-intentional. They do not allow intentional aspects to be
expressed. Yet, intentional concepts are used throughout the
actual work of software development. During a software
project, goals are set, some are achieved, others are revised,
sometimes abandoned. Alternatives are generated and assessed; some
are further explored, selected, and become part of the solution.
Assumptions are made, validated, sometimes withdrawn. Hidden
assumptions are revealed and challenged. Furthermore, these
intentional concepts are manipulated within group and team
settings. Intentionality originates from the many
organizational participants and stakeholders in a project.
They bring competing and complementary demands and knowledge and
skills and values. Multiple systems that interact or
components within a system may carry intentionality from different
stakeholders.
All of these are part and parcel of everyday software work.
Yet, existing representations hardly support these intentional
processes and relationships. Non-intentional representations
that are in common use today are appropriate for recording the
results of software work, but not the process or the reasoning
behind them. My contention is that this missing knowledge
contributes in large part to the difficulty in understanding,
evolving, and reusing software, and in making them interoperate.
In fact, the product of software work should include not just
executable code, and not just designs and specifications and
requirements expressed in non-intentional terms, but also the rich
interconnected web of intentional relationships.
Using Intentional Relationships to Link
Business Requirements to Design to Execution and Monitoring
In our research, we are using intentional relationships to link
representations of business requirements, architectural design,
and run-time operations. The main relationships are goal
refinement and means-ends relationships and argumentation (beliefs
and assumptions). These intentional relationships capture
and support the reasoning process for deriving execution-level
processes from architectural designs, which in turn are derived
from business requirements. The use of intentional concepts
provide guidance and support during the forward engineering
process. They also provide the key linkages needed for
supporting evolution. Run-time operations are monitored against
requirements.
Intentional Relationships Among Agents
Intentional modelling needs to characterize what an agent wants,
and how these wants are met by the abilities of other
agents. If wants and abilities do not match up, there needs
to be adjustments on either or both sides. This is done by
going up or down the means-ends and task-decomposition structures
of agents and re-distributing responsibilities among agents. The
strategic implications of various alternative re-structuring of
intentional dependencies among agents need to be analyzed. This is
an important step during requirements analysis. Much of
Requirement Engineering research focuses on requirements
specification of behaviour rather than on high-level strategic
requirements.
Putting Intentionality into Software
Architecture
We believe that software should be characterized as intentional
structures. Current conceptions of software architecture
view architectural units or components as behavioural units which
interact with each other through messages, data and control flow,
etc. This characterization omits important aspects which are
at the intentional level of description. We would like to
view software components as having wants and abilities, and
depending on each other in order to achieve goals.
Research Issues
Given the above overall philosophy and objectives, there are
specific research questions to be addressed. An immediate
challenge is the large amounts of knowledge that needs to be
explicitly represented and managed. Since making knowledge
explicit has both benefits and costs, these need to be balanced.
Research questions include:
What kinds of knowledge do we need? What should the
knowledge be about? What are the appropriate ontological
concepts?
How do we represent and organize the knowledge? What
abstraction mechanisms and structuring dimensions are
needed? What are their semantics and computational
properties?
How can we exploit the knowledge? What analysis
techniques can be devised? What questions/queries should
be answerable?
How do we construct new knowledge structures from existing
ones?
We are studying these in software project teams, extracting
experiences, and trying out representation schemes and improving
upon them. There are more specific research issues for each area in
which we apply this "intentional paradigm". See Research Areas.
More generally, we are dealing with the management of complex
knowledge products and processes -- supporting the construction,
maintenance, exploitation, and evolution of knowledge artifacts.
The software development setting is but one example of complex
knowledge-intensive work settings. See Knowledge Management Lab.
The intentional paradigm is being applied to several
projects. See Research
Projects.
Research Areas
My research centres around the concept of strategic agents.
More specifically, my research goal is to develop techniques for
modelling, analyzing, and redesigning relationships among
intentional, strategic actors. Application areas are outlined
below. These include information systems analysis and design,
requirements engineering, software engineering, business modelling
and redesign, and knowledge management.
