A Quantitative Study of Waterfall and Agile Methodologies With the Perspective of Project Management

Software engineering is used in order to develop larger and complex software products. As software product is needed in almost all the industries, software engineering becomes really important. Software development can be done through various software development life cycle (SDLC) models like waterfall model, agile model, spiral model, prototype model, etc. SDLC is a framework that defines the tasks that to be performed at each step in the development process. Authors are mainly focusing on two models (i.e., waterfall and agile model). Waterfall model is a serial model which follows a strict sequence. Agile methodology can be divided into scrum methodology and extreme programming. Scrum methodology mainly focuses on how to manage tasks in a team-based environment. Scrum consists of three main roles. They are scrum master, product owner, and scrum team. While comparing both the models, the main difference obtained is waterfall does not allow any customer involvement while agile does allow it.

Development of Social Studies Learning Outcomes with Tajhin Peddhis-Based Etnopedagogy Approach

The purpose of this study was to describe social studies learning outcomes with an Ethno pedagogy approach based on the tajhin pheddis tradition. The research method is classroom action research with the Spiral Model from Kemmis and Taggart. In general, four stages are usually passed, namely: Planning, Acting, Observing, and Reflecting. The subjects or informants are social studies teachers and Class VII students at Madrasah Tsanawiyah. This study's techniques and data collection tools were observation and interview techniques. Student learning outcomes have increased between cycle 1 and cycle 2. The increase in learning outcomes can be seen from the average cycle 1 of 62, 5. The average value in cycle II has increased by 79, 5, while the average presentation of completeness in the cycle This II increased to 80% of students who completed above the KKM score. Based on the average value and the percentage of classical learning completeness, it can be concluded that social studies learning with an ethnopedagogic approach based on the tajhin pheddis tradition can improve student learning outcomes in social studies subjects. Learning with an ethnopedagogic approach through the tajhin tradition pheddis can be an approach in social studies learning that is meaningful learning. It is shown that the study results indicate an increase in student learning outcomes at MTs AL-Ikhlas Kuala Mandor B.

SUBSTANTIATION OF DEVELOPMENT STAGES OF THE INFORMATION SYSTEM FOR SUPPORT OF TESTS OF ARMAMAENT AND MILITARY EQUIPMENT OF THE ARMED FORCES OF UKRAINE

One of the important areas of support and development of the state's defense capabilities is to equip the armed forces with modern armament and military equipment (AME). In recent years, due to the situation in eastern Ukraine, there has been a significant increase in the pace of development and adoption of the newest models of AME. The process of harmonizing national standards with NATO standards also contributes to this. Naturally, it causes an increase in the need for timely and high-quality testing of AME samples. Accordingly, the task of improving the efficiency of all processes that accompany the testing of defense products is urgent. The article considers the problem of practical development of information system for support of tests of AME, the purpose of which is to automate information processes in the preparation and conduct of tests, which should reduce time and labor costs at all stages of testing. Based on the previously substantiated spiral model of software product development and the concept of building an information system for test support, a step-by-step plan for the implementation of the information system is proposed. The system of requirements to the prototype of the information system with limited functionality is formulated, according to which the rating estimation of need and possibility of prioritized realization of the basic functional modules of the information system is carried out. Based on the requirement of functional connectivity of the modules, the information system composition on the next turn of the life cycle spiral model is substantiated. The step-by-step approach during creation and provisioning of databases and data registers with information are considered. As the information system develops, the transition to an incremental model of software product development is not excluded. It is expected that the automation of information processes related to the planning and conducting of tests, as well as the processing of test results and preparation of reporting documentation can positively impact the overall efficiency of the organization and conducting of tests, as well as ensure the proper quality of results.

