A Model-Driven Approach for Business Process Management
The Business Process Management is a common mechanism recommended by a high number of standards for the management of companies and organizations. In software companies this practice is every day more accepted and companies have to assume it, if they want to be competitive. However, the effective definition of these processes and mainly their maintenance and execution are not always easy tasks. This paper presents an approach based on the Model-Driven paradigm for Business Process Management in software companies. This solution offers a suitable mechanism that was implemented successfully in different companies with a tool case named NDTQ-Framework.Ministerio de EducaciĂłn y Ciencia TIN2010-20057-C03-02Junta de AndalucĂa TIC-578
A CMMI-compliant requirements management and development process
Requirements Engineering has been acknowledged an essential discipline for Software Quality. Poorly-defined processes for eliciting, analyzing, specifying and validating requirements can lead to unclear issues or misunderstandings on business needs and projectâs scope. These typically result in customersâ non-satisfaction with either the productsâ quality or the increase of the projectâs budget and duration. Maturity models allow an organization to measure the quality of its processes and improve them according to an evolutionary path based on levels. The Capability Maturity Model Integration (CMMI) addresses the aforementioned Requirements Engineering issues. CMMI defines a set of best practices for process improvement that are divided into several process areas. Requirements Management and Requirements Development are the process areas concerned with Requirements Engineering maturity.
Altran Portugal is a consulting company concerned with the quality of its software. In 2012, the Solution Center department has developed and applied successfully a set of processes aligned with CMMI-DEV v1.3, what granted them a Level 2 maturity certification. For 2015, they defined an organizational goal of addressing CMMI-DEV maturity level 3.
This MSc dissertation is part of this organization effort. In particular, it is concerned with the required process areas that address the activities of Requirements Engineering. Our main goal is to contribute for the development of Altranâs internal engineering processes to conform to the guidelines of the Requirements Development process area.
Throughout this dissertation, we started with an evaluation method based on CMMI and conducted a compliance assessment of Altranâs current processes. This allowed demonstrating their alignment with the CMMI Requirements Management process area and to highlight the improvements needed to conform to the Requirements Development process area. Based on the study of alternative solutions for the gaps found, we proposed a new Requirements Management and Development process that was later validated using three different approaches.
The main contribution of this dissertation is the new process developed for Altran Portugal. However, given that studies on these topics are not abundant in the literature, we also expect to contribute with useful evidences to the existing body of knowledge with a survey on CMMI and requirements engineering trends. Most importantly, we hope that the implementation of the proposed processesâ improvements will minimize the risks of mishandled requirements, increasing Altranâs performance and taking them one step further to the desired maturity level
Towards a business-IT alignment maturity model for collaborative networked organizations
Aligning business and IT in networked organizations is a complex endeavor because in such settings, business-IT alignment is driven by economic processes instead of by centralized decision-making processes. In order to facilitate managing business-IT alignment in networked organizations, we need a maturity model that allows collaborating organizations to assess the current state of alignment and take appropriate action to improve it where needed. In this paper we propose the first version of such a model, which we derive from various alignment models and theories
Major Indian ICT firms and their approaches towards achieving quality
Of the three basic theories of innovation: the entrepreneur theory, the technology-economics theory and the strategic theory, the third one seems to be highly appropriate for the analysis of recent growth of the information and communication technology (ICT) industry in many developing countries including India. The central measure for achieving quality by the various major Indian ICT firms is widely agreed to have been the adoption of Six Sigma Methodology and various other approaches like Total Quality Management (TQM), Supply Chain Management (SCM), Customer Relationship Management (CRM), etc. It is apparent that the main objective of the firms chosen has been to increase the pace of innovation activities, irrespective of their different areas of product specialisation. Its success also depends largely on the overall improvement in infrastructure, besides active market interaction. To enable both the above, a brief highlight on the establishment of interaction and learning sites (ILSs) in every regional State in India comes to the foreground. The chapter concludes with a mention of the elements observed to be missing among the firms under consideration, and, thereby, delineating the scope for their further improvement.
Software Development Process Modeling. Developers Perspective to Contemporary Modeling Techniques
Formal software development processes and well-defined development methodologies
are nowadays seen as the definite way to produce high-quality software within
time-limits and budgets. The variety of such high-level methodologies is huge
ranging from rigorous process frameworks like CMMI and RUP to more lightweight
agile methodologies. The need for managing this variety and the fact that
practically every software development organization has its own unique set of development
processes and methods have created a profession of software process
engineers. Different kinds of informal and formal software process modeling languages
are essential tools for process engineers. These are used to define processes
in a way which allows easy management of processes, for example process dissemination,
process tailoring and process enactment.
The process modeling languages are usually used as a tool for process engineering
where the main focus is on the processes themselves. This dissertation
has a different emphasis. The dissertation analyses modern software development
process modeling from the software developersâ point of view. The goal of the
dissertation is to investigate whether the software process modeling and the software
process models aid software developers in their day-to-day work and what are
the main mechanisms for this. The focus of the work is on the Software Process
Engineering Metamodel (SPEM) framework which is currently one of the most
influential process modeling notations in software engineering.