Requirements
Analysis
and Systems Design
Information Systems Analysis and Design My research objective is to develop an "agent-oriented"
approach to systems analysis and design that focuses on the
intentional, strategic character of organization actors. Such an
approach would provide a better match for the increasingly flat,
networked organizations of today and for the emerging
agent-oriented computing paradigm.
Agent-Oriented and Goal-Oriented Requirements Engineering
As software technologies advance, attention is increasingly being
focused on the early phases of system development. Getting the
requirements right remains one of the foremost challenges in
software engineering. Requirements engineering is now firmly
established as a research area with its own conferences (RE,
REFSQ) and a journal (REj). Models and languages, tools and
methodologies are being developed. My primary interest in this
area is to develop models and techniques for helping understand
the organizational context in which systems function, and for
reasoning about such contexts. Such understanding is needed to
develop systems that address real needs, and that can evolve to
meet changing needs.
Non-Functional Requirements; Quality by Design
The approach taken partly draws on a framework for dealing with
non-functional (or quality) requirements. Besides providing
desired functionality, a system needs to meet non-functional
requirements such as accuracy, security, performance, costs, and
so forth. The ``NFR framework'' treats non-functional requirements
as goals that need to be addressed systematically and traded off
amongst each other during the design process.
Systems
Architectures and Enterprise Architectures
Software architectures The architecture of
software systems need to be described at the intentional
level, so as to characterize the wants and abilities of
components, and to analyze opportunities and vulnerabilities.
Intentional architectural descriptions fit well with
agent-oriented characterizations of enterprise. This enables
systems design to be treated as part of enterprise design. My
research objective here is to adapt strategic actor
relationships modelling to the system architecture domain.
Business Process and Enterprise
Modelling
Business processes are key to the operation of most organizations.
A thorough understanding of the business processes of an
organization is a necessary prerequisite for developing effective
IT support for those processes. Modelling (or ``mapping'')
techniques are widely used to document and to help explain,
analyze and redesign processes. The radical ``reengineering'' of
business processes highlighted the need for appropriate modelling
techniques. Today, Internet technologies and e-commerce are
leading to fundamental changes in business structures.
Traditional techniques that have been borrowed from systems
analysis and design are ill-equipped to deal with these
changes. My interest in this area is to develop and
introduce techniques that allow the strategic interests of various
stakeholders and actors to be considered when searching for
innovative process solutions and business configurations.
Strategic Business Modeling
Information systems are meant to inform business decision making
and to support business operations. However, information in IT
systems are usually organized in a way that is hard for business
decision makers to interpret and manipulate, requiring IT
specialists as intermediaries. Thus despite rapid advances in
business intelligence (BI) technologies, adoption among business
users remains slow. With strategic business modeling, the
objective is to provide a conceptual schema and language that
employs business concepts such as business goals, strategies,
processes, actors, resources, etc., so that enterprise data can be
queried and reasoned about directly through a business-friendly
language. <url: BIM on BIN site>
BI-enabled Adaptive Enterprise
Architecture.
While BI technologies are enabling decision makers to gain
business insights ever more quickly, actions prompted by those
insights cannot be implemented quickly if IT systems are
inflexible and hard to adapt. The idea in this research is take
advantage of strategic business modeling, so as to connect BI
results and insights into the information systems lifecycle more
directly. An adaptive enterprise architecture would be ready to
accommodate various kinds of change, making use of available
adaptive software architectures and mechanisms.
Software
Engineering
Software Processes and Organizations
Software engineering is concerned with the methodical, systematic
production of quality software. Despite advances in technology,
successful software engineering still relies heavily on human
efforts. To benefit from technical advances, software engineering
organizations need to continuously redesign themselves
appropriately. For example, switching to object-orientation,
adopting client/server, promoting software reuse all require
substantial organizational changes.
Software processes (e.g., software development processes,
software maintenance processes, etc.) have received considerable
attention in the software engineering field in the past decade.
Various modelling schemes have been proposed, mostly as basis for
automating or providing technological support to software
engineering activities. My interest here is to use organization
modelling techniques to better understand the implications of
various software technologies for software organizations,
and how these organizations and their processes can be designed to
better take advantage of these technological advances..
