    Requirements engineering requires intensive collaboration among team members. The importance of collaboration in agile methods is also undeniable. Due to their emphasis on collaboration, agile methods and requirements engineering activities seem to mutually support each other in software development. However, very little is still known about the “agile way” of dealing with requirements and how collaboration driven by requirements takes place especially among distributed team members. The main aim of this research is to investigate the socio-technical aspects of requirements-driven collaboration in agile teams. Firstly, this research identified the most relevant socio-technical aspects of` requirements-driven collaboration among agile teams through an online survey conducted on industry practitioners, as communication and awareness. Secondly, a framework was proposed to study the identified socio-technical aspects of requirements-driven collaboration among agile teams and a prototype was developed to partially automate the framework. Thirdly, an empirical investigation was conducted by studying four IT-based projects carried out in four different organizations. This empirical investigation led to the practical implementation of the proposed framework to study the requirements-driven collaboration among agile teams. This research was validated from two perspectives. From the academic perspective, the results show that the framework is structurally acceptable. From the industrial perspective, an applicability validation was performed to assess the application of the proposed framework while a utility validation was conducted to gauge the usefulness of the proposed framework. The study provides implications for both research and industry practitioners in the form of further research and tool development for agile teams collaboration and performance analysis underlying the concepts proposed in this study

    Maģistra darba nosaukums ir “Sūfisma interpretācija Inājata Hāna traktātā “Sūfiju vēstījums par garīguma brīvību””. Darba tēma ir Inājata Hāna traktāta “Sūfiju vēstījums par garīguma brīvību” (A Sufi Message of Spiritual Liberty) (1914) analīze par autora sūfisma mācības izpratni un tās subjektīvu atspoguļojumu traktātā. Izvēloties pētīt sūfisma ideju interpretāciju šajā Inājata Hāna traktātā, maģistra darba autore ir vēlējusies padziļināti izprast Hāna piedāvāto sūfisma teorētisko interpretāciju un analizēt to ietekmējušos faktorus. Darba mērķis ir, analizējot sūfisma mācības teorētisko izklāstu Inājata Hāna traktāta, identificēt Inājata Hāna sūfisma interpretācijā atrodamos aizguvumus no dažādām reliģiju un garīguma mācībām. Pieņēmums – Inājata Hāna traktātā aprakstītā sūfisma filosofija ir islāma un dažādu jauno reliģisko kustību sinkrētisms, kas ietērpts sūfisma terminoloģijā. Galvenie secinājumi – neskatoties uz to, ka Inājats Hāns savā traktātā apraksta sūfisma mācību kā universālu filosofiju, kā arī integrējis savā sūfisma interpretācijā dažu citu reliģiju svētos rakstus, lielākoties visu viņa izpratni par sūfismu šajā traktātā caurvij spēcīga islāma ietekme. Darbā izvirzītais pieņēmums nepiepildījās. Darba struktūra ir kopsavilkums latviešu un angļu valodā, ievads, 5 daļas, 11 nodaļas, noslēgums, literatūras saraksts. Darba izstrādē izmantoti 2 avoti un 70 uzziņu literatūras avoti. Darbā ir 80 lapas. Pirmajā daļā “Pretrunīgums traktāta ārējos komponentos” ir apskatīta Inājata Hāna divējādā pieeja sūfisma skaidrošanā, vienlaikus izmantojot islāma terminoloģiju un citu reliģiju tekstus. Otrajā daļā “Inājata Hāna pievēršanās garīgumam” ir apskatīts Hāna ceļš līdz kļūšanai par sūfisma skolotāju. Trešajā daļā “Dieva raksturojums Inājata Hāna mācībā” ir apskatīts, kā Hāns uztver un apraksta Dievu. Ceturtajā daļā “Inājata Hāna sūfisma galvenie teorētiskie pīlāri” ir apskatīti traktātā visbiežāk pieminētie Hāna piedāvātās garīguma mācības aspekti. Piektajā daļā “Inājata Hāna piedāvātā sūfisma prakse” apskatītas Hāna piedāvātās metodes sūfisma apgūšanai.The title of the master’s thesis is “Interpretation of Sufism in Inayat Khan's treatise “A Sufi Message of Spiritual Liberty””. The topic of the work is the analysis of Inayat Khan’s treatise “A Sufi Message of Spiritual Liberty” (1914) about the author’s understanding of the teachings of Sufism and its subjective reflection in the treatise. By choosing to study the interpretation of the ideas of Sufism in this Inayat Khan’s treatise, the author of the thesis wanted to understand the theoretical interpretation of Sufism offered by Khan and analyze the factors that influenced it. The aim of this work is by analyzing the theoretical representation of Sufism in the treatise of Inayat Khan, to identify the borrowings from various religious and spiritual teachings found in Khan’s interpretation of Sufism. Assumption – the philosophy of Sufism described in Inayat Hahn’s treatise “A Sufi Message of Spiritual Liberty” is a syncretism of Islam and various New Religious movements clothed in Sufi terminology. Main conclusions – despite the fact that Inayat Khan in his treatise describes the teachings of Sufism as a universal philosophy and has integrated sacred texts from other religions into his interpretation of Sufism, for the most part, his entire understanding of Sufism in this treatise is permeated by a strong Islamic influence. The assumption put forward in the work was not fulfilled. The structure of the work is a summary in Latvian and English, introduction, 5 parts, 11 chapters, conclusion, bibliography. In the development of the work were used 2 sources and 70 literary sources. The work consists of 80 pages. The first part, “Contradiction in the External Components of the Treatise,” discusses Inayat Khan’s twofold approach to explaining Sufism while simultaneously using Islamic terminology and texts from other religions. The second part, “Inayat Khan’s Conversion to Spirituality” discusses Khan’s journey of becoming a teacher of Sufism. The third part, “Characterization of God in Inayat Khan's Teaching” discusses Khan’s perception and description of God. The fourth part, “The Main Theoretical Pillars of Inayat Khan's Sufism”, discusses the most frequently mentioned aspects of Khan’s spiritual teaching in the treatise. The fifth part, “Practice of Sufism proposed by Inayat Khan”, examines Khan’s proposed methods for learning the teachings Sufism. Keywords: Sufism, Sufis, Neo-Sufism, Inayat Khan, Islam

