Using Agile Project Management in the Design and Implementation of Activity-Based Costing Systems

The success of a costing system is dependent on its appropriation and assimilation by the organization. The involvement of all stakeholders from the early stages of design and implementation plays a critical role in this process. In this paper, the use of agile project management is investigated to support the design and implementation of more effective costing systems. A Design Science Research approach was followed to apply an agile project management approach—the Scrum methodology—to the design and implementation of an Activity-Based Costing (ABC) system in a hospital imaging service. The proposed methodology identifies the roles, the events, and the most important artifacts in the design and implementation of costing systems. Research results show that applying agile project management principles contributes to a higher degree of acceptance of the costing system by the operating personnel, as well as by top management. It was also found that a simpler model (result of sprint 5), instead of a more detailed one (proposed for sprint 4), may better fit the interests of the decision makers and the organization’s accounting and information systems. Thus, the best costing system is not necessarily the most complete or accurate, but the one that is most useful and adapted to the organization’s needs. The definition of the product backlog, the several sprints, and the iterative process were critical in this process. The adoption of the Scrum methodology allowed the design and implementation of an ABC system more adapted to the organization’s needs and allowed the early identification of problems that, traditionally, are only perceived at the end of the implementation process, therefore increasing the performance and economic sustainability of organizations.

Scrum: An Effective Software Development Agile Tool

Present days the world is surviving with respect to the software products. The development of the software product is a challenging issue and to run with the competitive world rapid development of software products are necessary. It is not enough to go with the traditional software development products like waterfall model, spiral model and all. Here we proposed the SCRUM TOOL, one of the effective techniques of Agile Methodology. Agile is an incremental and timeframe iterative approach. It supplies the software developers with a working framework for traditional software development practices like waterfall model. Although the traditional models are best suited for small products where there is no changing requirements but not suitable for the products which have rapidly changing requirements and thus here we recommend SCRUM methodology. In this approach we can develop the software product by taking the regular feedback from the customer through review meetings. So whenever the customer requests the changes we can upgrade the product with respect to those changes and can also develop the product more efficiently and rapidly.

ГРАФОДИНАМІЧНЕ МОДЕЛЮВАННЯ УПРАВЛІННЯ СИТУАЦІЯМИ В ІННОВАЦІЙНИХ ПРОЄКТАХ НА ОСНОВІ МЕТОДОЛОГІЇ SCRUM

Ambiguous situations affect the progress of the project in any area. They are unpredictable in nature and require consideration of fairly new and complex factors that to varying degrees determine the effectiveness of the project. The article considers the issue of building a model of graph-dynamic simulation of situation management in innovative projects based on Scrum methodology by studying the binary game in the conditions of conflict between stakeholders. After analyzing the project participants based on a flexible Scrum methodology and considering possible contradictions between different stakeholders of the project, the authors have used the technique of binary game based on scenario communications to develop the model. Knowledge and skills application of the situational approach in the conditions of flexible Scrum methodology will provide opportunities to the project manager to radically change a situation in the project and to achieve the motivated performance of each task. The authors offer a formalized presentation of the procedure for selecting the optimal solution in project management in the implementation of a flexible Scrum methodology. This takes into account all the features of flexible Scrum methodology. The procedure of making the optimal decision on the basis of research of binary game between the interested parties in the conditions of contradiction is offered. A set of scenarios is developed to help overcome the crisis situation, and possible alternatives are explored. The use of these approaches in the implementation of flexible Scrum methodology provides support for decision-making in crisis situations of possible conflicts with existing constraints on financial and time resources. The result of applying the developed model is to increase the efficiency of the project by reducing the loss of time in the project and overspending of financial resources.

Prioritization of IT Product Backlog Items Using Decision Support Systems

The article focuses on the application of decision support systems for prioritization of product backlog items in IT projects implemented using the Scrum methodology. The study identified the features of prioritization of different types of the product backlog items — user stories, epics and themes. It is justified that high-level product backlog items (epics and themes) require comprehensive prioritization, due to the following reasons. First, high-level product backlog items are particularly important because they determine the planning and implementation of detailed user stories within individual sprints. Second, any high-level item can be considered in terms of different criteria. Third, the implementation of epics and themes takes longer time compared to the implementation of user stories, so it is necessary to take into account possible future states of the project's environment. Fourth, prioritizing epics and themes requires increased objectivity and validity, so group decision making with participation of several experts seems reasonable. Taking into consideration the aforementioned features the conclusion regarding limitations of existing methods of prioritization is made. It is argued that prioritization of high-level product backlog items (epics and themes) may be performed using multi-criteria decision making methods with availability of several problem situations (possible future states of the environment), as well as involvement of several experts. The idea of applying decision support methods and systems is illustrated on the appropriate example. It is also argued that increased consumption of time and resources related with setting and solving decision support tasks may be considered as acceptable for high-level product backlog items.

