Managing requirements in market-driven software project: Agile methods view
Vrijeme do plasiranja na tržište i nedovoljno početno saznanje o potrebama dva su značajna problema po kojima se organiziranje potreba kod projekata razvijanja softvera za tržište razlikuje od projekata za softver po narudžbi. Ti se problemi mogu riješiti primjenom agilnih metodologija razvoja softvera kad se radi o tržišno orijentiranom softveru budući da Agilne metode naglašavaju dinamički pristup organiziranju potreba usko povezan s iterativnim ciklusom isporuke. U ovom radu, dinamički pristup Agilnih metoda definiranju potreba koristi se za uspješnu implementaciju složenog tržišno orijentiranog softverskog projekta.Time-to-market and insufficient initial requirements are two significant challenges that make managing requirements for market-driven software projects different from custom-made software projects. These challenges can be resolved by using agile software development methodologies for market-driven software development as agile methods put emphasis on a dynamic approach for requirement engineering which works closely with an iterative release cycle. In this study, dynamic requirement engineering approach of Agile methods was used for the successful implementation of market-driven complex software project
Understanding and supporting large-scale requirements management
Large market-driven software companies face new challenges in requirements engineering and management that emerged due to their recent extensive growth. At the same time, the pressure generated by competitors’ and users’ expectations demands being more competitive, creative and flexible to more quickly respond to a rapidly changing market situation. In the pursuit of staying competitive in this context, new ideas on how to improve the current software engineering practice are requested to help maintaining the engineering efficiency while coping with growing size and complexity of requirements engineering processes and their products. This thesis focuses on understanding and supporting large-scale requirements management for developing software products to open markets. In particular, this thesis focuses on the following requirements management activities in the mentioned context, namely: scope management, variability management and requirements consolidation. The goals of the research effort in this thesis are to provide effective methods in supporting mentioned requirements management activities in a situation when the size of them and their complexity require large time and skills efforts. Based on empirical research, where both quantitative and qualitative approaches were utilized, this thesis reports on possible improvements for managing variability and presents visualization techniques to assist scope management for large-scale software product development contexts. Both reported ideas are empirically evaluated in case studies in a large-scale context. Additionally, the benefits of using linguistic methods for requirements consolidation are investigated in a replicated experimental study based on a relevant industry scenario
IMPERATIVES FOR DEEPENING CUSTOMER SERVICE DELIVERY IN THE NIGERIAN BANKING SECTOR THROUGH ENGINEERING AND TECHNOLOGY-BASED CHANNELS
The study was designed to identify basic factors required to deepen adoption of
internet banking in the delivery of banking services to a rapidly growing market
characterized by complexities in service requirements. Analysis of data collected from
selected customers of 5 DMBs in Lagos, Ogun and Ebonyi States of Nigeria showed
that alternative service channels offered by technology-based applications enhanced
the delivery of banking services to bank customers. Specifically, the result showed
significant impact of ease of access, cost, reliability, and security/integrity of
technology-driven service delivery channels on the adoption of engineering
technology-based applications in Nigeria's banking industry
Human factors in developing automated vehicles: A requirements engineering perspective
Automated Vehicle (AV) technology has evolved significantly both in complexity and impact and is expected to ultimately change urban transportation. Due to this evolution, the development of AVs challenges the current state of automotive engineering practice, as automotive companies increasingly include agile ways of working in their plan-driven systems engineering—or even transition completely to scaled-agile approaches. However, it is unclear how knowledge about human factors (HF) and technological knowledge related to the development of AVs can be brought together in a way that effectively supports today\u27s rapid release cycles and agile development approaches. Based on semi-structured interviews with ten experts from industry and two experts from academia, this qualitative, exploratory case study investigates the relationship between HF and AV development. The study reveals relevant properties of agile system development and HF, as well as the implications of these properties for integrating agile work, HF, and requirements engineering. According to the findings, which were evaluated in a workshop with experts from academia and industry, a culture that values HF knowledge in engineering is key. These results promise to improve the integration of HF knowledge into agile development as well as to facilitate HF research impact and time to market

