08412 Manifesto – High-Impact Requirements for Software-Intensive Systems

Authors: Matthias Jarke, Pericles Loucopoulos, Kalle Lyytinen, John Mylopoulos, and William Robinson

Abstract
Despite its undoubted success in the last two decades, requirements engineering (RE) needs a better alignment between its research focus and its grounding in practical needs as these needs have changed significantly. We identify and explore changes in the environment, targets, and the process of RE that influence the nature of fundamental RE questions. Based on these explorations we propose four key principles that underlie current requirements processes and influence their successful resolution: (1) intertwining of requirements with implementation and organizational contexts, (2) dynamic evolution of requirements, (3) architectures as a critical stabilizing force, and (4) high levels of design complexity and necessity to employ new ways to mitigate it. We make recommendations to refocus RE research agenda as to meet better emerging and new challenges based on the review and analysis of these four key themes, and note several managerial and practical implications.

'A Science of Design' is a Misled and Misleading Goal

Authors: Frederick P. Brooks

Abstract
Simon, in advocating for a Science of Design, proposed a linear Rational Model of design as his science's central concept. Such a model occurs naturally to engineers. Indeed, it has been independently formally set forth several times: e.g., by Simon, by Paul and Beitz, and by Royce. Having a visual, geometric representation of a design process model is crucial, for designers are spatial thinkers. We most easily learn, think about, share, and talk in terms of a model with a clear geometric picture. But the linear, step-by-step Rational Model is misled in goal and approach. It does not accurately reflect what real designers do, nor what the best design thinkers identify as the essence of the design process. Science and design are fundamentally different activities. The goal of a Science of Design is also misleading. Its Rational Model leads to the too-early binding of requirements, leading in turn to bloated products and schedule/budget/performance disasters. The Rational Model has persisted in practice despite its inadequacies and plenty of cogent critiques. This is because builders and clients need contracts. Several alternative process models have been proposed. I find Boehm's Spiral Model the most promising. We also need to develop alternative contracting processes, perhaps adapting those from the building community.

Action Design Research - An Integrative Research Method for Studying Design

Authors: Matti Rossi

Abstract
It is the premise of this position paper that a combination of design research and action research can be very useful for studying high performance designs. However, there has been a separation between the two approaches. A growing body of literature is recognizing these cross fertilization possibilities between AR and DR. Researchers argue for similarity between the two (J'rvinen 2007; Lee 2007; Figueiredo and Cunha 2007) as well as caution against fusion (Iivari 2007). Others suggest a middle ground stating that in some situations and contexts, the two may be integrated (Cole et al. 2005; Sein et al. 2007).

Complexity, Requirements and Design

Authors: Alistair G. Sutcliffe

Abstract
So why do we get worried about complex systems and what can we do about it? Complexity worries us because the world is unpredictable, large scale, multi component and densely interconnected. We perceived interactions as complex since we have difficulty in generalising over multiple events especially when events are poorly ordered. However interactional complexity is tractable by mathematical modeling as (misnamed) chaos theory has shown. Interactional complexity is being modeled with increasing accuracy by computational theories and simulations of physical and biological systems, viz. the IPCC world climate model. The second form is semantic complexity which implicates the difficulties we have in understanding intent of people. Here sadly there is no short term tractable solution. The Dagstuhl process of discussion leading to incremental (maybe radical) advances in understanding is one answer.

Distributed Cognition in the Management of Design Requirements

Authors: Sean Hansen and Kalle Lyytinen

Abstract
In this position statement, we outline a new theoretical framework of the distribution of design requirements processes. Building upon the Theory of Distributed Cognition, we characterize contemporary requirements efforts as distributed cognitive systems in which elements of a design vision are distributed socially, structurally, and temporally. We discuss the various forms of distribution observed in real-world systems development projects and the processes by which representational states are propagated through the system. We conclude with a brief discussion of the implications of the framework for requirements research and practice.

Effectuation for organizing design processes?

Authors: Isabelle Reymen

Abstract
Design Science Methodology is the title of a course I developed/am developing. It tries to bridge design in engineering and social science, with the goal to learn industrial engineering and management students notions of design. With an engineering background (Architecture and some Computing Science), I am now Assistant Professor Design Processes in the Organization Science and Marketing group of Prof. Romme. I lecture in the Innovation Management Program of the Eindhoven University of Technology. I am very interested in thinking about new ways of organizing design processes and about how to deal with the new challenges of design science. My research focuses around "The design of processes for artifact creation", where artifacts can be new products, systems, discourse, businesses, markets, ... . I am also involved in a new initiative that plans to organize a workshop on Organizational Design and Engineering, which I like to share with the audience.

Making sense of Design & Requirements Perspectives - & their Inter-relations

Authors: Liam Bannon

Abstract
I see myself as a commentator or discussant at this workshop as my research interests are on the "edge" of the RE area. Thus, for me, the question of what perspective we bring to bear on the issues we are debating is paramount. What I find interesting in some of the recent discussions is to what extent the issues and problems we are facing today are novel and distinct from those we were facing 10 or even 20 years ago, and how these are being discussed nowadays and heretofore. I provide some personal context for these remarks and show both some similarities and possible differences over the years in the ongoing discussions.