Understanding the Interactions between the Scrum Master and the Development Team: A Game-Theoretic Approach

Scrum methodology is widely used in the information technology (IT) industry for the purposes of team-based iterative software development. However, limited studies have been conducted to explore the nature of interactions between a Scrum Master and other team members and the effect of these interactions on team effectiveness. The aim of this study is to understand the interactions between the Scrum Master and other team members in an educational setting and propose and demonstrate an application of cooperative game theory for the same. Cooperative game theory can model scenarios where other team members can benefit from cooperating. Through the lens of the cooperative game-theoretic model, we investigated the strategies employed by the Scrum Master and other team members when involved in a semi-capstone IT project. Specifically, the study explored the team interaction between a Scrum Master and other team members at three different levels of team effectiveness: least effective, partially effective, and most effective. Our results indicate that a Scrum Master should be active to maximize their payoff as well as the teams’ overall payoff. Contrary to this, other team members should be active in the most and partially effective teams, while being passive in the least effective teams at higher costs of interpersonal relations and the processes. The results of the study represent a novel application of game-theoretic modeling for understanding the Scrum Master and other team member interactions. These results are applicable not just in an educational setting but also to the wider area of software development by identifying the right set of strategies by the Scrum Master, and other team members in order to help IT professionals to maximize their payoff.

Penerapan Metode SCRUM dalam Pengembangan Sistem Informasi Layanan Kawasan

The development of technology is very influential in the business processes of an organization to be able to carry out its duties and functions. As a government agency engaged in research, the Indonesian Institute of Sciences (LIPI) needs to make organizational changes to support its vision as a world-class research institution. One of the first steps taken is reorganizing and redistributing employees that have a high impact on the business process of service to employees because the supporting resources are placed corporately and no longer in the work units. To deal with this problem, we developed a Regional Service Information System using the Scrum methodology. The output is a web-based software that facilitates service requests needed by employees, ranging from service submission, processing by the Area Manager and Central Manager, to being received again by the service requester. The Regional Service Information System is expected to be a solution to the problems that arise as a result of the redistribution of employees at LIPI and to improve the effectiveness of employees as the research supporting resources.

Computational method for monitoring pauses exercises in office workers through a vision model

A sedentary routine at work can cause various muscular, skeletal or visual diseases, however these can be prevented with what is known as active pauses. This article is intended to illustrate how software can help reduce the risk of occupational disease due to the sedentary lifestyle of an office job, for this purpose a web application was developed under the SCRUM methodology, which makes use of the TensorFlow, Flask PoseNet model and python, for an active pause control application which is a proven practice of reducing the type of diseases already mentioned. With these tools it was possible to develop an algorithm capable of comparing two human figures; which serves to compare whether the user of the program is performing or not correctly performing the active pause exercise, with an average error squared on the order of 10−32. Finally, The application can keep track of the figure and exercises performed by the user just by using the user personal webcam and the comparison algorithm developed, leaving behind the use of tools such as Kinect.

Learning Process of Agile Scrum Methodology With Lego Blocks in Interactive Academic Games: Viewpoint of Students

The rapid growth of Information Technology led to the development of a multitude of smartphone systems worldwide. As a result, the number of educational institutions offering courses in areas such as programming and software engineering increased. However, traditional processes for software development did not keep pace with changing technologies. In the last few years, software development became more dynamic and iterative, requiring stakeholders to work as a team and deliver higher quality projects in less time, by using methods such as Agile Development (e.g., Scrum and Extreme Programming (XP)). Although some institutions approach this content in graduation courses, many students and professor are indifferent towards it, resulting in low enthusiasm and practice. This article presents the real case of a classroom activity to teach Scrum concepts by using Lego blocks. At the end of the classes, students were asked to rate the effectiveness of the activity. The results showed that dynamic games and palpable activities are more effective than theoretical or video lessons.

