An approach to reconcile the agile and CMMI contexts in product line development

Software product line approaches produce reusable platforms and architectures for products set developed by specific companies. These approaches are strategic in nature requiring coordination, discipline, commonality and communication. The Capability Maturity Model (CMM) contains important guidelines for process improvement, and specifies "what" we must have into account to achieve the disciplined processes (among others things). On the other hand, the agile context is playing an increasingly important role in current software engineering practices, specifying "how" the software practices must be addressed to obtain agile processes. In this paper, we carry out a preliminary analysis for reconciling agility and maturity models in software product line domain, taking advantage of both.Postprint (published version

Designing a consulting services architecture model

textDuring my years of experience in the technology industry, it has become obvious that standard processes and methodologies within the engineering discipline are at a mature state. The realization though is that software engineering specifically lags behind. Most software engineering methodologies that I have studied focus on the mission of software development. It is this realization and the need for structure that led me to review existing methodologies used within my company's software services organization. The definition of what a successful software services methodology entails is rather limited. This report will provide a history of existing software engineering methodologies that I have studied, describe an initial services method that was being developed within my organization, develop a new model that addresses previous shortcomings and identify additional components required to further define a strong software services-oriented delivery methodology.Electrical and Computer Engineerin

Process-based Organization Design Model: Theoretical Review and Model Conceptualization

The complexity of today's business world is translated into complexity of the company's organization design (Galbraith, 2002). Organizations are forced to quickly adapt to emerging complexity if they want to survive. The change is addressing all areas of business, especially questioning organizational effectiveness and trying to find optimal solutions for doing business. In accordance with requirements, competitive trends are pushing executives to rethink traditional design configurations. Factors such as increased competition in cost, quality and service, and technical change have forced companies not only to seek out new ways of doing old tasks, but also new ways of organizing either old or new tasks (Cross, 1990). Such focus on the flow of work within organizations, but as well as between them, is emphasizing process orientation as a new management paradigm. Inefficiencies of the two most commonly present structures – functional and divisional, in addition to emerging business trends, place the emphasis on a process-based organization as one of the possible solutions. The process-based organization is lead by the process paradigm, which is focused on the horizontal view of business activities and alignment of organizational systems towards business processes. Regardless of a large interest on business processes, existing organization design theory offers only general guidelines for process-based organizations or more precisely, a process-based organization design model. Consequently, the purpose of the paper is to demystify process-based organization design model. By clearly distinguishing between different levels of process orientation, and by addressing characteristics of the chosen model the paper will lead to better understanding of this way of organizing. Eventually, an operationalized model of process-based organization is developed. Furthermore, the paper elaborates on differences between process-based and other organizational structures and philosophies (e.g. functional, product, matrix, project, team-based). Besides structural elements, which will be in the primary focus, the paper will discuss the alignment of all other important organization design elements for process environment (e.g., management style, reward systems, performance metrics, people practices, organizational culture, etc.). There would be proposed necessary adjustments of organizational elements which should be aligned with the process-based structural solution. In such way, some of the blind spots of process-based organization design model would be revealed, providing practical implications for its implementation and ultimately, offering solution for rising business complexity.organization design, process-based organization, process-based organization design model, business processes

Developing an Intervention Toolbox for the Common Health Problems in the Workplace

Development of the Health ↔ Work Toolbox is described. The toolbox aims to reduce the workplace impact of common health problems (musculoskeletal, mental health, and stress complaints) by focusing on tackling work-relevant symptoms. Based on biopsychosocial principles this toolbox supplements current approaches by occupying the zone between primary prevention and healthcare. It provides a set of evidence-informed principles and processes (knowledge + tools) for tackling work-relevant common health problems. The toolbox comprises a proactive element aimed at empowering line managers to create good jobs, and a ‘just in time’ responsive element for supporting individuals struggling with a work-relevant health problem. The key intention is helping people with common health problems to maintain work participation. The extensive conceptual and practical development process, including a comprehensive evidence review, produced a functional prototype toolbox that is evidence based and flexible in its use. End-user feedback was mostly positive. Moving the prototype to a fully-fledged internet resource requires specialist design expertise. The Health ↔ Work Toolbox appears to have potential to contribute to the goal of augmenting existing primary prevention strategies and healthcare delivery by providing a more comprehensive workplace approach to constraining sickness absence

Four facets of a process modeling facilitator

Business process modeling as a practice and research field has received great attention in recent years. However, while related artifacts such as models, tools or grammars have substantially matured, comparatively little is known about the activities that are conducted as part of the actual act of process modeling. Especially the key role of the modeling facilitator has not been researched to date. In this paper, we propose a new theory-grounded, conceptual framework describing four facets (the driving engineer, the driving artist, the catalyzing engineer, and the catalyzing artist) that can be used by a facilitator. These facets with behavioral styles have been empirically explored via in-depth interviews and additional questionnaires with experienced process analysts. We develop a proposal for an emerging theory for describing, investigating, and explaining different behaviors associated with Business Process Modeling Facilitation. This theory is an important sensitizing vehicle for examining processes and outcomes from process modeling endeavors

Methodological bricolage: What does it tell us about design?

This paper explores an approach to design research that is becoming more prevalent in practice-based doctoral studies and examines what it tells us about the current state of design research. A previous examination of design PhD case studies has shown that the bricolage approach is evident in a majority of contemporary practice-based design PhDs [1]. The usual academic norm of using an established method or methodology is often discarded in favour of a ‘pick and mix’ approach to select and apply the most appropriate methods. Does it suggest a discipline in crisis, where existing methods are unfit for purpose? Or does this suggest that design as a discipline is maturing and developing a distinct research model? Is design undisciplined? The paper answers these questions by proposing that design researchers navigate a complex, indeterminate and temporal framework where the bricoleur is the best operative

Modelling and Forecasting the Yield Curve under Model uncertainty

This paper proposes a procedure to investigate the nature and persistence of the forces governing the yield curve and to use the extracted information for forecasting purposes. The latent factors of a model of the Nelson-Siegel type are directly linked to the maturity of the yields through the explicit description of the cross-sectional dynamics of the interest rates. The intertemporal dynamics of the factors is then modeled as driven by long-run forces giving rise to enduring effects, and by medium- and short-run forces producing transitory effects. These forces are re-constructed in real time with a dynamic filter whose embedded feedback control recursively corrects for model uncertainty, including additive and parameter uncertainty and possible equation misspecifications and approximations. This correction sensibly enhances the robustness of the estimates and the accuracy of the out-of-sample forecasts, both at short and long forecast horizons.