Learning processes and knowledge transfer in the upward spiral model: an empirical assessment of springboard multinational enterprises

Purpose The springboard theory for multinational enterprises and the upward spiral model address the expansion of emerging countries’ multinational enterprises (MNEs) abroad as a set of resource-building stages. This paper aims to analyze this model by qualifying knowledge flows in three domains: learning effects, transfer flows and global connections. Design/methodology/approach The authors use 2018 data from the ORBIS database to identify evidence concerning the springboard MNE (SMNE) phenomenon. The authors select MNE firms from 93 emerging economies with presence in 71 developed and 93 developing countries. In addition, the authors differentiate between the levels of technological intensity of emerging market MNEs’ sectors. Findings The results highlight the existence of learning processes taking place in subsidiaries and feeding back into parent firms, as well as the existence of capability transfer from home to host units. Originality/value The main contribution is the addition of empirical evidence on the SMNE and specifically the upward spiral model, considering the micro-level and the productivity differences between parent firm and subsidiaries.

6. The curriculum

‘The curriculum’ argues that the generally accepted feeling is that the curriculum has been the jealously guarded province of teachers and education professionals, never to be penetrated by the common sense of politicians or public. This led to the establishment of the National Curriculum in the UK and a clutch of other European countries in the 1980s. Recent moves in the USA have aimed to introduce similar conformity, including the Common Core State Standards Initiative in 2010. This subject can't ignore the influence of ancient curricula and Jerome Bruner’s spiral model of the curriculum. What are the effects also of the hidden curriculum and the proliferation of tests on the curriculum?

“Wiraku Suci”: A Children’s App for Learning Hygiene Practices

Hygiene care is a basic human need, but very essential practice that must be taught since childhood. Personal hygiene involves making sure body parts are clean to avoid from health issues caused by poor cleanliness. Parents ultimately bear the responsibility to teach their children about cleanliness, and normally this is done by showing and practising hygiene care themselves. Nevertheless, it is not that easy to educate personal hygiene care to them, especially in the ages of four to six years old, because they are actively playing and exploring their environments. To aid parents, mobile learning app could be employed because hygiene habits can be shown via more engaging ways such as through pictures and video clips of personal hygiene care, simple drag and drop games, and pictorial quiz. In this study, a mobile learning app with game-based approach has been developed by following the software development life cycle Spiral model. During evaluation phase, a heuristic evaluation with five Computer Science lecturers was conducted to examine the usability of the app. Results from the evaluation were used as guidance to refine and improvise the app so that they will be usable and enjoyable for children.

Project Implementation Decision Using Software Development Life Cycle Models: A Comparative Approach

Selection of a suitable Software Development Life Cycle (SDLC) model for project implementation is somewhat confusing as there are a lot of SDLC models with similar strengths and weaknesses. Also, the solutions proffered among the researchers so far have been the qualitative comparative analysis of SDLC models. Hence, this paper proposes a comparative analysis of SDLC models using quantitative approach in relation to strengths and weaknesses of SDLC models. The study adapted comparative analysis and Software Development Life Cycle (SDLC) models features’ classification using ten characteristics such as project complexity, project size, project duration, project with risk, implementation/initial cost, error discovery, associated cost, risk analysis, maintenance and cost estimation. A quantitative measure that employs online survey using experts in software design and engineering, project management and system analysis was carried out for the evaluation of SDLC models. Purposeful Stratified Random Sampling (SRS) technique was used to gather the data for analysis using XLSTAT after pre-processing, taking into consideration both benefit and cost criteria. The overall performance evaluation showed that Spiral-Model is the best followed by V-Model and lastly Waterfall Model with comparative values of 38.63%, 35.76% and 25.61% respectively. As regards cost estimation, Waterfall Model is the most efficient with value of 41%, then V-Model with 31% and lastly Spiral Model with 28%. V-Model has great error recovery capability with value of 45% which is closely followed by Spiral Model with 37% and lastly Waterfall Model with 18%. The study revealed that, a model with efficient risk assurance does not guarantee efficient cost management. In the future work, more characteristics regarding SDLC models shall be considered.