Requirements in the 21st Century: Current Practice and Emerging Trends

Authors: Sean Hansen, Nicholas Berente, and Kalle Lyytinen

Abstract
Requirements have remained one of the grand challenges in the design of software intensive systems. In this paper we review the main strands of requirements research over the past two decades and identify persistent and new challenges. Based on a field study that involved interviews of over 30 leading IT professionals involved in large and complex software design and implementation initiatives we review the current state-of-the-art in design requirements management. We observe significant progress in the deployment of modeling methods, tools, risk-driven design, and user involvement. We note nine emerging themes and challenges in the requirement management arena: 1) business process focus, 2) systems transparency, 3) integration focus, 4) distributed requirements, 5) layered requirements, 6) criticality of information architectures, 7) increased deployment of COTS and software components, 8) design fluidity and 9) interdependent complexity. Several research challenges and new avenues for research are noted in the discovery, specification, and validation of requirements in light of these requirements features.

Requirements Engineering for Control Systems

Authors: Dominik Schmitz

Abstract
Nowadays, more and more controllers in automobiles are realised in software on electronic control units. This contribution reports on a joined project of control system engineers and software engineers that aims at a better integration of these two disciplines. Focussing the requirements engineering part, the relevant issues for control systems are set in relation to the previously identified four key requirements principles.

Requirements Engineering for Social Software

Authors: Anna Glukhova

Abstract
Social software bears some special characteristics for requirements engineering (RE) like user-centeredness, self-organization and voluntarism. No concrete formalization of the RE process for social software has been established so far. In this position paper, important aspects of social contexts will be considered in order to define requirements, referring to the previously identified four key requirements principles.

Software Transparency

Authors: Julio Cesar Sampaio do Prado Leite

Abstract
Software transparency is a new concern that software developers must deal with. As society moves towards the digitalization of day to day processes, the transparency of these digital processes becomes of fundamental importance if citizens would like to exercise their right to know. Informed discourse is only possible if processes that affect the public are open to evaluation. Achieving software transparency to this level of openness brings up several roadblocks. This talk reports on initial findings on exploring the obstacles for enabling software transparency.

The Logic of Requirements

Authors: John Mylopoulos

Abstract
Requirements consist of (a) domain assumptions, (b) hard goals, (c) quality constraints, (d) possibly prioritized preferences. The very core of Requirements Engineering consists of the following problem: given a set of (a)-(d), generate specifications that fulfill hard goals and quality constraints, assuming that domain assumptions hold, and satisfy maximal sets of preferences. We are working towards tools that solve this problem for expressive modeling languages in terms of which one can represent domain assumptions, goals, etc. Such tools can be used as basis for exploring requirements by varying preferences and priorities, or weakening/strengthening goals.

The Case SIS Project: An Enterprise System in Higher Education

Authors: Sean Hansen and Kalle Lyytinen

Abstract
In 2006, Case Western Reserve University (Case) initiated the acquisition,  customization, and implementation of a new student information system (SIS).   The Case SIS Project was intended to integrate the capture and management of  all student information and student-facing administrative functions  across the university’s distinct schools. Key functions supported by the  platform include admissions, financial aid, course selection and enrollment,  grading, degree tracking, and transcript management. The initial roll-out of  the system was completed in the Fall 2008 semester, and additional phases will  be rolled out over the course of the 2008 - 2009 academic year.

The Summit County Integrated Public Safety Initiative: Information Sharing in Law Enforcement

Authors: Sean Hansen and Kalle Lyytinen

Abstract
The Integrated Public Safety Initiative (IPSI) is a multi-party project  aimed at establishing effective information sharing across all members  of the law enforcement community within Sumit County in Connecticut  (on the east coast of the United States).2  A regional software vendor,  Blue Systems, Inc. (BSI), has been selected to provide the information  sharing platform that forms the core of the initiative.  In this capacity,  BSI professionals are acting as the primary managers of the overall project  effort.  The project is envisioned as a multi-year effort, with the  four central law enforcement entities in the county adopting the system in  2008 and additional public safety entitiesmigrated onto the platform over  the next three (3) years.

Understanding Social and Environmental Requirements in China

Authors: Lin Liu

Abstract
Rapid changes in the social and technical environment bring about many new challenges to system requirements engineering, amongst which out-sourcing or off-shoring of certain design tasks to countries with more human resources and broader markets becomes promising business leverage. Here we report some of the result from an ongoing research project on the survey of requirements practices in China. It is interesting to understand the current status of industrial practices after years' research efforts, especially in a rapidly developing country such as the China. We perform a web-based survey of requirements engineering practices in China, focusing on the requirement elicitation techniques and requirement presentation techniques. Our study has collected data from 150+ participants from 50+ Chinese companies and education institutes. We also analyze the impact of Chinese culture on requirement engineering practices. In this report, we present the main survey results and point out their implications. We hope our results are useful for industrial practitioners and academic researchers wishing to improve current practices, and for foreign software companies wishing to better understand their Chinese customers.