The research theme is elaborated through six scientific articles which represent
the dissertation research done with process modeling during an approximately
five year period. The research follows the classical engineering research discipline
where the current situation is analyzed, a potentially better solution is developed
and finally its implications are analyzed. The research applies a variety of different
research techniques ranging from literature surveys to qualitative studies done
amongst software practitioners.
The key finding of the dissertation is that software process modeling notations
and techniques are usually developed in process engineering terms. As a consequence
the connection between the process models and actual development work
is loose. In addition, the modeling standards like SPEM are partially incomplete
when it comes to pragmatic process modeling needs, like light-weight modeling
and combining pre-defined process components. This leads to a situation, where
the full potential of process modeling techniques for aiding the daily development
activities can not be achieved.
Despite these difficulties the dissertation shows that it is possible to use modeling
standards like SPEM to aid software developers in their work. The dissertation
presents a light-weight modeling technique, which software development teams
can use to quickly analyze their work practices in a more objective manner. The
dissertation also shows how process modeling can be used to more easily compare
different software development situations and to analyze their differences in a
systematic way. Models also help to share this knowledge with others.
A qualitative study done amongst Finnish software practitioners verifies the
conclusions of other studies in the dissertation. Although processes and development
methodologies are seen as an essential part of software development, the
process modeling techniques are rarely used during the daily development work.
However, the potential of these techniques intrigues the practitioners.
As a conclusion the dissertation shows that process modeling techniques, most
commonly used as tools for process engineers, can also be used as tools for organizing
the daily software development work. This work presents theoretical solutions
for bringing the process modeling closer to the ground-level software development
activities. These theories are proven feasible by presenting several case studies
where the modeling techniques are used e.g. to find differences in the work methods
of the members of a software team and to share the process knowledge to a
wider audience.Siirretty Doriast
Political Maneuvering During Business Process Transformation: A Pluralist Approach
For years, managers have tried to improve organizational performance through business process transformation (BPT), and their experiences have informed IS research and practice. Although extant theory acknowledges the political nature of these dynamic transformation initiatives, researchers have yet to empirically investigate and theorize how organizational politics impacts BPT behaviors and outcomes. Drawing on a pluralist methodology, we present an embedded case study of a company-wide BPT project across four business units at the high-tech firm Terma. First, we apply different perspectives on organizational politics to develop detailed accounts of each business unit\u27s response to the transformation initiative, which reveals four distinct patterns of BPT politics: âapplying the hammerâ, âstruggling to engageâ, âwalking the talkâ, and âkeeping up appearancesâ. Next, we combine the empirical findings with extant literature to theorize how transformation agents and process users engage in politics during BPT implementation. As a result, our research leverages a pluralist approach to show how alternative political perspectives and forms of politics can help managers maneuver BPT initiatives in their roles as transformation agents and process users
Agile, Web Engineering and Capability Maturity ModelI ntegration : A systematic literature review
Context
Agile approaches are an alternative for organizations developing software, particularly for those who develop Web applications. Besides, CMMI (Capability Maturity Model Integration) models are well-established approaches focused on assessing the maturity of an organization that develops software. Web Engineering is the field of Software Engineering responsible for analyzing and studying the specific characteristics of the Web. The suitability of an Agile approach to help organizations reach a certain CMMI maturity level in Web environments will be very interesting, as they will be able to keep the ability to quickly react and adapt to changes as long as their development processes get mature.
Objective
This paper responds to whether it is feasible or not, for an organization developing Web systems, to achieve a certain maturity level of the CMMI-DEV model using Agile methods.
Method
The proposal is analyzed by means of a systematic literature review of the relevant approaches in the field, defining a characterization schema in order to compare them to introduce the current state-of-the-art.
Results
The results achieved after the systematic literature review are presented, analyzed and compared against the defined schema, extracting relevant conclusions for the different dimensions of the problem: compatibility, compliance, experience, maturity and Web.
Conclusion
It is concluded that although the definition of an Agile approach to meet the different CMMI maturity levels goals could be possible for an organization developing Web systems, there is still a lack of detailed studies and analysis on the field
Validation of a Generic Service Governance Meta Model based on the Comparison of Major Governance Frameworks
The effective governance of organizational capabilities in the areas of Service Management and Service-oriented Architectures (SOA) has been broadly recognized as an essential success factor for service-oriented enterprises. Organizations that target the adoption of an adequate Service Governance approach face the difficulty of selecting from a variety of related frameworks with differing scopes and objectives. In this paper, we provide a structural comparison of the major, non vendor-specific IT and SOA Governance and Management frameworks and use this comparison to validate our own Service Governance meta model. This generic meta model is intended to provide a sound conceptualization, thereby contributing to a better understanding and facilitation of Service Governance, e.g. by forming the foundation for the development of a flexible and configurable Service Governance tool
