Complementing Measurements and Real Options Concepts to Support Inter-iteration Decision-Making in Agile Projects
Agile software projects are characterized by iterative and incremental development, accommodation of changes and active customer participation. The process is driven by creating business value for the client, assuming that the client (i) is aware of it, and (ii) is capable to estimate the business value, associated with the separate features of the system to be implemented. This paper is focused on the complementary use of measurement techniques and concepts of real-option-analysis to assist clients in assessing and comparing alternative sets of requirements. Our overall objective is to provide systematic support to clients for the decision-making process on what to implement in each iteration. The design of our approach is justified by using empirical data, published earlier by other authors
Measuring Software Process: A Systematic Mapping Study
Context: Measurement is essential to reach predictable performance and high capability processes. It provides
support for better understanding, evaluation, management, and control of the development process
and project, as well as the resulting product. It also enables organizations to improve and predict its processâs
performance, which places organizations in better positions to make appropriate decisions. Objective:
This study aims to understand the measurement of the software development process, to identify studies,
create a classification scheme based on the identified studies, and then to map such studies into the scheme
to answer the research questions. Method: Systematic mapping is the selected research methodology for this
study. Results: A total of 462 studies are included and classified into four topics with respect to their focus
and into three groups based on the publishing date. Five abstractions and 64 attributes were identified,
25 methods/models and 17 contexts were distinguished. Conclusion: capability and performance were the
most measured process attributes, while effort and performance were the most measured project attributes.
Goal Question Metric and Capability Maturity Model Integration were the main methods and models used
in the studies, whereas agile/lean development and small/medium-size enterprise were the most frequently
identified research contexts.Ministerio de EconomĂa y Competitividad TIN2013-46928-C3-3-RMinisterio de EconomĂa y Competitividad TIN2016-76956-C3-2- RMinisterio de EconomĂa y Competitividad TIN2015-71938-RED
The characteristics of the Computer Supported Collaborative Learning (CSCL) through Moodle: a view on studentsâ knowledge construction process
Computer Supported Collaborative Learning (CSCL) is based on the pedagogical process of observation where students will learn progressively through active group interaction. CSCL is an emerging branch of the learning sciences concerned with studying on how people can learn together with the help of computers. Thus, this research was conducted to measure the characteristics of the CSCL learning environment through Moodle that assists the process of studentsâ knowledge construction during the teaching and learning process. The CSCL learning environment is an educational learning system which develops to help the teachers and students in managing School Based Assessment (SBA) in selected secondary school in Malaysia. Samples involved two groups of students and two Technical and Vocational Education and Training (TVET) teachers from two different schools. A total of 61 students, who were taught using CSCL approach through Moodle, underwent the process of teaching and learning using their school computer laboratory. The finding shows that the characteristics of the CSCL learning approach that used in this learning environment for the first group are at a high level with overall mean of 4.17 and the second group at moderate level with overall mean of 3.62. The result proves that the characteristics of the CSCL learning environment help students to build their knowledge during teaching and learning process at the high level with an overall mean score of 3.87. The mean of these two groups may vary according to studentsâ background, as well as learning environment facilities. Although, CSCL leads to studentsâ self-development, improving learning quality, sharing knowledge and assisting studentsâ in the process of building their knowledge, implementation of CSCL must first considering the technology relevant facilities, especially computer laboratory and internet accessibility in school. The implication is that designing a good CSCL must also taking into account the targeted usersâ cultural background and socioeconomic factor

Using the theory of planned behavior to explore environmental behavioral intentions in the workplace
This paper presents a study using the theory of planned behavior (TPB) to explore environmental behavioral intentions in a workplace setting. The first stage of the research process was the development of a questionnaire covering TPB constructs, their antecedent beliefs, and environmental behavioral intentions across three scenarios (switching off PCs every time employees left their desks for an hour or more; using video-conferencing for meetings that would otherwise require travel; and recycling as much waste as possible), using best practice guidelines to ensure that it was specific and precisely defined for the target population. This was then administered to N = 449 participants, with the resulting dataset used to test hypotheses relating antecedent beliefs to behavioral intentions via the potentially mediating effect of TPB constructs. TPB constructs were found to explain between 46% and 61% of the variance in employee intentions to engage in three environmental behaviors, and to mediate the effects of specific antecedent beliefs upon employee intentions to engage in these behaviors. The results form a basis upon which interventions could be developed within the host organization, and are discussed in relation to their implications, in terms of theory, practice and future research