    A reflection on agile requirements engineering: solutions brought and challenges posed

    No full text
    The software development industry has rapidly accepted agile methods. Empirical studies suggest that due to their flexible and emergent nature, agile methods brought solutions to several chronic problems of traditional software development methods. One among the many is the acceptance of requirements changes at later stages of development. However, knowledge about the solutions that agile brought to requirements engineering (RE) is fragmented. Also, little is known about whether the agile philosophy, while introducing solutions to well-known RE problems from the past, has unintentionally opened new challenges. This paper offers a reflection on this matter. Based on the results of our recently published systematic review on agile RE, we reflect on the differences of ‘traditional’ and agile RE and the practices adopted by the latter, on the solutions and challenges of agile RE, and on some implications that agile RE might have posed for research and practice

    Safety and security risks management process for cyber‐physical systems: A case study

    No full text
    Cyber-physical systems (CPS) are applicable in emerging industries such as health, energy, autonomous vehicles, and Industrial Internet of Things (IIOT). In CPS the physical assets, that is, actuators and sensors, etc. communicate with each other over a messaging protocol. This communication process of CPS makes them vulnerable to cyber-attacks which challenge the system safety, making security and safety two major concerns for CPS. Both safety and security risks are considered separately in literature. However, the International Society of Automation (ISA) focuses on the alignment of security and safety risks of CPS. Weak or no alignment in safety and security of a system may result in an inefficient or partially protected system which could end up in disasters. This pressed the need for an integrated safety-security risk management process. For this purpose, we used a tetra packaging case study to (i) examine the vulnerabilities of CPS by running the risk management process, (ii) identify safety-security requirements, and (iii) align retrieved safety-security requirements with the relevant standards. The results show (i) safety hazards and security risks along with their severity and priority, (ii) mitigation guidelines are provided by consulting IEC 61508, and (iii) 15 safety-security requirements are identified and are aligned with ISO9001 Packaging and labeling machine standard.</p

    Security-Based Safety Hazard Analysis Using FMEA: A DAM Case Study

    No full text
    Safety and security emerge to be the most significant features of a Cyber-Physical System (CPS). Safety and security of a system are interlaced concepts and have mutual impact on each other. In the last decade, there are many cases where security breach resulted in safety hazards. There have been very few studies in the literature that address the integrated safety security risk assessment. Since, the need of the time is to consider both safety and security concurrently not even consequently. To close this gap, we aim to: (i) perform hazard analysis using Failure Mode Effect Analysis (FMEA) of a cyber physical system case i.e., Dam case study, and (ii) perform risk identification, risk analysis and mitigation for the said case. As a result, we extracted the potential failure modes, failure causes, failure effects, and the risk priority number. In addition, we also identified the safety requirements for the modes of the subject.</p