Software ecosystems
Software businesses are increasingly being organized as ecosystem.
The success of a software endeavour today relies often on a
community of users and third-party developers. Software decisions
at many levels are tied to business strategies and decisions.
Technical choices need to be understood in the context of the
strategies of many other players. The research objective is to
develop methods and techniques to bring software and business
reasoning together, to enable technical people to better
understand business strategies and business models and bring that
understanding into their technical decision making.
Software Engineering as Knowledge Management
Software engineering innovations are not merely technical in
nature, but are deeply social, with hidden assumptions about human
knowledge and skills and learning. New software techniques stand
or fall not only as a result of the soundness of their technical
advances, but more importantly because of the human social and
knowledge factors. The research objective is to analyze each
software innovation as a knowledge management innovation, so as to
provide a more detailed analysis of successes and failures, using
i*-like strategic modeling.
Agent-Oriented Software Engineering
When systems are no longer designed from scratch under a unified
grand scheme, the traditional notion of architecture which parcels
out functionality to components according to a single coherent set
of principles (e.g., flexibility, reliability, performance, reuse,
etc.) is no longer adequate. System components are increasingly
being viewed as (relatively) autonomous agents who request
services from each other. Relationships among components are no
longer adequately described by syntactic and semantic
characterizations of interfaces and interconnections. One
component may seek particular performance and reliability
characteristics on specific functionalities from the components
that it uses. These latter components may in turn depend on others
for a different set of characteristics on other functionalities.
System components may be organized via market mechanisms or
longer-term relationships, and may involve reward structures
(e.g., payments, licensing, etc.) This perspective and
approach complements the rapidly emerging agent-oriented software
technologies (at the implementation level).
Security, Privacy,
and Trust
Many formal and mathematical frameworks have been developed to deal
with computer system and network security, and more recently,
privacy and trust. The strategic actor relationships approach
allows trust, security, and privacy to be modelled and analyzed from
a social actors perspective. This approach is especially relevant
when dealing with new system architectures and business models,
e.g., in white-box security (where the attacker has full access to
the software, as in the case of software in mobile devices), or in
cloud computing.
Social
Modeling for Sustainability
Climate change and energy shortages and imbalances could lead to
unprecedented upheavals as well as opportunities for innovations and
renewals. Social modeling methods can be used to analyze various
innovations, including requirements engineering for online media to
facilitate and enable sustainable communities. Design knowledge from
past successes and failures could be mined and reused. Vast amounts
of data can be monitored and analyzed for community decision making.
Security threats need to be anticipated and addressed. Collaboration
among many parties and interest groups could be analyzed as
ecosystems. Mutually reinforcing socio-technical interactions are
crucial. Social modeling can also facilitate interdisciplinary
understanding and collaboration essential for tackling
sustainability challenges.
Conceptual
Modelling
and Knowledge
Management
The common thread through my various research interests is the
need to manage complex knowledge structures. We develop
conceptual modelling techniques to model real world phenomena, to
manage large bodies of knowledge, and to support analysis and
reasoning. The techniques aim to provide a sufficiently rich
characterization of a domain ("ontologies"), drawing on knowledge
representation techniques in artificial intelligence to provide
reasoning support.
Social
Modeling and i*
The social modeling approach initiated by the i* modeling
framework continues to see more adoption in industry and
experimentation by researchers worldwide. Despite its adoption
as part of an international standard, many research issues
remain to be addressed to attain a stronger theoretical base and
to overcome practical challenges.
Representing and Managing Design Knowledge. Design knowledge is at the heart of most technical
and engineering fields. In this research, we study the structure
of knowledge in various design domains, focusing on design know-how (means-ends knowledge, solutions to
problems or to achieve design goals).
We develop methods for extracting, compiling, and restructuring
the knowledge for later or broader reuse. The longer term vision is to
establish the means-ends relationship as a central mechanism for
structuring knowledge. Building open information infrastructures
based on this knowledge dimension could provide a significant
boost for technology and design disciplines.