What is the Connection Between Issues, Bugs, and Enhancements? (Lessons Learned from 800+ Software Projects)
Agile teams juggle multiple tasks so professionals are often assigned to
multiple projects, especially in service organizations that monitor and
maintain a large suite of software for a large user base. If we could predict
changes in project conditions changes, then managers could better adjust the
staff allocated to those projects.This paper builds such a predictor using data
from 832 open source and proprietary applications. Using a time series analysis
of the last 4 months of issues, we can forecast how many bug reports and
enhancement requests will be generated next month. The forecasts made in this
way only require a frequency count of this issue reports (and do not require an
historical record of bugs found in the project). That is, this kind of
predictive model is very easy to deploy within a project. We hence strongly
recommend this method for forecasting future issues, enhancements, and bugs in
a project.Comment: Accepted to 2018 International Conference on Software Engineering, at

Due to pervasiveness of ICT's, most of collaboration can be performed through communication media channels such as discussion forums, social networks, etc. The emotive state of the users while they carry out their activity such as collaborative learning at Universities or project work at enterprises and organizations influences very much their performance and can actually determine the final learning or project outcome. Therefore, monitoring the users' emotive states and using that information for providing feedback and scaffolding is crucial. To this end, automated analysis over data collected from communication channels is a useful source. In this paper, we propose an approach to process such collected data in order to classify and assess emotional states of involved users and provide them feedback accordingly to their emotive states. In order to achieve this, a fuzzy approach is used to build the emotive classification system, which is fed with data from ANEW dictionary, whose words are bound to emotional weights and these, in turn, are used to map Fuzzy sets in our proposal. The proposed fuzzy-based system has been evaluated using real data from collaborative learning courses in an academic context.Peer ReviewedPostprint (author's final draft
Overcoming Barriers in Supply Chain AnalyticsâInvestigating Measures in LSCM Organizations
While supply chain analytics shows promise regarding value, benefits, and increase in performance for logistics and supply chain management (LSCM) organizations, those organizations are often either reluctant to invest or unable to achieve the returns they aspire to. This article systematically explores the barriers LSCM organizations experience in employing supply chain analytics that contribute to such reluctance and unachieved returns and measures to overcome these barriers. This article therefore aims to systemize the barriers and measures and allocate measures to barriers in order to provide organizations with directions on how to cope with their individual barriers. By using Grounded Theory through 12 in-depth interviews and Q-Methodology to synthesize the intended results, this article derives core categories for the barriers and measures, and their impacts and relationships are mapped based on empirical evidence from various actors along the supply chain. Resultingly, the article presents the core categories of barriers and measures, including their effect on different phases of the analytics solutions life cycle, the explanation of these effects, and accompanying examples. Finally, to address the intended aim of providing directions to organizations, the article provides recommendations for overcoming the identified barriers in organizations
Presenting Modified Servqual Model to Evaluate Flight Attendant Services: Iran Air case study
Purpose: The investigation of the customer`s viewpoints and utilizing their ideas and expectations in improving the quality of the products, has turned out to be one of the key concerns of the companies working in all fields. Airline industry as one of the most extensive modes of transportation should be strictly accurate in providing services to their customers. This article attempts to investigate important dimensions from passengers' point of view and present a model which would evaluate the flight attendant's performance. Design/methodology: In order to achieve this purpose, on the basis of the literature and experts' and passengers' point of view, the SERVQUAL model has been modified with 26 factors in 6 dimensions. Then 300 data have been gathered for the Factor Analysis Model. Findings: As a result, a model with high goodness of fit has been developed which could be used as a tool of measuring quality of service with a high degree of certainty. In the end, running the model in Iran air, most differences were as below: 1-Improvement 2-Responsiveness 3-Empathy 4-Assurance 5-Tangibles 6-Reliability. Originality/value: In general, in this model, all services with which employees are involved are observed. However, the main issue in this research is related to attendant team. Consequently, considering that many of these indicators have different meanings in assessing customer satisfaction in relation to the performance of flight attendant; modifications should be made to the dimensions of the SERVQUAL model.Peer Reviewe