Implementing ISO/IEC 29110 to reinforce four very small entities of Mexico under an agile approach

Very small entities (VSEs) of software development have had a significant demand and economic impact in recent years, because most of them are the software producers for medium and big companies in order to satisfy the growing demand of software. In this context, it is important to ensure that they produce quality software to successfully meet the market needs. This task relies on having the knowledge and the experience to implement proven practices, which are contained in quality models and standards, to be able to develop quality software, while increasing their productivity and keeping or reducing their costs. A description of the implementation of ISO/IEC 29110 in Mexico, specifically at Zacatecas State is presented. This implementation was done as a strategy to increase the competitiveness of them. The study includes both, the strategy established to deploy the knowledge and the method followed to implement the ISO/IEC 29110 in four VSEs that uses scrum methodology as agile approach. The results show that the implementation of ISO/IEC 29110 was easy and with a high acceptance due to the benefits detected in the reinforcement of the VSEs’ processes without changing the way they work and solving their problems.

Agile Scrum Issues at Large-Scale Distributed Projects

The agile model is a very vast and popular model in use in the software industry currently. It changes the way software is developed. It was introduced in 2001 to overcome deficiencies of software development in a workshop arranged by researchers and practitioners who were involved with the agile concept. They introduced the complete agile manifesto. The agile model has main components that make it more viable for use in well-organized software development. One of these is scrum methodology. The reason for the agile-scrum popularity is its use for small-scale projects, making small teams and allows change requests at any stage of a project from the client. It works for client satisfaction. Instead of so much popularity and distinctive features, agile-scrum also has some limitations when used for large scale projects development that makes it less efficient for development. This article discusses the agile-scrum methodology and its limitations when using for large-scale project organization.

АНАЛІЗ І МОДЕЛЮВАННЯ БІЗНЕС-ПРОЦЕСІВ КОМП’ЮТЕРНОЇ КОМПАНІЇ

Modern enterprises are constantly forced to improve their activities. This requires the development of new technologies and techniques for doing business, improving the quality of the final results of activities and introducing new, more effective methods of management andorganization of enterprises. The analysis of existing methodologies for modeling business processes and software development models is carried out, based on which the company’s business processes arereengineered. The reorganization of the organizational structure of the computer company. Given the shortcomings of the functional structure of the organization, another form of employee subordination is proposed - matrix. The application of neural networks for solving many problems of game development, modeling and analysis of business processes “as is”, diagnostics of enterprise problems, modeling of business processes “as it should be”, a comparative analysis of projects in MS Project is carriedout. The manager of the department of artificial intelligence, which manages various areas of activity in the field of artificial intelligence, has been added to the organizational structure. The reorganization of the company's business processes is based on the Scrum and XPmethodology. The “as is” project has increased the load on programmers, this is due to the fact that more time is devoted to fixing errors after implementing the entire development process than afterimplementing each sprint while maintaining the same productivity of software development. The project “as it should be” increased the load on the artificial intelligence manager in accordance with the Scrum methodology. The result of the research is a set of business process models and recommendations for improving the enterprise.The practical value of the proposed study lies in the fact that based on the provided business process models, it becomes possible to create the most competitive computer game development company that will bring high profits and will be structurally and functionally correctly organized.

A software to prevent delirium in hospitalised older adults: development and feasibility assessment.

non-pharmacological interventions to prevent delirium are useful in hospitalised older adults. However, they are poorly implemented in clinical practice. We aimed to develop a software for bedside use by hospitalised older adults and to improve their access to these interventions. a transdisciplinary team composed of healthcare professionals, designers, engineers and older adults participated in the development of the software. Scrum methodology was used to coordinate the work of the team, and the software was evaluated in a feasibility study. a software for touchscreen mobile devices that supports Android 5.0 or later was produced, including modules for time-spatial re-orientation, cognitive stimulation, early mobilisation, sensorial support use promotion, sleep hygiene and pain management optimisation. Horizontal disposition, use of colour contrast and large interaction areas were used to improve accessibility. The software's usability and accessibility were evaluated in 34 older adults (average age 73.2 ± 9.1years) showing that 91.1% of them got access to all the software functions without previous instructions. The clinical feasibility assessment showed that 83.3% of the 30 enrolled hospitalised patients (76 ± 8years) completed the 5-day protocol of software usage during hospitalisation. Software use was associated with a decreased trend in delirium incidence of 5 of 32 (15.6%) at baseline to 2 of 30 (6.6%) after its implementation. a highly accessible and implementable software, designed to improve access to non-pharmacological interventions to prevent delirium in hospitalised older adults, was developed. The effectiveness of the software will be evaluated in a randomised clinical trial.