A knowledge system to support manufacturing knowledge during preliminary design
The integration of manufacturing knowledge into the product introduction process is presented as a knowledge management problem. Concurrent engineering techniques are highly effective in sharing manufacturing knowledge, particularly for the re-use of knowledge at the detail design stage when the geometry has been developed. This research considers the use of manufacturing knowledge in the earlier, preliminary stage of design where the geometry is not so developed and where development of manufacturing technology may be required. An exploratory case study was carried out with a manufacturer of gas turbine engines for the civil aviation market. Semi-structured interviews were carried out to investigate the manufacturing knowledge required and its format. Using a data-driven analysis, a thematic code was developed and three themes emerged: manufacturing impact, expressions of impact and knowledge type. These themes indicate the requirement for a hybrid social-technical system to support both the tacit and explicit elements of manufacturing knowledge. An indication of the maturity of the manufacturing process also emerged as a major requirement in order to synchronize manufacturing technology developments with future product requirements. A prototype knowledge system is now being developed to meet the requirements identified through the coding analysis. The specification of the system, which uses a combination of information and social systems, is discussed
An Empirical Study on Decision making for Quality Requirements
[Context] Quality requirements are important for product success yet often
handled poorly. The problems with scope decision lead to delayed handling and
an unbalanced scope. [Objective] This study characterizes the scope decision
process to understand influencing factors and properties affecting the scope
decision of quality requirements. [Method] We studied one company's scope
decision process over a period of five years. We analyzed the decisions
artifacts and interviewed experienced engineers involved in the scope decision
process. [Results] Features addressing quality aspects explicitly are a minor
part (4.41%) of all features handled. The phase of the product line seems to
influence the prevalence and acceptance rate of quality features. Lastly,
relying on external stakeholders and upfront analysis seems to lead to long
lead-times and an insufficient quality requirements scope. [Conclusions] There
is a need to make quality mode explicit in the scope decision process. We
propose a scope decision process at a strategic level and a tactical level. The
former to address long-term planning and the latter to cater for a speedy
process. Furthermore, we believe it is key to balance the stakeholder input
with feedback from usage and market in a more direct way than through a long
plan-driven process
Comparative Study on Agile software development methodologies
Today-s business environment is very much dynamic, and organisations are
constantly changing their software requirements to adjust with new environment.
They also demand for fast delivery of software products as well as for
accepting changing requirements. In this aspect, traditional plan-driven
developments fail to meet up these requirements. Though traditional software
development methodologies, such as life cycle-based structured and object
oriented approaches, continue to dominate the systems development few decades
and much research has done in traditional methodologies, Agile software
development brings its own set of novel challenges that must be addressed to
satisfy the customer through early and continuous delivery of the valuable
software. It is a set of software development methods based on iterative and
incremental development process, where requirements and development evolve
through collaboration between self-organizing, cross-functional teams that
allows rapid delivery of high quality software to meet customer needs and also
accommodate changes in the requirements. In this paper, we significantly
identify and describe the major factors, that Agile development approach
improves software development process to meet the rapid changing business
environments. We also provide a brief comparison of agile development
methodologies with traditional systems development methodologies, and discuss
current state of adopting agile methodologies. We speculate that from the need
to satisfy the customer through early and continuous delivery of the valuable
software, Agile software development is emerged as an alternative to
traditional plan-based software development methods. The purpose of this paper,
is to provide an in-depth understanding, the major benefits of agile
development approach to software development industry, as well as provide a
comparison study report of ASDM over TSDM.Comment: 25 pages, 25 images, 86 references used, with authors biographie
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
Traceability for Model Driven, Software Product Line Engineering
Traceability is an important challenge for software organizations. This is true for traditional software development and even more so in new approaches that introduce more variety of artefacts such as Model Driven development or Software Product Lines. In this paper we look at some aspect of the interaction of Traceability, Model Driven development and Software Product Line