ОСОБЛИВОСТІ ПРОЕКТУВАННЯ WEB-ОРІЄНТОВАНИХ ІНФОРМАЦІЙНИХ СИСТЕМ НА ОСНОВІ ГНУЧКОЇ МЕТОДОЛОГІЇ SCRUM

The article deals with the possibility of using flexible Scrum methodology at the stage of designing Web-oriented information systems and the features of designing under Scrum conditions. Designing is a decisive step in the development of any information systems, because it is this stage that lays the foundations and ways to implement ideas which determine the functioning of the system in the future. Therefore, in the process of designing Web-oriented information systems, it is important to observe the basic principles of design, as well as the schemes of implementation of this process. However, in order to achieve product stability, security and functionality sustainability, it is necessary to apply such methodology in the course of development, which will allow the constant monitoring and communication between project team members, ensuring the design process itself. The experience of designing Web-oriented information systems now shows that it is logically complex, requiring the expenditure of much labour and time work which requires highly qualified specialists who are members of the project team and are involved in this stage. Productivity, constant monitoring and interchangeable adapters are important. The basic processes of designing Web-oriented information systems based on the application of Scrum methodology are explored, the advantages and disadvantages are considered, as well as the roles, artifacts and processes are analyzed and substantiated. The ways of the efficiency increase and shortcomings elimination during the implementation of designing processes are presented. In conclusion it is necessary to mention that the use of flexible Scrum methodology both in designing and project management of Web-oriented information systems will ensure the possibilities of obtaining the qualitative final product and optimal resources and time use.

A teacher perspective on Scrum methodology in secondary chemistry education.

Scrum methodology is a novel framework for teaching intended to scaffold students' learning process when they work on complex, real-world tasks. It is originally a project management framework frequently used in business and industry to manage projects. Scrum methodology is increasingly used in educational contexts. Yet, it is also a rather complex framework and more insight in how teachers understand and implement Scrum methodology is needed. Twelve teachers attended a professional development program and simultaneously implemented Scrum methodology in their chemistry lessons. Teachers' didactical expertise and pedagogical expertise appeared to play a key role during the implementation process, whereas teachers' subject matter expertise, and other factors such as teaching context, teaching experience and personal biography seemed to be less important. Didactical and pedagogical expertise enhances teaching with Scrum: it supports the implementation as well as increases its effectiveness, independently of teaching context, experience and personal biography. This would mean Scrum methodology offers possibilities for teachers to enhance and enrich their teaching practice.

Effects of Scrum methodology on students’ critical scientific literacy: the case of Green Chemistry

Secondary science education plays a key role in students’ process to become scientifically literate citizens. However, teaching students to acquire the necessary skills and knowledge to deal with complex societal issues is challenging. This paper reports about a study in which Scrum – a methodology to manage complex projects – was implemented in secondary chemistry classrooms to increase students’ conceptual understanding as well as their critical scientific literacy. A quasi-experimental design was used with 198 Grade 11 students from eight different classes. The experimental condition (99 students, 4 classes, 25 groups with 3 or 4 students, 2 teachers) used Scrum methodology during a context-based course on Green Chemistry. The comparison condition (99 students, 4 classes, 29 groups of 3 or 4 students, 3 teachers) completed the same module about Green Chemistry, without using Scrum methodology. At the end of the course students formulated a written advice on the greenest synthesis of adipic acid. A pre-test on prior knowledge of Green Chemistry principles and a post-test on conceptual understanding of the chemistry concepts involved were administered. In addition, the Standard Observed Learning Outcomes taxonomy (SOLO) was used to analyse the quality of the written advices as a measure for students’ critical scientific literacy. Students from the experimental condition outperformed their peers from the comparison condition in their conceptual understanding. Moreover, the quality of the advices of students from the experimental condition were rated higher than the quality of advices of students in the comparison condition. These findings are discussed and connected to Scrum methodology as teaching approach to scaffold both students’ conceptual understanding and its potential to promote the development of their critical scientific literacy.
